¶1 The petitioner, Patrick Dalton, seeks review of an unpublished court of appeals decision affirming his judgment of conviction and sentence and upholding the circuit court's order denying his postconviction motion.1 Dalton asserts that he is entitled to withdraw his no contest pleas because his trial counsel was ineffective for failing to move to suppress blood evidence collected without a warrant. In the alternative, he argues that he is entitled to resentencing because the circuit court relied on an improper sentencing factor.
¶2 Specifically, Dalton contends first that because police lacked the exigent circumstances necessary to draw his blood without a warrant, his counsel was ineffective for failing to move to suppress the evidence. He asserts next that the circuit *124court impermissibly lengthened his sentence for exercising his constitutional right to refuse a warrantless blood draw.
¶3 We conclude that exigent circumstances existed, permitting police to draw Dalton's blood absent a warrant. Accordingly, his counsel was not ineffective for failing to file a meritless motion to suppress.
¶4 We further conclude that the circuit court violated Birchfield v. North Dakota, 579 U.S. ----, 136 S.Ct. 2160, 2185-86, 195 L.Ed.2d 560 (2016),2 by explicitly subjecting Dalton to a more severe criminal penalty because he refused to provide a blood sample absent a warrant. Consequently, Dalton is entitled to resentencing.
¶5 Accordingly, although we agree with the court of appeals that Dalton's counsel was not ineffective, we nevertheless reverse and remand to the circuit court for resentencing.

¶6 This case arises from a single car crash in the Village of Richfield in which Patrick Dalton (Dalton) was the driver. After driving erratically and at speeds reaching approximately one hundred miles per hour, Dalton crashed his car into a ditch. Both Dalton and his passenger were injured.
¶7 Washington County sheriff's deputies responded to the scene of the crash at 10:07 p.m. on December 12, 2013. Upon arrival, the passenger in the car informed deputies that Dalton had been drinking and that Dalton was the driver of the car. When law enforcement arrived, Dalton was lying on the roof of the car, unconscious, and smelled of alcohol. Dalton was taken about a mile from the crash scene by ambulance, where he awaited the arrival of a Flight for Life helicopter.
¶8 After Dalton was driven away from the scene, Washington County Deputy Dirk Stolz remained and took the lead in investigating the scene. Deputy Stolz was accompanied by Deputies Charles Vanderheiden, Chad Polinske, and Michael Anderson. They were later joined by Lieutenant Robert Martin. Ten to 15 members of the Richfield Fire Department were also present, working to keep the area safe and blocking traffic to ensure officer safety.
¶9 While Deputy Polinske interviewed witnesses, Deputy Vanderheiden left the crash scene to await the helicopter with Dalton, who remained in the ambulance and unconscious. Deputy Vanderheiden arrived at the landing zone at 10:37 p.m. and testified that it took about 45 minutes from the time he got there for the helicopter to arrive. Upon its arrival, Flight for Life airlifted Dalton from the landing zone to Froedtert Hospital in Milwaukee.
¶10 Subsequent to Dalton being airlifted from the scene, Deputy Vanderheiden traveled to Community Memorial Hospital in Menomonee Falls to speak with the passenger. Leaving the crash scene at 11:14 p.m., Deputy Stolz drove to Froedtert Hospital in Milwaukee to reconnect with Dalton.
¶11 When Deputy Stolz arrived at Froedtert Hospital at 11:54 p.m., Dalton was receiving emergency treatment. After the treatment was complete, Deputy Stolz was able to speak to Dalton, who had regained consciousness.
¶12 Upon interacting with Dalton, Deputy Stolz observed that Dalton had glassy bloodshot eyes and the strong odor of alcohol *125emanating from his mouth. Dalton also appeared lethargic.
¶13 At approximately 12:05 a.m., nearly two hours after being dispatched to the crash scene, Deputy Stolz informed Dalton that he was under arrest and read Dalton the "Informing the Accused" form.3 Dalton refused a blood draw.
¶14 Believing that there were exigent circumstances that would obviate the need to obtain a warrant, Deputy Stolz then instructed a nurse to draw Dalton's blood, which was accomplished at 12:14 a.m. A subsequent blood test indicated that Dalton's blood alcohol content was 0.238 grams per 100 milliliters, nearly three times the legal limit of 0.08.
¶15 At the time Deputy Stolz read Dalton the Informing the Accused form, there were nine deputy sheriffs on duty in Washington County, along with one supervisor. Several of those who were present at the crash scene left and proceeded directly to other incidents that had taken place in the county that night requiring immediate attention.
¶16 Deputy Polinske, who had initially responded to the crash scene, ended his work day at 11:00 p.m. Deputy Anderson arrived on the scene at 10:15 p.m. and was cleared to leave at 11:42 p.m. He and one other deputy were subsequently dispatched to an auto theft call in the Village of Richfield.
¶17 Lieutenant Martin arrived at the scene at 11:01 p.m. and was cleared to leave at 11:46 p.m. After leaving the crash site he proceeded immediately to another auto accident that involved personal injury in which the driver had fled the scene, the vehicle was in the middle of the road, and power poles were downed. Three additional deputies accompanied Lieutenant Martin to this scene.
¶18 With Deputy Stolz in Milwaukee attending to Dalton and Deputy Vanderheiden in Menomonee Falls with the passenger, only two deputies were left to cover all of Washington County. One of these deputies was assigned to the northern half of the 432 square mile county, while the other was assigned to the southern half.
*126¶19 Dalton was ultimately charged with three offenses: operating while intoxicated (OWI) as a second offense, operating with a prohibited alcohol concentration (PAC) as a second offense, and operating after revocation (OAR). Dalton entered no contest pleas to the OWI and OAR charges, and the PAC charge was dismissed and read in.4 The case proceeded directly to sentencing.
¶20 At sentencing, the circuit court heard argument from the State and Dalton's counsel, as well as a brief statement from Dalton himself. In pronouncing its sentence, the circuit court observed the nature of the offense, addressing Dalton:
You certainly were driving like a maniac this night, and you were extremely uncooperative with the officers. You could have killed your friend, you could have killed yourself, or you could have killed someone completely innocent, and you acted in total disregard of those risks, endangering anyone else who was on the road at the time.
¶21 The circuit then proceeded to address Dalton's refusal to submit to a blood test:
The other thing you did is anybody who drives a motor vehicle in Wisconsin impliedly consents to a blood or breath draw after they're arrested. And you were arrested, and you disregarded that, and you will be punished for that today. You don't have the right not to consent. And that's going to result in a higher sentence for you.
Dalton was sentenced to 180 days in jail on the OWI count and 90 days on the OAR count, to be served consecutively.
¶22 Dalton filed a postconviction motion seeking to withdraw his no contest pleas. He asserted that his counsel was ineffective for failing to file a motion to suppress the evidence resulting from the warrantless blood draw. In the event his ineffective assistance of counsel claim proved unsuccessful, he alternatively sought resentencing. He contended that the circuit court erroneously exercised its discretion by explicitly punishing him for exercising his constitutional right to refuse a warrantless blood draw.
¶23 The circuit court denied Dalton's motion for plea withdrawal without holding an evidentiary hearing. It concluded "that exigent circumstances justified the warrantless blood draw in this case" and that therefore "trial counsel is not ineffective for failing to file a meritless motion[.]"
¶24 Dalton's motion for resentencing was also denied. In denying the motion, the circuit court stated, "everybody knows a court may not punish a person for exercise of the constitutional right, a right to trial, right to remain silent, but there is no right to refuse, so the [c]ourt has discretion and I think [has] the responsibility to consider a refusal an aggravating factor in sentencing an offender accordingly."
¶25 Dalton appealed both the denial of his plea withdrawal motion and his motion for resentencing. During the pendency of the appeal, the United States Supreme Court decided Birchfield, --- U.S. ----, 136 S.Ct. 2160, 195 L.Ed.2d 560.
¶26 The court of appeals reversed the circuit court. See State v. Dalton, No. 2016AP6-CR, unpublished slip op., 2016 WL 3909587 (Wis. Ct. App. July 20, 2016) ( Dalton I ). It remanded the case to the *127circuit court for a Machner 5 hearing and directed the circuit court to address Dalton's claim for resentencing in light of Birchfield.
¶27 On remand, the circuit court held a Machner hearing, where Dalton's trial counsel testified. Counsel stated that prior to entering his pleas, Dalton had raised concerns about the fact that the police had taken his blood without a warrant. Counsel researched the issue and wrote a memo for her file. In discussing with Dalton whether to file a motion to suppress, counsel informed him that she "did not believe there was a basis for it, and based on reviewing the discovery in conjunction with the case law, and the facts surrounding the case, we talked about it and determined there was not a basis for suppressing the blood."
¶28 Following the Machner hearing, the circuit court again denied Dalton's motion to withdraw his pleas, concluding that exigent circumstances were present. In making this decision, it observed:
This was a complicated and fluid situation. There's potentially life-threatening injuries to the Defendant, injuries to another individual. Sounds like a chaotic night in Washington County in terms of the need for law enforcement work in a variety of contexts and relatively serious incidents. In addition to the responsibilities the deputy had here for the traffic stop, he had to secure the accident, examine the scene, talk to witnesses, help get the Defendant out of the vehicle, get him into an ambulance, arrange for transport by helicopter, and then follow him down there promptly, and had to wait for him to get [ ] medical clearance before he could have contact with him. And this happened outside of Washington County. These are highly unusual factors. These are the kind of factors that are appropriate to consider on a case-by-case basis in making a determination about whether exigent circumstances exist.
¶29 With regard to counsel's decision not to file a motion to suppress, the circuit court stated: "[counsel] considered the propriety of a motion to suppress here. She decided not to file one, because she didn't think it had legal merit. She talked to the Defendant about it before deciding." The circuit court viewed counsel's decision as "the result of an exercise of reasonable professional judgment" and determined that her assistance was "not ineffective for failing to file a meritless motion."
¶30 Further, the circuit court determined that Birchfield had no effect on its earlier sentencing decision. It found Birchfield distinguishable from this case because "Wisconsin doesn't criminalize a refusal." In the circuit court's view, "[i]ncreasing a punishment of a defendant because of his refusal is not the same as making that refusal a crime ...." Accordingly, the circuit court denied the motion for resentencing.
¶31 Dalton again appealed, renewing his arguments that he is entitled to withdraw his plea due to ineffective assistance of counsel and that he is entitled to resentencing pursuant to Birchfield. The court of appeals affirmed the circuit court, concluding that "exigent circumstances existed that justified the warrantless draw of [Dalton's] blood, and the circuit court did not err in considering Dalton's refusal to the blood draw as an aggravating factor in sentencing." State v. Dalton, No. 2016AP2483-CR, unpublished slip op., ¶ 1, 2017 WL 3078331 (Wis. Ct. App. July 19, 2017) ( Dalton II ).
*128II
¶32 This case presents Dalton's claim of ineffective assistance of counsel. For a claim of ineffective assistance of counsel to be successful, a defendant must demonstrate both that (1) counsel's representation was deficient; and (2) the deficiency was prejudicial. State v. Maloney, 2005 WI 74, ¶ 14, 281 Wis. 2d 595, 698 N.W.2d 583 (citing Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984) ). We need not address both components of the inquiry if the defendant makes an insufficient showing on one. Id.
¶33 Appellate review of an ineffective assistance of counsel claim is a mixed question of law and fact. State v. Erickson, 227 Wis. 2d 758, ¶ 21, 596 N.W.2d 749 (1999). The circuit court's findings of fact will not be disturbed unless they are clearly erroneous. Id. However, the ultimate determination of whether the attorney's performance falls below the constitutional minimum is a question of law we review independently of the determinations rendered by the circuit court and court of appeals. Id.
¶34 To demonstrate deficient performance, a defendant must show that counsel's representation fell below an objective standard of reasonableness considering all the circumstances. State v. Carter, 2010 WI 40, ¶ 22, 324 Wis. 2d 640, 782 N.W.2d 695 (citing Strickland, 466 U.S. at 688, 104 S.Ct. 2052 ). Counsel has a duty to reasonably investigate or to make a reasonable decision that renders particular investigations unnecessary. Carter, 324 Wis. 2d 640, ¶ 23, 782 N.W.2d 695.
¶35 In evaluating counsel's performance, this court is highly deferential to counsel's strategic decisions. State v. Balliette, 2011 WI 79, ¶ 26, 336 Wis. 2d 358, 805 N.W.2d 334. Counsel's performance need not be perfect, or even very good, to be constitutionally adequate. State v. Thiel, 2003 WI 111, ¶ 19, 264 Wis. 2d 571, 665 N.W.2d 305.
¶36 We are also asked to determine whether the circuit court erroneously exercised its discretion at sentencing. A circuit court's sentence is a discretionary decision. McCleary v. State, 49 Wis. 2d 263, 277, 182 N.W.2d 512 (1971). On appeal, review is limited to determining if discretion was erroneously exercised. State v. Gallion, 2004 WI 42, ¶ 17, 270 Wis. 2d 535, 678 N.W.2d 197. An exercise of discretion is erroneous if it is based on an error of fact or law. Zarder v. Humana Ins. Co., 2010 WI 35, ¶ 21, 324 Wis. 2d 325, 782 N.W.2d 682. Additionally, a circuit court erroneously exercises its sentencing discretion when it "actually relies on clearly irrelevant or improper factors." State v. Alexander, 2015 WI 6, ¶ 17, 360 Wis. 2d 292, 858 N.W.2d 662 (quoting State v. Harris, 2010 WI 79, ¶ 66, 326 Wis. 2d 685, 786 N.W.2d 409 ).
III
¶37 We begin by setting forth the principles of Fourth Amendment law that govern blood draws in OWI cases. Next we apply those principles to the facts of this case, examining Dalton's contention that his counsel was ineffective for failing to file a motion to suppress the results of the warrantless blood draw. We then turn to Dalton's request for resentencing due to the circuit court's alleged violation of Birchfield.
A
¶38 The Fourth Amendment to the United States Constitution and Article I, Section 11 of the Wisconsin Constitution protect against unreasonable searches and *129seizures.6 State v. Eason, 2001 WI 98, ¶ 16, 245 Wis. 2d 206, 629 N.W.2d 625. Warrantless searches are presumptively unreasonable unless an exception to the warrant requirement applies. State v. Tullberg, 2014 WI 134, ¶ 30, 359 Wis. 2d 421, 857 N.W.2d 120 (citations omitted).
¶39 An exception to the warrant requirement applies when there are exigent circumstances, i.e. if the need for a search is urgent and there is insufficient time to obtain a warrant. Id. There are four circumstances which, when measured against the time needed to obtain a warrant, constitute the exigent circumstances required for a warrantless search: (1) an arrest made in "hot pursuit," (2) a threat to safety of a suspect or others, (3) a risk that evidence will be destroyed, and (4) a likelihood that the suspect will flee. State v. Hughes, 2000 WI 24, ¶ 25, 233 Wis. 2d 280, 607 N.W.2d 621.
¶40 In an OWI case, the natural dissipation of alcohol in the bloodstream may present a risk that evidence will be destroyed and may therefore support a finding of exigency in a specific case. Missouri v. McNeely, 569 U.S. 141, 156, 133 S.Ct. 1552, 185 L.Ed.2d 696 (2013). "While experts can work backwards from the BAC at the time the sample was taken to determine the BAC at the time of the alleged offense, longer intervals may raise questions about the accuracy of the calculation." Id. For this reason, exigent circumstances to justify a warrantless blood draw "may arise in the regular course of law enforcement due to delays from the warrant application process." Id.
¶41 Evidentiary rules reflect the fact that blood tests decrease in accuracy as more time passes. Results of a blood test are automatically admissible to prove intoxication or demonstrate a prohibited alcohol concentration "if the sample was taken within 3 hours after the event to be proved." Wis. Stat. § 885.235(1g) (2013-14).7 After this three-hour window, the evidence "is admissible only if expert testimony establishes its probative value and may be given prima facie effect only if the effect is established by expert testimony." § 885.235(3).
¶42 Yet the dissipation of alcohol in the blood does not create an exigency per se. McNeely, 569 U.S. at 144, 133 S.Ct. 1552. Rather, "[w]hether a warrantless blood test of a drunk-driving suspect is reasonable must be determined case by case based on the totality of the circumstances." Id. at 156, 133 S.Ct. 1552.
¶43 The test for determining the existence of exigent circumstances is objective. Tullberg, 359 Wis. 2d 421, ¶ 41, 857 N.W.2d 120. Courts must determine whether the police officers under the circumstances known to them at the time reasonably believed that a delay in procuring a warrant would risk the destruction of evidence. Id. (quoting State v. Robinson, 2010 WI 80, ¶ 30, 327 Wis. 2d 302, 786 N.W.2d 463 ).
*130B
¶44 Here the totality of the circumstances amounted to, in the words of the circuit court, a "complicated and fluid situation" and a "chaotic night in Washington County." Although McNeely establishes that exigent circumstances "may arise in the regular course of law enforcement due to delays from the warrant application process[,]" 569 U.S. at 156, 133 S.Ct. 1552, the circumstances with which law enforcement officers were presented in this case went well beyond the "regular course of law enforcement."
¶45 Events on the evening in question presented the officers with many moving parts that inform our analysis. First, there were two injured people who needed urgent medical attention. A law enforcement officer "who is confronted with an accident scene[ ] should first attend to the emergency circumstances at hand." Tullberg, 359 Wis. 2d 421, ¶ 49, 857 N.W.2d 120. The officers' decision to tend to Dalton and his passenger's medical needs at the expense of requesting a warrant was certainly reasonable.
¶46 Second, there was a need to examine and secure the scene. An officer's responsibilities at an accident scene include securing evidence and ensuring the safety of those traveling on the road near and through the scene. State v. Howes, 2017 WI 18, ¶ 46, 373 Wis. 2d 468, 893 N.W.2d 812. That the safety of passersby would take precedence over applying for a warrant is, again, reasonable.
¶47 Third, it was imperative that law enforcement speak with Dalton's passenger while events were fresh in his mind. Just as alcohol dissipates in the blood, the memories of witnesses fade. Interviewing witnesses can give officers necessary information to determine whether they have probable cause for a warrant and therefore may be a necessary prerequisite to a warrant application. Accordingly, it was reasonable for Deputy Vanderheiden to drive to the hospital in Menomonee Falls to speak with the passenger before applying for a warrant for Dalton's blood.
¶48 Finally, the crash at issue here was not the only incident requiring law enforcement attention that evening. Four officers were needed to respond to an accident involving personal injury, a fleeing driver, a vehicle in the middle of the road, and downed power poles. Two others were dispatched to an auto theft. This left two deputies to patrol the entirety of Washington County, one assigned to the northern half and one to the southern half of the 432 square mile county. Given these other incidents, law enforcement's actions were certainly reasonable under the circumstances.
¶49 This court is not in the business of second-guessing law enforcement's reasonable allocation of resources in a complex and evolving situation. See U.S. v. Sokolow, 490 U.S. 1, 11, 109 S.Ct. 1581, 104 L.Ed.2d 1 (1989) (explaining that courts do not "indulge in unrealistic second-guessing" of police's "swift, on-the-spot decisions.") When presented with multifaceted and chaotic circumstances like those presented here, law enforcement needs flexibility to determine its priorities.
¶50 Dalton essentially contends that officers should have prioritized arresting him over his medical needs and the safety of the scene, not to mention the additional happenings in the county. His assertion is unpersuasive. Police serve a dual purpose at an accident scene. They are present to investigate the cause of the accident and gather evidence of wrongdoing, but they are also there as first responders to injuries. See 3 Wayne R. LaFave, Search & Seizure § 6.6 (5th ed. 2012) ("The police have complex and multiple tasks to perform in addition to identifying *131and apprehending persons committing serious criminal offenses[,]" including "aid[ing] individuals who are in danger of physical harm" and "provid[ing] other services on an emergency basis.").
¶51 The touchstone of the Fourth Amendment is reasonableness. Ohio v. Robinette, 519 U.S. 33, 39, 117 S.Ct. 417, 136 L.Ed.2d 347 (1996). Officers' prioritizing safety and medical needs over a warrant application when presented with these circumstances was reasonable.
¶52 Given the surrounding circumstances, the dissipation of alcohol in Dalton's blood and the rapidly closing three-hour window to accomplish a presumptively admissible and accurate blood draw, Deputy Stolz was presented with an exigent circumstance. Wis. Stat. § 885.235(1g). Such events gave rise to a reasonable belief that a delay in procuring a warrant would risk the destruction of evidence.8 See Tullberg, 359 Wis. 2d 421, ¶ 41, 857 N.W.2d 120.
¶53 Consequently, a motion to suppress the blood evidence would have been meritless, and the failure to file it does not constitute deficient performance.9 State v. Cummings, 199 Wis. 2d 721, 747 n.10, 546 N.W.2d 406. Because we determine that Dalton's counsel was not deficient, we need not address the prejudice prong of the analysis. State v. Breitzman, 2017 WI 100, ¶ 81, 378 Wis. 2d 431, 904 N.W.2d 93.
¶54 We therefore conclude that exigent circumstances existed, permitting police to draw Dalton's blood absent a warrant. Accordingly, his counsel was not ineffective for failing to file a meritless motion to suppress.
IV
¶55 Having determined that Dalton's counsel was not ineffective, we turn next to Dalton's contention that the circuit court erroneously exercised its discretion at sentencing. Specifically, Dalton argues that the circuit court impermissibly lengthened his sentence because he refused a warrantless blood draw, thereby violating Birchfield, --- U.S. ----, 136 S.Ct. 2160, 195 L.Ed.2d 560.
¶56 A circuit court must set forth the reasons for its sentence on the record. Wis. Stat. § 973.017(10m) ; Gallion, 270 Wis. 2d 535, ¶ 4, 678 N.W.2d 197. In crafting a sentence, circuit courts are to consider the protection of the public, the gravity of the offense, and the rehabilitative needs of the defendant. Gallion, 270 Wis. 2d 535, ¶ 44, 678 N.W.2d 197. A circuit court erroneously exercises its discretion when it bases its decision on an error of law or *132fact. Zarder, 324 Wis. 2d 325, ¶ 21, 782 N.W.2d 682.
¶57 In Birchfield, the United States Supreme Court considered whether a law making "it a crime for a motorist to refuse to be tested after being lawfully arrested for driving while impaired" violates the Fourth Amendment's proscription against unreasonable searches and seizures. 136 S.Ct. at 2166-67. The Court concluded "that motorists cannot be deemed to have consented to submit to a blood test on pain of committing a criminal offense." Id. at 2186.
¶58 Moving to the final issue in its analysis, the Birchfield court acknowledged that "prior opinions have referred approvingly to the general concept of implied-consent laws that impose civil penalties and evidentiary consequences on motorists who refuse to comply." Id. at 2185. Yet, the court emphasized that criminal penalties may not be imposed for a refusal. "It is another matter, however, for a State not only to insist upon an intrusive blood test, but also to impose criminal penalties on the refusal to submit to such a test." Id."There must be a limit to the consequences to which motorists may be deemed to have consented by virtue of a decision to drive on public roads." Id.
¶59 In sum, Birchfield dictates that criminal penalties may not be imposed for the refusal to submit to a blood test. 136 S.Ct. at 2185. A lengthier jail sentence is certainly a criminal penalty. See Doering v. WEA Ins. Grp., 193 Wis. 2d 118, 141, 532 N.W.2d 432 (1995) (referring to imprisonment as a criminal penalty); State v. Peterson, 104 Wis. 2d 616, 621, 312 N.W.2d 784 (1981) (same).
¶60 In setting forth the reasons for its sentence on the record, the circuit court stated in relevant part:
The other thing you did is anybody who drives a motor vehicle in Wisconsin impliedly consents to a blood or breath draw after they're arrested. And you were arrested, and you disregarded that, and you will be punished for that today. You don't have the right not to consent. And that's going to result in a higher sentence for you.
It was thus definitive in its intent to give Dalton a longer sentence for the sole reason that he refused to submit to a blood test. This is a violation of Birchfield.
¶61 Pursuant to the circuit court's unequivocal sentencing remarks, Dalton was criminally punished for exercising his constitutional right.10 Established case law indicates that this is impermissible. Harman v. Forssenius, 380 U.S. 528, 540, 85 S.Ct. 1177, 14 L.Ed.2d 50 (1965) ; Buckner v. State, 56 Wis. 2d 539, 550, 202 N.W.2d 406 (1972) (explaining that "[a] defendant cannot receive a harsher sentence solely because he availed himself of one of his constitutional rights."); see also Kubart v. State, 70 Wis. 2d 94, 97, 233 N.W.2d 404 (1975) ("A defendant cannot receive a harsher sentence solely because he has availed himself of the important constitutional right of trial by jury.").
¶62 The State attempts to avoid this conclusion by contending that refusal to submit to a blood test is not a stand-alone crime in Wisconsin. It also asserts that *133any increase in a sentence within the statutorily prescribed range does not morph a sentencing consideration into a criminal penalty. We find each of these contentions unconvincing.
¶63 As to the State's first argument, the fact that refusal is not a stand-alone crime does not alter our analysis.11 This is not a distinction the Birchfield Court drew. Although Birchfield states that "motorists cannot be deemed to have consented to submit to a blood test on pain of committing a criminal offense[,]" it also addresses the wider impermissibility of criminal penalties for refusal, not only criminal charges. See Birchfield, 136 S.Ct. at 2185-86.
¶64 Dalton's sentencing transcript indicates that the circuit court's comments were straightforward and unequivocal. The circuit court plainly signaled that it was giving Dalton a harsher penalty because of his refusal.12 The fact that Dalton could not be charged with a separate crime does not change the fact that he explicitly received a stiffer sentence based solely on his refusal to submit to an evidentiary blood test.
¶65 Second, the State asserts that refusal is a legitimate sentencing consideration because it reflects on the character of the defendant, and it may be taken into account as long as it does not push the punishment above the statutorily allowed maximum for OWI. Accepting the State's argument would render the limitations of Buckner and Kubart a nullity. Taken to its logical extreme, the State's argument would allow a circuit court to increase a sentence because a defendant exercised the right to a jury trial, did not consent to a search of his home, or exercised his right to remain silent, as long as the sentence is within the statutory range. Contrarily, our case law indicates that a defendant may not be punished in this manner.
¶66 The Birchfield court recognized that "[t]here must be a limit to the consequences to which motorists may be deemed to have consented by virtue of a decision to drive on public roads." 136 S.Ct. at 2185. The limitation it established directs: no criminal penalties may be imposed for refusal. Here the record demonstrates that Dalton was criminally penalized for his refusal to submit to a blood draw. By explicitly punishing Dalton for refusal, the circuit court violated Birchfield. In denying Dalton's postconviction motion after remand, it made an error of law by misapplying Birchfield. Such error constitutes an erroneous exercise of discretion.
¶67 We therefore conclude that the circuit court violated Birchfield by explicitly subjecting Dalton to a more severe criminal penalty because he refused to provide a blood sample absent a warrant. Consequently, Dalton is entitled to resentencing.
V
¶68 In sum, we conclude that exigent circumstances existed, permitting police to draw Dalton's blood absent a warrant. Accordingly, his counsel was not ineffective *134for failing to file a meritless motion to suppress. We further conclude that the circuit court violated Birchfield by explicitly subjecting Dalton to a more severe criminal penalty because he refused to provide a blood sample absent a warrant. Consequently, Dalton is entitled to resentencing.
¶69 Accordingly, we reverse the decision of the court of appeals, and remand to the circuit court for resentencing.
By the Court. -The decision of the court of appeals is reversed, and the cause remanded to the circuit court.
PATIENCE DRAKE ROGGENSACK, C.J. (dissenting).
¶70 The circuit court's sentencing of Patrick H. Dalton does not conflict with Birchfield v. North Dakota, 579 U.S. ----, 136 S.Ct. 2160, 195 L.Ed.2d 560 (2016) and is well within the circuit court's sentencing discretion. Because the majority opinion misunderstands the directive of Birchfield and expands the statutory opportunity to withdraw consent pursuant to Wis. Stat. § 343.305(4) into a constitutional right to refuse a blood draw contrary to South Dakota v. Neville, 459 U.S. 553, 103 S.Ct. 916, 74 L.Ed.2d 748 (1983), I respectfully dissent.
I. BACKGROUND
¶71 The majority opinion ably narrates the circumstances surrounding Dalton's arrest and conviction for Operating While Intoxicated (OWI), second offense, and Operating After Revocation (OAR). Therefore, I shall relate only that which is necessary to assist the reader's understanding of this dissent.
¶72 Dalton was involved in a high-speed crash in which he and his passenger were seriously injured. They were transported to two different hospitals. Dalton exhibited overt signs of intoxication and Deputy Stolz arrested him for driving while intoxicated. Deputy Stolz read Dalton the Informing the Accused form and Dalton withdrew his consent to a blood draw.
¶73 Deputy Stolz asked a nurse to draw a blood sample and she did so. Dalton had a blood alcohol level of 0.238. This is nearly three times the level of 0.08 for which Dalton could have been convicted of unlawful intoxication. Wis. Stat. §§ 340.01(46m)(a) and 346.63(1)(b).
¶74 At sentencing after Dalton's conviction for OWI, as a second offense, and conviction for OAR, the circuit court discussed the seriousness of the accident and how Dalton could have killed his friend and himself. The court commented on his level of intoxication and the foul language he used with the arresting officer, who also had assisted in securing the med-flight that Dalton needed. The court commented on Dalton's withdrawal of consent to a blood draw as additional evidence of Dalton's disregard of his obligations under the law. The majority opinion elicits no other comment by the sentencing court that it concludes was objectionable.
II. DISCUSSION
A. Standard of Review
¶75 We review whether Dalton's sentencing for an OWI conviction comes within the proscriptions of Birchfield, independent of the court of appeals and circuit court's decisions while benefitting from their discussions. State v. Brereton, 2013 WI 17, ¶ 17, 345 Wis. 2d 563, 826 N.W.2d 369. We review a circuit court's sentencing decision under the erroneous exercise of discretion standard. State v. Alexander, 2015 WI 6, ¶ 16, 360 Wis. 2d 292, 858 N.W.2d 662 ; State v. Gallion, 2004 WI 42, ¶ 17, 270 Wis. 2d 535, 678 N.W.2d 197.
*135B. Birchfield Principles
¶76 Birchfield is the latest United States Supreme Court decision in the saga of implied-consent laws. The Birchfield decision is a combination of three cases, but I will focus on Danny Birchfield's circumstances.1
¶77 Coming upon Birchfield after he drove his vehicle off a North Dakota highway, a state trooper stopped to help. Birchfield, 136 S.Ct. at 2170. It soon became apparent that Birchfield was intoxicated. Id. The trooper arrested Birchfield and informed him of his obligations under North Dakota law to agree to a blood alcohol concentration (BAC) test and that refusing to submit to a blood draw would subject him to criminal penalties.2 Id. Nevertheless, Birchfield refused. Id. He then pleaded guilty to a misdemeanor violation of the refusal statute, while contending that the Fourth Amendment prohibited criminalizing his refusal. Id. at 2170-71.
¶78 The Court explained that it granted certiorari in Birchfield and the two companion cases "in order to decide whether motorists lawfully arrested for drunk driving may be convicted of a crime or otherwise penalized for refusing to take a warrantless test measuring the alcohol in their bloodstream." Id. at 2172. The Court sharply focused on the Fourth Amendment issue. "The question, then, is whether the warrantless searches at issue here were reasonable," id. at 2173, and "how the search-incident-to-arrest doctrine applies to breath and blood tests incident to such arrests," id. at 2174.
¶79 Although the Court approved warrantless breath tests for those arrested for operating a vehicle while intoxicated, concluding they do not implicate any significant privacy concerns, id. at 2178, the Court concluded that blood draws did involve privacy concerns due to "significant bodily intrusions" required for blood draws, id. However, the Court also concluded that "requiring the police to obtain a warrant in every case would impose a substantial burden but no commensurate benefit." Id. at 2181-82. Although the Court concluded that "Birchfield was threatened with an unlawful search," because his refusal would be criminalized under North Dakota law, id. at 2186, the Court was less than clear about whether implied consent laws that impose civil penalties and evidentiary consequences on motorists who refuse required a warrant for a blood draw.
¶80 The Court seemed to approve blood draws "based on the driver's legally implied consent to submit to them." Id. at 2185. The Court confirmed its approval of "implied-consent laws that impose civil penalties and evidentiary consequences on motorists who refuse to comply." Id. Therefore, refusal to comply with an implied-consent law's consent to submit to a blood draw could be sanctioned administratively. "Petitioners do not question the constitutionality of those laws, and nothing we say here should be read to cast doubt on them." Id. (emphasis added).
¶81 However, the Court concluded that imposing criminal penalties for withdrawing consent to a blood draw went too far. "It is another matter, however, for a State not only to insist upon an intrusive blood *136test, but also to impose criminal penalties on the refusal to submit to such a test." Id. The Court then concluded that "motorists cannot be deemed to have consented to submit to a blood test on pain of committing a criminal offense." Id. at 2186.
¶82 Under the circumstances Dalton presents in the case before us, his refusal was not criminalized. Wis. Stat. § 343.305(4). Rather, the misdemeanor of which Dalton was convicted was a consequence of his withdrawing consent that resulted in a revocation under § 343.305(10), which then counted as his second OWI conviction pursuant to Wis. Stat. § 346.65(2)(am)2. Wis. Stat. § 343.307(1)(f). If his refusal were counted as his first OWI, there would have been no criminal penalties. § 346.65(2)(am)1.
¶83 Stated otherwise, the criminal sanction was due to Dalton's repetitive driving while intoxicated. Moving to criminal penalties because of repetitive OWI's was noted without objection in Birchfield. Id. at 2169 ("the State imposes increased mandatory minimum sentences for drunk-driving recidivists.").
¶84 The majority opinion aligns Birchfield with what it asserts is Dalton's "more severe criminal penalty because he refused to provide a blood sample absent a warrant."3 The "penalty" to which the majority refers was its own evaluation of the discretionary sentencing of the circuit court for Dalton's second OWI and first OAR convictions. Birchfield has nothing to do with discretionary sentencing decisions. It turns entirely on a mandatory criminal misdemeanor charge that North Dakota imposed for refusing to submit to a blood draw. Id. at 2170-71.
¶85 The majority opinion is expanding Birchfield into discretionary sentencing decisions for a repetitive OWI conviction that required a criminal penalty. See Wis. Stat. § 346.65(2)(am)2. Birchfield's expansion is apparent from the majority opinion's definition of "criminal penalty": "A lengthier jail sentence is certainly a criminal penalty."4 That is not how "criminal penalty" was defined in Birchfield. There, the comparison was between administrative penalties for refusal and statutorily required criminal penalties for refusal. Administrative penalties for withdrawing consent were permissible and criminal penalties were not. Id. at 2186.
¶86 In the case before us, the majority opinion misleads the reader because it does not explain that Dalton did not receive a criminal penalty for refusing to submit to a blood draw. Rather, he received a criminal penalty because he had committed a second OWI. Wis. Stat. §§ 343.305(10)(b)1. and 343.307(2)(f).
¶87 The majority opinion doubles down on its erroneous conclusion of law by asserting "Dalton was criminally punished for exercising his constitutional right."5 First, the majority opinion contradicts the United States Supreme Court which has held, Dalton had no constitutional right to withdraw his consent that he gave when he drove his vehicle on Wisconsin highways after drinking to the point of intoxication. Neville, 459 U.S. at 560 n.10 & 565, 103 S.Ct. 916 (explaining that "a person suspected of drunk driving has no constitutional right to refuse to take a blood-alcohol test" and that the person's "right to refuse the blood-alcohol test [ ] is simply a matter of grace bestowed by the South Dakota legislature."); see also Birchfield, 136 S.Ct. at 2186 ("the Fourth Amendment *137did not require officers to obtain a warrant prior to demanding the [breath] test, and Bernard had no right to refuse it.").
¶88 Second, the cases cited by the majority do not provide support for the contention that Dalton had a constitutional right to refuse a blood test as the majority contends. To the contrary, the cited cases have nothing to do with implied-consent laws. Harman v. Forssenius, 380 U.S. 528, 85 S.Ct. 1177, 14 L.Ed.2d 50 (1965) involved restrictions on the constitutional right to vote through the use of poll taxes. Buckner v. State, 56 Wis. 2d 539, 202 N.W.2d 406 (1972) involved an offhand court comment at sentencing that Buckner contended invaded his right to remain silent. Kubart v. State, 70 Wis. 2d 94, 233 N.W.2d 404 (1975) involved twelve separate counts of burglary, only one of which was tried to a jury. The defendant contended that the eight year sentence was harsh and an erroneous exercise of discretion based on his going to trial on one of the counts. Once again the majority opinion tries to invoke Birchfield for purely sentencing decisions. Birchfield has nothing to do with a circuit court's sentencing discretion.
¶89 Also of concern is that the majority opinion could be read to conclude that Birchfield prohibits the misdemeanor penalty that Wis. Stat. § 346.65(2)(am)2. requires due to Dalton's revocation for refusing to take a requested test counting as a second OWI. In the future, recidivists may withdraw consent for all tests for intoxication if their refusals cannot lead to criminal penalties due to OWI recidivism that would have been imposed upon proof of intoxication from actual blood, breath or urine tests. See Wis. Stat. §§ 343.305(10) ; 343.307(1)(f) and 346.65(2)(am)2-7.
¶90 The United States Supreme Court should consider granting review herein to explain the Fourth Amendment parameters of Birchfield when state law penalties for withdrawing consent are civil and evidentiary and criminal penalties occur for recidivism. In addition, because the majority opinion chooses to disregard Neville's explicit statements that a person's refusal to permit a blood draw after being arrested for OWI is a matter of legislative grace not one of constitutional right, proof possible at OWI trials may be compromised by the exercise of this new Fourth Amendment right. These issues need attention and can receive none further in Wisconsin courts.
C. Sentencing
¶91 Sentencing is a discretionary decision of the circuit court. Gallion, 270 Wis. 2d 535, ¶ 17, 678 N.W.2d 197. A circuit court's exercise of discretion is afforded "a strong presumption of reasonability" because the circuit court is able to view the demeanor of the defendant and assess competing sentencing interests. Id., ¶ 18.
¶92 The focus of a sentencing court's consideration should be the gravity of the offense, the character and rehabilitative needs of the offender and the need for public protection. State v. Sarabia, 118 Wis. 2d 655, 673, 348 N.W.2d 527 (1984). A sentencing court properly exercises its discretion when it relies on controlling law and sets out reasoning that supports its sentencing. McCleary v. State, 49 Wis. 2d 263, 281, 182 N.W.2d 512 (1971). When a circuit court actually relies on improper factors, it erroneously exercises its discretion. Alexander, 360 Wis. 2d 292, ¶ 17, 858 N.W.2d 662.
¶93 In Dalton's sentencing, the circuit court was concerned with Dalton's repeated lack of respect for the law. The court noted that this was Dalton's second OWI and his BAC of 0.238 is so far above the legal limit that it evidences a complete disregard of his obligation to refrain from consuming significant alcohol before driving.
*138Dalton was operating after revocation when he incurred this second OWI offense, and he drove recklessly, at close to 100 miles per hour, causing severe injury to his passenger and himself.
¶94 Dalton objects to the circuit court's reference to his withdrawal of consent to submit to a blood draw as sufficient reason to remand for resentencing. The majority opinion agrees with Dalton.6 However, that one comment is insufficient to show that the circuit court erroneously exercised its sentencing discretion.
¶95 The court made a record of its concerns for Dalton's lack of respect for the law, and failing to authorize a blood draw was just one such incident. The court was concerned with Dalton's level of intoxication, 0.238. Wisconsin Stat. § 346.65(2m)(a) guides the effect of BAC level in sentencing. It provides:
In imposing a sentence under sub. (2) for a violation of s. 346.63(1)(am) or (b) or (5)... the court shall review the record and consider the aggravating and mitigating factors in the matter. If the amount of alcohol in a person's blood ... is known, the court shall consider that amount as a factor in sentencing.
¶96 Dalton's BAC level supports the circuit court's sentence as does his reckless driving and his driving after revocation. All bear on Dalton's character and demonstrate that it will not be easy to get him to turn his conduct around. The majority opinion takes the circuit court's singular statement about Dalton's refusal out of context. Read within the court's full sentencing discussion, it was just one of many factors that showed Dalton's complete disregard of the law, which is indicative of his character. The circuit court did not erroneously exercise its discretion. State v. Salas Gayton, 2016 WI 58, ¶¶ 3, 15, 370 Wis. 2d 264, 882 N.W.2d 459 (concluding that the circuit court's comments on Mr. Gayton's status as an illegal alien did not demonstrate reliance on an improper factor at sentencing).
III. CONCLUSION
¶97 The circuit court's sentencing of Dalton does not conflict with Birchfield and is well within the circuit court's sentencing discretion. Because the majority opinion misunderstands the directive of Birchfield and expands the statutory opportunity to withdraw consent pursuant to Wis. Stat. § 343.305(4) into a constitutional right to refuse a blood draw, I respectfully dissent.
¶98 I am authorized to state that Justice MICHAEL J. GABLEMAN joins this dissent.
