¶ 1 Plaintiff, Amy Reeves, appeals a trial court Journal Entry of Judgment sustaining the Motion to Dismiss of defendant, City of Durant. This appeal proceeds under the accelerated docket pursuant to Oklahoma Supreme Court Rule 1.36, 12 O.S. Supp. 2017 ch. 15, app. 1. After review of the record on appeal and applicable law, this Court affirms.
BACKGROUND
¶ 2 On November 23, 2014, Plaintiff was injured when she was struck by a vehicle driven by Jason Schaming while crossing a street in Durant, Oklahoma. Plaintiff alleges inadequate street lighting at the intersection caused the accident. Plaintiff claims Mr. Schaming was unable to see Plaintiff crossing the street because of the inadequate street lighting and could not avoid the collision.
¶ 3 Plaintiff filed a First Amended Petition1 on December 29, 2016, alleging a cause of action for negligence against defendants, City of Durant and Oklahoma Gas and Electric Company (OG&E), for failure to keep the streetlight lit. Plaintiff alleged "the accident was caused in whole or in part by inadequate lighting due at the intersection." Plaintiff further alleged Defendant had a duty to install and maintain street lighting and once it undertook this duty, it had to do so in a manner that complied with industry standards for lighting.
¶ 4 Defendant City of Durant filed a Motion to Dismiss pursuant to 12 O.S. 2011 § 2012(B)(6).2 Defendant argued it had "no duty to install or maintain streetlights" and, therefore, Plaintiff could not establish a negligence claim. In the alternative, Defendant argued the Oklahoma Supreme Court in Ochoa v. Taylor , 1981 OK 120, 635 P.2d 604, held that the installation and maintenance of streetlights is a discretionary act and a city *142is exempt from liability under the GTCA, specifically 51 O.S. Supp. 2017 § 155(5).
¶ 5 In response, Plaintiff argued Defendant is not exempt from liability under the discretionary exemption of the GTCA because the duty to maintain streetlights that have already been installed is an operational function, not a discretionary one. Plaintiff further alleged that once Defendant had notice of the defective streetlight, it had a duty to fix the defective streetlight.
¶ 6 On September 27, 2017, Plaintiff filed a Motion to Certify Order of Dismissal for Immediate Appeal. In response, Defendant asked the trial court to deny Plaintiff's request to certify because all of Plaintiff's claims against the defendants arise out of the same transaction or occurrence. In addition, Defendant alleged Plaintiff had not shown the second element of certification, "no just reason for delay."
¶ 7 The trial court entered a Journal Entry of Judgment on January 19, 2018, sustaining Defendant's Motion to Dismiss and overruling OG&E's Special Appearance and Motion to Dismiss. The trial court also found "there is no just reason for delay, and this Journal Entry shall constitute a final judgment, decree or order as to the City of Durant" per 12 O.S.2011 § 994.
¶ 8 Plaintiff appeals.
STANDARD OF REVIEW
¶ 9 This Court reviews a trial court's order granting a motion to dismiss de novo . Wilson v. State ex rel. State Election Bd., 2012 OK 2, ¶ 4, 270 P.3d 155, 157. In a traditional motion to dismiss, the trial court "must take as true all of the challenged pleading's allegations together with all reasonable inferences which may be drawn from them." Tuffy's Inc. v. City of Oklahoma City , 2009 OK 4, ¶ 6, 212 P.3d 1158, 1162. Motions to dismiss are generally disfavored. Id . at 1163. "The purpose of a motion to dismiss is to test the law that governs the claim (in litigation), not the underlying facts." May v. Mid-Century Ins. Co. , 2006 OK 100, ¶ 10, 151 P.3d 132, 136 (footnote omitted).
ANALYSIS
¶ 10 First, this Court notes Defendant argues the trial court erred in certifying the order as a final order and one ripe for immediate appeal. However, Defendant did not appeal this issue and this Court will, therefore, not address it.
¶ 11 On appeal, Plaintiff argues the trial court erred in finding maintenance of a streetlight is a discretionary function, and not an operational or ministerial one, and that Defendant was exempt from liability under the GTCA. Plaintiff also argues the trial court erred in holding that Defendant did not have a duty to maintain the streetlight.
¶ 12 Subject only to the GTCA's specific limitations and exceptions, the GTCA waives the immunity of governmental entities for torts. Tuffy's, Inc. v. City of Oklahoma City , 2009 OK 4 ¶ 7, 212 P.3d at 1163. These exemptions are narrowly construed. Nguyen v. State of Oklahoma , 1990 OK 21, ¶ 4, 788 P.2d 962, 964. Defendant maintains that it falls under the discretionary function exemption from liability provided in 51 O.S. Supp. 2017 § 155(5) because installation and maintenance of the streetlights is a discretionary function. Plaintiff claims Defendant is not immune from liability because maintenance of the streetlight is an operational or ministerial function.
¶ 13 "Whether an act is discretionary or ministerial for purposes of application of the [GTCA] is a legal issue." Walker v. City of Moore , 1992 OK 73, ¶ 13, 837 P.2d 876, 879. "[D]iscretionary immunity must be narrowly construed." Robinson v. City of Bartlesville Bd. of Educ. , 1985 OK 39, ¶ 11, 700 P.2d 1013, 1016.
¶ 14 Section 155(5) provides that a governmental entity will not be liable for a loss or claim resulting from "[p]erformance of or the failure to exercise or perform any act or service which is in the discretion of the state or political subdivision or its employees." This specific exemption is referred to as the discretionary function exemption.
¶ 15 Defendant relies on Ochoa v. Taylor , 1981 OK 120, 635 P.2d 604, to support its *143argument that it is exempt from liability under the GTCA.
¶ 16 The Oklahoma Supreme Court in Ochoa decided the issues before this Court - ( (1) whether the installation and maintenance of street or area lighting is a discretionary act or a ministerial one; and (2) whether a municipality has a duty to install and/or maintain streetlights). In Ochoa , the Oklahoma Supreme Court held "that the installation and maintenance of street or area lighting is a discretionary act or service of a political subdivision and therefore exempt from liability under 51 O.S. Supp. 1979 § 155(5)." Ochoa , 1981 OK 120 ¶ 15, 635 P.2d at 608. The Oklahoma Supreme Court further held the City in Ochoa "owed no common law or statutory duty to install and maintain street lighting." Ochoa , 1981 OK 120 ¶ 10, 635 P.2d at 607.
¶ 17 This Court is bound by the holding in Ochoa . Wimberly v. Buford , 1983 OK 25, 660 P.2d 1050 ; see also Bays Exploration, Inc. v. Jones , 2010 OK CIV APP 28, ¶ 14, 230 P.3d 907, 910 ("It is axiomatic the Court of Civil Appeals cannot overrule an opinion of the Oklahoma Supreme Court and we are thus bound by its previous decisions.") Although the Supreme Court has focused its analysis in other factual situations on the dichotomy between discretionary functions and ministerial or operational functions, it has not disturbed its holdings in Ochoa that (1) the political subdivision did not have a duty to install and maintain street lighting; and (2) installation and maintenance of street or area lighting is a discretionary act, not a ministerial act.3
¶ 18 Pursuant to the Oklahoma Supreme Court's holding in Ochoa , this Court finds the City's installation and maintenance of the streetlight near the intersection involved in the accident was a discretionary function and City is thus exempt from liability under 51 O.S. Supp. 2017 § 155(5). This Court further finds City did not have a duty to maintain the streetlight. Therefore, the trial court did not err in finding Plaintiff failed to state a claim against Defendant and in sustaining Defendant's motion to dismiss.
