Plaintiff’s evidence tends to- show: About 5:30 p.m. on 10 May 1962 be was driving 'his automobile west on King Street in the town of Boone. He .stopped behind a truck prep-aring to make a left turn, and had hie left arm extended “with a slow or stop sign.” After he had been stopped there for approximately three or four minutes, Tommy Barnes driving Iris father’s automobile ran into the rear of his automobile. He was thrown forward, then jerked back over the .seat, and then thrown forward again. He sustained .serious injuries as a result of the -collision.
The joint answer admits that Jud Barnes was the owner of the automobile his son Tommy Barnes was driving at the time of the collision, and that it was registered in the name of Jud Barnes as owner.
Defendant Tommy B.arnes testified on cross-examination: “I was going 35 miles an hour. * * * I remember talking to the Chief of Police up there. * ® * I guess I .said that I told Mr. Thomas that I ran into the back of this car because I just didn't see it. I told him the car stopped .suddenly in front of me and I hit him. I told Mr. Thomas that.” The Mr. Thomas referred to was Hubert Thomas, Chief of Police of the town of Boone, and ,a witness for plaintiff.
The complaint alleges, inter alia, Tommy Barnes was negligent in operating the automobile without keeping a proper lookout.
Considering plaintiff’s evidence in the light most favorable to him, and the evidence of defendants favorable to- him, it was1 sufficient to carry the case to- the jury, -and -defendants’ assignment of error that the court erred in -denying their motion for compulsory nonsuit made at the close of all the evidence is overruled. Smith v. Rawlins, 253 N.C. 67, 116 S.E. 2d 184; Dunlap v. Lee, 257 N.C. 447, 126 S.E. 2d 62; G.S. 20-71.1.
Defendants assign as error the failure of the court in its charge to -apply -the law to the evidence on the substantial features of the case, in that the court failed to charge and apply the applicable statutory -law as to speed of automobiles, and failed to charge and apply -the law -as it relates to- the variant factual situations arising on the evidence given in the case.
A study -o-f the charge show® that the court gave the contentions of the parties and instructed the jury with respect to negligence and *343proximate cause according to the rule of the reasonably prudent man, with respect to' the maximum speed in a “business district,” and with respect to giving a signal when preparing to stop. But nowhere in the charge did the court instruct the jury what facts it was necessary for them to find to constitute negligence on the part of Tommy Barnes, and contributory negligence on the part of plaintiff. Nowhere in the charge did the count instruct the jury as to the circumstances under which the first issue, a>s to whether plaintiff was injured by defendants’ negligence, should be answered in the affirmative, and under what circumstances it should be answered in the negative.
“The chief purpose of a charge is to aid the jury to understand 'dearly the case, and to arrive at a correct verdict. For this reason, this Court has consistently ruled that G.S. 1-180 imposes upon the Trial Judge the positive duty of declaring and explaining the law arising on the evidence as to all the substantial features of the case. A mere declaration of the laiw in general terms and a statement of the contentions of the parties, as here, is not sufficient to meet the statutory requirement. Hawkins v. Simpson, 237 N.C. 155, 74 S.E. 2d 331, where 14 of our cases are cited. In Lewis v. Watson, 229 N.C. 20, 47 S.E. 2d 484, this Court said, quoting from Am. Jur.: ‘The statute requires the judge “to explain the law of the case, .to point out the essentials to be proved on the one .side or -the other, and to ■bring into view the relations of the particular evidence adduced to the particular issues involved.” 53 Am. Jur., Trial, section 509.’ ”
Unless the mandatory provision of G.S. 1-180 is complied with, “there can be no assurance that the verdict represents a finding by the jury under the law and on the evidence presented.” Smith v. Kappas, 219 N.C. 850, 15 S.E. 2d 375.
We can find nothing in the record to indícate that the collision here occurred in a “business district,” as -such a district is defined in G.S. 20-38 (a). The maximum speed in a “business district” is 20 miles per hour, G.S. 20-141 (b) (1); in a “residential district” 35 miles per hour, G.S. 20-141 (b) (2). There is nothing in the record to indicate that -the collision here occurred in a “residential district,” as such a district is defined in G.S. 20-38 (w)l. The court charged the maximum speed in a “business district” was 20 miles per hour, but did not charge as .to the maximum speed elsewhere. *344Under the facts here, .this charge on an abstract principle of law not «supported by any .evidence .in .the case is prejudicial error. Carswell v. Lackey, 253 N.C. 387, 117 S.E. 2d 51; Andrews v. Sprott, 249 N.C. 729, 107 S.E. 2d 560.
For errors in the charge defendants are entitled to. a new .trial, ■and it is so 'Ordered.
