Appeal as to Plaintiff Tharpe
The plaintiff's main exception and assignment of error, upon which her appeal turns, is to the judgment of nonsuit entered at the close of the plaintiff's evidence upon the motion of the defendant Swaim.
In considering a motion for judgment as of nonsuit, all of the evidence must be taken in the light most favorable to the plaintiff. Lienthall v. Glass, 2 N.C. App. 65, 162 S.E.2d 596 (1968); Champion v. Waller, 268 N.C. 426, 150 S.E.2d 783 (1966).
The plaintiff, in her complaint, alleged that her injuries were proximately caused by the negligence of the defendant, Joy Dowell Swaim, in the following respects:
"III. That on the 8th day of November, 1967, at approximately 6:30 p.m., the plaintiff was riding as a guest passenger, sitting in the right-hand side of the rear seat of the 1956 Dodge automobile owned by James Calvin Swaim. That the said automobile was sitting still on the left-hand side and shoulder of Rural Paved Road 2002 with the front of the said automobile directed in a northern direction of Rural Paved Road 2002. That on this occasion, the 1956 Dodge automobile was sitting pointed in a northern direction with the wheels on the left side of the automobile approximately four feet off the edge of the pavement and that the right wheels of the automobile were sitting approximately two feet upon the paved edge of the road. That on this same date and time the defendant, Stacy Brewer, was operating a 1965 green Chevrolet pickup in a southern direction on Rural Paved Road 2002. That when the Chevrolet pickup approached the Dodge automobile, which was parked on the edge of the road, a portion of the said Dodge was in the lane of traffic in the direction in which the pickup was traveling. The defendant, *922 Stacy Brewer, applied his brakes and when he applied his brakes the pickup skidded out of control and a violent collision occurred between the right rear of the Chevrolet pickup and the front and right side of the 1956 Dodge automobile.
* * * * * *
"VI. That the defendant, Joy Dowell Swaim, was more specifically negligent in the following respects:
* * * * * *
"D. That the defendant, Joy Dowell Swaim, was negligent in that she parked the 1956 Dodge automobile on the wrong side of the road contra to the law of the State of North Carolina with a portion of the said car situated in the lane for the southbound traffic."
In Lienthall v. Glass, supra, the Court quoted the following language from Champion v. Waller, supra:
"`Facts alleged in the complaint and admitted in the answer are conclusively established by the admission, it not being necessary to introduce such allegations in evidence. Wells v. Clayton, 236 N.C. 102, 72 S.E.2d 16; Stansbury, North Carolina Evidence, § 177. The same is true of allegations of new matter in a further answer, which new matter is favorable to the plaintiff. In passing upon a motion for judgment of nonsuit, all such allegations in the answer are taken to be true and are to be considered along with the evidence.'"
The defendant Swaim answered the complaint as follows:
"III. That the allegations contained in paragraph III of the complaint are untrue and denied, except as herein admitted. * * * That the operator of said 1956 automobile had driven said automobile onto the left-hand shoulder of said road and as far off the main traveled portion as was practical, for the purpose of discharging passengers. That said automobile was momentarily stopped, with its headlights on low beam."
The pleadings and evidence in this case would permit, but not compel, the jury to find the facts to be as follows: On 8 November 1967, at about 6:30 p.m., the plaintiff, Margaret Louise Tharpe, was riding as a guest passenger in a 1956 Dodge automobile being operated by Joy Dowell Swaim, the defendant. The defendant Swaim drove the automobile from the right-hand lane of the highway and parked it on the left-hand side of the highway with approximately two feet of the automobile remaining on the pavement. After she parked the automobile, the defendant Swaim left the headlights burning while she opened the door in order to discharge passengers. Within thirty seconds after the automobile was parked on the wrong side of the highway, the defendant Brewer approached from the opposite direction on the same road. Seeing the headlights of the Swaim automobile shining down the road, he applied his brakes forcefully causing his pickup truck to skid and collide with the Swaim vehicle. As a result of the collision, the plaintiff, who was in the rear seat of the two-door automobile, was thrown from the automobile onto the ground.
The main thrust of the defendant Swaim's contention is that the allegations in the complaint are not sufficient to bring into play G.S. § 20-161.1 which is as follows:
"Regulation of night parking on highways No person parking or leaving standing a vehicle at night on a highway or on a side road entering into a highway shall permit the bright lights of said vehicle to continue burning when such lights face oncoming traffic."
It is not necessary for the plaintiff to include the statute upon which she relies in her complaint in order to state a cause of action against the defendant. In Richardson *923 v. Richardson, 4 N.C.App. 99, 165 S.E.2d 678 (1969), this Court stated:
"In order to state a cause of action, it is not necessary to put in the complaint the statute upon which the pleader is relying. `The function of a complaint is to state in a plain and concise manner the material, essential or ultimate facts which constitute the cause of action, but not the evidence to prove them. * * * It is not necessary to plead the law. The law arises upon the facts alleged, and the court is presumed to know the law.' Moore v. W O O W, Inc., 253 N.C. 1, 116 S.E.2d 186. A complaint is to be judged by the facts alleged therein, and if the allegations are sufficient, reference to a particular statute is unnecessary. Therefore, such a reference may be regarded as surplusage."
We hold that the allegation in the complaint "[t]hat the defendant, Joy Dowell Swaim, was negligent in that she parked the 1956 Dodge automobile on the wrong side of the road contra to the law of the State of North Carolina with a portion of the said car situated in the lane for the southbound traffic", when considered with the allegations and admissions in the answer of the defendant Swaim, is sufficient to support the evidence that the defendant Swaim violated G.S. § 20-161.1. The evidence, when considered in its light most favorable to the plaintiff, is sufficient to warrant the court's submitting an issue to the jury as to the negligence of the defendant Swaim. The judgment of nonsuit as to the defendant Swaim is reversed.
The appellant Tharpe contends that the trial judge committed error in submitting the issue of the appellant's contributory negligence to the jury.
The defendant Brewer, in his second further answer and defense, pleaded that the plaintiff was contributorily negligent in that she remained in the automobile of the defendant Swaim when she, the plaintiff, knew, or by the exercise of ordinary care ought to have known, that she was in a place of danger in that the Swaim automobile was parked and left unattended in the nighttime with its lights burning bright, on the left side of the public highway facing traffic, with a portion of the automobile on the pavement, in violation of G.S. § 20-161.1.
"Contributory negligence must be pleaded and proved by the defendant. G.S. § 1-139. Moore v. Chicago Bridge & Iron Works, 183 N.C. 438, 111 S.E. 776; Ramsey v. Nash Furniture Co., 209 N.C. 165, 183 S.E. 536. To be sufficient, a plea of contributory negligence must aver a state of facts to which the law attaches negligence as a conclusion. Watson v. Farmer, 141 N.C. 452, 54 S.E. 419; Cogdell Wilmington & W. v. Railroad Co., 132 N.C. 852, p. 855, 44 S.E. 618. One relying on contributory negligence must prove facts from which the inference of contributory negligence may be drawn by men of ordinary reason. Boney v. Atlantic Coast Line R. R., 155 N.C. 95, 71 S.E. 87; Farris v. Southern R. R., 151 N.C. 483, bot. p. 489, 66 S.E. 457. Evidence which raises a mere conjecture is insufficient for the jury. White v. Suffolk & C. R. R., 121 N.C. 484, 27 S.E. 1002." Bruce v. O'Neal Flying Service, 234 N.C. 79, 66 S.E.2d 312 (1951).
All of the evidence tends to show that the plaintiff was riding as a passenger in the rear seat of a two-door automobile, and that said automobile had been parked for only thirty seconds prior to the time the defendant Brewer's automobile was seen approaching from the opposite direction.
Considering all of the evidence, we hold that it was error for the court to submit an issue of contributory negligence to the jury.

Appeal as to Defendant Brewer
The defendant assigns as error the failure of the trial judge to instruct the jury *924 with regard to the doctrine of sudden emergency.
In North Carolina negligence is defined as "the failure to exercise that degree of care that an ordinarily prudent person would exercise under the same or similar circumstances and when charged with like duty." Williamson v. Clay, 243 N.C. 337, 90 S.E.2d 727 (1956). The defendant Brewer's evidence regarding the events which occurred on the night of 8 November 1967 was as follows: Sometime after dark on the night of the collision, Brewer was driving his Chevrolet pickup truck south on Rural Paved Road 2002 and as he neared the crest of the hill about 200 feet from the scene of the accident someone backed out into the highway in front of him. He reduced his speed and the person pulled back into the driveway and let him go by on the highway. Immediately after this he went over the crest of the hill and saw the lights which were shining from the Swaim vehicle. The lights blinded him and when he realized that the other vehicle was in his lane of traffic, Brewer turned his truck to the left and applied his brakes in an attempt to avoid the collision which followed.
The evidence shows that the defendant Brewer was faced with a sudden emergency. In the face of an emergency, a person is not held to the wisest choice of conduct, but only to such choice as a person of ordinary care and prudence would have made in similar circumstances. Williams v. Boulerice, 268 N.C. 62, 149 S.E.2d 590 (1966).
The North Carolina Supreme Court, in Williamson v. Clay, supra, spoke to the identical question involved in the present case. There, in discussing the duty of the trial judge to charge the jury with regard to the doctrine of sudden emergency, the Court stated:
"Even in the absence of request for special instructions, a failure to charge the law on the substantive features of the case arising on the evidence is prejudicial error. G.S. § 1-180; Barnes v. Caulbourne, 240 N.C. 721, 83 S.E.2d 898, and cases cited. In this case, since defendant relied in large measure upon what he contended were circumstances of acute emergency, the failure to comply with G.S. § 1-180 by applying the applicable legal principles to defendant's evidence in regard thereto must be regarded as prejudicial. Hence, defendant's assignment of error relating to this feature of the charge is sustained and a new trial awarded."
The appellant Brewer's additional assignments of error have been duly considered in the appellant Tharpe's appeal. For errors committed, we hold there must be a new trial.
New trial.
