Plaintiff offered evidence as follows: After supper on 30 November 1956 the defendant Mrs. Grantham was driving a 1955 Dodge Station Wagon north on U. S. Highway 301. Riding as passengers were plaintiff and a Mrs. Knight. Between -the towns of Lum-berton and St. Pauls the highway crosses Big Marsh Swamp. In this area there is a bridge on the highway 78 feet long. This bridge has solid sides 78 feet long, about 5 feet high, -and 15 to 18 inches thick. It is about 20 feet wide. The highway leading up to it varies in width from 20 to 22% feet. About 500 feet south of -the south end of the bridge is a diamond-shaped sign with a yellow background and black letters bearing the words “Narrow Bridge.” The bridge abutments are striped black and yellow from -top to bottom. At the bridge the embankment on which the highway is built is 6 or 7 feet above the swamp. There is an embankment on each side of the highway leading to .the bridge from 2 to 6 or 7 feet.
The headlights on the automobile driven by Mrs. Grantham were burning. She was driving at a normal rate of speed on her side of the highway. A patrolman testified) for plaintiff the speed limit in that area was 55 miles per hour. As the automobile driven by Mrs. Grantham traveling north reached the sign south of the bridge bearing the words “Narrow Bridge,” an automobile traveling south on the highway was approaching the bridge, and zigzagging in the highway. At -this point in the highway plaintiff saw this automobile zigzagging in the highway, and asked Mrs. Grantham to stop, telling her there was something wrong with the approaching automobile. Mrs. Granth-am picked up a little speed, and drove on, saying “half the damn ■highway was hers.” As the automobile driven by Mrs. Grantham entered the bridge, with the other automobile -swaying in the bridge, the two automobiles collided. The two automobiles were destroyed, and plaintiff and Mrs. Grantham were injured.
After the collision a patrolman talked with Mrs. Grantham in a hospital in Lumberton. She told him -she was running about the speed *543limit, and saw the other automobile about 50 feet away. She said ■“something about seeing headlights swaying back and forth across the road.”
Mrs. Maude Hinnant testified she heard Mrs. Grantham tell plaintiff “not to talk so much, she might cause her to be tried for murder or manslaughter.”
Plaintiff assigns as error the exclusion as against Mrs. Grantham of the testimony of plaintiff that she “saw a car zigzagging across the road.” The defendant Gardner moved to strike out the answer on the ground that it violated G.S. 8-51, a party to a transaction excluded, when- the other party is dead. The motion was allowed, and the court instructed the jury not to consider this evidence. Plaintiff stated it was competent as to the defendant Grantham. The court refused to admit it as to the defendant Grantham, and plaintiff excepted. The defendant Grantham in her answer admitted as true allegations in plaintiff’s complaint to the effect that Gardner’s intestate permitted his automobile to wabble from one side -of the highway to the -other, and to -continue in such movements from one -side of the center line to the other as it approached the entrance of the bridge, and continued to -so operate his automobile after entering the bridge, and continued to drive from one -side -of the highway to the other and drove into the sides of the bridge, and caused it to rebound and collide with the automobile driven by Mrs. Grantham. This evidence was clearly competent as to Mrs. Grantham. Testimony which is competent as to one party should not be excluded because it is not competent against another party to the suit. In -such a case the evidence should be limited by proper instructions. S. v. Brite, 73 N.C. 26; S. v. Collins, 121 N.C. 667, 28 S.E. 520; S. v. Cobb, 164 N.C. 418, 79 S.E. 419; S. v. Kirkland, 175 N.C. 770, 94 S.E. 725; S. v. Franklin, 248 N.C. 695, 104 S.E. 2d 837; Olsen v. J. J. Jacobs Motor Co., 99 Cal. App. 423, 278 P. 1051; Illinois C. R. Co. v. Houchins, 121 Ky. 526, 89 S.W. 530, 1 L.R.A. (N.S.) 375, 123 Am. St. Rep. 205; Consolidated Ice Machine Co. v. Keifer, 134 Ill 481, 25 N.E. 799, 10 L.R.A. 696, 23 Am. St. Rep. 688; Jones on Evidence, Civil Cases, 4th Ed., Vol. 1, p. 306; 20 Am. Jur., Evidence, p. 253.
For .the reasons stated above the court erred in excluding plaintiff’s testimony in respect to what she -saw about the approaching automobile and as to what she said to Mrs. Grantham about it, and as to what Mrs. Grantham replied, as against Mrs. Grantham. Later on the court admitted some of this testimony.
The court properly excluded the testimony of Mrs. W. C. Griffin that plaintiff said in the hospital “if Thelma Sue Grantham hadi *544stopped the car, I would not be here.” The statement was merely an opinion of plaintiff. Lucas v. White, 248 N.C. 38, 102 S.E. 2d 387; Henderson v. Henderson, 239 N.C. 487, 80 S.E. 2d 383; Austin v. Overton, 222 N. C. 89, 21 S.E. 2d 887.
G.S. 20-140 required Mrs. Grantham at all times to drive the automobile with due oaution and circumspection and 'at a speed or in a manner so as not to endanger or to be likely to endanger any person or property, and G.S. 20-141 made a similar requirement that she shall operate her automobile with due regard to the width, traffic and condition of the highway, and, when special hazards exists by reason of highway conditions, speed shall be decreased as may be necessary to avoid collision with any person or vehicle on or entering the highway. Singletary v. Nixon, 239 N.C. 634,80 S.E. 2d 676; Kellogg v. Thomas, 244 N.C. 722, 94 S.E. 2d 903. By virtue of the express provisions of G.S. 20-141 the speed of an automobile may be unlawful “under the circumstances of a particular case, even though such speed is less than the definite statutory limit prescribed for the vehicle in the place where it is being driven.” Sowers v. Marley, 235 N.C. 607, 70 S.E. 2d 670. These statutes prescribe a standard of care, “and the standard fixed by the Legislature is absolute.” Aldridge v. Hasty, 240 N.C. 353, 82 S.E. 2d 331.
This Court said in Wall v. Bain, 222 N.C. 375, 23 S.E. 2d 330: “It is the duty of the driver of a motor vehicle not merely to look, but to keep an outlook in the direction of travel; and he is held to the duty of seeing what he ought to have seen.”
Regardless of statutes regulating the operation of automobiles, it was the duty of Mrs. Grantham in the operation of the automobile to exercise the care which a person of ordinary prudence would exercise under similar conditions to prevent injury to persons on the highway; -that is, it was her duty in keeping a proper lookout to see and take notice of a sign advising her that a “Narrow Bridge” was ahead, to see and take notice of an automobile meeting her zigzagging on the highway, and to drive at such a speed as to have the automobile under proper control, so as in the exercise of due care to avoid, if it could be done in the exercise of due care, collision with the approaching automobile on the highway or on the bridge. Kellogg v. Thomas, supra; Henderson v. Henderson, supra.
“The driver of an automobile who is himself observing the law (G.S. 20-148) in meeting and passing an automobile proceeding in the opposite direction has the right ordinarily to assume that the driver of the approaching automobile will also observe the rule and avoid a collision.” Morgan v. Saunders, 236 N.C. 162, 72 S.E. 2d 411. *545“But this right is not absolute. It may be qualified by the particular circumstances existing at the time.” Brown v. Products Co., Inc., 222 N.C. 626, 24 S.E. 2d 334. Mrs. Grantham had no absolute right to act on this assumption for a reasonably prudent man might reasonably have anticipated, that, acting on the ground that half the highway was his, to increase speed and drive into the entrance of a narrow bridge 78 feet long with solid sides 5 feet high, with >an automobile meeting him zigzagging in the road and entering and traveling upon the bridge, wouldi lead to a collision between the two automobiles.
Mrs. Grantham contends that she was confronted with a sudden emergency. This Court said in Ingle v. Cassady, 208 N.C. 497, 181 S.E. 562: “One who is required to act in an emergency is not held by the law to the wisest choice of conduct, but only to such choice as a person of ordinary care and prudence, similarly situated, would have made.”
It is settled law in North Carolina that there can be more than one proximate cause of injury. Moore v. Plymouth, 249 N.C. 423, 106 S.E. 2d 695; Price v. Gray, 246 N.C. 162, 97 S.E. 2d 844.
If the jury should find from the evidence that Mrs. Grantham was negligent, and such negligence continued to the actual collision of the two automobiles in which plaintiff was injured, it would constitute a proximate cause of plaintiff’s injuries. Graham v. R. R., 240 N.C. 338, 82 S.E. 2d 346. “No negligence is ‘insulated’ so long as it plays a substantial and proximate part in the injury.” Henderson v. Powell, 221 N.C. 239, 19 S.E. 2d 876.
The trae and ultimate test of Mrs. Grantham’s operation of the automobile is this: What would a reasonably prudent person have done in the light of all the surrounding facts and circumstances?
Considering the evidence in the light most favorable to plaintiff, and giving her the benefit of all legitimate inferences to be drawn therefrom, and in view of the applicable principles of law stated above, it is our opinion that the case against Mrs. Grantham should have been submitted to the jury.
