Plaintiff's appeal.
Plaintiff's evidence tends to show:
About 9:20 p. m. on 10 October 1953 he was driving his automobile behind two automobiles ahead of him in an easterly direction and on his right side of the highway on the bypass of Highway #158 north of the town of Henderson. His speed was 45 to 50 miles an hour. The weather was clear. He was meeting two automobiles traveling in a westerly direction on the highway. The automobile behind the first automobile he was meeting started to overtake and pass the automobile ahead of it, came across the white line in the center of the highway into plaintiff's lane of traffic, and crashed headon into plaintiff's automobile. Plaintiff was knocked unconscious in the collision, and remained in such condition two days. His wife and another woman were passengers in his automobile and were also injured. After the collision plaintiff's automobile was on his right side of the road, and a Mercury automobile that collided with it was four to six inches across the center line in the road to its left and in plaintiff's lane of traffic. The front parts of the automobiles were together. Immediately after the collision defendant Robinson was partially under the steering wheel of the Mercury, leaning to the right with her head dropped over as if dead. Defendant McGhee, the owner of the Mercury, was sitting on the front seat to her right with his head bleeding and partially unconscious. Defendant Robinson's husband and defendant McGhee's wife were slumped down in the back seat and on the floor. A day or two after the collision an officer asked defendant McGhee who was driving the Mercury at the time of the collision, and he said, "Who was on the front seat with me?"
D. M. Pendleton, a police officer of the town of Henderson, went to the scene of the collision in a brief time after it occurred to make an investigation. When he arrived about 9:15 p. m., according to his testimony, the automobiles were head-on against each other on the highway. He testified in detail as to the position of the automobiles on the highway, as to skidmarks and debris on the *611 highway, and as to the condition of the Mercury. Two or three days after the collision Pendleton had a conversation with defendant Robinson in a room in a hospital in Henderson. We summarize its substance, except when quoted: He told her he was an officer investigating the collision and wanted some information to complete his investigation. She said she could not tell him anything because she had been told not to tell anything. He asked her who was driving the Mercury, and she replied she didn't know, defendant Harold McGhee and she were in the front seat, and his wife and her husband were on the back seat; they had had a few drinks at her home and were en route to a dance at Creedmoor. Pendleton was then cross-examined by a defense counsel, who elicited from him testimony to the effect defendant Robinson told him she could not tell who was driving the Mercury, she was not driving, and that "she did not have an operator's license and did not know how to drive." (Defendant Robinson later testifying in her behalf said: "I had an operator's license at that time and had been driving an automobile ever since I was sixteen years of age. I did not have a conversation with Mr. Pendleton about my driver's license.") Pendleton then testified: "I signed that paper before some officer and swore to it." Defendant's counsel asked Pendleton to read this paper to the jury, which was identified as Defendant's Exhibit H. Plaintiff objected to the reading of the paper to the jury, was overruled, and excepted. The paper read to the jury was a warrant sworn out in the Recorder's Court of Vance County by Pendleton on 12 October 1953 charging defendant Harold McGhee on 10 October 1953 with unlawfully operating a motor vehicle on a public highway in a careless and reckless manner and damaging the automobile of G. W. McGinnis, and with feloniously assaulting G. W. McGinnis and others with a deadly weapon, to-wit, an automobile.
Plaintiff assigns as error the admission of this warrant in evidence. Defendant Robinson contends that the admission in evidence of this warrant was proper on two grounds: First. To impeach the testimony of Pendleton because he had made a prior inconsistent statement in the warrant. And Second. That it corroborated defendant's evidence later given that McGhee was driving the Mercury.
All the evidence shows Pendleton of his own knowledge did not know who was driving the Mercury. This was a disputed crucial question in the case. The sworn statement of Pendleton in the warrant that McGhee was driving the Mercury was the statement of a guess, or opinion, or conclusion resulting from his investigation which he would not have been permitted to state as a witness, and which would have been a clear invasion of the province of the jury, if he had been permitted to state it. Prior inconsistent statements of a witness are admissible for the purpose of attacking his credibility as a witness. State v. Cope, 240 N.C. 244, 81 S.E.2d 773; 98 C.J.S. Witnesses § 573. However, when the warrant here was introduced in evidence, Pendleton had not testified as to who was driving the Mercury, and the statement in the warrant of his guess, or opinion, or conclusion as to who was driving the Mercury was not inconsistent with, and did not contradict, anything he had previously testified to.
But defendant Robinson contends in her brief that when plaintiff's counsel re-examined Pendleton after the warrant was read in "evidence in respect to the circumstances under which he swore out the warrant, Pendleton testified that as a result of his investigation he found out defendant McGhee was not the driver of the Mercury, and if the admission of the warrant was error at the time it was admitted, it was cured as a result of Pendleton's testimony on re-direct examination. This contention is untenable. It is to be noted that the defendant objected to the introduction of this evidence given by Pendleton on re-examination, and then moved that it be stricken, which was denied.
Jones v. Bailey, 246 N.C. 599, 99 S.E.2d 768, was an action for damages arising from *612 an automobile collision. Plaintiff, over defendant's objection, was permitted to testify that after the accident he heard an officer, in response to an inquiry by defendant, tell her she did not have the right of way. This Court held the evidence was inadmissible as hearsay, and also as a declaration of an opinion or conclusion, which the officer could not have given in evidence. Later defendant went on the stand and denied she made an inquiry of the officer as to whether or not she had the right of way, and the officer testified he had no recollection of saying anything at the hospital to defendant. Plaintiff contended this testimony made plaintiff's testimony competent for the purpose of contradicting or impeaching the testimony of defendant and her witness, citing Hopkins v. Colonial Stores, 224 N.C. 137, 29 S.E.2d 455. The Court in awarding a new trial said:
"We do not concur in this view. Moreover, any statement in the opinion of Hopkins v. Colonial Stores, supra, that may be inferred to be in conflict with this opinion, on this particular point, is disapproved. It is the well established rule with us that when incompetent evidence is admitted over objection, but the same evidence has theretofore or thereafter been admitted without objection, the benefit of the objection is ordinarily lost, but as stated by Brogden, J., in Shelton v. Southern R. Co., 193 N.C. 670, 139 S.E. 232, 235: `The rule does not mean that the adverse party may not, on cross-examination explain the evidence or destroy its probative value, or even contradict [it] with other evidence, upon peril of losing the benefit of his exception.' State v. Godwin, 224 N.C. 846, 32 S.E.2d 609; State v. Tew, 234 N.C. 612, 68 S.E.2d 291."
Defendant Robinson in her brief has favored us with no citation of authority that the warrant introduced in evidence by defendants for the purpose of impeaching the officer Pendleton on the ground of a prior inconsistent statement is competent to corroborate defendants' evidence later given that defendant McGhee was driving the Mercury. "In no aspect of the law of evidence can contradictory evidence be used as corroborating, strengthening, or confirming evidence." State v. Lassiter, 191 N.C. 210, 131 S.E. 577. Certainly, Pendleton's guess, or opinion, or conclusion derived from his investigation that Harold McGhee was driving the Mercury, as set forth in the warrant, is incompetent, and cannot be used to corroborate defendants' evidence that McGhee was driving the Mercury.
The reading of the warrant in evidence was prejudicial error. Later when defendants were introducing evidence, they were permitted by the court over plaintiff's objection and exception to introduce this warrant in evidence. Plaintiff assigns this as error. This assignment of error is good.
Plaintiff assigns as error the introduction in evidence, over his objection and exception, of an indictment found by the grand jury at the September 1954 Term of the superior court of Vance County charging defendant Harold McGhee on 10 October 1953 with feloniously assaulting Catherine Robinson with a deadly weapon, to-wit, an automobile. This assignment of error is good. Defendant Robinson has favored us with no citation of authority showing how this indictment impeaches the testimony of the witness Pendleton. We cannot conceive of how it does.
For prejudicial error in the admission of incompetent evidence, plaintiff is entitled to a new trial, and it is so ordered.
New trial.
In 252 N.C. 574, 114 S.E.2d 365, will be found a case of plaintiff's wife against these same defendants, wherein she sought to recover damages for personal injuries growing out of the collision here. In that case, on defendants' appeal, a new trial was ordered for error in the charge.


*613 DEFENDANT ROBINSON'S APPEAL
Defendant Robinson assigns as error the court's allowing, at the close of all the evidence, plaintiff's motion for a judgment of compulsory nonsuit of her counterclaim and entering a judgment to that effect.
Plaintiff's evidence not in conflict with defendants' evidence and defendants' evidence, when considered in the light most favorable to defendant Robinson, tends to show:
About 9:15 p. m. on 10 October 1953 she was riding as a passenger on the front seat of a Mercury automobile owned and driven by Harold McGhee and traveling in a westerly direction on the Henderson bypass of Highway #158. Immediately preceding the McGhee automobile was an automobile occupied by a Mr. and Mrs. Nelson Boyd. McGhee pulled into his left (south) lane of traffic in an attempt to overtake and pass the Boyd automobile. Seeing an automobile approaching and meeting him driven by plaintiff, he pulled back into his right (north) lane of traffic. At this time the plaintiff McGinnis drove his 1949 Ford automobile into his left (north) lane of traffic colliding head-on with the McGhee automobile which was on its right of the center line on the highway. In the collision defendant Robinson sustained severe injuries.
G.S. § 20-148 provides: "Drivers of vehicles proceeding in opposite directions shall pass each other to the right, each giving to the other at least one-half of the main-traveled portion of the roadway as nearly as possible." The standard of care fixed for a motorist in this statute by the Legislature is absolute. Bondurant v. Mastin, 252 N.C. 190, 113 S.E.2d 292. A violation of this statute is negligence per se, and if it is the proximate cause of injury, it is actionable. Wallace v. Longest, 226 N.C. 161, 37 S.E.2d 112.
After a careful examination of defendants' evidence and the evidence of plaintiff not in conflict with it, we are of opinion, and so hold, that the trial court improvidently nonsuited defendant Robinson's counterclaim for personal injuries. The judgment of compulsory nonsuit of her counterclaim is
Reversed.
