This is a negligence action brought by the plaintiff administrator seeking damages for the death of his decedent resulting from a collision on the New Jersey Turnpike between an automobile operated by the decedent and a tractor-trailer truck *309 owned by the defendant and operated by its agent, servant and employee. The parties have stipulated that the issue of liability is governed by Connecticut common law. The jury found the issues for the defendant, and, on the refusal of the trial court to set aside the verdict, the plaintiff has appealed to this court from the judgment rendered.
The plaintiff assigns error in the charge of the trial court. The correctness of the charge is determined by the claims of proof of the parties. Practice Book § 635;
Moonan
v.
Clark Wellpoint Corporation,
The plaintiff assigns error in the refusal of the trial court to charge on the doctrine of emergency in accordance with his request. In its instructions to the jury, the court made no reference to the emergency doctrine. On an examination of the plaintiff’s request to charge, it is apparent that portions of it would have improperly invaded the provvince of the jury by requiring them, rather than permitting them, to find that an emergency existed if they found that the truck was tailgating the decedent’s car so closely as to cause, in a reasonably prudent driver, a fear for his own safety. The trial court was not required to follow such a request.

Moonan
v.
Clark Wellpoint Corporation,
supra, 186. Another portion of the request to charge properly defined an emergency. “Generally, error cannot properly be predicated upon a refusal of the court to charge as requested in a certain paragraph, although it contains correct propositions of law, if it also includes others which are not, or contains objectionable matter which cannot properly be charged.”
Urbansky
v.
Kutinsky,
The conduct of the plaintiff’s decedent in the operation of his car was called into question by the special defense of contributory negligence. Although the application of the emergency doctrine does not alter the standard of care to be exercised, it is a factor to be considered in the evaluation of the decedent’s conduct. In an emergency not due to his own negligence, one is not relieved of all obligations to exercise care but is required to exercise the care of an ordinarily prudent person acting in such an emergency.
Degnan
v.
Olson,
To require the giving of an instruction on the doctrine of sudden emergency in the instant case, there must be an adequate basis in the claims of proof to satisfy each of the following elements: (1) An emergency actually existed; (2) the perilous situation was not created by the plaintiff’s decedent; and (3) the decedent, confronted with the emergency, chose the course of action which would or might have been taken by a person of reasonable prudence in the same or a similar situation.
Miller
v.
Porter,
*313
The finding indicates that the decedent was followed so closely by the defendant’s truck that he could see only the radiator of the truck in his rear-view mirror and in his sideview mirror he could not see past the truck because it blocked his vision; that the decedent became nervous because of the proximity of the truck and wanted to get out of its way; that he could not increase his speed owing to traffic ahead of him; that he signaled the turn to the left and tried to edge over into the left lane at which time he heard three loud blasts of a horn from a car in the left-hand lane; and that he then attempted to get back into the middle lane and was struck by the left front of the defendant’s truck. On these claims of proof it would have been permissible for the jury to find that there was a sudden emergency which was not created by the decedent and that he chose the course of action which would or might have been taken by a reasonably prudent driver under the same circumstances. Despite the inadequacy of the plaintiff’s request to charge, it was “sufficient to call the matter to the attention of the court, since the charge should have included instructions on this point, even in the absence of a request.
Foote
v.
E. P. Broderick Haulage Co.,
The plaintiff also assigns error in a ruling by the trial court admitting certain testimony of a New Jersey police officer who investigated the accident. On direct examination by the defendant it was established that the officer had discussed with the dece *314 dent and Hubert A. Abercrombie, the operator of the defendant’s truck, how the collision occurred. Abercrombie is not a party to this action. The officer was asked to relate what Abercrombie had told him about the accident subsequent to its occurrence. The plaintiff objected on the ground that the answer would be hearsay. The defendant claimed that it was part of the res gestae because the statement was made at the scene of the accident and immediately after it occurred. The court inquired if the plaintiff’s decedent was present. Upon receiving an affirmative answer, the court overruled the objection, and the plaintiff duly excepted to the ruling. The officer then testified that Abercrombie stated that he was proceeding south on the turnpike in the center lane at approximately fifty to fifty-five miles per hour; that all of a sudden he saw the car of the plaintiff’s decedent go into a spin, coming to a stop across the road in the center lane; that he could not turn either to his right or his left because of vehicles in those lanes; and that he applied his brakes and struck the decedent’s car. The statement was obviously hearsay and admissible only if it could be shown to be an exception to the hearsay rule.
“Most exceptions to the hearsay rule are permitted because it is believed that safeguards are present which at least approach those given by the opportunity for cross-examination existing where hearsay testimony is not involved.”
Brown
v.
Blauvelt,
There were conflicting versions as to how the accident occurred, and the issue of the credibility of witnesses was of vital importance. By admitting the testimony of the police officer as to what Abercrombie, the defendant’s driver, said to him concerning the accident, the direct testimony of Abercrombie was corroborated by a prior consistent statement. “When the witness has merely testified on direct examination, without any impeachment, proof of consistent statements is unnecessary and valueless. The witness is not helped by it; for, even if it is an improbable or untrustworthy story, it is not made more probable or more trustworthy by any number
*316
of repetitions of it. Such evidence would ordinarily be irrelevant and cumbersome to the trial; and is rejected in all Courts.” 4 Wigmore, Evidence (3d Ed.) §1124. “[T]he general rule is that a party cannot strengthen the testimony of his own witness by showing that he has made previous statements to the same effect as his testimony.”
Palmer
v.
Hartford Dredging Co., 73
Conn. 182, 188,
The defendant urges in his brief that, even if the testimony was erroneously admitted, the ruling was harmless because Abercrombie’s testimony at the trial was the same as that related by the police officer. We have held in numerous cases that, where the facts contained in testimony admitted into evidence by an erroneous ruling are established by other evidence, the ruling is harmless and does not constitute reversible error.
DeCarufel
v.
Colonial Trust Co.,
There is error, the judgment is set aside and a new trial is ordered.
In this opinion the other judges concurred.
