Opinion by
Mr. Justice Fell,It appears from the testimony that the plaintiff’s horse became unmanageable at Woodland avenue and Walnut street, and ran with him down Walnut to the crossing of Fourth street, where the accident occurred. During all this time, although the plaintiff kept his seat, the horse was more or less beyond his control and at the time of the accident it appears to have *224Deen a runaway going at a high rate of speed. When from sixty to eighty feet from the crossing of Fourth street, and on the south side of Walnut street between the curb and the car track, the plaintiff saw a car which was going south on Fourth street and about to cross Walnut. As soon as he saw the motorman, the plaintiff called to him to stop the car. The motorman, however, either did not hear, or if he heard elected to do otherwise, for the car proceeded to cross the street, and the horse ran into it, causing the plaintiff’s injury.
We are unable to see in this testimony any evidence of negligence on the part of the motorman. There is no evidence that he heard the plaintiff call to him or that he was otherwise made aware of the approach of the runaway horse. It was his duly, undoubtedly, to look for approaching cars and other vehicles which might collide with his car; but anything moving with the speed of a runaway horse was not to be apprehended, and he might very well have assured himself that none of the ordinary dangers of street crossings threatened him without having either heard or seen the approach of the plaintiff. He had not brought his car to a full stop at the crossing, nor was there, as far as the testimony shows, any reason why he should. A motorman certainly cannot be required to stop at every crossing and look for such extraordinary perils as the one in this case, nor can he be required to stop at all unless the circumstances are such that it would be imprudent for him to do otherwise. In this case, it being Sunday and the streets consequently comparatively clear of travel, and there being nothing on Walnut street which, if moving at a reasonable rate of speed, would have collided with him, a full stop would have been entirely uncalled for.
But even assuming that he knew the situation perfectly, it cannot be said that he was bound upon being confronted by so sudden and immediate a danger to do what after mature deliberation would have seemed to a prudent man to be the wisest thing under the circumstances. Where the sole basis of liability is the omission to perform a certain duty suddenly and unexpectedly arising, there must be not only a consciousness of the facts which raise the duty on the part of the person who is charged with its performance, but also a reasonable opportunity to perform it: Hestonville, etc., R. R. Co. v. Kelley, 102 Pa *225115. And what opportunity had this man? If he had any notice of the impending danger, it must have come to him when he was well started on his way across the street, and it is quite possible that he took the best course which could have been conceived upon such short notice. The outcome, it is true, was disastrous; but how could the jury say that he, with the duty uppermost in his mind of saving his passengers if possible from an imminent collision, did not judge, and that with reason, that his best chance of doing so lay in attempting to clear the runaway’s course ahead of it? And how could they say that such a course would not have seemed to the majority of prudent men, if placed as he was, to have been the best? I f he had stopped the car, it is probable that it would have lain directly across the middle of the street, or nearly so; and if he knew anything of horses, he knew that no human foresight can predict the course of a runaway, even for a short space, and that the horse was as likely to attempt to go around his car at the mar as at the front, and that if maddened by fright it might dash into his car no matter in what part of the street it was.
The second assignment of error is sustained, and the judgment is reversed.
