The sole question involved on the various assignments of error which we deem necessary to consider is, Was there evidence, under the most favorable view that can be reasonably taken of it, to warrant a verdict for the plaintiff ? If there was not, and that situation was apparent at the close of plaintiff’s case, the court erred in denying the motion for a nonsuit. If such was the situation at the close of the evidence on both sides, the motion for the direction of a verdict should have been granted, and the errors in denying the two previous motions of course were repeated in failing to set the verdict aside and grant a new trial.
The circumstances of the accident, as shown conclusively by the evidence, are substantially as follows: It occurred in the early par£ af the evening, a little after dark, on a railway track laid on a broad, level, raised street, not crossed *148by any other street for a distance of about 2,400 feet. On the -west side of the street were two electric railway tracks, occupying some twelve feet in width. .At a safe distance east of the tracks there was a macadamized roadway about twenty feet wide, specially fitted for public travel by vehicles, and east of that for a distance of some fifty feet the street was reasonably level and smooth so there was ample opportunity for teams to pass each other by night or day without driving onto the railway tracks. Plaintiff, while proceeding north, riding in a phaeton drawn by one horse, traveling on the macadamized roadway behind a heavy wood wagon, turned to the left and drove onto the railway track for the purpose of passing such wagon. The reason given for driving to the left instead of to the right was that plaintiff deemed the latter a little rough so that, had she turned that way, the parcels she had in the phaeton were liable to fall out. She drove at quite a brisk trot as she turned to the left and drove onto the railway track. She had proceeded, in endeavoring to pass the wood wagon, but a short distance when she was run into by a car going in the same direction. That caused the injury. She said she looked and listened for a car before driving onto the track, but did not see or hear any. The car was in perfect condition, being supplied with all the customary appliances, such as a brake, a suitable headlight, and a signal bell. It was running at a lawful rate of speed and the motorman was at his post, keeping a sharp lookout ahead. As he approached the teams driving along at the right of the track, and before plaintiff turned toward the track, he sounded his signal bell. As soon as he observed the movement of the horse toward the track he sounded the bell, and immediately turned off the current and did all that was in his power by applying the brake to stop the car. It nevertheless ran into the plaintiff’s phaeton, throwing it off the track to the right, plaintiff at the same time falling out of the phaeton to the *149left. After the collision the car went about two or three car lengths and stopped. The wrecked phaeton was then found in the roadway behind the wood wagon. /
We search in vain in the foregoing to find any support whatever for the charge of negligence contained in the complaint. In view of that, upon what theory the learned trial judgé submitted the case to the jury we are unable readily to perceive. Without any evidence whatever to sustain the charge of negligence made in the complaint, but, on the contrary, in the face of evidence showing that everything was done td guard against all dangers reasonably to have been apprehended respecting the personal safety of plaintiff as she was traveling on the road along the street-car track, and to warn her off the track when she turned to the left, and to avoid injuring her after she entered upon the track, it was left to the jury to say whether the defendant was culpably negligent or not, as if negligence under the circumstances were a disjDuted question of fact. The rule seems to have been overlooked that when the evidentiary facts are all undisputed and there is only room for one reasonable inference as to the ultimate fact in issue, it is for the court to draw the proper inference as a matter of law. There does not appear to be a scintilla of evidence tending to show negligence on the part of defendant. The only evidence in that regard, claimed by plaintiff’s counsel, is that the motorman did not use reasonable diligence after he saw, or might have seen, the plaintiff turn toward the track. That is predicated solely on the theory that plaintiff’s testimony shows, or tends to show, that she traveled the distance requisite to pass two or three teams before she was struck by the car. A careful examination of her evidence leads to the conclusion that the jury were not warranted in saying from it that plaintiff passed more than one team before the accident, while the undisputed fact in the case, that the wrecked phaeton was found immediately after the accident behind the wood wagon *150shows that it must have been struck very soon after the horse turned in upon the track and before it had time to pass such wagon far enough to turn to the right ahead of it. It is easy, to see how plaintiff might have been mistaken, in view of the very uncertain nature of her evidence and her interest in the result'of the trial; but the undisputed fact as to the location of the wrecked phaeton with reference to the "wood wagon leaves no room for a reasonable belief other than that plaintiff had not passed fully by that wagon before the car reached her. All the evidence and all reasonable inferences therefrom are consistent with that theory, and with no other; so if there were anything in plaintiff’s evidence, standing alone, tending to show that she had passed two or three teams before, and we say there is not, the rule of law often announced, that the testimony of an interested party contrary to the facts otherwise conclusively established in the case and all reasonable inferences from the situation disclosed by the evidence, does not raise a conflict requiring a finding by the jury. Flaherty v. Harrison, 98 Wis. 559; Badger v. Janesville Cotton Mills, 95 Wis. 599.
So it follows, as before stated, that on the question of defendant’s fault 'there was not only no evidence tending to establish the allegations of the complaint, but the evidence affirmatively established the contrary. The failure, therefore, to grant the nonsuit and to direct a verdict for defendant, and to set aside the verdict and grant a new trial, are errors too plain to require more to make them apparent than a mere statement of the facts-established by the evidence.
But, if it were not for the failure to establish negligence of the defendant, plaintiff could not recover on account of her contributory negligence, which appears as a matter of law from the undisputed facts. The situation was such that it was plaintiff’s duty, in the exercise of ordinary care, to look and listen before going upon the track. ¿That is con•.ceded. The court so instructed the jury in the following *151language: “ It is negligence as a matter of law for a person to drive upon the track of an electric railway without looking or listening for approaching cars; ” and again, “If you find from the evidence that plaintiff went onto the railway track without looking carefully down the track for cars, then your verdict must be for defendant.” The effect of those instructions, obviously intended, was that if the plaintiff knew, or might have known, by the use of her senses of seeing and hearing, that a car was approaching in dangerous proximity when she drove upon the track, she was guilty of contributory negligence, precluding a recovery. Thai is the law respecting the duty of persons to avoid danger from injury upon electric railway tracks, as well as upon steam railway tracks, as is abundantly shown by cases cited in defendant’s brief. Young v. Citizens' St. R. Co. 148 Ind. 54; Everett v. Los Angeles C. E. R. Co. 115 Cal. 105; Hall v. West End St. R. Co. 168 Mass. 461. See, also, Omslaer v. Pittsburg & B. T. Co. 168 Pa. St. 519; Flanagan v. People's P. R. Co. 163 Pa. St. 102; Henderson v. Detroit C. St. R. Co. (Mich.), 74 N. W. Rep. 525; Blaney v. Electric T. Co. 184 Pa. St. 524; McQuade v. Metropolitan St. R. Co. 17 Misc. (N. Y.), 154; Booth, St. Ry. Law, §§ 311, 312; Kane v. People's P. R. Co. 181 Pa. St. 53. In Omslaer v. Pittsburg & B. T. Co., supra, it is said that the rule of “ look and listen ” before attempting to cross the tracks of a steam railroad is inflexible, and that the nonobservance of it is negligence per se. The rule is just as applicable to the crossing of a •street-railway track operated by a cable or electricity, and we need not go outside of our own court to find that extension of it. In Johnson v. Superior R. T. R. Co. 91 Wis. 233, the present chief justice said, in effect, that if a person drive upon a street-railway track without looking for approaching cars, and receive an injury, and the facts in that regard appear conclusively in a subsequent action by the injured party against the railway company for damages, it is the duty of *152the court to nonsuit the plaintiff or direct a verdict in favor of the defendant.
The theory upon which the court sent this case to the jury on the subject of contributory negligence manifestly was that, conceding the rule of law requiring plaintiff to look and listen, her testimony that she did so was sufficient to require the jury to find where the trouble lay, as if it were permitted to them to say on such evidence that she did in fact look and listen and yet did not see or hear the car that was unquestionably in plain sight and hearing. In that there was a failure to observe the limits beyond which a jury cannot go. They cannot_ go beyond the boundary of reasonable probabilities in determining facts from evidence without going into the realms of conjecture or perversity. This court has often held that the rule of law that requires a person to look and listen before going upon a railway track requires him to see and hear an approaching car if it is so located as to be plainly within view and hearing; that evidence of a person so circumstanced, that he looked but did not see, or listened yet did not hear, the car, if believed at all, is only to establish contributory negligence by showing that he knowingly placed himself in a place of danger. Groesbeck v. C., M. & St. P. R. Co. 93 Wis. 505; Schneider v. C., M. & St. P. R. Co. 99 Wis. 378; Steinhofel v. C., M. & St. P. R. Co. 92 Wis. 123; Haetsch v. C. & N. W. R. Co. 87 Wis. 304. In Burke v. N. Y. C. & H. R. R. Co. 73 Hun, 32, the court said, if a person looks he is supposed to do so for the purpose of seeing, and if the object is in plain sight and he apparently looks but does not see it, it is manifest that he does not do what he appears to do and has not complied with the rules of law. On the same subject in Young v. Citizens’ St. B. Co. 148 Ind. 54, the court, by Mr. Justice McCabe, stated the rule thus: “If a traveler by looking could have seen the approaching train in time to escape, it will be presumed, in case he is injured by a collision, either *153that he did not look, or if he did look that he did not heed what he saw. Such conduct is negligence per seAnd again, the same court, in Cones v. C., I., St. L. & C. R. Co. 114 Ind. 328, further emphasizing the rule as one of law,, said: “The law will presume that he saw what he could have seen if he had looked, and heard what he could have heard if he had listened.” In Blaney v. Electric T. Co. 184 Pa. St. 524, the supreme court of Pennsylvania used language quite as strong, as witness the following: “ "When a person places himself in danger, and is struck by a car on a road that is in plain sight and hearing, the unavoidable inference is that he did not look for a car when ordinary intelligence and prudence disclosed that there might be one, or, seeing one perilously near him, placed himself in its way.”
So we may say that the duty is absolute to look and listen before going upon either a steam railroad track or an electric street-railway track, and to see and hear an approaching car, if within plain view and hearing to a person exercising his senses of hearing and seeing with ordinary prudence to detect it, having regard for the dangers reasonably to be apprehended, and that failure to perform that duty, or, after-performing it, to keep out of the region of danger, is negligence per se; that it is not a mere rule of evidence which a jury may be permitted to consider, and say there was or was not negligence in a given case, according to their notions,, but that it is a rule of law to be applied by the court when the facts are undisputed, and by the jury under the direction of the court when the facts are disputed. Thus far, at least, the law-of negligence has proceeded in the natural process of development, through the wisdom of courts in adapting old principles to new conditions brought about by the means-of rapid transit through populous districts, demanded by the times, and the dangers incident thereto, and the mutual obligations of the various members of the community to shape their conduct with reference to the circumstances surround*154ing them and administering daily to their comfort, prosperity, .and happiness. The bench and bar, and litigants as well, will partake of benefits that unquestionably flow from having definite and certain rules of law so far as practicable on this most important branch of jurisprudence recognized and enforced.
Candor compels us to say that in this case the learnqd trial court appears to have shifted a duty onto-the jury which was plainly judicial, and when they failed to discharge it properly, allowed the result to stand as the law of the case. The jury did not find the fact because there was no controversy in that regard. They said that conduct on the part of defendant was actionable negligence, and conduct on the part of plaintiff was consistent with ordinary care, when the proper application of well-settled rules of law would have led to a contrary result.
The peculiar circumstances of this case move us to reiterate what has often before been said by this court, that though the rule that where there is any credible evidence which, under any reasonable view of it, will sustain a recovery, and there is opposing evidence, it is for the jury to say where the truth lies, should be firmly adhered to, where the evidence is clearly susceptible of only one reasonable inference, the motion for a nonsuit, or the direction of a verdict accordingly, should be granted as a matter of right, which implies a judicial duty to decide that way and hot to abrogate the judicial function and shift it onto the jury. Finkelston v. C., M. & St. P. R. Co. 94 Wis. 270. A proper administration of justice requires that such a situation should be met and the duty involved be discharged as contemplated by our judicial system, just as much as that the province of the jury to decide the facts from the evidence, where there is any conflict in that regard, should not be invaded by the court. The scope of judicial duty, and of that of the jury as well, is clearly marked, and a failure to maintain *155the integrity and inviolability of either is subversive to the system itself, and tends to throw doubt upon its efficacy to ■secure the highest attainable degree of justice between individuals, and to promote the ends of good government.
By the Gourt.— The judgment of the circuit court is reversed, and the cause remanded for a new trial.
