One Nelson was driving plaintiff’s horse, hitched to a Frazer cart, in an easterly direction on the south side of First Avenue. The inside wheel was- one or two feet from the curbing, and the horse was moving at the speed of about seven miles an hour. When halfway between Eleventh and Twelfth .Streets, the defendant’s automobile, operated by himself and moving in the same direction at tbe speed of from ten to fourteen miles an hour, came opposite Nelson without warning of its approach. The estimated distance of- its inside wheel from the outside wheel of the cart' varied from two to- ten feet, and, when some little distance past the horse, some of the witnesses testified that the automobile turned south in front of the horse, while one says it moved straight forward. Neither the horse nor its driver was- aware of the approach of the automobile until it was opposite the latter, when the horse became frightened and turned to the south, drawing the cart wheel on the curbing. This threw the driver out of balance and he lost partial control of the horse. It ran ■ forward until seeing the automobile, which had been stopped ahead of him, when it swerved to the north side of the avenue, running against a telephone pole, and his shoulder was broken. According to the driver, the automobile turned to the south in front of the horse when about ten *384feet ahead, and stopped when thirty feet, from it; while defendant testified that the automobile moved straight on and was 'two- hundred and fifty feet from the horse when it •stopped. There was also a conflict in the testimony as to whether the driver had regained control of the horse when the automobile stopped, and whether it again took fright at the machine, and because of this ran into the telephone pole. Appellant relies on thirty-nine points only for reversal, birt these are condensed in argument into twenty divisions. It would have been helpful had the process of elimination been so far continued as to leave none other than the propositions in dispute. These only need be considered. .
1. Evidence expert testimony admissibiiity. I. Several questiops were propounded to Nelson concerning the characteristics and habits of a horse to which objections were interposed and overruled. As he had been handling horses for twenty years and had observed their habits and conduct, especially frightened, he was rightly held competent to testify as an expert. Such evidence was admissible. Heinmiller v. Winston Bros., 131 Iowa, 32; Moreland v. Mitchell Co., 40 Iowa, 394. But see Kraus v. Ry., 55 Iowa, 338.
2. Evidence: conclusion. The defendant, after testifying to what occurred, was asked whether there was anything in the appearance of the horáe or the position of the driver to indicate that the latter might lose control or that there was danger of trouble. This clearly called for the conclusion of the -witness, and the objection on this ground was rightly sustained, as was also a like objection to the inquiry as to whether he could have gotten farther from the cart in passing without getting on the street car track. The street was sixty feet wide between curbings and paved with a double street car track, the inside rail being twenty-three feet from the curbing. As the width of the automobile was shown, the inquiry merely called for *385computation. Besides, as the trolley posts were in the center of the street, there was no apparent reason for avoiding the track.
3. automibiles operation; reasonable statutes. II. Much of appellant’s argument is on the theory that no duty is owing the driver of a team by the operator of an automobile about to pass him, save as prescribed by sections eight and nine of chapter 53, of the Acts of the 30th General Assembly (sections _ . 157li, 1571h, Code Supp. 1907). The first of these prohibits a speed in a closely built portion of a city of more than a mile in six minutes, and the last provides that “any person operating a motor vehicle shall at request, or on signal by putting up the hand, from a person driving a restive horse, or other draft or domestic animal, bring such motor car immediately to a stop, and, if traveling in the opposite direction, remain stationary so long as may be reasonáble to allow such horse or animals to pass, and if traveling in the. same direction, use reasonable caution in passing such horse or animal.” This does no more than define the duty of the operator of an automobile upon request or signal. It in no way relieves him from the obligation resting upon all travelers on the highway to exercise ordinary care for the safety of others. It in no way relieves him from the duty of exercising reasonable caution in passing a horse or other animal, in the absence of any request or signal. One may travel' in a motor vehicle on the streets, but, in doing so, the care exacted necessarily depends somewhat on the rate of speed,, size and appearance, manner of movement, noise, and the like of such vehicle, as well as the means of locomotion of others on the highway. House v. Cramer, 134 Iowa, 374. As the part of the city in question was closely built, defendant was negligent in moving the automobile at a higher speed than ten miles an hour, as this was in violation of the statute quoted.
*3864. Same: reasonable care. *385The evidence tended to show that a horse though well *386broken is likely to become frightened by an automobile or other vehicle coming from the rear in close proximity to it in passing, unless some warning 'is given. Nor this reason, these machines are supplied with a signal horn with which to sound a warning of their approach. Whether such signal is essential in the exercise of ordinary care must be determined from the circumstances of each case. Possibly had the motor vehicle passed on the other side of the street, there might have been no occasion for giving warning of its approach, for it would have béen more likely to have been noticed and the horse less likely to have - been frightened. But there was evidence tending to show that it was approaching from directly behind the cart, that it turned out barely enough to avoid' colliding with it, and was within a few feet from the horse when passing, and turned in when no more than ten feet beyond. No argument is required to demonstrate that an automobile, making little noise in moving as in this instance, and passing as the evidence tended to show this did, would be likely to frighten an ordinarily wéll-broken horse; and whether the defendant, in operating it as he did in passing, exercised the caution an ordinarily prudent man would in like circumstances, was for the jury to determine.
5. Same negligence: instructions. III. Several instructions are criticised for submitting to the jury whether the defendant was negligent in passing the horse at an excessive rate of speed. This was coupled with the condition that the automobile was moved so close to the horse as to frighten and . cause it to shy onto the curbstone and run away. Enough has been said to indicate that, in our opinion, to come up behind a team with an automobile moving at excessive speed, and pass within a few feet of it without any warning, may be negligent, and the exceptions are not well taken.
In other instructions, the court added the circumstance *387of turning in front of the horse so close as to cause him to become frightened. The evidence was such that the jury might have found that the automobile turned in front of the horse within a few feet after it had been passed, and that this might have increased the fright of the animal, already turned toward or on the curbing.. The driver had testified that had he been warned of the approach of the car he might have controlled the animal, and the circumstances of the omission to sound the signal horn or give other warning, together with the nearness of the automobile in passing, were properly to be considered, in connection with the speed at which the automobile was moving, in determining whether defendant was negligent in its operation.
6. Same. IV. The evidence was such that the jury might have found that after the automobile had passed the driver regained his balance and such partial control of the horse as to direct its course in the street, when the defendant, hearing its approach, stopped his machine some thirty feet ahead and thereby added to'the fright of the horse, causing it to turn to the left and run against the telegraph pole. The attention of the jury was directed to this evidence in connection with the circumstances shown, with the statement that it was for the jury to say “whether the defendant in thus stopping his car was guilty of negligence.” In another instruction, the court had correctly defined negligence, so that no exception can well be taken to this in not indicating the care defendant was bound to exercise. In undertaking to stop, he was aware that the horse had become frightened by the automobile, and had not recovered therefrom, and it was for the jury to say whether, as an ordinarily prudent man, he ought not to have known that in bringing the vehicle, which had scared the horse, tó a stop but a short distance in front of the frenzied animal approaching directly from behind, he would increase its fright and render it more difficult of control; if so, in what he did the jury might have found *388him to have been negligent. Had the horse been given the street, it would seem that the driver might have regained control, at least the jury might so have found. The natural effect of stopping the thing which had frightened it but a short distance away was to furnish an obstacle to his progress which it naturally would attempt to avoid, and this might have been found to have turned the horse from its course, and therefore to have contributed to its injury.
7. Same. Ordinarily a person may stop at any point on the street where he chooses, provided he does not unduly obstruct the way; but in an emergency like this the safety of property and person is involved, and that course is exacted which an ordinarily prudent man would exercise for their protection. Having passed the horse immediately before, and being aware of the fright caused thereby, and that the horse was then running toward the receding automobile with the driver still in the cart, it was incumbent on him to exercise care commensurate with the situation in which he found himself, to the end that no act of his should interfere with the efforts to regain control and save the horse and driver from injury. Whether he so did was fairly an issue for the jury to decide.
8. Same. V. Complaint is made of instruction No. 10 in that it exacted knowledge of the defendant that a horse of ordinary disposition would become frightened at an automobile passing under the circumstances disclosed in the evidence. It was more favorable than required, as all that was necessary was that defendant, as ap ordinarily prudent man, should have known if such were the fact.
9 submission conflicting evidence. Instruction No. 9 is based on the testimony of two witnesses, and, though what they testified to was not in harmony with that of the driver or defendant, it was in the case, and the issue raised thereby properly submitted to the jury. Other *389exceptions to instructions are disposed of by wbat has been said.
10. Use of streets: negligence. VI. Appellant insists that driving the cart so close to the curbing was in itself negligent. We do not think so. The horse was well broken, and the driver had the right to drive it, anywhere in the street he might choose. Nor was he bound to keep a lookout backwards. He had the right to rely upon those approaching from, the rear to do so in the exercise of ordinary care. It also appears that Hirst Avenue was frequented by automobiles, and it is urged. that the driver assumed all the risk of having his horse frightened when driving on that street. He did so assume the risk incident to their.operation in a reasonably careful manner, but no more. Otherwise those manipulating these machines might appropriate any street to their own use, for, if other travelers must assume the risk, they could only go thereon at their peril.
The fourteenth instruction is purely negative, and, even though not comprehensive, it was correct as far as it went.
Instruction No. 16 is-not inconsistent with previous instructions, but rather in explanation that the unlawful speed of the car alone did not warrant a verdict for the plaintiff. Instructions requesting this were included in those given, insofar as containing correct statements of the law. The ruling on the motion to strike portions of the petition was without prejudice. The evidence was sufficient to carry the case to the jury. — The judgment is affirmed.
