HI Negligence — Collision Between Autotruck and Automobile— Injuries to Automobile — Damages — Evidence — Care. — In an action for damages for injuries to plaintiff's automobile when struck by a loaded five-ton autotruck, which was being operated up a steep hill by an employee of defendants, the question as to whether or not the driver of the truck used due care and circumspection, within the meaning of section 121 of the California "Vehicle Act (Stats. 1923, p. 537), in turning from a street railroad track along which he was traveling on to the right-hand side of the paved highway, which he know was more or less spotted with grease which had accumulated on the pavement as the result of oil dripping from motor vehicles, in order to permit a cablePlaintiff appeals from a judgment in defendants' favor in an action brought to recover damages on account of injuries sustained by plaintiff’s automobile, which was struck by a truck owned by defendant T. I. Butler Company and operated by defendant Norman Macintosh.
Plaintiff’s cause of action was based upon an allegation charging that at the time the accident happened the truck was being negligently and carelessly controlled, driven, and operated, which allegation was denied in the answer. The cause was tried on that issue, the trial court finding thereon in defendants’ favor. There appears to be little if any conflict in the evidence regarding the manner in which the collision occurred, the principal question presented for determination being whether the conclusion reached by the trial court to the effect that the truck was not negligently operated is fairly supported by the undisputed facts.
Early in the afternoon On the day of the accident plaintiff parked his automobile along the curb on the right-hand side of Powell Street, between Bush and Pine Streets, San Francisco, leaving it there while he attended a theater. The ascent in the grade on Powell Street between the two intersecting streets mentioned is about twenty-three per
[2] Appellant furthermore contends, upon the assumption that the presence of the black streak of oil on the right-hand side of the street made it impracticable to travel on that side, that if it were necessary for the truck driver to divert his course at all, in order to let the cable car pass, he should have turned on to the left side of the street, and in furtherance of this theory sought to show on cross-examination of the truck driver the condition of the pavement on the left side of the street; but the trial court excluded the testimony, and the ruling is assigned as error. We find no merit in the point, because, as already shown, the evidence failed to establish that it was impracticable to travel on the right half of the street, and, therefore, the question of the condition of the left half thereof became immaterial. As was said by the trial court when making the ruling complained of, the law required the driver, under the circumstances present, to use the right side of the street, and hence he could not be deemed guilty of negligence for not using the left side thereof.
[3] We find no error in the trial court’s rulings sustaining respondents’ objections to certain hypothetical ' questions propounded to appellant’s expert witness. One of the questions asked was: “If the brakes on a truck are in proper condition, and the brakes are properly applied, even going up a hill, will the truck slide back?” Another was, after particularizing the Powell Street hill with which the witness said he was familiar, “State whether or not if the brakes of a truck going up that hill, a five-ton truck carrying approximately a five-ton load, are properly applied, whether or not the proper application of the brakes would stop the truck.” It will be noted that the very element which was shown by the testimony of all witnesses to the accident, including that of a traffic officer, to have been the sole contributing cause of the backward movement of the truck, namely, the greasy condition of the pavement, was wholly omitted from both questions. If, therefore, appellant was seeking to prove that the accident could have been averted by the proper application of effec
[4] But, assuming that such hypothetical questions had included the essential element mentioned, they would still have been objectionable, for the reason that the question of what the effect would be of locking the wheels on a loaded five-ton truck sliding backward down hill on a twenty-three per cent brick-paved grade spotted with an unknown quantity of grease obviously would be problematical and could not be determined from like experiences or as a result of professional research, which is substantially the basis of expert testimony.
There was no question involved here as to the distance in which a motor vehicle might be stopped under ordinary road conditions, by the proper application of effective brakes, as was presented in Berkovitz v. American River Gravel Co., 191 Cal. 195 [ 215 Pac. 675 ]; nor does the question arise as to whether the driver negligently omitted to do something which a prudent person would have done in handling the truck after the emergency arose, which was the issue in the case of Alameda County v. Tieslau, 44 Cal. App. 332 [ 186 Pac. 398 ], for the only evidence given on this point was that the brakes were fully and effectively applied as soon as the wheels lost traction in the grease The rules of the cases cited upon which appellant relies are, therefore, not controlling here.
[5] Macintosh testified that when the wheels of thej truck first lost traction and the clutch “burst out” he fully applied the brakes and that they were in good working order, but that the application of the brakes did not prevent the retrograde movement of the truck; that there-} after it continued to slide, the rear wheels at times revolving slowly backward. In this connection the third hypo thetical question objected to was: “If the brakes of a larg' truck are in good working condition and those brakes an applied, will the wheels of that truck revolve?” Plainti: did not plead the matter of defective brakes as an element} of negligence, but assuming that under the general issu the trial court might well have allowed the question tcj be answered, a negative reply thereto would not necessarily have been in conflict with the testimony given by Mac
Appellant urges additional points relating to the sufficiency of the evidence supporting a finding of the trial court that appellant’s loss was covered by a policy of indemnity insurance and that the damaged automobile had been repaired by the insurance carrier and not by plaintiff; also that, regardless of the cost of the repairs, appellant was entitled to damages for the loss of the use of the automobile; but in view of our conclusion that the trial court’s finding to the effect that respondents were not negligent is fairly sustained by the evidence, we deem it unnecessary to inquire into the additional points mentioned.
The judgment is affirmed.
