In the forenoon of November 19, 1938, a collision occurred between a mechanical street sweeper owned by the city of San Diego and a Pacific Greyhound bus driven by the defendant J. E. Mort. This collision occurred on U. S. Highway No. 101 in Rose Canyon in the city of San Diego. At the . time the street sweeper had been rented, together with its driver, by David H. Ryan, paving contractor. Mr. Ryan’s insurance carrier, the Continental Insurance Company having paid for repairs to the sweeper took an assignment of the city’s claim for damages and commenced
Upon this appeal all intendments are in favor of the trial court’s findings and they will not be overthrown unless it is manifest that the conclusions reached cannot be sustained on any rational view of the evidence. ‘ ‘ If there is any competent evidence to support the findings they will not be disturbed or if twro different inferences can be reasonably and properly drawn from the facts proved, the findings of the trial court are binding on the reviewing court. In other words, the trial court’s findings are conclusive on appeal unless it can be held as a matter of law that the evidence is without substantial conflict and the only reasonable inference to be drawn therefrom is contrary to the findings;” (Scholz v. Hilbert, 30 Cal. App. (2d) 228 [85 Pac. (2d) 902].)
We may not interfere with the court’s findings on the question of negligence unless the evidence discloses that the only reasonable conclusion to be reached is that no negligence has been established on the part of the defendant J. B. Mort. Such a conclusion, of course, would not be justified by the facts of this case. The passing of cars without sufficient room to return safely to the right-hand side of the road and the driving of the bus into a cloud of dust at an unsafe speed are two of several phases of the evidence upon which the court might have based a finding of negligence. (Bixby v. Pickwick Stage Co., 131 Cal. App. 739 [21 Pac. (2d) 972].)
In answer to these contentions respondent asks us to remember that the sweeper was used in necessary highway repair work; that its peculiar construction required it to proceed in the direction it at the time was going; that there were warning signs at the beginning of the repair area; that the cloud of dust at the place of collision was warning and notice enough; that under the circumstances it could not be said that the operator of the sweeper was guilty of negligence as a matter of law; that he was not even negligent as a matter of fact, and, finally, if he were negligent his negligence did not proximately contribute to the accident in question.
With these contentions in mind we proceed with a brief review of the law. The operator of the sweeper was under obligation to exercise reasonable care and caution in behalf of the traveling public, “yet the right to public use of the highway, while roadwork is being done, is subordinate to the right of the public authorities to cause improvements to be made in the public interest. (Township of Crescent v. Anderson, 114 Pa. St. 643, 647 [60 Am. Rep. 367, 8 Atl. 379].) And even with the exercise of reasonable care and circumspection, the very nature of the work may sometimes create perils against which travelers must be on guard.” (Jones v. Hedges, 123 Cal. App. 742, 749 [12 Pac. (2d) 111].)
The standpoint from which the operator’s conduct is to be judged is that of a person whose duties require him to operate a sweeping machine on the highway in a manner properly to remove the dirt from the highway, and he was justified in assuming that operators of motor vehicles would use reasonable care and caution commensurate with visible conditions and would approach with their cars under reasonable control. Even though there had been a prior accident the operator of the sweeper had the right to presume that if there were sufficient passing room to his left hand that there would be no further difficulty and that motorists using reasonable care could safely pass the sweeper. The fact of this prior accident should have cautioned him to keep said sweeper well against the right-hand curb. The sweeper was in this position when it was struck by the bus, and there was ample passing space, at least twelve feet, to the west of the sweeper. True, there was a cloud of dust which obscured the operator’s vision, but either there was to be this cloud of dust or the machine was not to be operated at all. It was necessary to remove this accumulation of dirt from the highway and the operation could not very well be carried on without the raising of dust. The highway could have been closed to traffic but this would have worked an unnecessary inconvenience to the traveling public. The repairs were necessary, and the manner in which they were being performed and the use of the highway by others presented questions of fact for the trial court to decide. “ It is only when the facts are clear and indisputable and when no other inference than that of negligence or contributory negligence can be drawn from the facts that the issue becomes one of law and not of fact. . . . When honest difference of opinion between men of average intelligence arises as to the effect of the evidence a question of fact arises and the findings of the triers of fact become conclusive upon the appellate tribunals. ’ ’ (McQuigg v. Childs, 213 Cal. 661 [3 Pac. (2d) 309].)
Judgment affirmed.
