In Sheehan v. New York, 40 NY2d 496 (1976) the Court was required to examine the conduct of a bus driver who parked the bus he was operating at an angle causing the rear portion of the bus to partially obstruct the lane for moving vehicles. The argument raised centered on whether failure to pull the bus along side the curb constituted prima facie negligence on the part of the bus driver. The Court nevertheless concluded that "the conceded negligence of the sanitation truck was the sole proximate cause of the injuries and that the continued presence of the bus in the traveling lane at the time it was struck, merely furnished the condition or occasion for the occurrence of the event rather than one of its causes".
