One day in July, a the driver of a truck owned by a car leasing company, and leased to a delivery company experienced recurrence of a mechanical problem with the truck in which the accelerator pedal occasionally sticks, does not elevate automatically when the driver’s foot is off it, and which the driver is able to correct only by tapping the pedal with his foot. The driver called the mechanics responsible for the maintenance of the truck who instructed him to drive the truck back into Manhattan.
In the afternoon, the truck was travelling westbound on the Long Island Expressway when the pedal stuck again as the truck was descending an incline. At that point the Expressway curved slightly to the left. The driver looked at the pedal for a moment, during which period the truck swerved on to the shoulder of the Expressway, striking two parked buses. A passenger in the bus suffered very severe injuries to his legs.
The passenger filed an action for damages against the truck driver and the bus companies. The bus companies denied liability arguing that the buses were not the proximate causes of the injuries sustained by the passenger.
