Bus driver: Had the garbage truck not been exceeding the speed limit, it would not have collided with the bus I was driving. I, on the other hand, was abiding by all traffic regulations -- as the police report confirms. Ttherefore, although I might have been able to avoid the collision had I reacted more quickly, the bus company should not reprimand me for the accident. Which one of the following principles, if valid, most helps to justify the reasoning in the bus driver's argument? ['A company that employs bus drivers should reprimand those drivers only when they become involved in collisions that they reasonably could have been expected to avoid.', 'A bus company should not reprimand one of its drivers whose bus is involved in a collision if a police report confirms that the collision was completely the fault of the driver of another vehicle.', 'If a vehicle whose driver is violating a traffic regulation collides with a vehicle whose driver is not, the driver of the first vehicle is solely responsible for the accident.', "When a bus is involved in a collision, the bus driver should not be reprimanded by the bus company if the collision did not result from the bus driver's violating a traffic regulation."]
