CDL Passenger Transport (P Endorsement) Practice Exam

What factor greatly affects a bus’s stopping distance?

Engine type Vehicle weight and speed Passenger count Weather conditions

Correct Answer:

Vehicle weight and speed

Explanation:

The stopping distance of a bus is significantly influenced by its vehicle weight and speed. Heavier buses require more distance to come to a complete stop due to the increased momentum they possess at any given speed. The greater the weight, the higher the force required to slow down the vehicle. Additionally, speed directly impacts stopping distance; as speed increases, the distance required to stop proportionately increases because of the kinetic energy involved. This relationship highlights the importance of both factors in determining how quickly a bus can stop safely, making them critical considerations for any bus driver to keep in mind while operating the vehicle.
