Which of the following is NOT a part of total stopping distance?

Total stopping distance is the sum of all the distances covered during the various phases involved in stopping a vehicle, typically including perception, reaction, and braking distance.

Perception distance refers to the length of travel from the moment a rider sees a hazard until they recognize it as a need to stop. Reaction distance is the distance the motorcycle travels while the rider is reacting to the perceived hazard and beginning to apply the brakes. Finally, braking distance is the distance it takes for the motorcycle to come to a complete stop once the brakes have been applied.

Acceleration, however, does not factor into total stopping distance because it pertains to increasing speed rather than slowing down. Therefore, when considering the components necessary for stopping effectively and safely, acceleration is not included. This distinction is crucial for riders to understand how various elements contribute to their stopping capability in different scenarios.
