Is it true or false that empty trucks have the best braking ability?

The assertion that empty trucks have the best braking ability is false. When a truck is empty, it often experiences a longer stopping distance compared to when it is loaded. This is due to the decreased weight on the axles, leading to less friction between the tires and the road surface. Heavier loads provide better traction, which can enhance braking performance.

Moreover, an empty truck may be more susceptible to skidding, especially on wet or slippery roads, since the lack of weight reduces its stability and grip. Therefore, a loaded truck can often stop more effectively under normal conditions. Concepts of vehicle dynamics and braking principles underscore why loads can influence a truck's braking efficiency, leading to the conclusion that the statement is false.
