What type of distance is increased by the additional weight in a loaded truck?

1. Perception distance

2. Reaction distance

3. Braking distance

4. All of the above

The correct answer is: All of the above

When a truck is loaded, the additional weight impacts various distances involved in driving safety. Perception distance refers to the length of time it takes for a driver to notice a hazard and recognize the need to react. While increased weight influences the overall feedback in vehicle handling and might impact the driver's perception in more complex driving scenarios, it is more about the driver's awareness than the physical characteristics of the vehicle. Reaction distance is influenced by the time it takes a driver to execute a response after realizing a need to stop or maneuver. Heavier trucks can lead to longer distances required to initiate a maneuver due to inertia; however, this is not as significant as the changes in braking dynamics. Braking distance, however, is directly affected by the additional weight of the load. As the weight increases, the vehicle requires more distance to come to a complete stop because the braking force has to counteract not just the load but also the increased momentum generated by that weight. This relationship is rooted in physics, specifically Newton's laws, where heavier objects require greater force to stop within the same distance. Since the increase in weight influences all three distances—perception, reaction, and braking—acknowledging that all these aspects can be impacted by the additional weight leads to
