What should you primarily consider when evaluating how to stop a loaded vehicle?

When evaluating how to stop a loaded vehicle, both the weight of the vehicle and its speed are crucial factors. The weight of the vehicle impacts the amount of kinetic energy it has; a heavier vehicle has more kinetic energy, which requires more force and distance to stop safely. Similarly, the speed of the vehicle is equally important, as a faster vehicle also has greater kinetic energy and requires a longer stopping distance.

In practice, when you combine both the weight (load) and speed of the vehicle, you can accurately assess the appropriate stopping distance and braking force needed to bring the vehicle to a safe stop. This knowledge is vital for making informed decisions in different driving environments, ensuring safety for both the driver and others on the road.
