Which load requires a greater stopping distance?

The correct answer is that a full load requires a greater stopping distance. When a vehicle is loaded to its maximum capacity, it weighs significantly more than when it is empty. This increased weight directly impacts the amount of force and distance required to bring the vehicle to a stop. Heavier loads result in greater momentum, meaning that when the driver applies the brakes, it takes more time and distance to slow down and stop safely.

Stopping distance is influenced by several factors, including the vehicle's speed, weight, braking system efficiency, road conditions, and tire friction. While an empty load might seem safer in terms of stopping distance, it can lead to greater control issues due to the lack of weight, especially in adverse weather conditions. However, when considering stopping distance alone, a full load clearly necessitates a longer distance due to the laws of physics regarding mass and acceleration.
