What is the effect of excessive speeding on stopping distance?

Excessive speeding plays a significant role in increasing stopping distance due to several interconnected factors. As a vehicle's speed increases, not only does the distance required to come to a full stop grow, but the time it takes for the driver to perceive a need to brake and the response time to react also lengthen.

When traveling at higher speeds, the kinetic energy of the vehicle is much greater, which means that more energy needs to be dissipated for the vehicle to come to a halt. This increased kinetic energy translates directly into a longer stopping distance, as the brakes must work harder to overcome this energy.

Additionally, factors such as roadway conditions, tire performance, and the vehicle's braking system also contribute to the overall stopping distance. Higher speeds magnify the impact of these conditions. Therefore, drivers should be aware that speeding significantly lengthens the distance required to stop safely.
