What does stopping distance depend on?

Correct answer

Speed, reaction time and braking distance.

Stopping distance, which is the space needed to bring a vehicle to a complete stop from the moment the driver perceives a hazard, depends on several important factors. Firstly, the vehicle's speed is crucial: the higher the speed, the greater the stopping distance, both because of reaction time and braking distance. The driver's reaction time also affects stopping distance. This is the interval between detecting the hazard and reacting by applying the brakes. If the driver is distracted, tired or under the influence of substances such as alcohol, their reaction time may increase, which will increase the stopping distance.
