The reaction distance...
Human factor: Reaction, braking, and stopping
Explanation
The **reaction distance** is the space you cover from the moment you detect an unexpected event until you can react, such as when you see a red traffic light and press the brake. This distance **depends on the speed** at which you are traveling. The faster the vehicle moves, the more distance it will cover in the same reaction time, which means the reaction distance will be greater.
Therefore, the reaction distance is not constant and does not depend solely on the psychophysical state of the driver, but is directly related to the speed of the vehicle.
