Human factor: Reaction, braking, and stopping
Explanation
The **reaction distance** is the space a vehicle travels from the moment the driver perceives a stimulus, such as an obstacle or a signal, until they respond to that stimulus, for example, by pressing the brake. This reaction time is usually about 0.75 seconds, although it can vary depending on the driver's reflexes, physical and psychological state, and the environment.
It is important to note that the faster a vehicle goes, the shorter the reaction time will be, but it will cover more distance in that time, which means it will reach the danger sooner. Therefore, the **reaction distance** is crucial for driving safety, as it determines how much time and space the driver has to begin responding to an unforeseen event.
