By what proportion should the safety distance be greater than the reaction distance in normal conditions?
Human factor: Reaction, braking, and stopping
Explanation
To drive safely, it is important to understand the **reaction distance** and the **safety distance**.
- **Reaction distance**: This is the space you cover from the moment you detect an unforeseen event until you react, such as when you see a red traffic light and press the brake. This time is usually approximately 0.75 seconds. The faster you go, the more distance you will cover in that time.
- **Safety distance**: This is the minimum space you must maintain with the vehicle in front to avoid collisions in case of sudden braking. This distance should be greater if you increase speed, if road conditions are poor, or if you are not in good physical or psychological condition.
The **safety distance** should be at least **double the reaction distance** in normal situations. This ensures that you have enough space to stop safely if the vehicle in front suddenly brakes. Maintaining this proportion helps you react in time and avoid accidents.
