The stopping distance is equal to the sum of which two components?
Human factor: Reaction, braking, and stopping
Explanation
The **stopping distance** is the total space a vehicle travels from the moment the driver detects an obstacle until the vehicle comes to a complete stop. This distance is composed of two parts: the **reaction distance** and the **braking distance**.
- **Reaction distance**: This is the space the vehicle travels during the time it takes for the driver to react and begin braking after detecting an obstacle.
- **Braking distance**: This is the space the vehicle travels from the moment the driver applies the brake until the vehicle comes to a complete stop. This distance can vary depending on factors such as the vehicle's speed, the load it carries, the vehicle's technical conditions (such as the state of the brakes and tires), the weather, and road conditions.
Therefore, the **stopping distance** is the sum of the **reaction distance** and the **braking distance**. This combination is crucial for understanding how and when a vehicle can stop safely.
