When driving in heavy snowfall, which fog light must be switched on?
Lighting
Explanation
To drive safely during a **heavy snowfall**, it is essential to use the appropriate lights to improve visibility and be seen by other drivers. In these conditions, it is recommended to turn on both the **rear fog light** and, if available, the **front fog light**.
- **Rear fog lights**: These lights are red and are designed for situations of very low visibility, such as dense fog, heavy snow, heavy rain, or smoke. Their main function is to make the vehicle more visible to drivers coming from behind, reducing the risk of collisions. They should only be used when conditions require it due to their intensity.
- **Front fog lights**: These lights can be white or yellow and help illuminate the road in adverse conditions. Although they are not mandatory, they are useful for improving the driver's forward visibility during heavy snowfall.
In summary, during a heavy snowfall, it is advisable to turn on the rear fog light to be seen by other drivers and, if the vehicle is equipped, also the front fog light to improve road visibility.
