Which light is it mandatory to switch on in case of heavy snowfall?
Lighting
Explanation
In case of a **heavy snowfall**, it is mandatory to turn on the **rear fog light**. This light is essential to improve the visibility of the vehicle from behind in low visibility conditions, such as those that occur during a heavy snowfall.
- The **rear fog light** helps other drivers see your vehicle in time and maintain a safe distance, reducing the risk of accidents.
- The **hazard lights** and the **brake light** are not designed to improve visibility in snowy conditions. Hazard lights are used to warn of a stop or emergency situation, and the brake light is activated when braking, not for reduced visibility conditions.
Therefore, to ensure road safety during a heavy snowfall, it is crucial to use the rear fog light.
