When there are weather conditions that significantly reduce visibility, such as in heavy rain, is it mandatory to use the rear fog light?
Safe driving
Explanation
The **rear fog lights** are a type of lighting used in conditions of very reduced visibility, such as fog, snow, heavy rain, or smoke. These lights are red and are designed to make the vehicle more visible to drivers coming from behind.
- **Use of rear fog lights:**
These lights should be used only in situations of **great necessity**, when weather and visibility conditions are extremely poor. It is not mandatory to turn them on in all situations of heavy rain, as their inappropriate use can dazzle other drivers and cause confusion.
- **Conditions for turning on the lights:**
The vehicle's lights, in general, should be turned on in specific situations, such as during the night or on dark days with little natural light. However, rear fog lights have a more restricted and specific use.
Therefore, it is not mandatory to use the rear fog light in case of heavy rain, unless visibility is really very poor.
