During the day, in dense fog or heavy rain, are you allowed to drive with the high beams on?
Lighting
Explanation
To drive safely during the day in conditions of **dense fog or torrential rain**, it is important to understand how to correctly use the vehicle's lights.
- **High beams (road lights):** These lights are useful for improving visibility on poorly lit roads, especially at night or in dark tunnels. However, during the day, in conditions of fog or heavy rain, high beams can reflect off water droplets or fog, reducing visibility instead of improving it.
- **Low beams (dipped headlights):** These are more recommended in these conditions because they do not cause as much reflection and help to better see the road and be seen by other drivers.
- **Fog lights:** These lights are specifically designed to improve visibility in dense fog conditions. They can be used together with high or low beams, but it is important to use them only when visibility is really poor.
Therefore, although it is possible to use high beams during the day in dense fog or torrential rain, it is more advisable to turn on the **low beams** to avoid reflection and improve visibility.
