You drive into a brightly lit tunnel which is indicated like this. What do you do?

When driving into a brightly lit tunnel, the appropriate action is to drive with dipped headlights. This regulation is essential for maintaining visibility and ensuring safety within the tunnel. Dipped headlights help to illuminate the road and make your vehicle visible to others, reducing the risk of accidents.

In addition, it is important to note that while daytime running lights may be used under certain conditions, they do not provide the same level of illumination as dipped headlights, especially in darker or enclosed spaces like tunnels. Thus, the requirement is specifically for dipped headlights to ensure adequate lighting effectiveness throughout the tunnel. Following this rule is crucial for complying with German traffic laws and ensuring safe driving practices.
