Explanation
Mandatory lights in insufficiently lit tunnels
- In tunnels, underpasses, and sections marked with "Tunnel" that are **insufficiently lit**, it is mandatory to switch on, at a minimum, the **position lights** and the **low beam headlights (dipped beam)**, **at any time of the day**.
- The **high beam headlights** can only be used if there is no risk of **dazzling** oncoming traffic.
In summary: in a dimly lit tunnel, you must always have **position + dipped beam** on.
