What must you observe when you enter a tunnel?

When entering a tunnel, it’s important to drive with dipped headlights even during the day, as well as to take off your sunglasses. The reason for using dipped headlights is to ensure that your vehicle is visible to other drivers in the often reduced lighting conditions, even in well-lit tunnels. Sunglasses can significantly reduce visibility, so removing them helps you see more clearly.

Switching on fog headlamps is generally not necessary unless visibility is severely impaired due to fog or similar conditions. Following these rules helps maintain safety and ensures that all vehicles can navigate the tunnel effectively. Understanding and adhering to these regulations is crucial for preventing accidents and ensuring the safety of all road users.
