When driving in a tunnel, you should use your dipped headlights (also known as low beam headlights). This is important to ensure you can see clearly and be seen by other drivers in the darker tunnel environment. Using dipped headlights in tunnels is often a legal requirement, and it is recommended to turn them on manually before entering the tunnel. Rear fog lights and full- beam (high beam) headlights should not be used in tunnels as they can blind other drivers. Daytime running lights alone are not sufficient for visibility in tunnels because not all vehicles have rear daytime running lights.
Key points about lights in tunnels:
- Use dipped headlights for visibility and safety.
- Turn on dipped headlights manually before entering the tunnel.
- Do not use rear fog lights or full-beam headlights in the tunnel.
- Daytime running lights are not enough for visibility inside tunnels.
- Avoid wearing sunglasses inside tunnels.
These guidelines help to reduce driver fatigue and improve overall safety while passing through tunnels.
