1. Tunnel

A tunnel is a covered passage that carries a road through or beneath an obstacle such as a hill, mountain, building, waterway or another transport route. Road tunnels may contain one or more traffic lanes and can carry traffic in one or both directions.

Driving in a tunnel requires particular attention because visibility, available escape routes and space for avoiding hazards are limited. Drivers should follow the applicable lighting, speed, lane and following-distance rules and pay attention to emergency exits, traffic signals and variable-message signs.

Which sign indicates a tunnel in Belgium?

The Belgian F8 sign indicates a tunnel with a length of more than 500 metres.

Does a Belgian tunnel sign itself impose a speed limit?
