About regulatory signs
Regulatory signs are usually white rectangles with black or red markings, and they carry the force of law — speed limits, turn restrictions, right-of-way. Ignoring one is a traffic violation. The written test regularly checks whether you know exactly what a regulatory sign requires you to do.

A truck symbol inside a red circle with a diagonal line means:
- A. A truck weigh station is coming up
- B. Trucks must move into the right lane
- C. Truck parking is available ahead
- D. Trucks are not allowed to use that road
Show answer
D. Trucks are not allowed to use that road — A red circle and slash prohibits whatever it covers. Over a truck symbol it closes the road to the trucks described, usually for weight, height or noise reasons, and a driver of one has to find another route.
