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.
