Traffic sign C3: No access

The C3 sign forbids access to any driver, in both directions. It is the sign used to close a street for works. An additional panel creates an exception, for example "except local traffic" or M2 "except cyclists".

Prohibitory signs are round with a red border. They forbid something: a direction, access, overtaking, driving faster than a set speed. At roadworks they close a street or a footpath, or limit the speed along the site.

Anyone who puts up a traffic sign on the public road for works needs the consent of the road authority: through the occupation permit or through a signage permit with a signage plan. Without that consent you may not put up the sign.
