Traffic sign C1: No entry

The C1 sign forbids any driver from entering the street in that direction; traffic may still come from the other direction. At roadworks it is used to create a temporary one-way street, together with the F19 sign at the other end.

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.
