Road Works Signs Explained

Road works signs warn drivers about temporary changes to normal road conditions. They provide important information about hazards, speed limits, lane closures and changes in traffic arrangements caused by maintenance work.

Drivers should slow down, follow temporary signs and stay alert for workers, construction vehicles and unexpected changes in road layout. Temporary speed limits at road works are mandatory and must be obeyed.

Lane closure signs and works vehicle signals help drivers move safely through restricted areas. Drivers should follow arrows, keep a safe distance and avoid sudden lane changes near road works.

Real-Life Examples

Example 1: A driver sees a road works warning sign and reduces speed because workers or temporary hazards may be ahead.

Example 2: A driver approaches a temporary lane closure and moves into the correct lane before reaching the closed section.

Example 3: A driver passes a works vehicle only in the direction shown by the arrow and does not enter the restricted area.

Example 4: A driver follows a temporary speed limit through road works even when there are no workers visible.
