Traffic sign A21: Pedestrian crossing

The A21 sign announces a pedestrian crossing. At roadworks this is often a temporary crossing, because the footpath is closed on one side of the street.

Warning signs are triangular with a red border. They warn of a hazard ahead and are normally placed about 150 metres before it (Highway Code, art. 66.2). On a worksite they announce what the driver is about to meet: roadworks, a narrowing, an uneven surface.

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.
