Traffic sign A33: Traffic lights

The A33 sign announces traffic lights. At roadworks these are usually temporary lights that let traffic pass a narrowing in turns.

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.
