Traffic sign A17: Loose chippings

The A17 sign warns of loose chippings that passing cars can throw up. You see it after a new surface dressing or gravel has been laid, until the surface has settled and been swept.

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.
