ROAD signs hidden by overgrown bushes are endangering drivers' lives and could lead to driving restrictions being unenforceable, the AA has claimed.

A newly published code of practice put together by the Department of Local Government, Transport and the Regions, local authorities and the police says roadside vegetation should be cut back more often. The AA is keen to monitor the situation, ensuring highway authorities stick to their legal responsibility to keep signs clear.

It is urging drivers to report hidden signs to their local councils, and says fleets should consider claiming against the highway authority if they have an accident as a result of unreadable warnings.

Paul Watters, head of roads and transport policy for the AA said: 'It is even getting to the stage where the police may not be able to enforce speeding offences if speed limit signs are covered. Signs are essential for road safety, but if they can't be read they may as well not be there in the first place.'
