A council in the Bristol region has "expressed an interest" in powers to fine motorists for offences like stopping on a yellow box junction.
Moving traffic offences - which also include driving in a bus lane, making an illegal U-turn and going the wrong way down a one-way street - can only be enforced by the police, in most areas of England and Wales. The only current exceptions are London and Cardiff.
But from Tuesday, May 31, all local authorities in England and Wales have been able to apply for the power to fine motorists, from £20 for lower level fines paid promptly, and up to £105 for late payment of more serious transgressions, such as parking on a cycle path.
