Councils will soon be able to apply for powers to fine motorists for offences like stopping on a yellow box junction, but many drivers fear it could become a money-making scheme.
Offences including 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.
From Tuesday, May 31, all local authorities in England and Wales will be able to apply for the power to fine motorists, from £20 for lower level fines paid promptly, up to £105 for late payment of more serious transgressions, such as parking on a cycle path.
