COMPANY car drivers could come under fire in Cambridge if plans to fine motorists who leave their engines running are introduced.

Cambridge City Council has launched a public consultation exercise to gauge support for proposals, which it claims would cut congestion and save fuel. The regulations would enable officers to impose £20 fixed penalty notices for drivers who 'unreasonably' choose not to switch off engines while stopped for more than 30 seconds. Motoring groups claim pollution could be made worse by using more fuel restarting engines.
