Parents and carers who drive to the school run have been warned of a little-known mistake that can prove harmful to others around them as well as potentially seeing them slapped with a fine.
The offence concerns idling - leaving your engine running when your vehicle is parked - which releases harmful emissions into the air unnecessarily. Not only is it discouraged by many motoring and environment experts for this reason, but it can also land you on the wrong side of the law.
It may be particularly tempting for drivers to leave the engine on while they're waiting in the car to keep warm while out and about in the winter. But it is an offence to leave your engine running when your vehicle is not in motion under Rule 123 of The Highway Code, according to the RAC.
