At one time it was illegal to get out of your car and leave the engine running even for a few seconds. I think this law was changed to cover things like posting a letter in a roadside box etc. Can anyone settle an argument between friends, no incident is involved ? Thanks
The law has not changed. It is a contravention of Regulation 107 of the Road Vehicles (Construction and Use) Regulations 1986 (and thus an offence under Section 42 of the Road Traffic Act 1988 as amended) to leave a vehicle unattended with its engine running, as this driver found out...
I thought it was illegal to have your engine running while the vehicle was stationary (except in line of traffic, at trafiic lights). Stationary as being waiting for someone, posting letter etc
