It is an offence for any driver to leave the engine of a motor vehicle running when it is stationary for reasons other than traffic conditions.
Problems caused by idling engine
A stationary motor vehicle with engine running (idling) wastes fuel and also causes air pollution. It also causes smell and noise nuisance to the public.
A vehicle parked with engine running can damage the engine in the long term as the engine is not operating at optimum temperature for complete combustion of the fuel. This leaves fuel residues that may contaminate engine oil and make the spark plug dirty.
A vehicle parked with prolonged idling of the engine also allows water to condense in the vehicle exhaust, contributing to corrosion of the exhaust system.
