Drivers who leave their engines running while de-icing vehicles could face fines of up to £40, the RAC has warned. The motoring organisation says many motorists unknowingly break the law by idling their cars unattended on public roads during cold weather.
Under the Road Traffic (Stationary Engined Vehicles) Regulations 1986 and Rule 123 of the Highway Code, leaving a vehicle's engine running whilst not inside the car constitutes an offence. This applies even if drivers are just metres away at their front door.
Police forces and local authorities can issue fixed penalty notices of £20 for the offence. If unpaid, the fine doubles to £40. The regulations target practices that contribute to air pollution and create security risks through potential vehicle theft.
The RAC highlighted environmental concerns beyond the legal implications. Unnecessary idling releases pollutants into the atmosphere, worsening air quality particularly in urban areas. This conflicts with government initiatives to reduce emissions and improve public health.
Drivers should use alternative de-icing methods including sprays, scrapers, or protective covers to avoid penalties and reduce their environmental impact. The RAC stressed that keeping engines off when not actively driving remains essential for legal compliance and responsible ownership.
