As freezing temperatures grip the UK, motorists are being warned that a common morning ritual could land them with a hefty penalty. Highway experts have issued a stark reminder that drivers could be fined up to £1,000 for repeatedly defrosting their car incorrectly.
The £1,000 Idling Offence
The Royal Automobile Club (RAC) Foundation has highlighted the legal risks of leaving a vehicle's engine running unattended on a public road while waiting for ice to melt. This act, known as "idling", contravenes Rule 123 of the UK Highway Code and breaches Regulations 98 and 107 of the Road Vehicles (Construction and Use) Regulations 1986.
Initially, failing to switch off your engine when instructed can result in a £20 fixed penalty notice. If unpaid within 28 days, this rises to £40, and then to £80 if still outstanding after a further two weeks. For repeat offenders, the fine can escalate to a maximum of £1,000.
The RAC notes that an idling stationary engine is a significant pollutant, producing up to twice as many emissions as an engine in motion. The Royal College of Physicians estimates that air pollution, to which idling contributes, is linked to around 40,000 deaths annually in the UK.
Dangerous Defrosting and 'Portholing'
Legal expert Gary Rycroft, speaking to BBC Morning Live, cautioned that fines aren't only for idling. Using a vehicle with parts in a "dangerous condition"—such as an improperly cleared windscreen—can lead to a £60 fine and three penalty points.
He specifically warned against the practice of "portholing", where drivers scrape only a small, circular viewing hole in the frost. This creates a severe blind spot. Clearing only the driver's side is insufficient; the entire windscreen must be properly de-iced, using wipers only after the ice has fully melted.
There is also a significant theft risk. Over the years, many vehicles have been stolen after owners left them running with the keys in the ignition while the ice thawed.
How to Defrost Your Car Safely and Legally
The RAC provides clear guidance for a legal and safe defrost. The key is preparation: invest in a dedicated ice scraper and de-icer spray. Apply the de-icer first, then clear the ice with the scraper.
Always check your wipers are not frozen to the glass before turning them on, as forcing them can burn out the motor or tear the blades.
For a homemade solution, you can use:
- A basic mix of water with a teaspoon of salt poured over affected areas.
- A spray bottle with a solution of three parts vinegar to one part water.
Experts strongly advise against using boiling water, which can crack the glass, or makeshift tools like credit cards or CD cases, which can scratch the windscreen. Remember, the idling rule does not apply on your private driveway, but it is strictly enforced on all public roads.
