As January ushers in a cold snap across the UK, motorists are being reminded to stay vigilant when defrosting their vehicles. The common practice of leaving a car’s engine running and keys in the ignition while clearing icy windows – known as ‘frost jacking’ – may seem convenient, but it poses a significant risk of theft and could invalidate your insurance.

HPI, the leading vehicle history check and valuation specialists, are urging drivers not to fall for the temptation of leaving their car running unattended, especially with temperatures plunging and icy conditions gripping the country. Opportunistic thieves are always on the lookout for easy targets, and a running engine with keys left inside offers the perfect opportunity.

The Risks of Frost Jacking: Theft and Insurance Invalidations

Leaving your car unattended with the engine running is not just a theft risk – it could also invalidate your insurance. Most car insurance policies include a ‘keys in car’ exclusion clause, which means that if your vehicle is stolen under these circumstances, your insurance may not cover the loss.

Beyond the risk of theft, leaving your car running unattended also has legal consequences. The Road Vehicles (Construction and Use) Regulations 1986, along with Rule 123 of the Highway Code, make it illegal to leave a vehicle unattended with the engine running. Drivers caught in this situation could face fines between £20 and £80. Additionally, failing to clear ice from your windscreen properly before driving could result in a fine and three penalty points on your license.

Why Frost Jacking is So Tempting – But So Dangerous

During cold snaps like the one currently sweeping the UK, it’s tempting to start the engine and leave it running while you head back inside to warm up. However, the risk of theft is high, particularly in the early hours of the morning when visibility is low, and drivers are often in a rush to get going. Thieves are on the lookout for unattended cars, and all it takes is a few minutes for them to spot a running engine, jump in, and drive off.

HPI identifies 109 stolen cars every day, and winter months, especially January, see an uptick in opportunistic car crimes. As the icy conditions continue, it’s essential to take extra precautions to avoid becoming a victim.

Practical Tips to Avoid Frost Jacking in January

To help you safely defrost your vehicle while avoiding theft and legal issues, HPI recommends the following simple steps:

1. Use De-Icer: Apply de-icer generously to the windscreen and other icy areas, allowing it to penetrate the frost before scraping. This will make the process quicker and more efficient.
2. Cover the Windscreen: If you don’t have de-icer, try covering your windscreen with cardboard or a dry blanket the night before. This can prevent frost from forming and save you time in the morning.
3. Scrape While You Wait: After applying de-icer, stay with your car and scrape off the ice. This ensures your vehicle is attended at all times and not left vulnerable to theft.
4. Warm Air Method: Start your engine and set the heater to blow warm air onto the windscreen. This will help melt the ice from the inside while you scrape from the outside – but remember to stay with the car while doing this.
5. Check Wipers: Before turning on your car, check that the wipers aren’t frozen to the windscreen. If they are, gently lift them to avoid damaging the wiper motor.
6. Clear Snow and Ice: Remove any snow or ice from the roof and other surfaces of your car. This will prevent snow from sliding onto the windscreen while driving, which could reduce visibility and be dangerous.

Stay Safe and Stay Legal This January

Stacey Ward, Senior Data Director at HPI, commented: “As the UK continues to experience freezing temperatures this January, it’s more important than ever for drivers to take steps to protect their vehicles. Leaving a car running unattended is a major theft risk and could have serious legal and financial consequences. Not only could you lose your car, but you could also invalidate your insurance and face fines. Always stay with your vehicle while defrosting, and be aware of the legal implications of leaving your car running in public areas.”
