The Automobile Association has issued an urgent safety alert to British drivers as the nation experiences its first significant cold snap of the season. With temperatures plunging below freezing and weather warnings active across the country, the motoring organisation is emphasising proper techniques for removing ice from vehicles.
The Dangerous Defrosting Mistake You're Making
As Brits wake up to frozen windscreens during these frosty mornings, many are committing a critical error in their rush to clear ice. While most drivers understand that hot water can crack glass, the AA reveals that even lukewarm water poses serious risks to vehicle windscreens.
According to official AA guidance, glass expands rapidly when warm water touches it and contracts quickly as it cools in cold air. This flexing action can cause cracks to develop, particularly in screens that already have minor chips or damage.
The organisation also warns that using water of any temperature can create additional problems. Warm water freezes more rapidly than cold water, potentially forming an extra layer of ice on the windscreen. Spilled water can also create hazardous icy patches on the ground.
Comprehensive Safe Defrosting Guide
The AA has outlined a step-by-step procedure for safely clearing ice from vehicles. The process begins before starting your engine with a crucial check of your wiper controls.
Ensure your wipers are switched off before ignition to prevent damaging the wiper motor or tearing the rubber blades if they're frozen to the glass. Once confirmed, start the engine and direct warm air toward the windscreen using your car's heating system.
Activate your rear window heater and heated mirrors if your vehicle has these features. Using air conditioning can accelerate the defrosting process while preventing interior misting from developing.
Remain inside your vehicle while the engine runs and the frozen surfaces begin to thaw. Once the ice has softened, exit the car to brush away snow using a soft brush, paying particular attention to clearing the front grille and ensuring headlights are visible and functional.
Use a proper ice scraper and de-icer spray on all exterior windows. The AA emphasises that drivers should never begin their journey until every window is completely clear for maximum visibility and safety.
Severe Weather Conditions Prompt Warning
This urgent advice comes as the UK experiences its first significant winter weather, with temperatures dropping to -6.1°C in Cumbria, -5.8°C in Wales, and -4.8°C in parts of Scotland. The cold snap has triggered weather warnings across 47 regions, including a rare amber alert for snow.
With yellow and amber weather alerts declared nationwide, the AA aims to prevent both vehicle damage and potential accidents caused by improper defrosting techniques during this harsh winter period.
Summarising their recommendations, the AA stated: "Turn on the car heaters and the air-con, and use a proper brush or de-icer to scrape the frost off your frozen windscreen while you wait for the car to warm up."
