Failure to use air conditioning can result in fines up to £5,000
Drivers are being warned that not using air conditioning or failing to ventilate their vehicles during hot weather could lead to fines of up to £5,000. With heatwaves affecting the UK, cars can quickly become excessively hot, and poor ventilation may cause drivers to lose concentration or control, even momentarily, which can be classed as careless driving.
Penalties for careless driving start at £1,000 and can increase to £5,000 along with nine penalty points if the incident is serious. The warning comes from experts at BigWantsYourCar.com, who urge motorists to take the summer heat seriously.
Highway Code rule 237 addresses vehicle ventilation
Rule 237 of the Highway Code states: "Keep your vehicle well ventilated to avoid drowsiness. Be aware that the road surface may become soft or if it rains after a dry spell it may become slippery. These conditions could affect your steering and braking. If you are dazzled by bright sunlight, slow down and if necessary, stop."
While this rule may not be widely known, its purpose is to ensure drivers remain alert and in control. Without proper airflow, a car's interior can overheat, leading to driver fatigue, slower reaction times, and poor decision-making.
Expert advice on financial and safety risks
“Many drivers don’t realise that something as simple as skipping the air con or not cracking a window in hot weather could actually breach the Highway Code,” explains a car expert at BigWantsYourCar.com. “If overheating or fatigue causes a lapse in judgement or results in an accident, you could be facing serious legal and financial consequences, including fines, points, or even prosecution.”
“From a safety point of view, keeping your car cool and comfortable is essential,” adds the expert. “But it also makes good financial sense. An avoidable fine or a bump caused by drowsiness can cost money and damage your car’s resale value.”
Poor ventilation can affect car value and insurance
Poor ventilation can hurt a driver's wallet in multiple ways. Accidents, even minor ones, can negatively impact a vehicle's condition, insurance history, and market value. “Cars with a clean driving history and minimal wear and tear always achieve a higher valuation,” say the expert. “But if you’ve been involved in a careless driving incident or your vehicle’s condition has suffered from long-term neglect, it can seriously dent its worth.”
Drivers are advised to ensure their air conditioning is functioning properly and to keep windows open when necessary to maintain airflow and avoid drowsiness behind the wheel.
