Heating mistake could see drivers ‘hit with fine and penalty points’

Motorists are being warned about the risks of drowsiness while driving in chilly weather. Experts are highlighting that using a car’s heating system can lead to fatigue on the roads as drivers navigate winter conditions.

While some individuals turn to social media for advice on what temperature to set their car at, it’s crucial to heed expert guidance. Car insurance specialists at Tiger.co.uk recommend drivers maintain a well-regulated temperature inside the vehicle to avoid breaching The Highway Code.

Prolonged use of the heater can raise body temperature and reduce oxygen levels in the car, leading to fatigue and a false sense of comfort, which can impair reaction times and concentration.

Although The Highway Code doesn’t specifically list drowsy driving as an offence, it can be classified as careless or dangerous driving, potentially resulting in an unlimited motoring fine and three to 11 penalty points on your driver’s licence.

Unlike drug or alcohol-related offences, police cannot test a driver for fatigue, suggesting such incidents are likely underreported. It’s estimated that fatigue contributes to between 10% and 20% of all road accidents globally.

Driving while fatigued can hinder reflexes and decision-making to the same extent as driving under the influence of alcohol, making it equally perilous. Therefore, it’s vital for drivers to pay attention to the temperature and ventilation inside their vehicle.

Drivers are advised to maintain a comfortable cabin temperature, ideally between 19°C and 22°C, and use the ventilation system to keep fresh air circulating rather than relying on air recirculation, which can quickly make the interior stuffy.

Regular breaks to stretch and get some fresh air are also essential during long journeys.

Ian Wilson, Managing Director and car insurance expert at Tiger.co.uk, said: “In winter, many of us blast on the heating as soon as we get into the car to help combat the chill, but too much heat, especially with the air recirculating, can make you feel drowsy far quicker than you realise.

“It might feel cosy, but that warm, still air can reduce oxygen levels and slow your reflexes, which is dangerous behind the wheel.

“Keeping the temperature balanced, cracking a window for ventilation, and taking breaks on longer journeys are simple ways to help stay alert and safe this winter.”

Expert tips for staying warm in your vehicle without risking sleepiness

1. Keep temperatures reasonable

Your car’s interior should be comfortable, but there’s no need to have the heating turned up to the maximum. Aim for approximately 19°C to 22°C – warm enough for comfort without inducing drowsiness.

2. Use air conditioning briefly

While it may sound counterintuitive to activate air conditioning during winter, running it momentarily can help decrease humidity and enhance air circulation, preventing the cabin from becoming stifling and helping ward off sleepiness.

3. Crack windows open slightly open the windows to allow fresh air in

This maintains oxygen levels and helps you stay alert.

4. Choose multiple thin layers

Think about your attire so you’re not solely dependent on the car’s heating system. Keep in mind that bulky jackets can limit movement and disrupt seat belt function in case of an accident.

Instead, opt for several thinner layers that can be easily added or removed as required.

5. Regular breaks are key

For lengthy trips, make sure to stop frequently to stretch your legs, breathe in some fresh air and refocus. Even a brief pause can enhance alertness, contributing to safer driving.
