The UK is preparing for an absolute scorcher. With temperatures forecast to climb during a four-day extreme heatwave, many of us will be looking forward to a bit of summer sunshine. However, if you are someone who has to drive for work, extreme heat introduces a whole host of challenges that go far beyond just feeling sweaty and uncomfortable behind the wheel.
Whether you are managing a busy commercial fleet or driving your own car for business, staying safe on the motorway is a top priority. Spending hours on the road in intense heat is hard on your body and your vehicle.
Our comprehensive guide outlines why extreme hot weather is so risky for business drivers, how to prepare, and how Fleet Service GB is able to streamline your operations with proactive maintenance, complete driver training, and bespoke driver wellbeing workshops.
What Are the Main Dangers of Business Driving in a UK Heatwave?
Driving during a UK heatwave introduces four major hazards for business drivers: slower reaction times (up to 20% slower at 35°C), rapid concentration loss due to dehydration, blinding road glare, and mechanical failures like tyre blowouts caused by expanding hot air. These combined factors significantly increase accident rates.
When you drive for a living, you do not always have the luxury of avoiding the roads during peak temperatures. Here are some of the primary risks you must prepare for:
- Slower Reaction Times: Research shows that driving in temperatures around 35°C can slow your reaction times by up to 20% compared to cooler conditions. This significantly increases your stopping distances and makes reacting to sudden hazards much harder.
- Dehydration and Concentration Loss: Just a 2% drop in hydration can lead to a massive 20% loss in mental focus. Dehydration sneaks up fast, causing fatigue, headaches, and poor decision-making on busy A-roads.
- Glare and Blind Spots: Strong summer sunshine creates intense glare, making it highly difficult to spot vulnerable road users like cyclists, motorcyclists, and pedestrians.
- Vehicle Breakdowns: Extreme temperatures put serious strain on your cooling systems, car batteries, and tyres. Hot tarmac causes tyre air to expand, which dramatically increases the risk of a high-speed blowout.
Before setting off, it is always a sensible idea to check the Met Office for real-time weather warnings to help you plan safer routes. Read more about these risks in our previous article on driving during heatwaves.
How Can Drivers Prepare for Work Trips in Extreme Heat?
To stay safe on work trips during a heatwave, drivers should release trapped cabin heat before starting, wear lightweight clothes and sturdy shoes, drink plenty of water, and plan rest breaks every two hours. Ensuring the vehicle’s coolant, oil, and tyres are checked is also vital.
With a bit of planning, you can easily minimise the risks of business driving in summer. Use this quick, actionable checklist before you start your engine:
How to Cool Down Your Vehicle Fast
Do not just jump in and instantly blast your air conditioning. Instead, open all your vehicle’s doors for about 30 seconds before setting off. This releases the trapped hot air first, reducing the strain on your air-con system and cooling the cabin down much faster.
What is the Best Gear to Wear When Driving?
- Opt for loose, lightweight, and breathable clothing to stay cool.
- Avoid flip-flops or sandals. They are dangerous for driving because they can easily slip off or jam under the pedals. Sturdy, comfortable shoes are a must.
- Use UV-blocking sunglasses to combat glare, but avoid category 4 lenses as they are too dark for safe driving.
How to Stay Hydrated Behind the Wheel
Keep plenty of fresh water within arm’s reach. A great trick is to freeze a couple of water bottles overnight so you can sip ice-cold water throughout your day. According to official NHS hydration advice, you should avoid excessive caffeine and sugary energy drinks, as they actually accelerate dehydration.
When and How Often Should You Take Rest Breaks?
Plan to stop at least every two hours to stretch, cool down, and rest in a shaded spot. If you start to feel fatigued, dizzy, or lose concentration, pull over in a safe place immediately.

FAQs About Driving in a Heatwave
Is it illegal to drive in a heatwave in the UK?
No, driving in a UK heatwave is not illegal. However, you can face a £5,000 fine and points on your licence for ‘careless driving’ if you drive while dangerously dehydrated, severely fatigued, or wearing unsafe footwear like loose flip-flops that slip off the pedals.
How do you stop a vehicle from overheating in hot weather?
To prevent your vehicle from overheating, check your engine coolant and oil levels before starting. If the engine temperature rises while driving, turn off the air conditioning, turn the cabin heater on to max to draw heat away, pull over safely, and rest for 30 minutes.
Can my employer make me drive in extreme heat?
Yes, UK employers can require you to drive in a heatwave, but they must meet their legal duty of care. If a company vehicle lacks functioning air-con or requires long driving shifts without breaks in severe heat, employers must intervene to make it safe.
