As temperatures in the UK continue to soar, with some areas reaching nearly 40°C in July, driving a Heavy Goods Vehicle (HGV) in such conditions presents unique challenges. Extreme heat can have significant effects on both the vehicle and the driver, making it crucial to take extra precautions to ensure safety. This article outlines several potential hazards of driving in hot weather and provides practical tips to stay safe on the road.

Tyre Safety

One of the most critical aspects of driving in hot weather is maintaining tyre safety. As temperatures rise, so does the air pressure inside the tyres. When road surfaces and tyres reach extreme temperatures, the performance of the tyres can be compromised. This can result in reduced grip and handling, and in extreme cases, tyres can blow out or even catch fire.

To mitigate these risks, it’s advisable to check your tyres every 100 miles when driving in hot conditions. Regularly monitoring tyre pressure and condition helps maintain optimal performance and reduces the risk of tyre-related incidents. Ensure that your tyres are properly inflated and in good condition before setting off on your journey, and be vigilant for any signs of wear or damage during the trip.

Brakes

While cold weather is often associated with brake issues, hot weather can be equally problematic. Brakes generate a significant amount of heat during use, and in high temperatures, this heat is slower to dissipate. This can lead to brakes becoming less effective, unpredictable, or even failing entirely.
To avoid brake-related issues in hot weather, ensure that your brake fluid is up-to-date and that your brake pads are in good condition. It’s also essential to leave ample space between your vehicle and others, allowing for more gradual braking. This reduces the strain on your brakes and decreases the likelihood of overheating.

Awareness of Other Motorists

Hot weather often coincides with holiday season, which means increased traffic and a higher number of drivers who may not be as experienced or alert as professional HGV drivers. These motorists may be unfamiliar with their routes, fatigued from long drives, or less cautious due to the holiday atmosphere. They may also be prone to making sudden or unsafe manoeuvres.
As an HGV driver, it’s important to remain extra vigilant during this time. Give other road users plenty of space and anticipate that they might make unexpected moves. Patience and caution are key to avoiding accidents and ensuring that everyone on the road remains safe.

Sunburn Prevention

The term “trucker’s arm” is often used humorously to describe the sunburn that drivers can get on their exposed arm while driving with the window open. However, sunburn is no laughing matter; it can cause severe pain in the short term and increase the risk of skin cancer in the long term.
To protect yourself, make sure to cover up during the hottest parts of the day. Wearing long sleeves made from light, breathable fabric can help shield your skin from the sun. Additionally, apply a high-SPF sun cream generously and regularly, especially on areas of skin exposed to direct sunlight.

Dressing for the Heat

While HGV drivers typically wear uniforms or specific workwear, it’s important to adapt your clothing for the hot weather. Wearing heavy rain gear or high-visibility jackets may be necessary in some situations, but in extreme heat, these can cause discomfort and even lead to overheating.
Check with your employer to see if there are any adjustments to the dress code during hot weather. Many hauliers allow for lighter clothing, such as smart shorts and short-sleeved shirts, which can help keep you cool while still maintaining a professional appearance.

Eye Protection

Bright sunlight and reflections from the road or other vehicles can significantly impair your visibility, increasing the risk of accidents. This is especially true during sunrise and sunset when the sun is low in the sky and can create blinding glare.
To protect your eyes and maintain clear vision, always carry a pair of sunglasses, preferably with polarised lenses. These lenses reduce glare and enhance contrast, making it easier to see the road ahead. Additionally, make full use of the sun visors in your cab to block out direct sunlight.

Staying Hydrated

Staying hydrated is crucial when driving in hot weather. Dehydration can lead to fatigue, confusion, and muscle cramps, all of which can impair your ability to operate an HGV safely. Health authorities typically recommend drinking at least 2 litres of water per day, but in hot weather, you will likely need more.
Make it a habit to drink water regularly throughout your journey. Keep extra bottles of water in your cab, and take advantage of breaks to refill and stay hydrated. Staying well-hydrated helps maintain concentration and alertness, which are essential for safe driving.

Utilising Air Conditioning

If your vehicle is equipped with air conditioning, make full use of it to keep the cab cool and reduce humidity. The Highway Code even recommends using a blast of cold air to help you stay alert and avoid drowsiness. However, it’s important to be aware that using air conditioning or driving with the windows down can impact fuel consumption.

If your vehicle doesn’t have air conditioning, driving with the window open can provide some relief, although it may cause air to whip around the cab. Weigh the benefits of staying cool against the potential increase in fuel usage, and choose the option that best suits your situation.

Maximising Breaks

Driving in hot weather can be physically exhausting, as your body works harder to stay cool. This makes it even more important to take regular breaks. Use these breaks to step out of the cab, cool down, and recharge. If you’re at a truck stop, consider taking a cool shower to lower your body temperature.

During breaks, take the opportunity to refill your water bottles, reapply sun cream, and rest in the shade. These small actions can make a big difference in your comfort and safety during long drives in hot weather.

Conclusion

Driving an HGV in hot weather presents a unique set of challenges, but with the right precautions, you can minimise the risks. By paying close attention to tyre safety, brakes, and other motorists, as well as taking care of your own health and comfort, you can ensure that your journey is safe and stress-free. Always remember that staying cool, hydrated, and alert is key to navigating the roads during the summer months.
