Driving in the Sun - How to Prepare Your Truck or Van for Hot Weather

Summer might mean blue skies and lighter evenings, but for commercial drivers, it also brings unique challenges on the road. Whether you're in a van or a truck, preparing properly for sunny conditions can make a big difference to your safety, comfort, and vehicle performance.

Here’s what you can do to get ready for sunny weather:

1. Stay Hydrated

It might sound basic, but dehydration leads to fatigue, slower reactions, and poor concentration. Always have a bottle of water with you and take regular breaks to top up.

2. Check Tyres Before You Set Off

Hot roads = increased tyre pressure. Make sure tyres are at the correct pressure and look out for any cracks or uneven wear. Blowouts are more common in the heat, especially with heavier loads.

3. Keep Sunglasses Handy

Sun glare can reduce visibility and reaction times – especially when the sun is low in the sky. A pair of polarised sunglasses will help cut glare and keep your eyes relaxed over long distances.

4. Use Sun Visors & Windscreen Shades

Lower your sun visor when needed, and if you’re parked up during a break, use a reflective screen to keep the cab cooler. It’ll make a big difference when you get back in.

5. Maintain Air Con & Ventilation

If your vehicle has air conditioning, make sure it’s serviced and working properly. A hot, stuffy cab can lead to discomfort and loss of focus.

6. Watch for Heat Impact on Braking

Heat can affect your vehicle’s braking performance – especially on long descents or when carrying heavy loads. Use engine braking where possible and allow extra space for stopping.

7. Protect Yourself from the Sun

Even through glass, you can still get sunburnt during long drives. Apply sunscreen to exposed areas, especially your arms and face.

8. Be Extra Alert Around Vulnerable Road Users

More people are out walking and cycling in the sun. Glare, reflections, and increased foot traffic mean you need to be especially careful at junctions, crossings, and in built-up areas.

9. Plan for Breakdowns

Hot weather can be tough on engines. Make sure you’ve got water, a charged phone, and high-vis in case you break down somewhere remote or busy.

10. Take Breaks

It’s tempting to power through your day, but hot weather increases fatigue. Take your proper rest stops, and try to find a shaded or air-conditioned spot to cool off.
