As the climate grows warmer and heatwaves become more prevalent, it is increasingly important for motorists to adjust their habits to ensure safe and comfortable travel during hot weather. High temperatures can create challenges so a degree of preparation and awareness can go a long way towards avoiding breakdowns, discomfort, or potentially hazardous situations.

Before embarking on a summer journey, it is advisable to check vehicles thoroughly. Hot conditions place additional strain on mechanical systems, making it essential to check fluid levels – engine coolant, oil, brake fluid and windscreen washer fluid. Coolant is especially critical, as low levels can lead to engine overheating, particularly in slow-moving traffic where airflow through the radiator is limited. Tyres should be regularly inspected for cracks or wear as high temperatures can increase internal pressure and exacerbate any existing damage, while tyre pressures should be adjusted according to the vehicle’s load. Similarly, windscreen chips or scratches can deteriorate under strong sunlight, potentially impairing visibility or developing into cracks.

Planning a journey carefully is equally important in hot conditions. Checking weather forecasts, traffic reports and potential delays enables drivers to avoid travelling during the hottest parts of the day if possible. Allowing ample time for a journey and scheduling regular breaks is essential, particularly for longer trips. Fatigue can set in more quickly in high temperatures, and the drowsiness associated with heat presents a genuine hazard. Drivers should aim to be well-rested before travelling, choose light, comfortable clothing, and avoid heavy meals or alcohol beforehand.

Within the vehicle, maintaining a comfortable temperature is vital. Air conditioning, where fitted, can help keep cabin temperatures manageable, although it does consume additional fuel, so drivers should monitor fuel levels carefully. For vehicles without air conditioning, opening multiple windows can improve airflow and reduce heat build-up, though at higher speeds this can increase aerodynamic drag and fuel consumption. Parking in shaded areas or using reflective sunshades can help reduce interior temperatures significantly, avoiding the discomfort of an overheated cabin.

Hydration is particularly important. Motorists are advised to carry sufficient drinking water for all occupants, including pets. Keeping a small summer kit in the vehicle – water, snacks, sun cream, hats, sunglasses and any necessary medication – can prove invaluable in the event of delays or a breakdown. If a vehicle begins to overheat, it’s crucial to pull over safely and allow the engine to cool before attempting to check fluid levels or top up the radiator. A radiator cap should never be removed while the engine is hot.

Bright sunlight can also create significant visibility issues. Glare reflecting from windscreens, dashboards or other vehicles can be dazzling, so it’s advisable to keep a good pair of sunglasses in the vehicle and to maintain a clean windscreen. Sun visors can help reduce glare when the sun is low, and modern removable sunshades are especially effective for shielding passengers in the rear seats from heat and bright light.

Modern vehicles are engineered to cope with a wide range of temperatures, and with sensible preparation and cautious driving, motorists can keep both their vehicles and themselves cool, comfortable and secure. Taking the appropriate precautions will help ensure that journeys remain safe and stress-free.
