Driving long distances in hot weather

When warm weather arrives, many of us start planning summer road trips. Depending on what route you take, you may find there are long distances between petrol stations and towns.

To help you have a safe trip, MotorHappy’s marketing director Barend Smit has a few tips for travelling long distances in hot weather.

“Most importantly, never leave children and pets in the car alone, even if you’re just popping into the shop for some snacks,” he cautioned. “It’s surprising how quickly a parked car can heat up in the sun. For example, if it’s 24 ºC outside, within 10 minutes your car can reach 38 ºC inside.” It’s also important to stay hydrated. Travel with enough extra water for you, your passengers, and any pets. That might mean several litres.

Before starting your journey, make sure your car is properly prepared by conducting all necessary vehicle inspections, like battery, fluid levels, and tyres – but with the hot weather in mind.

“Check to see when your next car service is due. Calculate all the kilometres you plan to drive and schedule a service if your car service is due before then,” advised Smit.

“Pay special attention to oil levels and coolant levels because hot weather driving puts heavy demand on your engine’s components.”

Before any road trip, it’s important to make sure your tyre pressure is at the right level.

“Tyre pressure and temperatures rise together,” Smit points out. “With high temperatures, the air inside your tyres expands and the air pressure temporarily increases. This could lead to a blowout. The heat from the roads can also cause the tyre to disintegrate. So, check your tyres carefully before, during, and after a hot summer road trip.”

If your engine overheats during your road trip, do not remove the cap while the engine is hot. Rather just raise the bonnet. Remember to make sure your hazard lights are on. Many road trips include a drive into the sunrise or the sunset when visibility is difficult. Make sure your wiper fluid is filled before starting your trip. Pack window cleaning fluid or a vinegar solution so you can manually clean the windscreen if necessary. Don’t forget to take your sunglasses!

Keep a well-stocked emergency kit in your car. It should include water, non-perishable foods, sunscreen, jumper cables, a torch with extra batteries, road warning triangles, basic hand tools, and a first aid kit. Remember to pack some cash for emergencies, a mobile charger and/or a power bank.

“Finally, plan your route carefully before starting your journey, taking note of petrol stations along the way where you can fill up and cool off. Even spaces such as shopping centers or supermarkets can provide quick relief from the sun or extreme heat,” concluded Smit.
