Drivers are being warned not to be caught out by the hot weather, which could see a “short, sharp spike” in breakdowns in the UK.  

The RAC said it’s expecting the number of breakdowns to increase, especially in central and southern parts of the UK

As the Met Office forecasts a steep rise in temperatures over the next couple of days and the UK Health Security Agency (UKHSA) issues a heat-health alert, the RAC said it’s expecting the number of breakdowns to increase, especially in central and southern parts of the UK.   

Hot weather can cause havoc for vehicle components and the RAC is advising drivers to check their cars’ oil and coolant levels as soon as they possibly can, particularly if they have a long trip planned in the hottest part of the day, and to access its guide to avoiding breakdowns during hot weather.

Spokesperson Rod Dennis added: “Drivers should also stay hydrated which has been shown to have a positive effect on their concentration levels. Passengers should also be kept as cool and comfortable as possible so carry plenty of water and plan in sufficient breaks to avoid an already hot car becoming even more heated.”  

Meanwhile, the AA has warned drivers not to lock children or pets in cars as the temperatures soar. Last summer, its patrols rescued an average of two children and two pets a day after they had been locked in vehicles, resulting in avoidable stress for parents and pet owners.

It’s also advising drivers to carry plenty of drinking water and use window blinds to help shield children and passengers, and sunglasses to reduce glare.

Sean Sidley, AA patrol of the year, said: “Checking your car before you travel can provide peace of mind and leave you free to enjoy the weather. We often advise drivers to be prepared in cold weather, but it is equally important in hot conditions. Part of your checks should include making sure you have sufficient breakdown cover in place. If you break down on a motorway National Highways can charge upwards of £150 to move you to safety. Once in a safe location, your vehicle will still need to be repaired or recovered.

“If it gets sticky on the roads there’s nothing worse than being stuck in a jam with the mercury rising, so make sure you carry plenty of water – at least a litre per person – and sufficient fuel, or if you’re driving an electric vehicle – make sure you have plenty of charge so you can use the air-conditioning when needed. It only takes one incident to cause tailbacks, so keep tuned to local traffic reports; and plan in sufficient stops – frequent short ones are better than one long stop.”

Hot weather can also highlight faults such as seized cooling fan motors which can contribute to engine damage if left undetected. The AA advises that the most effective way of temporarily dealing with an overheating car is to turn the heater up full and the air conditioning on. If the worst does happen, try to stop somewhere safe then follow the advice of your breakdown provider.
