The UK is bracing itself for a potentially catastrophic rise in vehicle breakdowns this summer, as record-breaking heatwaves threaten to push motorists' vehicles to their limits. According to the RAC, there could be a 10% increase in call-outs compared to previous years, driven primarily by the challenging conditions posed by high temperatures.
Data from the motoring organisation indicates that common issues during hot weather include battery failures, engine overheating, and tyre problems. Batteries already under strain can struggle in extreme heat, while engines are more prone to overheating if coolant levels are low or cooling systems are compromised. Under-inflated tyres are also at a higher risk of blowouts as temperatures rise, causing friction and pressure within the tyre.
To mitigate these risks, the RAC is urging drivers to undertake essential preventative checks before embarking on journeys, especially longer ones. Key advice includes ensuring coolant levels are topped up, checking tyre pressures and condition, verifying oil levels, and inspecting the battery for any signs of weakness. These simple checks can significantly reduce the likelihood of a roadside breakdown.
The context for this warning is the Met Office's ongoing assessment of climate change impacts on the UK, which points to a clear trend of hotter, drier summers and more extreme heat events. While specific Met Office warnings for upcoming heatwaves are yet to be issued, the long-term forecast suggests an increased probability of such conditions. During previous heatwaves, temperatures across England have often exceeded 30 degrees Celsius, with parts of Wales, Scotland, and Northern Ireland also experiencing significant heat.
For those planning journeys across the UK, particular attention should be paid to regional forecasts. In England, urban areas and the South East are often most susceptible to high temperatures. Scotland's central belt and eastern regions can also experience significant heat, while parts of Wales, particularly the south, and Northern Ireland are not immune to the impacts of heatwaves. Carrying plenty of water, planning routes to avoid peak heat times, and ensuring mobile phones are charged are practical steps recommended for all drivers.
The implications of increased breakdowns extend beyond individual inconvenience, potentially leading to greater congestion on roads and increased demand on emergency services. The RAC's proactive advice aims to minimise these disruptions and ensure safer travel for everyone during the summer months.
