Britain is experiencing a growing challenge with potholes, a problem traditionally associated with winter but increasingly prevalent during the summer months due to rising temperatures. The ongoing deterioration of road surfaces is costing motorists an estimated £3.3 billion annually in vehicle repairs, with nearly 25% of drivers reporting damage to tyres, wheels, or suspension systems, according to data from Close Brothers Motor Finance.

Experts attribute this summer increase to extreme heat conditions. When road surface temperatures reach between 50°C and 60°C, bitumen—the binding material in asphalt—begins to soften and melt. This weakening of the road’s structure makes it more susceptible to disintegration under the weight of heavy vehicles. Additionally, a surge in domestic travel, partly influenced by wildfires in other parts of Europe, has raised traffic levels on UK roads, intensifying wear and tear.

For motorists, the consequences of hitting potholes can be significant, potentially causing tyre punctures, wheel damage, and problems with steering and suspension. The risks are even greater for cyclists and motorcyclists, for whom pothole impacts can be hazardous.

Motor trade advisers suggest several preventative tips to reduce damage. Maintaining proper tyre pressure is crucial, as adequately inflated tyres better absorb the shocks of pothole impacts, protecting vehicle components. However, overinflating tyres can increase the risk of blowouts, so pressure should remain within manufacturer recommendations.

Drivers are also encouraged to slow down when encountering potholes, but avoid harsh braking in these moments. Keeping tyres rolling helps distribute force more effectively, limiting damage. Visibility plays an important role, and using dipped headlights instead of full beams can improve the contrast that reveals potholes, especially in low-light or adverse weather conditions.

Following a pothole collision, motorists should stop safely to check for damage, watching for indicators like a sudden loss of tyre pressure, steering issues, vibrations, or unusual noises. Any suspected damage should be promptly inspected by a professional.

Although there is no specific legislation that explicitly addresses pothole claims, authorities have a legal responsibility to maintain safe roads. Motorists suffering damage may seek compensation by filing claims with the relevant bodies: local councils for minor roads and National Highways for motorways and most A roads. Collecting photographic evidence of the pothole—ideally with an object such as a ruler or coin to establish scale—and documenting vehicle damage can strengthen claims. Typically, to be considered a pothole, a defect must be at least 4 centimeters deep.

With forecasts indicating that UK summers may continue to experience above-average temperatures, the prevalence of potholes during the warmer months is expected to persist, underscoring the need for motorists and authorities alike to adapt to this evolving challenge.
