Potholes have become an increasingly common problem on UK roads, causing frustration for drivers, cyclists, and motorcyclists alike. From damaged tyres and cracked alloy wheels to suspension issues and unsafe driving conditions, potholes can create serious problems for both vehicles and road users.
But why are there now so many potholes appearing across the UK, and what can drivers do to reduce the risk of damage?

What causes potholes?
Potholes form when water enters small cracks in the road surface.
Over time, traffic weakens the road material, creating tiny fractures. When water seeps into these cracks and temperatures drop, the water freezes and expands, making the cracks larger.
Once the ice melts, the empty spaces beneath the road surface weaken the structure even further. As vehicles drive over the weakened area, the road surface collapses and a pothole forms.
Existing potholes also continue to grow because water washes away loose material around the edges, making the damage larger over time.
Heavy vehicles such as buses, vans, and lorries can accelerate this deterioration due to the extra weight placed on weakened road surfaces.
Why UK potholes seem to be getting worse
Several factors have contributed to the rise in potholes across UK roads, including:
- Increased traffic volumes
- Heavier modern vehicles
- Extreme weather changes
- Freeze-thaw winter conditions
- Ageing road infrastructure
- Delayed road maintenance
Periods of severe cold weather followed by rain can be especially damaging to road surfaces. Rapid temperature changes allow water to repeatedly freeze and thaw inside road cracks, speeding up deterioration.
As traffic levels continue to increase, roads face greater strain than ever before, particularly in urban areas and on heavily used routes.
How potholes can damage your car
Driving through potholes can cause a range of problems for your vehicle, including:
- Tyre punctures
- Cracked or bent alloy wheels
- Suspension damage
- Steering alignment issues
- Shock absorber wear
- Tracking problems
In severe cases, pothole damage can lead to expensive repair bills, especially if suspension or wheel components are affected.
Motorcyclists and cyclists can face even greater safety risks when encountering deep potholes unexpectedly.
How to avoid pothole damage
While it’s impossible to avoid every pothole, there are several ways to reduce the risk of damaging your vehicle.
Keep your tyres properly inflated
Correct tyre pressure helps absorb impacts more effectively and reduces the chance of tyre sidewall damage or wheel deformation.
Underinflated tyres are more vulnerable to pothole damage, so checking tyre pressures regularly is important.
Slow down safely
Hitting a pothole at high speed increases the force of impact and the likelihood of damage.
Reducing your speed when driving on poor road surfaces can help minimise the impact on your tyres, wheels, and suspension.
Avoid braking directly over potholes
Heavy braking transfers additional weight onto the front suspension, increasing the force applied when the wheel hits the pothole.
If it’s safe to do so, slow down before reaching the pothole rather than braking sharply as you hit it.
Stay alert and leave space
Keeping a safe distance from the vehicle in front improves visibility and gives you more time to spot potholes ahead.
Driving cautiously also allows you to avoid sudden swerving, which could create additional safety risks.
Final thoughts
Potholes remain one of the most frustrating issues facing UK drivers, and worsening road conditions continue to increase the risk of vehicle damage and repair costs.
While weather conditions and traffic levels play a major role in pothole formation, drivers can still help protect their vehicles through cautious driving, regular tyre checks, and staying alert on damaged roads.
