Pothole Damage to Commercial Vehicles: What Drivers Should Check After a Hot Summer

Pothole damage to commercial vehicles may become more common after a hot summer, as heat and ultraviolet exposure leave already weak road surfaces more brittle. For HGV, van, tipper and mixer drivers, one hard impact can mean tyre or wheel damage, a damaged suspension, a safety concern or a vehicle off the road during a delivery.

The RAC warned on 16 September 2026 that prolonged heat can speed up the breakdown of asphalt. The concern is not limited to what drivers can see today: cracks may open further when rain gets in, and traffic can turn a weakened patch into a more serious defect. That makes the next few weeks a sensible point to tighten everyday checks and make sure drivers know what to do after an impact.

 

Why pothole damage to commercial vehicles can rise after heat

Potholes are often associated with winter. Cold and water still matter, but prolonged summer heat can also affect the binder that holds road materials together. The surface can become harder and less flexible, then crack as temperatures change. Once water reaches those cracks, passing traffic helps break away the surrounding material.

The Met Office has described summer 2026 as exceptional, with 33 days above 30°C and an average temperature 1.9°C above the long-term average. That does not mean every defect was caused by heat, but drivers should expect conditions to change quickly where a surface was already worn, patched or carrying heavy traffic.

For commercial vehicles, vehicle weight and daily mileage can make the consequences more expensive. A pothole strike may affect a tyre, wheel, tracking, steering or suspension. The first sign may be a vibration, a pull to one side, unusual steering feel or a new noise rather than an obvious puncture.

 

What drivers should look for on the road

Good observation gives a driver more time to reduce speed smoothly and keep a safe line. Leave enough distance to see beyond the vehicle in front, especially after rain when standing water can hide a defect. Watch for patched areas, broken edges, loose material and vehicles moving suddenly to avoid a hole.

Avoid a last-second swerve if there is traffic, a cyclist, a pedestrian or another hazard beside you. A controlled reduction in speed is usually easier to manage than a sharp change of direction, but drivers should never put anyone at risk to avoid a pothole.

After a difficult route or noticeable impact, check the tyres, wheels, steering feel and warning lights at the next safe stop. This can identify a problem before the next load, but it does not replace a competent inspection where damage is suspected.

 

If a vehicle hits a pothole

The priority is to get to a safe place. Do not stop in a live lane or on a motorway hard shoulder unless it is an emergency and the vehicle cannot be moved safely. Do not ask a driver to walk back along a carriageway to photograph the defect.

Once safe, keep a clear record. It may help with a repair decision, insurer notification, fleet review or claim against the highway authority, although it cannot guarantee any particular outcome.

 

• Note the date, time, road, direction of travel, lane and nearest identifiable location.
• Record what happened to the vehicle and any warning signs, vibration, steering change or loss of pressure.
• Take photographs of the damage and road condition only from a safe place, without entering a carriageway.
• Keep dashcam footage, driver notes, witness details, recovery records and repair estimates together.
• Report the defect to the right highway authority. The official reporting service directs drivers to the relevant council in England and Wales, or the national roads body where it manages the motorway or A road; Scotland and Northern Ireland use separate routes.

 

Where insurance and liability questions begin

If the vehicle has accidental damage, a motor policy may be relevant, but the response depends on the policy wording, excess, circumstances and the evidence available. Reporting a loss promptly and following the insurer's instructions is important. A repair invoice on its own may not explain when, where or how the damage happened.

A separate approach is to ask the authority responsible for the road to consider the damage. That is not an automatic route to compensation. The authority may look at its inspection and repair records, whether it knew or should have known about the defect, the road location and the circumstances of the incident. Use the correct authority and keep copies of reports and correspondence.

For an operator, the insurance question is wider than the damaged part. Check how a vehicle being off the road could affect deliveries, customer commitments, recovery, substitute vehicles and goods in transit. Those consequences do not all sit under one policy, and cover depends on the wording and circumstances. A review of your HGV & Truck Insurance or Tipper Mixer Insurance can help identify where the motor, liability and operational questions meet.

 

Use the warning as a fleet check

Managers can make the response easier by giving drivers a simple reporting route and asking for the same information after each significant impact. Check that maintenance records capture tyre, wheel, steering and suspension findings, and that vehicle use still matches the insurance submission.

The aim is to reduce avoidable injury and damage, spot defects early, and keep a reliable record when a vehicle or delivery is affected. That matters when a fleet is covering high mileage on roads that may deteriorate further as the seasons change.
