Is hitting road debris considered an at-fault accident?
In the UK, hitting debris on the road is usually treated as your fault—unless it’s clear that another party caused or failed to remove it.
Every year, thousands of motorists find themselves facing unexpected damage from objects left or thrown onto roads. Whether it’s a loose tyre tread, a fallen branch, or debris from roadworks, the question many drivers ask afterwards is the same: will this be treated as my fault?
Understanding how insurers and the law define “fault” in these scenarios is crucial, because the answer directly impacts whether your claim is paid, your no-claims bonus is protected, and your future premiums go up. In this article, we’ll break down when hitting road debris is considered at fault, when it might not be, and what steps you should take if it happens to you.
What does “at-fault” mean in UK driving accidents?
An at-fault accident in the UK is one where your insurer must pay out because you’re considered responsible, even partly, for the damage.
This doesn’t always mean you broke the law. Fault in insurance terms is about liability, not criminal guilt. For example, if you hit a parked car while reversing, you’re clearly at fault. But even if you hit a fallen tree branch, insurers may still classify it as “at-fault” because no third party can be held liable.
That distinction is important. Police and courts deal with blame for legal offences, but insurers are primarily interested in who covers the cost of repairs. If no one else can reasonably be held accountable, the cost comes back to your policy.

In most cases, hitting road debris is treated as an at-fault accident because insurers see it as the driver’s responsibility to avoid hazards.
For example, if you strike a tyre tread, fallen branch, or debris lost from another vehicle, insurers usually argue that you could have slowed down or safely avoided it. Even when the debris isn’t your fault, you may still be deemed liable unless you can clearly prove another party’s wrongdoing.
Collecting official data on debris-specific collisions is tricky—but the scale of vehicle-related road debris isn’t small. A landmark U.S. study once linked it to about 25,000 accidents and nearly 100 deaths a year. While the UK figure is lower, the message is clear: debris—however mundane it seems—poses a serious hazard.
The RAC reported 9,439 pothole-related breakdowns in just the first three months of 2025 — more than double the previous quarter. With over 1 million potholes estimated on UK roads, debris hazards are far from rare, which explains why insurers take a strict approach to liability.
Because it’s difficult to trace responsibility back to a third party, these incidents are often classified as at-fault. That means your no-claims discount could be affected and your premiums might go up even after something as simple as running over debris.
When might It not be your fault?
If another driver’s negligence directly causes the debris hazard, you may not be classed as at fault — provided you can prove it.
For instance, if a lorry’s unsecured load falls into your path and damages your car, liability could rest with the haulage company or driver. Similarly, if roadworks leave unsafe debris in the carriageway, the local authority or contractor might be responsible.
The challenge is evidence. Without dashcam footage, witness statements, or police reports linking the debris to a specific third party, insurers often default to treating the claim as at-fault. This is why dashcams are increasingly popular in the UK: they provide the proof insurers need to shift liability away from the driver.
How do insurers handle road debris claims?
Most UK insurers treat hitting road debris as an at-fault claim unless there is clear evidence another party caused the hazard.
That’s because insurance companies work on the principle of recoverability. If no one else can be held liable, your insurer pays out, but you take the hit on your no-claims bonus and may face higher premiums at renewal.
If, however, you can prove another driver was responsible — for example, a poorly secured load falling in front of you — your insurer may try to recover costs from them or their insurer. In these cases, your claim could be reclassified as non-fault.
Policy type also matters. Comprehensive cover typically protects against debris damage, whereas third-party policies don’t usually cover repair costs. Some insurers also view debris-related incidents differently depending on whether the damage was unavoidable or partly due to driver error, like speeding on an unlit road.
What evidence do you need to prove it wasn’t your fault?
To prove a road debris incident wasn’t your fault, you’ll need solid evidence linking the hazard to another party.
Dashcam footage is one of the strongest forms of proof. If your camera captures debris falling directly from another vehicle, your insurer can pursue them for liability. Witness statements also help, especially if they confirm how the hazard appeared.
Police reports carry weight too. If officers attend the scene and note that debris came from a particular vehicle or was left by roadworks, this can shift responsibility away from you. Even photographs of the scene — showing debris, skid marks, or nearby construction work — can strengthen your case.
Without this evidence, insurers are more likely to default to treating the accident as your fault, regardless of circumstances.
Does your policy cover road debris damage?
Yes — but only if you have comprehensive cover. Third-party only or third-party, fire and theft policies won’t usually pay for damage caused by road debris.
Comprehensive car insurance generally covers accidental damage, which includes hitting debris. This could mean anything from repairing bodywork dented by a fallen object to replacing tyres blown out by sharp debris.
According to the RAC, the average repair bill for pothole and road surface damage is around £460 — a cost many drivers would struggle to cover without comprehensive insurance. However, even with cover, you’ll likely need to pay your excess, and your no-claims discount may be affected if the claim is recorded as at-fault.
Third-party policies are more limited. If you only hold this level of cover, you’ll usually have to pay for repairs yourself unless you can recover costs from a liable third party — which, without evidence, can be extremely difficult.
Some insurers also offer optional add-ons like windscreen cover or breakdown assistance that can help if debris causes specific types of damage, but these aren’t standard across all policies.
Tips to reduce the risk of hitting road debris
You can reduce the risk of hitting road debris by slowing down, keeping your distance, and staying alert — especially on motorways and rural roads.
Leaving extra space gives you more time to react if a vehicle ahead suddenly swerves or sheds cargo. On faster roads, this buffer zone can be the difference between avoiding a hazard and making impact.
Scan the road ahead rather than just the car in front. Spotting objects early, whether it’s tyre fragments or a pallet on the tarmac, increases your options for safe avoidance.
Driving at night requires more caution. Reduced visibility makes debris harder to detect, so lower your speed on unlit stretches and use full beams when safe to do so.
Finally, be especially wary behind lorries, skip vans, or vehicles carrying loads. Poorly secured items are a major cause of debris on UK roads, and giving these vehicles a wide berth is one of the simplest ways to protect yourself.
Final thoughts
Hitting road debris in the UK is a grey area when it comes to fault. Unless you can clearly show that another party was responsible — for example, debris falling from a poorly secured lorry — insurers will often record the accident as at-fault. That’s why evidence such as dashcam footage, police reports, or witness statements can make all the difference.
While comprehensive cover usually protects against debris damage, excess payments and potential no-claims losses still apply. Prevention, through careful driving and awareness, remains your best defence.
If you want to be prepared for the unexpected, reviewing your car insurance policy with SimplyQuote ensures you’ve got the right level of cover in place. That way, whether it’s debris on the motorway or an unavoidable hazard in town, you’re not left footing the entire bill.
