What if the other driver denies the accident was their fault?

6 min readUpdated Aug 2026

A denial does not mean your claim is over. It means fault has to be proven rather than assumed. Liability is often established using witnesses, dashcam or CCTV, the police report, vehicle damage, and sometimes expert reconstruction. Insurers sometimes wrongly blame riders, and a specialist solicitor can push back. This is general information, not legal advice, and no outcome can be guaranteed.

A denial is not the end of your claim

It is common for the other driver, or their insurer, to deny fault at first. That can feel disheartening, especially when you know what happened. Try not to be put off by it.

A denial simply changes what needs to happen next. Instead of fault being accepted, it now has to be shown using evidence. Many claims begin with a dispute and still go on to be resolved.

This is exactly the kind of situation where a regulated specialist solicitor can help. Part of their job is to test a denial and gather the evidence that supports your account.

How fault is established

Liability is worked out from evidence, not from who speaks loudest. Several types of evidence can all help build the picture.

Witnesses can matter a great deal. An independent person who saw the collision may confirm what happened. Their contact details, taken early, can be very valuable.

Dashcam and CCTV footage can be decisive. Your own camera, another road user's, or a nearby business or council camera may have captured the moment.

The police report, vehicle damage, and the position of the vehicles can all say something about how a collision occurred. In more complex cases, an expert in accident reconstruction may be asked to give an opinion on how it happened.

When insurers wrongly blame the rider

Motorcyclists are sometimes blamed unfairly. Insurers may raise points about filtering, speed, or road position and suggest the rider was at fault.

Filtering through slow or stationary traffic is a normal and lawful part of riding when done with care. The fact that you were filtering does not automatically make a collision your fault.

Assumptions about speed or where you were on the road are not the same as proof. A specialist can challenge these points and ask for the evidence behind them, rather than letting an assumption stand unchallenged.

Split liability and contributory negligence

Sometimes fault is not all on one side. Two terms come up here, and it helps to understand them in plain language.

Split liability means both sides are treated as sharing responsibility for the accident to some degree. The exact share depends entirely on the facts and evidence.

Contributory negligence means you are found to have contributed to your own injuries in some way, even if the accident was mainly caused by someone else. How this is handled depends on the individual case, and it does not necessarily prevent a claim.

What happens if liability stays disputed

If a denial stands, the claim usually follows a structured process. A letter of claim sets out what happened and why the other side is said to be responsible.

There is then a period of investigation, during which evidence is gathered and considered by both sides. Insurers often review their position once the evidence is in front of them.

Court proceedings are sometimes started if matters cannot be agreed, but going to court does not mean a case will end up in a trial. Most claims still settle without a final hearing. Whether court is appropriate depends on the individual case.

Why early evidence matters so much

Evidence is strongest when it is fresh. Footage gets overwritten, memories fade, and vehicle damage gets repaired. Acting early helps preserve what may later prove your account.

If you safely can, note the details of any witnesses, keep your own dashcam footage, and photograph the scene, the vehicles, and the damage. Keep a note of your injuries and how they affect you.

You do not have to work all of this out alone. A specialist solicitor can advise on what to preserve and can request footage or records before they are lost.

Try not to be discouraged

An initial denial is a common opening position, not a final verdict. It does not measure the strength of your account or the value of what happened to you.

What matters is the evidence and how it is presented. That is why gathering and preserving it early, and getting the right advice, can make a real difference.

Common questions

Questions riders ask

Answers to common queries regarding the claims process.

No. A denial does not end a claim. It means fault has to be proven using evidence rather than being accepted. Many claims start with a dispute and are still resolved once witnesses, footage, and other evidence are considered. A specialist solicitor can test the denial and gather what is needed, though no outcome can be guaranteed.

Not automatically. Filtering through slow or stationary traffic is lawful when done with reasonable care. The fact that you were filtering does not on its own make a collision your fault. A specialist can challenge assumptions about filtering, speed, or road position and ask for the evidence behind them. How it applies depends on your individual case.

Split liability means responsibility for the accident is treated as shared between both sides to some degree, rather than resting entirely with one person. The exact share depends on the facts and the evidence. It is decided case by case. This is general information only, and a regulated solicitor can explain how it might apply to your particular situation.

Often not. If liability stays disputed, court proceedings are sometimes started, but that does not mean a case ends in a trial. Most claims still settle without a final hearing once evidence is exchanged. Whether court is appropriate depends on the individual case, and a specialist solicitor can advise you as things progress.

If you can do so safely, keep witness contact details, your own dashcam footage, and photographs of the scene, vehicles, and damage. Note your injuries and how they affect daily life. Evidence is strongest when fresh, because footage is overwritten and memories fade. A specialist can also request footage or records before they are lost.
