Partly at fault? Car crash lawyer help for Bardwell Park

You don't need to decide who caused the crash at the scene, and it's wiser not to argue about it there. Swap details, stay calm and avoid guessing about speeds or blame. What helps most later is a clear record: photos of the vehicles' positions, the road layout and any witness who saw it happen, with their name and number.

• What the traffic lights or give-way signs showed
• Names and phone numbers of anyone who saw it
• Exactly what the other driver said, written down that day
• Weather, light and the road surface at the time

Passengers usually have the simplest fault position of anyone in a crash. You weren't in control, so the question is only which driver caused it, and that decides which insurer deals with you. Where both drivers share the blame, you may still be blameless yourself. That matters later, because damages depend partly on your own share of fault.

Children in the car are in a special position. Whoever caused the crash, a child aged 16 or under at the time can keep receiving treatment and care for as long as they need it. Usually a parent or guardian lodges the claim for them. Fault can still matter for other entitlements, so keep the police record with the child's medical records.

Most people hurt in a car crash can claim statutory benefits regardless of fault, covering weekly payments and reasonable and necessary treatment. Fault matters most for the lump sum. Common law damages are only possible if another driver was at fault, you were not mostly at fault, and your injury is more than a threshold injury. So a fault finding against you can close off damages even while benefits are paid.

A seatbelt argument is the classic example. If the insurer says your injuries were worse because you weren't belted in, it may reduce what you receive. The percentage isn't set by a formula. It's argued on the evidence, including medical opinion about how each injury happened, which makes it worth checking rather than simply accepting.

Dashcam footage is often the clearest evidence of fault, but many cameras record over themselves within hours or days. Save the original file as soon as you can, and don't trim or edit it. If another driver or a nearby business may have footage, ask early and in writing, because it may not be kept for long.

The police event number links your claim to the official record of the crash. The insurer can use it to check who was involved and what was reported. It's worth getting even if the crash seemed minor and police didn't attend, because a record made close to the time is harder to dispute than one pieced together later.

• Dashcam footage, saved as the original file
• The police event number and any police record
• Photos of both vehicles' damage and final positions
• Any messages the other driver sent after the crash

When three or more vehicles are involved, fault can be divided between several drivers. That affects which insurer deals with you and may affect how any damages are shared between insurers later. It generally doesn't stop you receiving statutory benefits while that is argued. If the insurers are still disputing it weeks after you lodge, advice is worth getting.

If you were hit from behind and pushed into the car in front, you may have been blameless in both impacts. Make that clear in your account: which impact came first, and whether you had stopped before being hit. Insurers sometimes treat a chain crash as one event, and the sequence is what shows your own share was nil.

If the other driver says you caused the crash, or the insurer won't accept that the other driver did, the evidence decides it. This is the point where an independent lawyer is often worth talking to. They can test the insurer's reasons, gather what's missing and advise whether to ask for a review. Insurers make decisions under the scheme rules, and those decisions can be challenged.
