Car accident lawyer, Oakdale: who was at fault?

The insurer that decides fault will not have been there. It relies on what people recorded at the time. So record what you can: the time, the weather, the road surface, the lane markings and the direction each vehicle was travelling. If a witness stopped, ask whether they'll give their name. A note written that evening is worth more than a memory months later.

• What the traffic lights or give-way signs showed
• Where each car came to rest, photographed before moving if safe
• Names and phone numbers of anyone who saw it
• Exactly what the other driver said, written down that day

Contributory negligence means you are found to have contributed to the crash or to your own injuries. Common examples are not wearing a seatbelt, speeding, or travelling with a driver you knew had been drinking. It doesn't usually stop a claim. It can reduce weekly payments after 52 weeks and reduce damages, and above 61% you are treated as mostly at fault.

Being a passenger doesn't make fault irrelevant. It shifts the question to the drivers. If the driver of your car and another driver both contributed, your claim may involve both vehicles' insurers. Your own conduct can still come up in limited ways, such as not wearing a seatbelt or travelling with a driver you knew was affected by alcohol.

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.

An independent witness, someone with no link to either driver, can carry real weight. Get their name and phone number at the scene if you can. If you can't, the police record may have their details. Photos of the final positions of the vehicles also matter, since damage patterns often show the angle and order of impact.

Some evidence only exists for a short time: skid marks, debris, temporary signs and camera footage. Other evidence can be gathered later, such as the police record and witness statements. If fault is disputed, a lawyer can ask for footage and records to be kept and, where the claim justifies it, obtain an expert opinion on how the crash happened.

• Dashcam footage, saved as the original file
• The police event number and any police record
• Photos of both vehicles' damage and final positions
• Your own written account from the first days

Chain collisions are where fault gets complicated. The driver who started it may carry most of the blame, but a driver behind who was following too closely can share it. Each vehicle has its own Green Slip insurer. Your task is to record every vehicle involved and the order of the impacts; the insurers' task is to sort out which of them responds.

The police event number is often the thread that ties a multi-vehicle crash together. It links the drivers, the vehicles and any statements taken at the scene. Keep it with your registration notes. CTP Assist, a free SIRA service on 1300 656 919, can help identify an insurer when you're unsure, though it won't decide fault for you.

Fault works more like a dial than a switch. A small share reduces some later entitlements. A share above 61% limits benefits to the first 52 weeks and rules out damages. No share at all keeps every option open. Knowing where the evidence puts you on that dial helps you decide whether a lawyer's view is worth having before the insurer settles its position.

A fault finding isn't final just because the insurer has made it. Most insurer decisions can go to internal review, generally within 28 days of receiving the decision, and then to the Personal Injury Commission. Before you accept a finding that you were mostly at fault, have someone look at whether the evidence supports it, because so much turns on that line.
