Car accident lawyer Villawood: drivers, passengers and fault

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
• Exactly what the other driver said, written down that day
• Whether you and your passengers wore seatbelts
• Weather, light and the road surface at the time

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.

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.

Many passengers hesitate to claim because the driver was someone close to them. It helps to know the claim is made against the CTP insurer, which exists for exactly this situation. The driver may be asked for their account, and any fault finding affects their own claim, not your right to make yours. Talk it through if you're worried about how it will land.

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.

• Photos of both vehicles' damage and final positions
• Independent witnesses' names and numbers
• Your own written account from the first days
• Any messages the other driver sent after the crash

Think of the claim in two parts. Statutory benefits come first and, for most people, don't depend on who caused the crash. Common law damages come later and depend heavily on it: another driver must have been at fault, you must not have been mostly at fault, and the injury must be more than a threshold injury. That is why fault is worth attention early.

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.

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.

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.
