Car accident lawyer, Bungonia: who was at fault?

Fault arguments are built from small details. Before the cars are moved, if it is safe, photograph where each one stopped and the damage to each. Look for skid marks, debris and the traffic signals. Then write a short account in your own words: where you were going, what you saw, and when you first noticed the other vehicle. Keep it factual and keep it.

• The lane each vehicle was in, and any lane change
• Skid marks, debris and the damage to each vehicle
• Names and phone numbers of anyone who saw it
• Exactly what the other driver said, written down that day

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.

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.

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.

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.

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
• Independent witnesses' names and numbers
• Your own written account from the first days
• Photos of signals, signs and lane markings

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.
