Blamed for a crash near Illawong? Car accident lawyer help

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.

• The lane each vehicle was in, and any lane change
• Where each car came to rest, photographed before moving if safe
• Skid marks, debris and the damage to each vehicle
• Weather, light and the road surface at the time

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.

In a two-car crash, the injury claim usually goes to the CTP insurer of the car at fault, which is your own vehicle's insurer if you caused it. When fault is shared or unclear, the insurers may not agree at first. That shouldn't hold up your claim. Lodge with the insurer that fits the evidence you have, and let the fault question be worked out as the claim proceeds.

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.

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.

• The police event number and any police record
• Independent witnesses' names and numbers
• Photos of signals, signs and lane markings
• Any messages the other driver sent after the crash

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.

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.

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.
