Car accident lawyer, Mount Vernon: 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.

• 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
• Exactly what the other driver said, written down that day

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.

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
• Your own written account from the first days
• Photos of signals, signs and lane markings

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.

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.

A passenger isn't driving, so a passenger is rarely found at fault for the crash itself. The claim goes to the CTP insurer of whichever vehicle was at fault. If your own driver caused it, that's the Green Slip of the car you were in, even when the driver is a friend or family member. The insurer responds to the claim, not the driver personally.

Passengers in a crash between two cars sometimes find that each driver blames the other and neither insurer will accept the claim at first. You don't have to take sides. Give an honest account of what you saw, lodge on time, and let the fault question be worked out between the insurers. If it stalls, that's when advice helps most.

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.
