Car accident lawyer St Georges Basin: 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.

• The lane each vehicle was in, and any lane change
• What the traffic lights or give-way signs showed
• Where each car came to rest, photographed before moving if safe
• Weather, light and the road surface at the time

Insurers look at more than who hit whom. They may ask whether you wore a seatbelt, how fast you were going and whether you were distracted. The finding is usually a percentage. A small one trims damages and later weekly payments. One greater than 61% has a much bigger effect, because it rules out damages altogether.

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.

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.

• 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

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 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.
