Car crash lawyer help with fault, for people in St Helens Park

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.

• 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
• Whether you and your passengers wore seatbelts

Fault is decided on evidence, not on who sounds more certain. The usual pieces are the police event number and any police record, photos of where the cars stopped, the damage to each vehicle, dashcam footage and independent witnesses. No single piece is always decisive. Together they usually show what happened, even when the drivers tell different stories.

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

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.

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.

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.

Passengers and drivers caught in the middle of a chain crash often feel stuck between insurers. Your claim generally shouldn't stall while the insurers sort out their shares. Keep a note of every call, who you spoke to and what they said. If no insurer will take responsibility, that is a good moment to ask for advice.

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.

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.

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.
