Car accident lawyer Collaroy Beach: drivers, passengers and 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.

• What the traffic lights or give-way signs showed
• Where each car came to rest, photographed before moving if safe
• Exactly what the other driver said, written down that day
• Weather, light and the road surface at the time

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.

• Dashcam footage, saved as the original file
• The police event number and any police record
• Camera footage from nearby shops or homes
• Photos of signals, signs and lane markings

Contributory negligence means you are found to have contributed to the crash or to your own injuries. Common examples are not wearing a seatbelt, speeding, or travelling with a driver you knew had been drinking. It doesn't usually stop a claim. It can reduce weekly payments after 52 weeks and reduce damages, and above 61% you are treated as mostly at fault.

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.

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.

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.

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.

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.

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.
