Lane Etiquette

Do you know how to safely merge, change lanes and enter a freeway – or are you that driver that causes gritting of teeth and frustration for other drivers as they ever so slowly sail onto the freeway to the sound of screeching brakes behind them?

Situations such as this can be the cause of very serious accidents – if the driver behind is not alert and able to react in time.

Some drivers are just, to put it plainly, inept – while others may interpret the rules of the road differently and unintentionally.

In Australia, we have two different types of merge. Firstly, the dotted line merge, which is when a lane comes to an end, and a dotted line separates the end of the lane and the entry into the next lane. This is like the highway onramps and offramps. In a dotted line merge, the car in the lane with the dotted line has to give way to the cars in the other lane. This means that even if you are a nose ahead of the car in the adjacent lane – you need to slow down and give way to this car. From an etiquette perspective – if you are the driver in the lane into which the dotted lane car is merging – it is really polite to speed up or slow down to make room for this driver. If you are merging, match the speed of the cars in the lane that you are merging into – don’t try to enter a freeway doing 40 km/h – you will be an accident waiting to happen. Try not to stop in the merging lane especially when you enter a freeway – you need to achieve the speed of the cars travelling on the freeway safely, within the distance available to you, without losing momentum while also timing the availability of a gap in the cars that you will be able to get into.

The other type of merge is where two lanes become one, and the dividing line stops. In this case, whoever in in front has right of way. Good etiquette in this situation is to take turns to merge – like a zipper.

As far as changing lanes is concerned – keep left and overtake right on multilane roads. On a highway, make sure to use the fast lane for overtaking and move back into the slow lane when safe to do so.

What To Do If Someone Hits Your Parked Car

Coming back to find your parked car damaged is never fun, but knowing how to respond correctly can save you time, money and stress.

Firstly, understand that getting upset is natural, but taking a deep breath will help you make better decisions. Examine your car thoroughly and document any visible damage, taking multiple photos from different angles, including close-ups of dents, scratches or broken parts, and capturing the surrounding area, such as road signs and markings, for context.

Next, see if you can locate the driver responsible. Sometimes, people leave a note with their contact information and insurance details. If there’s no note, look for witnesses nearby who may have seen what happened. You can also check for CCTV from nearby businesses, homes or on the street, as some areas have coverage. If you’re unsure, consider contacting the local council to find out whether cameras are in place that might have captured the accident.

If the driver didn’t leave a note, or if they did but are unresponsive or the information they provided seems incorrect, contact the police to report the accident and provide all the information you have, including photos, footage and witness statements. Be sure to request a copy of the police report, as it can be useful when dealing with insurance.

If you’re still having a hard time getting a hold of the at-fault driver and therefore cannot claim directly through their car insurer, it’s time to lodge a claim with your own insurance provider, if you have one. Provide them with as much information as possible, including the police report. From there, your insurer can determine whether your coverage, along with the information you have, will cover the damage to your car.

If your car insurer happens to find information about the at-fault driver and is able to have them lodge a claim so the costs of the damage are recoverable, you can contact Carbiz for a replacement car while your car is being repaired or until it’s been deemed a total loss. This ensures you’re not left without a car during this time, giving you peace of mind and the ability to keep your life moving.

What It Means When Your Car Is Declared A Write-Off After An Accident

Updated 6 October 2026.

When an insurer declares a car a write-off, it has assessed the vehicle as a total loss under the policy. The damage may make repairs unsafe, or the cost of repairing the car may make a repair uneconomical. A write-off does not always mean the car is visibly destroyed.

How is a write-off decision made?

The assessment can take account of the vehicle's value, repair costs, salvage value and the policy terms. There is no single repair-cost percentage that determines every write-off across Australia. Ask the insurer for its assessment and the basis for its decision.

A total-loss insurance decision and a vehicle's written-off registration category are related but different matters. Whether a car can return to the road depends on the damage classification and the rules of the relevant state or territory.

Statutory and repairable write-offs

Statutory write-off: the vehicle meets specified damage criteria and cannot be re-registered for road use.
Repairable write-off: repairs may be technically possible, but the vehicle has been assessed as uneconomical to repair. This label does not itself authorise repairs or guarantee re-registration.

Requirements vary across Australia. In NSW, an eligible written-off light vehicle needs an Authorisation to Repair from Transport for NSW before work begins. Only limited applications are considered, and vehicles with statutory write-off damage are excluded. Approval, compliant repairs and the required inspections are separate steps.

What happens to your insurance payout?

The settlement depends on your cover and circumstances. It may be based on an agreed value, a market value or a replacement-vehicle benefit if your policy provides one. An excess, outstanding premium or finance arrangements may affect the amount you receive. Ask for a written breakdown before accepting the settlement.

Keep the assessment, photographs, policy documents and correspondence together. If you disagree with the valuation, provide relevant evidence and use the insurer's complaints process. See AAMI's explanation of total-loss claims for an insurer's example; your own policy determines your cover.

Getting around after a not-at-fault accident

If you need a replacement vehicle, tell Carbiz that your car has been declared a write-off. Eligibility, vehicle availability, the hire period and the terms of the agreement need to be confirmed for your circumstances. A write-off does not automatically entitle everyone to unlimited hire.

Contact Carbiz to discuss your accident replacement vehicle options. For a practical checklist, read what to do after receiving a write-off decision.
