Top Mistakes to Avoid When Filing a Motor Vehicle Claim

08/04/2026

When you’re recovering from a car accident, the last thing you need is a compensation claim that falls apart because of an avoidable mistake. Yet we see it happen regularly – claims that could have secured fair compensation end up undervalued or rejected entirely because crucial steps were missed or mishandled.

The claims process isn’t designed to be simple. Insurers have entire teams whose job involves minimising payouts, and they’re adept at spotting weaknesses in your claim. One poorly worded statement, one missed medical appointment, or one gap in your documentation can become the reason your claim gets knocked back or significantly reduced.

Understanding what not to do is just as important as knowing the right steps to take. We’ve worked with hundreds of people who’ve been injured in motor vehicle accidents across Western Australia, and we’ve identified the patterns that consistently undermine claims. These aren’t small technical issues – they’re substantial errors that can cost you thousands of dollars in compensation you’re genuinely entitled to.

Admitting Fault at the Scene

The moments after a collision are chaotic. You’re shaken, possibly injured, and trying to process what just happened. It’s natural to want to apologise or say something to defuse the tension, but even a simple “I’m sorry” can be interpreted as an admission of liability.

Insurance companies will scrutinise every statement you make at the scene. What you intend as basic politeness or shock-induced rambling can be twisted into evidence that you were responsible for the accident. We’ve seen claims where a client’s throwaway comment – “I didn’t see you there” – became the insurer’s primary argument for denying compensation.

Keep your communication factual and minimal. Exchange details with the other driver, check if anyone needs immediate medical attention, and contact the police if required. Don’t discuss how the accident happened, don’t speculate about who was at fault, and don’t agree to any version of events on the spot.

If the other driver tries to get you to admit responsibility or suggests you were distracted or speeding, simply decline to discuss it. Your only obligation is to exchange insurance details and ensure everyone’s safety. Everything else can wait until you’ve had time to process what happened and seek proper advice.

Delaying Medical Treatment

Some injuries don’t announce themselves immediately. Adrenaline masks pain, and soft tissue injuries often take hours or days to manifest fully. By the time you realise you’re hurt, you might think it’s too late to link your injuries to the accident – but the real problem is that insurers will certainly think so.

Every day you wait to see a doctor is another day the insurer can argue your injuries weren’t caused by the collision. If you wait a week before seeking treatment, they’ll suggest you were injured doing something else in the interim. If you wait a month, they’ll claim the accident couldn’t have been serious enough to warrant compensation.

See a GP within 24-48 hours of the accident, even if you feel relatively fine. Explain exactly what happened and describe every ache, pain, or discomfort you’re experiencing, no matter how minor it seems. Your doctor needs to create a medical record that connects your injuries directly to the collision.

This initial medical record becomes the foundation of your claim. It establishes causation – the critical link between the accident and your injuries. Without it, you’re asking the insurer to take your word that your back pain started the day of the crash, not three weeks later when you lifted something heavy.

Failing to Document the Scene

Your memory of the accident will fade. Details that seem crystal clear in the immediate aftermath become fuzzy within days. Meanwhile, the other driver’s version of events might be completely different, and without evidence, it becomes your word against theirs.

Take photos of everything whilst you’re still at the scene. Capture damage to all vehicles from multiple angles, skid marks on the road, traffic signs, road conditions, and the overall layout of the intersection or road. If there’s debris, photograph it. If weather conditions contributed, document that too.

Get contact details from any witnesses, even if they only saw part of what happened. Independent witnesses can be invaluable when liability is disputed. Don’t rely on the police to collect this information – they might not attend minor accidents, and even when they do, their report might not include everyone who saw what happened.

Note the time, date, weather conditions, and lighting. If the other driver says anything about what happened or why, write it down as soon as possible. If there are security cameras nearby – at shops, petrol stations, or traffic lights – note their locations. This footage often gets deleted after 30 days, so you’ll need to act quickly to request it.

Accepting the First Settlement Offer

Insurers know that injured people need money quickly. Medical bills pile up, you might be off work, and the financial pressure mounts. They’re counting on you being desperate enough to accept whatever they offer first, which is almost always substantially less than what your claim is worth.

The initial offer typically covers only the most obvious, immediate costs. It won’t account for ongoing treatment you’ll need, future wage loss if your injuries prevent you from working at full capacity, or the long-term impact on your quality of life. Once you accept and sign a release, you can’t come back later when you realise your injuries are worse than you thought.

We regularly see first offers that are 30-50% below what the claim eventually settles for. Insurers build in room to negotiate because they expect you to counter-offer. If you accept immediately, you’re leaving money on the table that you’re legally entitled to claim.

Before accepting any offer, have your claim properly assessed. Understand the full extent of your injuries, get a prognosis from your doctors about long-term effects, and calculate all your losses – not just the bills you’ve received so far. You need to know what fair compensation looks like before you can evaluate whether an offer is reasonable.

Giving Recorded Statements Without Preparation

The insurer will ask you to provide a recorded statement about the accident. They’ll frame it as routine paperwork, just getting your version of events for their files. What they won’t tell you is that this recording will be analysed for any inconsistency, any vague statement, or any comment that could undermine your claim.

Insurance adjusters are trained in interview techniques designed to elicit statements that benefit the insurer. They’ll ask leading questions, request unnecessary details, and try to get you to speculate about things you don’t actually know. If you contradict yourself – even on minor points – they’ll use it to argue that your entire account is unreliable.

You’re not legally required to give a recorded statement immediately, and you shouldn’t do it without understanding what’s at stake. If you’ve already given one and said something problematic, that doesn’t necessarily destroy your claim, but it makes everything harder.

Before speaking to the insurer, organise your thoughts. Review any notes you made after the accident, look at your photos, and be clear about what you actually remember versus what you’re guessing. It’s perfectly acceptable to say “I don’t recall” or “I’m not sure about that detail” rather than speculating.

Posting on Social Media

Your social media accounts are not private, regardless of your settings. Insurers routinely monitor claimants’ social media profiles looking for evidence that contradicts their claimed injuries. That photo of you at your niece’s birthday party gets presented as proof you’re not really in pain. The post about your weekend plans suggests you’re not as limited as you claim.

Even innocent posts can be misconstrued. You mention going for a walk because your physio recommended gentle exercise – the insurer argues you’re clearly mobile and not seriously injured. You smile in a family photo – they suggest you’re not suffering psychological trauma. You check in at a restaurant – they claim you’re well enough to socialise normally.

The safest approach whilst your claim is active is to avoid posting anything about your activities, your injuries, or your daily life. Don’t post photos of yourself, don’t check in at locations, and don’t comment on posts that might reveal what you’re doing. Assume everything you post will be screenshot and presented to undermine your claim.

Tell your friends and family not to tag you in posts or photos. Even if you’re not posting yourself, photos others share can still be used against you. One client’s claim was challenged because her sister posted photos from a family gathering – the insurer argued that if she was well enough to attend, her injuries must not be severe.

Settling Before Understanding Full Injury Impact

Some injuries reveal their true extent slowly. What seems like a moderate back strain might develop into chronic pain requiring ongoing treatment. A concussion might lead to persistent cognitive difficulties that affect your ability to work. Psychological trauma might not fully manifest until months after the accident.

If you settle your claim before your injuries have stabilised, you’re making a binding decision based on incomplete information. Once you accept a settlement and sign a release, you can’t reopen the claim when you discover your injuries are worse than initially thought or that you need surgery you didn’t anticipate.

Your doctors need time to assess your prognosis properly. Will you make a full recovery, or will you have permanent limitations? Will you need future medical treatment? Can you return to your previous job, or will your injuries prevent you from doing certain types of work? These questions can’t be answered in the first few weeks after an accident.

We’ve worked with clients who settled quickly for what seemed like reasonable compensation, only to discover months later that they needed surgery costing tens of thousands of dollars. Because they’d already settled, they had no recourse. The insurer had closed the file, and they were left bearing costs that should have been covered.

Inconsistent Medical Treatment

Gaps in your medical treatment create doubt about the severity of your injuries. If you claim to be in constant pain but you missed three physio appointments and haven’t seen your GP in two months, the insurer will argue you’re not really that badly hurt.

Consistent treatment demonstrates that your injuries are genuine and require ongoing care. It also creates a medical record that tracks your recovery progress and documents setbacks or complications. This record becomes crucial evidence when quantifying your claim.

If you can’t attend an appointment, reschedule it immediately. If financial constraints are preventing you from getting treatment, discuss this with your lawyer – there may be options for funding treatment through your claim. Don’t simply skip appointments without explanation.

Follow your doctors’ recommendations precisely. If they refer you to a specialist, book that appointment. If they prescribe medication, take it as directed. If they recommend physio twice a week, attend twice a week. Insurers will comb through your medical records looking for evidence that you didn’t follow medical advice, which they’ll use to argue that you contributed to your own poor recovery.

Not Keeping Detailed Records

Your claim depends on evidence. Without documentation, you’re asking the insurer to simply trust that you’ve incurred the losses you’re claiming. They won’t. Every dollar you claim needs to be supported by a receipt, invoice, or other proof.

Keep copies of every medical bill, pharmacy receipt, and invoice for any accident-related expense. Track your mileage to medical appointments. If you pay for parking at the hospital, keep the ticket. If you need to purchase medical equipment or modify your home because of your injuries, document it.

Create a pain diary that tracks your symptoms, limitations, and how your injuries affect your daily life. Note when pain prevents you from sleeping, when you can’t play with your children, when you need help with basic tasks. This contemporaneous record is far more credible than trying to recall these details months later when you’re preparing your claim.

If you miss work, get documentation from your employer confirming the dates and the income you’ve lost. If you use sick leave or annual leave to cover your absence, that’s still a loss – you’ve depleted leave you would otherwise have available. If your injuries prevent you from doing overtime you’d normally work, document your usual overtime patterns.

Handling the Claim Without Legal Advice

Insurance companies have lawyers. They have claims specialists who handle hundreds of cases a year. They have actuaries who calculate the minimum they can offer whilst still getting you to accept. You’re facing this alone, probably for the first time in your life, whilst dealing with injuries and financial stress.

The playing field isn’t level. You don’t know what your claim is worth. You don’t know what evidence is crucial. You don’t know the tactics insurers use to minimise payouts. You don’t know when an offer is reasonable or insulting. You’re negotiating blind whilst the insurer holds all the cards.

Accident Claims Lawyers offers a free initial assessment where we review your case, explain your rights, and help you understand what fair compensation looks like. There’s no obligation, and it costs nothing to find out whether you’re being treated fairly.

We work on a no-win, no-fee basis for motor vehicle accident claims, which means you don’t pay legal fees unless we successfully recover compensation for you. This removes the financial barrier that prevents many injured people from getting proper legal representation.

The mistakes outlined here aren’t theoretical. We see them in almost every case where someone has tried to handle their claim alone before coming to us. By that point, we’re often in damage control mode, trying to salvage a claim that’s been compromised by avoidable errors.

Understanding Your Rights Under WA Law

Western Australia’s motor vehicle injury scheme operates differently from other states. If you’re injured in a motor vehicle accident in WA, you may be entitled to claim through the Insurance Commission of Western Australia (ICWA) for catastrophic injuries, or through the at-fault driver’s insurer for other injuries.

The scheme covers medical expenses, wage loss, domestic assistance, and pain and suffering, but there are strict time limits and procedural requirements. You generally have three years from the date of the accident to commence legal proceedings, but there are benefits to starting your claim much earlier.

Your entitlements depend on the severity of your injuries and how they impact your life. Minor injuries might warrant a few thousand dollars. Serious injuries that prevent you from working or require ongoing treatment can justify claims worth hundreds of thousands of dollars. Catastrophic injuries – those that result in permanent severe impairment – can lead to multi-million dollar settlements.

The insurer won’t volunteer information about what you’re entitled to claim. They’ll ask what you want to claim and then tell you whether they’ll pay it. Without understanding the full scope of your entitlements, you can’t possibly know whether you’re being offered fair compensation.

When to Seek Professional Help

Not every minor accident requires a lawyer. If you’ve got a small amount of vehicle damage, no injuries, and the other driver’s insurer is being reasonable, you can probably handle it yourself. But if you’ve been injured – even if those injuries seem relatively minor – the stakes are high enough that professional advice is worthwhile.

Seek legal advice immediately if you’ve suffered serious injuries, if liability is being disputed, if the insurer is delaying or denying your claim, or if you’re being pressured to settle quickly. These are red flags that indicate you need professional representation.

You should also get advice if you’re unsure about the value of your claim. Many people accept settlements that are far below what they’re entitled to simply because they don’t know any better. A proper assessment costs you nothing but could reveal that your claim is worth substantially more than you thought.

If you’re feeling overwhelmed by the process, that’s normal – and it’s a sign you’d benefit from professional help. Claims involve extensive paperwork, medical assessments, negotiations with adjusters who do this for a living, and legal procedures you’ve never encountered before. You don’t have to navigate this alone whilst you’re trying to recover from your injuries.

Contact us today for a free, no-obligation assessment of your motor vehicle accident claim. We’ll review what’s happened, identify any mistakes that need to be addressed, and explain your options clearly. You’ll leave the conversation understanding your rights and what you should do next, whether that’s proceeding with our assistance or handling it yourself with better information.

The difference between a poorly handled claim and a properly managed one can be tens of thousands of dollars – money you’re legally entitled to receive. Don’t let avoidable mistakes cost you the compensation you need to recover from your injuries and move forward with your life.
