Impact of 40% Fault on Insurance Rates

If I’m determined to be 40% at fault for a car accident, how will that influence my future insurance premiums? I’ve looked online, but the answers I find are often too vague.

  1. The impact of being found 40% at fault in an auto accident on your future insurance rates can vary significantly based on several factors, including your insurance company’s policies, your overall driving history, the specifics of the accident, and state regulations.

    Generally speaking:

    1. Severity of the Accident: If the accident resulted in significant damage or injuries, your rates might increase more than if it were a minor incident.

    2. Insurance Provider: Different insurers will have varied algorithms for calculating rate increases. Some might be more lenient on partial fault, while others might impose heavier penalties.

    3. Previous Claims History: If you have a clean driving record prior to this accident, the increase might be less severe than if you’ve had multiple claims.

    4. State Laws: Some states follow a no-fault system, while others determine fault-based liability differently, which could affect how your rates are calculated after an accident.

    5. Percentage of Fault: Being found 40% at fault might lead to a moderate increase, but exact percentages can be hard to predict. It’s not uncommon for insurance premiums to rise by 20% to 40% after a partial fault accident, but this can vary.

    To get a more specific estimate, it might be best to contact your insurance agent for details on how this incident might impact your particular policy. They can provide insight tailored to your situation and help you understand any potential rate changes.

  2. If I was stopped and still listed as 40% at fault. How do I fight it? Obviously they just want to raise my rates.

  3. You're absolutely right to be skeptical. Insurance companies do often assign partial fault (like 40%) in shared-liability cases because it gives them legal and financial wiggle room – and yes, it can be a way to justify hiking your premium. But you can absolutely fight it, and here's a practical breakdown of how to do it:

    1. Understand Their Reasoning
    Ask your insurer:

    Why exactly were you assigned 40% fault?
    What evidence or legal principle are they using (e.g. comparative negligence laws)?
    Was there a police report, dash cam, or witness?

    Request everything in writing.

    2. Gather Your Evidence
    Build your case like a lawyer. You'll need:

    Police report (even if it doesn't assign blame – it matters)
    Dash cam footage (yours or theirs – you can request theirs)
    Photos from the scene (position, road conditions, damage)
    Witness statements (try to get these written or recorded)
    Relevant traffic laws (were you legally stationary? parked? pulled over?)

    If you were stationary and not violating any road rule, you should not be assigned fault at all.

    3. Write a Formal Dispute Letter
    Include:

    Policy number, incident date, and reference number
    A calm but firm explanation of why the 40% fault is incorrect
    All your evidence attached
    A request to escalate the dispute or for a review by a different adjuster

    4. Escalate to the Insurance Ombudsman or Regulator
    If they refuse to revise it, escalate outside the company:

    In the UK: Financial Ombudsman Service (https://www.financial-ombudsman.org.uk)
    In the US: Your State Department of Insurance
    In Australia: AFCA (Australian Financial Complaints Authority)

    These services are free, and just mentioning them can make insurers change tune.

    5. Tips to Strengthen Your Position

    Don't admit partial fault verbally during calls or emails.
    Emphasize your role as a stationary, non-contributing vehicle in the incident.
    If another driver hit you, and you were not moving, liability should be 100% theirs unless you were parked illegally or unsafely.

    Bottom Line
    They bet on people just accepting the partial fault to avoid hassle. But when you push back methodically – especially with documentation and legal knowledge – they often fold. You're not just defending your wallet; you're protecting your driving record too.
