How Insurance Claims Work After an Accident in Missouri

Missouri uses an at-fault (tort) insurance system. The driver who caused the accident is financially responsible for the other party's damages — medical bills, lost wages, vehicle repair, and pain and suffering. Missouri does not use a no-fault system, so there is no personal injury protection (PIP) requirement.

As the injured party in Missouri, you have three paths to compensation. You can file a third-party claim directly against the at-fault driver's liability insurance. You can file a first-party claim with your own insurer under your collision, medical payments, or uninsured motorist coverage. Or you can file a personal injury lawsuit in court. Most claims start with the insurance process and move to litigation only if settlement negotiations stall.

Missouri's pure comparative fault rule (RSMo 537.765) applies to insurance claims. If you are partially at fault, your compensation is reduced by your fault percentage — but unlike most neighboring states, there is no threshold that bars recovery. Even at 99% fault, you recover 1% of your damages. Insurance adjusters know this and will still work to inflate your fault percentage to reduce what they owe.

Missouri law requires all drivers to carry minimum liability insurance under the Motor Vehicle Financial Responsibility Law (RSMo 303.190). The required minimums are 25/50/25: $25,000 bodily injury per person, $50,000 bodily injury per accident, and $25,000 property damage per accident. Driving without insurance in Missouri can result in license suspension, vehicle impoundment, and fines.

These minimums are often inadequate for serious injuries. A single emergency room visit, surgery, and a week of hospitalization can exceed $25,000 before rehabilitation even begins. If the at-fault driver carries only minimums and your medical bills are $90,000, you face a $65,000 gap that their insurance will not cover. This is why your own underinsured motorist coverage matters.

Missouri also requires that you report any accident involving injury, death, or property damage exceeding $500 to law enforcement. If either party is uninsured, you must also file a Motor Vehicle Accident Report with the Missouri Department of Revenue.

Uninsured motorist (UM) coverage is mandatory in Missouri under RSMo 379.203 at minimums of $25,000 per person and $50,000 per accident for bodily injury. Missouri law specifically prohibits drivers from waiving UM coverage — this is unusual. Most states allow a written rejection. Missouri does not.

UM coverage protects you when the at-fault driver has no insurance, is a hit-and-run driver, or carries a policy from an insolvent insurer. Missouri UM coverage applies to bodily injury only — it does not cover property damage. The coverage extends to the named insured, family members, passengers in the insured vehicle, and pedestrians or cyclists struck by an uninsured driver.

Underinsured motorist (UIM) coverage is available but not required in Missouri. UIM coverage fills the gap when the at-fault driver has insurance but their limits are too low to cover your actual damages. Given Missouri's low minimum requirements, carrying UIM coverage is one of the most important financial decisions you can make before an accident happens.

Step 1: At the scene, call 911 if there are injuries. Exchange insurance and contact information with all drivers, photograph damage and the scene from multiple angles, and get contact information for witnesses. Do not admit fault or apologize — these statements can be used against you. Step 2: Report the accident to police. Missouri law requires reporting any accident involving injury, death, or property damage over $500. Request a copy of the police report — you will need it for your claim.

Step 3: Notify your own insurance company promptly. Most Missouri policies require notification within a reasonable time after the accident, even if you were not at fault. Provide basic facts: date, time, location, vehicles involved, and the police report number. Do not speculate about fault or minimize your injuries. Step 4: Seek medical treatment immediately. Delayed treatment hurts both your health and your claim. Adjusters will argue that gaps in treatment prove your injuries are not serious.

Step 5: File your claim — either a first-party claim with your own insurer or a third-party claim against the at-fault driver's insurer. You will need your insurance details, the other driver's information, the police report, and documentation of your damages. Step 6: The insurer must acknowledge receipt of your claim within 10 business days and approve or deny it within 15 business days. Step 7: The adjuster investigates, calculates an offer, and presents a settlement. You can accept, negotiate, or reject and file a lawsuit within the 5-year statute of limitations.

The insurance adjuster works for the insurance company, not for you. Their performance is measured by how much they save the company. They are trained professionals who handle hundreds of claims — and they know how to get you to say things that reduce your payout.

Share: your name and contact information, the date and location of the accident, that you were involved in the accident, and that you are receiving medical treatment. Direct the adjuster to your attorney if you have one. Never say: 'I'm fine' or 'I feel okay' (soft tissue injuries, concussions, and herniated discs often worsen over days or weeks), 'I'm sorry' or anything that could be interpreted as admitting fault, speculation about how the accident happened, or details about pre-existing conditions without legal guidance.

Do not give a recorded statement to the other driver's insurance company. Missouri law does not require you to provide one. A recorded statement creates a permanent transcript the adjuster can comb through for inconsistencies. If the adjuster pressures you, say: 'I decline to give a recorded statement at this time.' If you have already said something you regret, stop all communication with the adjuster and consult an attorney before any further contact.

Reject a settlement offer if: you have not reached maximum medical improvement (MMI), the offer does not cover all medical expenses including anticipated future treatment, the offer ignores lost wages and reduced earning capacity, or the offer does not include fair compensation for pain and suffering. First offers from insurance companies are almost always below what the claim is actually worth.

An offer may be reasonable if: you have reached MMI and know your full medical costs, the offer covers all economic and non-economic damages, the at-fault driver's policy limits have been reached and you have no UIM coverage, or further litigation costs would exceed the likely additional recovery.

Once you accept a settlement and sign a release, the claim is permanently closed. You cannot reopen it if your condition worsens, you need additional surgery, or you develop complications. Missouri's 5-year statute of limitations gives you time to fully understand your injuries before settling. Do not let the insurance company's urgency force you into a premature decision — their rush to close your claim usually means it is worth more than they are offering.

Missouri law provides protections when an insurance company unreasonably refuses to pay a valid claim. Under RSMo 375.420, if an insurer's refusal to pay is found to be vexatious and without reasonable cause, the court can award penalty damages — up to 20% of the first $1,500 of the loss plus 10% of the amount exceeding $1,500 — plus reasonable attorney fees.

RSMo 375.296 requires insurers to pay claims within 30 days of a proper demand. Failure to do so can result in damages for vexatious refusal plus attorney fees. To prove vexatious refusal, you must show that a valid policy existed, the insurer refused to pay, and the refusal was without reasonable cause or excuse.

Missouri also has specific requirements for time-limited settlement demands. Under RSMo 537.058, for a settlement demand to be admissible as evidence of insurer bad faith, it must be sent in writing by certified mail to the liability insurer and must specifically reference the statute. If an insurer ignores a properly structured demand and the case goes to verdict above policy limits, this creates evidence for a bad faith claim. These protections give injured Missourians real leverage against insurers who stall or lowball claims.

Missouri's statute of limitations for personal injury claims is 5 years from the date of injury under RSMo 516.120 — one of the longest in the country. For wrongful death, the deadline is 3 years from the date of death under RSMo 537.100. Property damage claims also have a 5-year deadline.

The discovery rule may extend these deadlines in certain cases. The clock starts when the injury 'became capable of ascertainment,' not necessarily the date of the accident. For minors and those who are mentally incapacitated, the full limitation period does not begin running until the disability ends under RSMo 516.170.

While 5 years is generous, do not wait. Evidence deteriorates, witnesses forget, and surveillance footage gets overwritten. The insurance company gains leverage as time passes. Starting your claim early — ideally within weeks of the accident — preserves evidence and puts you in the strongest negotiating position.
