Missouri Car Accident Laws: Fault, Insurance, and Your Claim

Missouri is an at-fault (tort) state that follows pure comparative negligence, so the at-fault driver's liability insurer pays for the other party's injuries and damages, and your recovery is reduced by your share of fault but never barred entirely, even if you were mostly at fault.

Is Missouri a no-fault or at-fault state?

Missouri is a traditional at-fault (tort) state. The state is not among the 12 no-fault or PIP-first jurisdictions, and Missouri does not have a choice no-fault or add-on system. When a crash occurs, the driver who caused it is responsible for the resulting injuries and property damage, and the at-fault driver's liability insurer covers the other party's losses. There is no preliminary no-fault threshold to clear before you can pursue a claim for pain and suffering.

Because Missouri operates as a pure tort state, an injured driver can go directly against the at-fault driver's insurer for all categories of damages, including medical expenses, lost wages, property damage, pain and suffering, and emotional distress. The Missouri Department of Revenue confirms that the state requires mandatory liability insurance rather than any form of personal injury protection. If the at-fault driver is uninsured or underinsured, you turn to the mandatory UM coverage on your own policy. There is no PIP benefit sitting between you and a full tort claim.

How fault is shared: Missouri's negligence rule

Missouri follows the rule of pure comparative negligence, which means that fault can be divided between multiple parties in any proportion and each party's damages are reduced only by that party's own share of fault. Your percentage of fault never bars your recovery entirely, no matter how high it goes. If a jury finds you were 80% responsible for a crash and the other driver was 20% responsible, you can still recover 20% of your total damages from the other driver.

This is a more plaintiff-friendly standard than the modified-comparative-negligence rules used in most states (which bar recovery once you pass 50% or 51% at fault). In Missouri, even a driver who was the primary cause of a crash retains some recovery rights. In practice, pure comparative fault places a premium on accurately establishing each party's contributions to the accident. Insurers and defense attorneys regularly try to inflate the plaintiff's fault percentage to shrink any payout. Thorough documentation, credible witnesses, and independent accident reconstruction, when available, make a significant difference in what a jury or adjuster accepts as each side's share of responsibility.

Minimum car insurance in Missouri

Missouri law (RSMo 303.190, cross-referenced in the financial responsibility chapter at RSMo 303.030) requires every registered motor vehicle to carry at least 25/50/25 in liability coverage: $25,000 for bodily injury per person, $50,000 for bodily injury per accident, and $25,000 for property damage per accident. These minimums establish the floor of what the at-fault driver's insurer must pay toward injured parties in a crash the policyholder caused.

Uninsured motorist bodily-injury coverage is also mandatory in Missouri under RSMo 379.203. Every auto policy must include UM coverage of at least $25,000 per person and $50,000 per accident. This protection pays you if you are injured by a driver who carries no insurance at all. Underinsured motorist (UIM) protection is embedded in the same statutory provision, although standalone UIM is not separately mandated at a specific limit. A policyholder may reject in writing only coverage above the statutory 25/50 minimum; the minimum UM coverage itself cannot be waived.

Missouri does not require personal injury protection (PIP). MedPay, which covers your own medical expenses up to a policy limit regardless of fault, is an optional add-on available from most insurers. Carrying MedPay can be a practical safeguard, because it covers treatment costs immediately while an at-fault claim works through the insurer's process.

How long you have to file: the statute of limitations

Missouri gives you five years to file a personal-injury lawsuit arising from a car accident. The deadline comes from RSMo 516.120(4), which covers any action for injury to the person or rights of another not arising on contract. Property-damage claims fall under the same five-year period. The five-year window is notably longer than the two- or three-year periods most other states impose, and multiple legislative efforts to shorten it to two or three years have failed, so the five-year rule remains current law.

Wrongful-death claims are governed by a separate and shorter deadline. Under RSMo 537.100, a wrongful-death action must be filed within three years of the death. If your accident involved a government vehicle or a government employee acting in an official capacity, special notice-of-claim requirements and shorter windows under Missouri's sovereign immunity statutes may apply before you can even file suit, so consult an attorney promptly if a government entity is involved. For a broader comparison of filing deadlines, see the Missouri statute of limitations page.

What a Missouri car accident claim is worth

Missouri car accident claims include two main categories of damages. Economic damages cover your measurable financial losses: past and future medical expenses, lost wages and earning capacity, vehicle repair or replacement, and other out-of-pocket costs traceable to the crash. Because Missouri is an at-fault state with no PIP mandate, none of those economic losses are absorbed by your own insurer first; they are all pursued directly against the at-fault driver's policy (or your UM/UIM coverage if the other driver lacks adequate insurance).

Non-economic damages cover pain and suffering, emotional distress, and loss of enjoyment of life. There is no pre-suit threshold to meet in order to claim these damages in Missouri; you can pursue them from the start of any tort claim. Your total recovery is shaped by the at-fault driver's 25/50/25 liability limits (unless they carry more), your own UM/UIM coverage, and the pure-comparative-fault reduction for any share of fault attributed to you. Serious injury cases with clear liability tend to produce higher settlements because both the availability and the amount of non-economic damages are harder to dispute.

What to do after a car accident in Missouri

Taking the right steps immediately after a crash protects both your health and your legal rights.

Stay safe and call for help. Move vehicles out of traffic if it is safe to do so. Call 911 if anyone is injured. Missouri law requires drivers involved in an accident resulting in injury, death, or property damage above the threshold to report the crash to law enforcement.

Document the scene. Photograph the vehicles, road conditions, skid marks, traffic controls, and any visible injuries. Collect the other driver's name, contact information, license plate number, and insurance details. Record the names and phone numbers of any witnesses.

Seek medical attention promptly. Even if you feel fine at the scene, see a doctor as soon as possible. Some injuries, including soft-tissue damage and concussions, do not produce obvious symptoms right away. A gap between the crash and medical care gives insurers an argument that the crash did not cause your injuries.

Report the crash to your insurer. Notify your own insurer to preserve your rights under any MedPay or UM/UIM coverage you carry. Be factual, and avoid giving a recorded statement about fault to the other driver's insurer until you understand your rights.

Do not accept a settlement offer without legal advice. The at-fault driver's insurer may move quickly with a low offer, especially for injuries that appear minor at first. Before you sign any release, consult a Missouri personal-injury attorney. A signed release closes your claim permanently, including for injuries that worsen over time. See the Missouri hit-and-run laws page for additional obligations if the other driver fled the scene.

This article is general legal information, not legal advice. Car accident law varies by state and changes, and settlement values depend on the specific facts. For advice about a specific crash, consult a licensed attorney in Missouri.
