The deadline to file a car accident lawsuit in Missouri is five years — but waiting that long is a serious mistake. Here is what the statute of limitations actually means for your case, why it matters far earlier than most people expect, and when different deadlines apply.
After a car accident in Missouri, your most pressing concerns are likely your injuries, your vehicle, and getting your life back to normal. The legal deadline to file a lawsuit probably feels distant and abstract. But understanding Missouri’s statute of limitations is one of the most important things you can do to protect your right to compensation.
At Sotiriou Wilmowski Injury Law, we have seen clients lose their ability to pursue valid claims because they waited too long. We have also seen insurance companies exploit the complexity of these deadlines to pressure injured people into accepting far less than their cases are worth.
What Is a Statute of Limitations?
A statute of limitations is a law that sets the maximum amount of time you have to file a lawsuit after an event occurs. If you do not file within that window, the court will dismiss your case — no matter how strong your claim is, no matter how serious your injuries, and no matter how clearly the other driver was at fault.
Missouri’s Deadlines for Car Accident Claims
Personal injury: 5 years — Under RSMo § 516.120, you have five years from the date of the accident to file a lawsuit for personal injuries, including claims for medical expenses, lost wages, and pain and suffering.
Property damage: 5 years — Claims for vehicle damage and other personal property are also subject to a five-year deadline under RSMo § 516.120.
Wrongful death: 3 years — If a car accident caused someone’s death, Missouri law gives the surviving family members three years to file a wrongful death lawsuit under RSMo § 537.100.
Exceptions That Can Shorten Your Deadline
Claims Against Government Entities
If the accident involved a government vehicle, a government employee, or a dangerous condition on a government-owned road or property, you may be required to file a written notice of claim with the relevant government entity within 90 days of the accident. Failure to file this notice on time can bar your claim entirely — even if the general five-year window has not run.
Government entities include the City of St. Louis, St. Louis County, the Missouri Department of Transportation, and any municipality or state agency. If your accident involved a government vehicle or defective government road, contact an attorney immediately.
Minor Victims
If the accident victim is under 18, the statute of limitations does not begin to run until they turn 18 — giving them until their 23rd birthday to file. However, waiting is almost never advisable. Evidence fades, witnesses disappear, and insurance policies lapse.
Discovery Rule for Latent Injuries
In some cases where injuries are not immediately apparent, Missouri courts have applied a discovery rule that can delay the start of the limitations period. This rule does not apply automatically — contact an attorney to determine whether it applies to your situation.
Why the Five-Year Deadline Is Not a Safe Harbor
Critical evidence disappears fast. Surveillance footage from traffic cameras and nearby businesses is typically overwritten within 30 to 90 days. Skid marks fade within days. Black box data from the at-fault vehicle can be overwritten. Once we are retained, we immediately send evidence preservation letters — waiting months means that evidence simply no longer exists.
Witnesses move on. A witness with clear recall of the accident at the scene may, two years later, be unable to remember important details — or may be impossible to locate.
Insurance coverage changes. At-fault drivers change carriers. Policies lapse. Acting promptly ensures we can identify coverage before issues develop.
How Insurers Exploit the Statute of Limitations
Insurance adjusters know the statute of limitations. A common tactic: an adjuster will keep an accident victim engaged in negotiations — making low offers, requesting additional documentation, suggesting a settlement is just around the corner — until the limitations period expires or is about to expire. At that point, the victim has no leverage and no ability to file suit.
This is one of the reasons we advise clients not to negotiate directly with the insurance company without legal representation.
Illinois: Different Rules for Accidents Across the River
Many St. Louis-area residents live in Missouri but travel, work, or commute in Illinois. If your accident occurred in Illinois, different rules apply.
Personal injury in Illinois: 2 years (735 ILCS 5/13-202) — Illinois gives you only two years from the date of the accident, significantly less than Missouri’s five-year window. Accidents on I-55 in Madison County, Route 64 in St. Clair County, or anywhere else in Illinois fall under this shorter deadline.
Illinois also uses modified comparative fault — you cannot recover any compensation if you are found 51% or more at fault, compared to Missouri’s pure comparative fault system which allows recovery regardless of your fault percentage.
Frequently Asked Questions
Does filing an insurance claim stop the statute of limitations clock?
No. Filing a claim with an insurance company does not toll or extend the statute of limitations. Only filing a lawsuit in court preserves your right to litigate. An insurance claim and a lawsuit are entirely separate processes.
What if the at-fault driver died?
You can still pursue a claim against their estate and against their insurance carrier. Time limits still apply. Contact an attorney to navigate this situation.
What if I was partly at fault for the accident?
Missouri’s pure comparative fault rule allows you to recover even if you were partly at fault. Your compensation is reduced by your percentage of fault, but you are not barred from recovering.
I signed something at the accident scene. Did I waive my rights?
Information exchanged at the scene does not waive your legal rights. However, if you subsequently signed a settlement agreement or release with an insurance company, you may have resolved your claims. Contact an attorney to review any documents you have signed.
