How to File an Uninsured Motorist Claim in Missouri: Limits, Timelines, and Exclusions

Current as of: October 2, 2026 Car Accidents & Collisions Missouri
In Missouri, Uninsured Motorist (UM) coverage is mandatory. If you are hit by a driver without insurance, your own policy will cover your medical bills up to your policy limits, which must be at least $25,000 per person. Acting quickly to report the crash is crucial to protecting your rights.

Being involved in a car crash is stressful enough, but discovering the at-fault driver has no insurance can turn that stress into full-blown panic. Fortunately, Missouri law anticipates this exact problem. Every auto insurance policy issued in the state must include Uninsured Motorist (UM) coverage. This means your own insurance company steps into the shoes of the uninsured driver to pay for your bodily injuries, lost wages, and pain and suffering.

However, simply having UM coverage does not mean your insurance company will automatically write you a check. They will investigate your claim just as aggressively as they would investigate a claim against someone else. To navigate the complexities of policy limits, timelines, and insurance bad faith, utilizing our directory to find a skilled Missouri car accident lawyer can make all the difference in your financial recovery.

Missouri's Mandatory UM Limits and Timelines

Under Mo. Rev. Stat. § 379.203, Missouri requires all drivers to carry a minimum of $25,000 per person and $50,000 per accident in Uninsured Motorist bodily injury coverage. It is important to note that standard UM coverage in Missouri applies only to bodily injury, not property damage. Unless you specifically purchased Uninsured Motorist Property Damage (UMPD) or standard collision coverage, you may be responsible for your vehicle repair costs.

When it comes to timelines, a lawsuit against your insurer for UM benefits is an action upon a writing for the payment of money and is governed by a 10-year statute of limitations under Mo. Rev. Stat. § 516.110, as established in Oates v. Safeco Ins. Co. of Am., 583 S.W.2d 713 (MO Supreme Court 1979) (the 5-year tort deadline under Mo. Rev. Stat. § 516.120 applies only to suing the at-fault driver directly). However, your specific insurance policy will dictate a much shorter timeline to initially report the accident. Most policies require you to notify them within 30 days, and in cases of a hit-and-run, some require a police report to be filed within 24 hours.

Handling 'Phantom Vehicle' Hit-and-Runs

One of the most complex UM claims involves a 'phantom vehicle'-a driver who causes a crash and flees the scene before you can identify them. In Missouri, insurance companies are notoriously suspicious of these claims because they fear a driver simply ran off the road on their own and invented a story about another car to avoid a premium hike.

Under Mo. Rev. Stat. § 379.203.1, Missouri law explicitly guarantees that uninsured motorist coverage applies whether or not physical contact was made between the vehicles. In the landmark case Dawson v. Denney-Parker, 967 S.W.2d 90 (MO Court of Appeals 1998), the court held that policy provisions requiring physical contact for hit-and-run accidents are void as contrary to public policy. Even if there was no contact (such as swerving to avoid an oncoming vehicle and crashing), your insurer cannot deny your UM claim simply because your vehicle never touched the phantom vehicle, though securing corroborating evidence like eyewitness testimony, 911 audio, or dashcam footage remains essential to prove the other driver caused the crash.

What to Do if the At-Fault Driver Lies About Their Coverage

It is incredibly common for drivers in St. Louis, Kansas City, and Springfield to present a fake or expired insurance card at the scene of the crash. You might leave the scene believing you have a standard liability claim, only to receive a letter weeks later from the named insurance company stating the policy was canceled for non-payment.

As soon as you receive a denial of coverage letter from the at-fault driver's supposed insurer, you must immediately pivot to a UM claim. You should file Form 1140, Missouri, Department of Revenue, Motor Vehicle Accident Report with the Missouri Department of Revenue, Jefferson City to officially document that the other driver lacked valid insurance, which can also trigger state penalties against their driving privileges.

Dealing with Stolen Vehicles Causing Crashes

If a car thief steals a vehicle and subsequently rear-ends you on I-70, you cannot usually sue the vehicle's actual owner. Auto insurance follows the car, but only when it is being operated with 'permissive use'. Because a thief does not have permission to drive the car, the owner's insurance company will rightfully deny liability coverage.

In this scenario, the stolen vehicle is legally treated as an uninsured vehicle. Your own UM coverage is your primary path to compensation for your medical bills. You will need the police report proving the vehicle was reported stolen prior to the crash to satisfy your insurance adjuster's requirements.

Step-by-Step Guide to Filing Your UM Claim

Follow these steps to protect your claim against your own insurance company.

Step 1: Call the Police Immediately

Never let an uninsured driver talk you out of calling the police. A formal crash report from the Missouri State Highway Patrol or local police is mandatory for a successful UM claim.

Step 2: Seek Medical Treatment

Your UM policy pays for bodily injury. You must prove you were injured by going to the emergency room or an urgent care clinic immediately after the crash. Gaps in treatment will be used by your insurer to devalue your claim.

Step 3: Notify Your Insurer in Writing

Call your insurance agent to report the crash, but follow up in writing. State clearly that the other driver was uninsured or fled the scene, and that you intend to open an Uninsured Motorist claim.

Step 4: Consult a Lawyer Before Giving a Statement

Your insurance company is not your friend in a UM claim; they are functioning as the defense for the uninsured driver. Before providing a recorded statement, consult an attorney. If your insurer acts in bad faith, your lawyer can file a lawsuit in your local court, such as the Jackson County Circuit Court, Kansas City or the St. Louis City Circuit Court, St. Louis.

How Much Does it Cost to Hire a Lawyer?

Handling a UM claim generally costs you nothing out of pocket.

  • Contingency Fees: Personal injury lawyers in Missouri work on a contingency fee basis. They take a percentage (usually 33% to 40%) of the final UM settlement. If they don't win your case, you owe them zero legal fees.
  • Filing Fees: If a lawsuit against your insurer is required, civil filing fees in Missouri are generally between $150 and $250, which your lawyer will typically advance on your behalf.

Frequently Asked Questions (FAQ)

Will filing a UM claim raise my insurance rates?

Under Missouri law, insurance companies are generally prohibited from raising your premiums solely because you filed an Uninsured Motorist claim for an accident that was not your fault.

Can I stack my UM policies in Missouri?

Yes. Missouri public policy strongly favors the 'stacking' of Uninsured Motorist policies. If you have three cars insured on the same policy with $25,000 UM limits on each, you can potentially stack them for a total of $75,000 in available coverage.

What if the at-fault driver has some insurance, but not enough?

If the at-fault driver's insurance limits are lower than your medical bills, you would file an Underinsured Motorist (UIM) claim, not a UM claim. UIM coverage is optional in Missouri, so you must check your policy declarations page to see if you purchased it.

What do I do if my insurance company denies my UM claim?

If your insurer unfairly denies your claim, you can file a Consumer Complaint Form with the Missouri Department of Commerce and Insurance, Jefferson City. Additionally, you should hire an attorney to file a breach of contract and vexatious refusal to pay lawsuit against them.
