Minimum Liability Requirements

Missouri law requires drivers to carry minimum liability limits of $25,000 for bodily injury per person, $50,000 for bodily injury per accident, and $15,000 for property damage. These thresholds apply to all insured vehicles and must be maintained in all circumstances, including when the vehicle is in the owner's possession, parked, or under loaner or rental arrangements.

Additional Coverage Options

While the state mandates only liability, insurers offer supplemental coverages that address gaps:

  • Uninsured/Underinsured Motorist (UIM) – protects against drivers lacking adequate insurance.
  • Medical Payments (MedPay) – covers medical expenses regardless of fault.
  • Collision and Comprehensive – optional but recommended for vehicle protection.

Statutory Provisions and Enforcement

Key statutes governing Missouri auto insurance include:

StatuteKey Provision
Miss. Stat. Ann. § 443.140Defines minimum liability limits and penalties for non‑compliance.
Miss. Stat. Ann. § 443.145Mandates UIM coverage for all drivers, with a minimum of $25,000 per person.
Miss. Stat. Ann. § 443.150Outlines the insurer's duty to investigate claims within 30 days.

Claims Process and Dispute Resolution

When a claim arises, the insurer must:

  • Accept the claim within 30 days of receipt.
  • Provide an estimate of damages within 30 days of investigation.
  • Offer a settlement within 90 days if the claim is valid.

Drivers dissatisfied with a settlement can file a complaint with the Missouri Department of Insurance (MDI) or pursue legal action in state court. The MDI maintains a public docket and offers mediation services to resolve disputes before litigation.

Insurance Fraud and Penalties

Missouri criminalizes insurance fraud under Miss. Stat. Ann. § 443.160. Penalties include fines up to $5,000, imprisonment up to five years, and revocation of the insurer's license. Insurers must report suspected fraud to the MDI's Fraud Unit, which investigates and coordinates with law enforcement.

Recent Legislative Updates

In 2021, Missouri enacted a bill requiring insurers to report annual loss ratios and claim payouts to the MDI. The data aims to improve market transparency and detect abnormal loss patterns that may signal systemic fraud or pricing abuses.

Practical Tips for Missouri Drivers

  • Verify policy limits with the insurer and ensure they match state minimums.
  • Consider UIM and MedPay coverage, especially if you share a vehicle with others.
  • Keep all documentation—police reports, medical bills, and repair estimates—organized for quick claim filing.
  • Review the insurer's claims process in the policy handbook to understand timelines and responsibilities.
