State Requirements
Missouri operates under a traditional tort liability system, meaning at-fault drivers are responsible for damages they cause. The state requires all drivers to carry proof of insurance at all times and enforces compliance through the Missouri Department of Revenue's random verification program. Missouri also mandates uninsured motorist coverage at the same limits as your liability coverage, a requirement that distinguishes it from most other states.
Cost Overview
Missouri's average auto insurance costs fall slightly below the national median, but rates vary significantly based on location and coverage level. Urban areas like St. Louis and Kansas City see higher premiums due to elevated accident frequency, while rural counties with higher wildlife collision rates and longer emergency response times face different risk profiles.
What Affects Your Rate
- St. Louis County drivers pay 25–35% more than the state average due to elevated uninsured driver rates and accident frequency on I-270 and I-70.
- Kansas City metro rates run 20–30% above outstate Missouri, driven by theft rates in urban core neighborhoods and congestion on I-435.
- Drivers under 25 face premiums 60–90% higher than those aged 35–55, with male drivers under 21 seeing the steepest surcharges.
- A single at-fault accident raises premiums an average of 35–50% at renewal, while a DUI conviction can triple rates for three to five years.
- Rural Missouri counties including Ozark, Shannon, and Carter see higher comprehensive claims due to deer collisions, with November and October showing peak claim frequency.
- Credit-based insurance scores remain legal in Missouri and can influence premiums by 30% or more, though the state prohibits insurers from using credit as the sole basis for declination.

The foundation of Missouri's insurance requirement, covering bodily injury and property damage you cause to others. State minimums of 25/50/25 are often insufficient in serious accidents.
Full Coverage
Combines liability, collision, comprehensive, and uninsured motorist protection into a complete package. Recommended for vehicles worth more than $5,000 or when financing.
Comprehensive Coverage
Covers non-collision damage including theft, vandalism, hail, flooding, and animal strikes. Pays the actual cash value of your vehicle minus your deductible.
Uninsured Motorist Coverage
Required by default in Missouri, this coverage protects you when hit by a driver with no insurance or in a hit-and-run. Must match your liability limits unless rejected in writing.
Collision Coverage
Pays for damage to your vehicle from accidents with other vehicles or objects, regardless of who is at fault. Required by lenders on financed vehicles.
SR-22 Insurance
Not a coverage type but a certificate proving you carry minimum liability insurance, filed by your insurer with the Missouri Department of Revenue after certain violations.
