What Is Uninsured Motorist Coverage Insurance?
Uninsured Motorist Coverage (UM) pays for your injuries and, in most states, your vehicle damage when an at-fault driver has no insurance, carries less than your policy limits (underinsured motorist coverage), or flees the scene in a hit-and-run. It comes in two parts: Uninsured Motorist Bodily Injury (UMBI) covers medical bills, lost wages, and pain and suffering for you and your passengers, while Uninsured Motorist Property Damage (UMPD) covers repairs to your vehicle. Critically, this coverage works even if you only carry liability insurance — you don't need collision or comprehensive coverage for UM to apply.
How Much Does Uninsured Motorist Coverage Insurance Cost?
- Coverage limits — choosing $25,000/$50,000 UMBI costs significantly less than $100,000/$300,000 limits, but leaves larger gaps if you're hit by an uninsured driver with serious injuries.
- State uninsured driver rate — states like Florida, New Mexico, and Mississippi with uninsured rates above 20% typically charge higher UM premiums due to increased claim frequency.
- UMPD deductible — some states allow you to choose a deductible on Uninsured Motorist Property Damage (typically $250 to $500), which lowers your premium but increases out-of-pocket costs after an accident.
- Whether you bundle UMBI and UIM — Underinsured Motorist Coverage is usually sold alongside UM as a combined endorsement, adding approximately $3 to $8 more per month depending on limits.
- Urban vs. rural location — drivers in densely populated metro areas typically pay 15–30% more for UM coverage due to higher accident rates and greater likelihood of encountering uninsured motorists.
