What Is Uninsured Motorist Coverage Insurance?
Uninsured Motorist Coverage has two components: Bodily Injury (UMBI) pays your medical bills, lost wages, and pain and suffering when an at-fault driver has no insurance or insufficient coverage, and Property Damage (UMPD) covers your vehicle repairs in the same scenario. If you're hit by someone who fled the scene (hit-and-run), UM coverage typically steps in as if the phantom driver had no insurance. The coverage pays up to your policy limits, not the other driver's nonexistent limits — so if you carry $50,000/$100,000 UMBI and sustain $75,000 in medical costs from an uninsured driver, you receive $50,000 from your own policy.
How Much Does Uninsured Motorist Coverage Insurance Cost?
- Your UM coverage limits — higher limits (e.g., $100,000/$300,000 vs. $25,000/$50,000) increase cost proportionally, often by 30–60%.
- State uninsured motorist rate — if you live in a state where 15–20% of drivers are uninsured (like Florida, Mississippi, or New Mexico), insurers price UM coverage higher to reflect increased claim likelihood.
- Your ZIP code's hit-and-run frequency — urban areas with higher rates of phantom vehicle claims see UM premiums 20–40% above rural areas.
- Whether you stack coverage — in states that allow stacking, combining UM limits across multiple vehicles on your policy increases both protection and cost significantly.
- Your overall risk profile — drivers with DUIs, at-fault accidents, or SR-22 requirements already pay elevated base premiums, but UM coverage cost as a percentage of total premium often stays consistent or even drops slightly since UM claims aren't tied to your own driving behavior.
- Deductible selection for UMPD — choosing a $500 deductible instead of $250 can reduce UMPD cost by 15–25%, though many states don't allow deductibles on UMBI.
