What Is Uninsured Motorist Coverage Insurance?
Uninsured Motorist Coverage has two components: Bodily Injury (UMBI) covers your medical bills, rehabilitation, lost income if you still work part-time, and pain and suffering when hit by an uninsured driver. Uninsured Motorist Property Damage (UMPD) covers vehicle repairs when the at-fault driver has no insurance. For senior drivers, UMBI is particularly valuable because age-related factors — bone density, healing time, pre-existing conditions — mean accident injuries cost significantly more to treat and take longer to resolve, even with Medicare. A broken hip at 70 has different recovery implications than at 40, and this coverage fills gaps Medicare doesn't address.
How Much Does Uninsured Motorist Coverage Insurance Cost?
- State uninsured motorist rate — states with 15-20% uninsured drivers charge significantly more than states with 5-8%
- Coverage limits selected — $100,000/$300,000 UMBI costs roughly double what $25,000/$50,000 costs
- Whether you stack coverage — stacking UMBI across multiple vehicles on one policy increases cost but also protection
- Local area — urban counties with higher uninsured rates and accident frequency cost more than rural areas
- Your liability limits — insurers often tie UMBI limits to your liability limits, so higher liability coverage can raise UMBI cost
- Claims history — a prior UMBI claim can increase cost at renewal, though less dramatically than an at-fault accident
