What Is Uninsured Motorist Coverage Insurance?
Uninsured Motorist Coverage has two components: Uninsured Motorist Bodily Injury (UMBI) pays for medical bills, lost income, pain and suffering, and rehabilitation costs when an uninsured driver injures you or your passengers. Uninsured Motorist Property Damage (UMPD) covers repair costs to your vehicle after an at-fault uninsured driver hits you. For senior drivers, UMBI is particularly valuable because age-related factors often mean longer hospital stays, more physical therapy sessions, and complications that Medicare doesn't cover for auto accidents — such as deductibles, co-pays for specialists, and non-emergency transportation to medical appointments. Hit-and-run accidents are also covered under this policy, which matters for seniors who may park in less-supervised areas or drive during off-peak hours when witnesses are scarce.
How Much Does Uninsured Motorist Coverage Insurance Cost?
- State uninsured motorist rate — states with higher percentages of uninsured drivers (Mississippi, Michigan, Tennessee) charge more for this coverage
- Coverage limits selected — $50,000/$100,000 UMBI costs significantly less than $250,000/$500,000 limits, and seniors with substantial retirement assets may want higher limits to protect those assets
- Whether you bundle UMBI and UMPD or purchase separately — bundled policies typically cost 15–20% less
- Stacking vs. non-stacking coverage — stacking allows you to combine limits across multiple vehicles on your policy for a single claim, increasing cost by 20–35% but providing more protection for serious injuries
- Your ZIP code's accident and uninsured driver claim history — urban areas and neighborhoods with higher uninsured driver rates see premium increases of 25–40%
- Credit-based insurance score in states where it's permitted — seniors with excellent credit often receive 10–15% lower rates on all coverage types including uninsured motorist
