What Is Uninsured Motorist Coverage Insurance?
Uninsured Motorist Coverage has two components: bodily injury (UM/UIM-BI) covers your medical bills, lost income, and pain and suffering when an at-fault driver has no insurance or insufficient limits, while property damage (UM/UIM-PD, available in some states) covers vehicle repair or replacement. For senior drivers, the bodily injury component is especially critical because age-related injury severity means a minor collision can result in hip fractures, longer recovery times, and medical bills Medicare doesn't fully cover — particularly emergency transport, specialist care, and rehabilitation. This coverage also applies to hit-and-run accidents where the other driver is never identified, a scenario that leaves you with no one to pursue for damages.
How Much Does Uninsured Motorist Coverage Insurance Cost?
- State uninsured motorist rate — states with higher percentages of uninsured drivers (Mississippi, New Mexico, Michigan) charge more for this coverage, sometimes $25–$35 monthly for seniors
- Coverage limits selected — raising bodily injury limits from $50,000/$100,000 to $100,000/$300,000 typically adds $6–$12 monthly for senior drivers
- Whether coverage is stacked or unstacked — stacked coverage (combining limits across multiple vehicles) costs 15–30% more but provides higher protection for multi-car senior households
- Bundling with liability insurance — most insurers price UM/UIM as a percentage of your liability limits, so seniors carrying higher liability coverage pay proportionally more for uninsured motorist protection
- Deductible selection for property damage — choosing a $500 deductible versus $250 can reduce the property damage component by $3–$5 monthly for senior drivers
- ZIP code accident frequency — seniors living in urban areas with higher hit-and-run rates pay 20–40% more than those in rural areas with lower uninsured driver concentrations
