What Is Uninsured Motorist Coverage Insurance?
Uninsured Motorist Coverage has two components: bodily injury (UMBI) and property damage (UMPD). UMBI pays for your medical bills, lost wages, and pain and suffering when an uninsured or underinsured driver causes an accident that injures you or your passengers. UMPD covers damage to your vehicle when the at-fault driver has no insurance. Some states bundle underinsured motorist protection automatically, which kicks in when the other driver's liability limits are too low to cover your full losses.
How Much Does Uninsured Motorist Coverage Insurance Cost?
- Your coverage limits: $25,000/$50,000 costs significantly less than $100,000/$300,000 in bodily injury protection.
- State uninsured motorist rate: High-uninsured states like Mississippi or Michigan see higher premiums due to elevated claim frequency.
- Whether you add UMPD: Adding property damage coverage increases cost by $3 to $8 per month depending on your deductible choice.
- Stacking vs. non-stacking: Stacked coverage, which multiplies limits across multiple vehicles on your policy, costs 15% to 40% more than non-stacked.
- Your liability limits: Insurers often tie UM limits to your liability coverage, so higher liability limits may require higher UM limits.
- Urban vs. rural location: Urban drivers typically pay more due to higher accident rates and uninsured driver concentrations.
