Uninsured Motorist Coverage Explained

Nearly 13% of drivers on American roads are uninsured, and another significant percentage carry only minimum insurance that may not fully cover your damages. Uninsured Motorist (UM) and Underinsured Motorist (UIM) coverage protects you when an at-fault driver can't pay for the damage they cause.

What is Uninsured Motorist Coverage?

Uninsured Motorist coverage pays for your injuries, lost wages, and vehicle damage when you're in an accident caused by a driver without insurance. It comes in two types:

What is Underinsured Motorist Coverage?

Underinsured Motorist (UIM) coverage kicks in when the at-fault driver has insurance, but their liability limits aren't enough to cover your full damages. For example, if you have $50,000 in medical bills but the at-fault driver only has $25,000 in coverage, UIM would pay the $25,000 difference.

Important to Know

Many insurance policies combine UM and UIM into a single coverage called UM/UIM. This provides comprehensive protection regardless of the other driver's insurance status.

Coverage Limits and How They Work

UM/UIM coverage limits are expressed the same way as liability coverage (e.g., 100/300). The first number is the per-person limit, and the second is the per-accident limit.

Important Limitation: Your UM/UIM coverage cannot exceed your liability coverage limits. If you have 50/100 liability, you can't carry more than 50/100 UM/UIM.

Matching Your Liability Limits

Insurance experts recommend carrying UM/UIM limits equal to your liability coverage. If you have 250/500 liability, get 250/500 UM/UIM for comprehensive protection.

State Requirements

UM/UIM requirements vary significantly by state:

Even if your state doesn't require UM/UIM, it's highly recommended. The cost is relatively low compared to the protection it provides.

How Claims Work

Filing an uninsured motorist claim:

  1. Report the Accident: Call police immediately and file a report
  2. Document Everything: Get witness information, photos, and medical records
  3. Notify Your Insurer: File a claim with your own insurance company
  4. Prove the Other Driver is Uninsured: Your insurer will verify the other driver's insurance status
  5. Claim Settlement: Your insurance company pays based on your UM/UIM limits

Cost of UM/UIM Coverage

Uninsured motorist coverage is surprisingly affordable, typically adding only $50-150 per year to your premium. The exact cost depends on:

UM/UIM vs. Collision Coverage

Many people wonder if they need both. The answer is yes, because they serve different purposes:

Special Situations

Hit-and-Run Accidents

UM coverage typically applies to hit-and-run accidents where the at-fault driver can't be identified. Some states require you to report hit-and-runs within a specific timeframe (often 24 hours) to qualify for UM coverage.

Out-of-State Accidents

Your UM/UIM coverage generally follows you when driving in other states, but coverage may adjust to meet the minimum requirements of the state where the accident occurs.

Stacking vs. Non-Stacking

In some states, you can "stack" UM/UIM coverage if you insure multiple vehicles:

Conclusion

Uninsured and underinsured motorist coverage is one of the most important—and most overlooked—components of auto insurance. With millions of uninsured drivers on the road, protecting yourself is essential. The relatively low cost makes UM/UIM coverage one of the best values in auto insurance.

Don't assume the other driver has adequate insurance. Protect yourself, your family, and your finances by carrying robust UM/UIM coverage equal to your liability limits.
