Uninsured/Underinsured Motorist Coverage: Protects You When Others Can’t Pay
Not every driver on the road has enough insurance—or any at all. This coverage steps in if you’re hit by someone without adequate coverage, so you don’t pay out-of-pocket for their mistake.
When Uninsured/Underinsured Motorist Coverage Makes the Difference
Real scenarios that show exactly when and how uninsured/underinsured motorist coverage protects you.
Hit in a Parking Lot
Alex was parked at a grocery store when another driver bumped his car and then admitted having no insurance. Alex’s uninsured motorist coverage responded immediately, handling the $2,500 repair bill. Instead of lengthy disputes and paying out of pocket, Alex only paid his $500 deductible and was back on the road the next day.
Injured by an Underinsured Driver
Maria was rear-ended at a stoplight by a driver with only the minimum required insurance. Her medical bills and missed work quickly exceeded the at-fault driver’s limits. Maria’s underinsured motorist coverage covered an additional $13,000 in costs, so she could recover without financial strain. Her only out-of-pocket expense was her $1,000 deductible, allowing Maria to focus on healing, not bills.
Serious Hit-and-Run Accident
The Nguyen family was struck in a hit-and-run accident on their way home, sustaining both vehicle damage and injuries. The responsible driver was never found. Their uninsured motorist coverage covered $54,000 in vehicle repairs and medical bills. Without this coverage, the Nguyens would have faced devastating financial losses. The family paid their deductible and had full access to care and recovery support.
Uninsured/Underinsured Motorist Coverage Explained: The Details That Matter
The complete picture: what's covered, what's not, and how to decide if you need it.
Uninsured/Underinsured Motorist Coverage (Plain English)
Uninsured/Underinsured Motorist Coverage steps in when another driver causes an accident but doesn't have enough (or any) insurance. When this happens, this coverage pays for your car repairs, medical bills, and related costs up to your selected limit. The key thing to understand is that it protects you and your passengers from financial loss when someone else can’t pay.
The Fine Print
Your deductible applies, just like other parts of your auto insurance—typically $500 to $1,000. Coverage limits must be chosen when you buy or update your policy. Your coverage pays actual injury or repair costs, up to your selected limits. These limits cannot exceed your liability limits for bodily injury and property damage. In some cases, coverage only applies if the other driver is identified (varies by circumstance).
Uninsured/Underinsured Motorist vs. Other Coverages
Uninsured/Underinsured Motorist Coverage is NOT the same as Liability Coverage. Uninsured/Underinsured Motorist Coverage covers your injuries and damages when the other driver can’t pay, while Liability Coverage pays for others’ injuries or damages if you cause the accident. You typically need both to be fully protected.
Who Needs Uninsured/Underinsured Motorist Coverage?
You typically need this coverage if:
- You are regularly driving and want to avoid out-of-pocket costs from uninsured drivers
- Your car is important for work or family and you can’t afford to go without it
You might skip this coverage if:
- Your car is rarely driven or not valuable
Limits and Options
You choose coverage limits—usually the same as your liability coverage (for example, $50,000 per person / $100,000 per accident). Deductible options vary; common choices are $500 or $1,000. Higher limits mean better protection but may raise your premium slightly. Some policies offer stacking options in Colorado, increasing protection if you have multiple insured cars.
What's NOT Covered by Uninsured/Underinsured Motorist Coverage
This coverage does NOT cover:
- Your injuries as the at-fault driver: It’s for when someone else causes the accident.
- Damage caused by natural disasters or theft: That’s covered by Comprehensive Coverage.
For these situations, you’d need collision or comprehensive coverage.

How Uninsured/Underinsured Motorist Coverage Actually Works
Understanding exactly what happens when you file an uninsured/underinsured motorist claim—start to finish.
The Claims Process
- Report the Incident: Contact your insurance company right away—provide details of the accident and the other party's information (if known).
- Investigation & Documentation: Your insurer reviews your coverage, gathers police reports, medical info, and assesses whether the other driver was uninsured or underinsured.
- Claim Review & Approval: If the claim is covered, the adjuster confirms repair or medical claim amounts within your policy limits.
- Resolution: You pay your deductible, then receive payment for repairs, medical bills, or lost wages. Your insurer may recover costs from the at-fault party if possible.
What You Pay
Your deductible—typically $500 to $1,000—applies before insurance pays the rest. Your premium covers this valuable protection. Higher deductibles lower your premium, but be sure you can pay your deductible out of pocket if needed.
Timeline
Simple uninsured claims can resolve in a week or two, while serious injuries or hit-and-run cases may take several weeks or longer for investigation and documentation. Most customers find the process straightforward. The key is prompt reporting: the sooner you start, the faster your claim can be resolved.

The math is simple: coverage pays for itself the first time you need it and helps protect your financial future.
4 Costly Uninsured/Underinsured Motorist Coverage Mistakes to Avoid
Learn from others' mistakes—avoid these common errors that can leave you unprotected when you need coverage most.
Assuming Everyone Else Is Properly Insured
Many drivers believe insurance is universal, but as many as 1 in 8 vehicles on the road are uninsured. Counting on others can leave you with major bills. Instead, secure your own protection and review your policy annually.
Choosing Bare Minimum Limits
It's tempting to pick the lowest legal requirement to save a few dollars, but medical costs and repair bills quickly exceed low limits. Insufficient limits can force you to pay large expenses yourself. Instead, choose limits that reflect your actual risk—not just what’s required by law.
Thinking Your Health Insurance or Collision Will Cover It All
Many assume their health or collision coverage will replace uninsured/underinsured protection. But these only handle parts of the risk. Instead, make sure your protection matches the whole range of consequences, including lost wages and pain/suffering.
Forgetting to Update Coverage With Life Changes
As your household, vehicle value, or financial needs change, your coverage should too. Outdated limits or missed add-ons can leave you exposed. Instead, review your coverage every year or after major life events—like a new car or driver in the household.
