Uninsured/underinsured motorist (UM/UIM) coverage pays for your property damage and bodily injuries if an at-fault driver doesn’t have any or enough insurance to cover damages. While some states require drivers to carry UM/UIM coverage, it’s optional in most states.
Since UM/UIM insurance rates are typically inexpensive, consider adding coverage if your state doesn’t require it. Otherwise, you may be left with significant out-of-pocket expenses if you’re hit by a driver without enough insurance.
Keep reading to learn more about uninsured/underinsured motorist property damage and bodily injury coverage.
- Uninsured/underinsured motorist insurance covers damages and injuries if you’re hit by a driver with little to no coverage
- Some states require UM/UIM coverage, but most don’t
- Uninsured/underinsured motorist insurance rates are typically inexpensive
What Uninsured/Underinsured Motorist Insurance Covers
Uninsured and underinsured motorist coverage offers protection if a driver who hits you doesn’t have enough insurance to cover damages and injuries. Only 17 states require UM/UIM coverage.
Uninsured motorist coverage kicks in if the at-fault driver has no insurance. For example, if another driver hits you and doesn’t have insurance, your uninsured motorist insurance pays for damages and injuries.
Underinsured motorist coverage pays for damages and injuries if the at-fault driver’s coverage limits aren’t high enough. For example, if a driver hits you and only has the state-mandated liability coverage of $10,000 and your vehicle damage is $15,000, your insurance pays the remaining $5,000.
However, your uninsured/underinsured motorist coverage has limits, so make sure you have enough coverage to pay for property damage and bodily injury if a driver without enough coverage hits you.

Uninsured/Underinsured Motorist Insurance vs. Other Coverage
There are many types of car insurance, so knowing your needs is essential. This table shows car insurance coverages available and whether or not they are required.
Car Insurance Coverage Type Comparison
| Coverage Type | Description | Requirements |
|---|---|---|
| Bodily Injury (BI) | Covers injuries to others caused by the policyholder while operating an automobile | Often $25,000/$50,000 or higher |
| Collision | Covers damages to your vehicle from a collision with another car or object | Optional but may be required by lenders |
| Comprehensive | Covers non-collision-related damages to your car from events like natural disasters, theft, vandalism, fire, or animal collisions | Optional but may be required by lenders |
| Emergency Road Service | Provides services like fuel delivery, lock-outs, jump-starts, flat tire changes, and towing | Optional |
| Gap Insurance | Pays the difference between the vehicle's actual cash value and the outstanding balance on your loan or lease when a car is totaled | Optional |
| Medical Payments (MedPay) | Covers medical or funeral expenses for you and passengers after an accident, regardless of fault | Optional in many states |
| Personal Injury Protection (PIP) | Covers medical expenses, lost wages, and other damages for you and your passengers, regardless of fault | Required in no-fault states |
| Property Damage (PD) | Covers damages to someone else's property caused by the policyholder, including vehicles, buildings, or other properties | Often $10,000 or higher |
| Rental Reimbursement | Covers the cost of a rental car during repairs due to a covered accident | Optional |
| Underinsured Motorist (UIM) | Pays for damages when the other driver's liability limits aren't sufficient to cover your medical expenses | Varies; some states require this coverage |
| Uninsured Motorist (UM) | Covers injuries to the policyholder or passengers caused by uninsured drivers | Varies; some states require this coverage |
Each state decides which coverages are mandatory. While most states require liability coverage, UM/UIM state laws vary. Even if your state doesn’t require UM/UIM coverage, it’s still smart to add it to your policy.
Although full coverage car insurance isn’t required, many drivers choose a policy that includes liability, collision, comprehensive, and other mandated coverages, such as UM/UIM.
Uninsured/Underinsured Motorist Insurance Benefits
The benefit of adding uninsured/underinsured motorist coverage is that you won’t have to pay for damages and injuries yourself. If the at-fault driver has minimum or no insurance, your vehicle damage and bodily injuries won’t be covered.
Without UM/UIM coverage, you would have to pay for those repairs and expenses yourself. UM/UIM coverage ensures that your insurance company pays for your damages if the other driver can’t.

Keep in mind that you set the UM/UIM limits on your policy, so be sure to carry enough coverage to pay for vehicle damage and medical expenses in case another driver doesn’t have enough coverage.

How to File an Uninsured/Underinsured Motorist Insurance Claim
The car insurance claims process differs for uninsured/underinsured motorist coverage. While some parts are the same, such as documenting damages, filing a police report, and contacting your insurer, other aspects are different.
For example, if you’re hit by an uninsured driver, only your insurance company is involved in settling the claim. Claims would be covered under your uninsured motorist coverage.
The uninsured motorist bodily injury portion of your coverage pays for medical bills, pain and suffering, and other injury-related costs. The uninsured motorist property damage coverage pays for damage to your car or other property. However, your insurance only pays up to your policy limits.
In an underinsured motorist example, the at-fault driver’s insurance pays up to their policy limits. Then, your underinsured motorist coverage kicks in.
How to Buy Uninsured/Underinsured Motorist Insurance Coverage
Uninsured/underinsured motorist insurance pays for your damages and injuries if the at-fault driver doesn’t have enough coverage. Although some states require UM/UIM coverage, most states don’t. Consider adding UM/UIM insurance to be better protected.

Frequently Asked Questions
What is the difference between uninsured and underinsured motorist coverage?
Uninsured motorist coverage kicks in if the at-fault driver doesn’t have any auto insurance. Underinsured motorist coverage comes in when the at-fault driver doesn’t have enough coverage to pay for damages and injuries. In both cases, your insurance would pay for anything the other driver’s insurance didn’t cover.
What states require uninsured/underinsured motorist insurance coverage?
States that require UM/UIM include Connecticut, Illinois, Kentucky, Maine, Maryland, Minnesota, Nebraska, New Jersey, New York, North Carolina, North Dakota, Oregon, South Carolina, South Dakota, Vermont, Virginia, and West Virginia.
How much uninsured/underinsured motorist insurance coverage do I need?
Typically, you’ll want to at least match your property damage and bodily injury liability coverage. Some states set UM/UIM coverage requirements.
Do I need uninsured/underinsured motorist insurance coverage if I have health insurance?
Yes, you need UM/UIM coverage even if you have health insurance. This coverage pays for lost wages and pain and suffering, and health insurance does not. In addition, if you lose your job, your health insurance may be lost as well.
Does uninsured/underinsured motorist insurance cover hit-and-runs?
Uninsured/underinsured motorist coverage may pay for hit-and-run damages and injuries. Your insurance pays for claims even if the at-fault driver can’t be found.
What happens when an uninsured driver hits your car?
If an uninsured driver hits your car, follow the usual procedures for filing a claim. Your insurance company pays for damages and medical bills up to your coverage limit.
Do uninsured motorist claims raise car insurance rates?
Filing an uninsured motorist claim may raise your insurance rates even though you aren’t at fault. Carefully consider whether it’s cheaper to pay for repairs yourself rather than a higher insurance rate.
How much can I get from an uninsured motorist claim?
The amount you receive from an uninsured motorist claim depends on your policy limit. Since your insurance company is the one that pays, it only pays out up to the policy limit. Damages above the limit would be paid by you out of pocket.
What is the difference between stacked and unstacked uninsured motorist coverage?
Stacked uninsured motorist coverage combines limits from several policies or vehicles to increase the maximum payout. Unstacked uninsured motorist coverage can’t be combined with other policies or vehicles.
Why is uninsured motorist coverage so expensive in Florida?
Florida has a very large percentage of uninsured motorists, so you’re more likely to be in an accident with a driver who doesn’t have insurance. Since the insurance company is more likely to pay out an uninsured motorist claim, they charge higher coverage rates.
