Uninsured motorist (UM) insurance is a type of car insurance coverage that protects you if you're in an accident with a driver who doesn't have liability insurance. According to the Insurance Information Institute, approximately 13% of drivers on U.S. roads are uninsured. This means millions of people could be hit by someone without insurance protection. Uninsured motorist coverage helps pay for your medical bills, lost wages, and vehicle damage when this happens.

When an uninsured driver causes an accident, your UM coverage steps in where their insurance would normally pay. For example, if an uninsured driver runs a red light and hits your car, causing $15,000 in damage and $8,000 in medical bills, your UM coverage would cover these costs up to your policy limits. Most states require or strongly recommend this coverage because accidents with uninsured drivers are relatively common.
UM insurance typically covers bodily injury, which includes medical treatment, rehabilitation, pain and suffering, and lost income from time off work. Property damage coverage under UM insurance pays for repairs or replacement of your vehicle. Some policies also cover hit-and-run accidents where the other driver flees the scene and cannot be identified.
The coverage has limits set when you purchase your policy. For instance, you might choose a $25,000 per person limit and a $50,000 per accident limit. If your damages exceed these limits, you would be responsible for the remaining costs. Understanding what your specific policy covers requires reading your insurance documents or discussing coverage details with your insurance agent.
Practical Takeaway: Review your current auto insurance policy documents to see what UM coverage limits you have. If you don't have UM coverage, learning about this protection helps you understand a gap in your insurance that could affect you financially after an accident.
Filing a claim for uninsured motorist coverage involves specific steps and timelines that vary by insurance company and state. The process typically begins immediately after an accident. First, you should contact law enforcement and obtain a police report, which documents the accident and ideally identifies the other driver. This report becomes important evidence for your claim because it establishes that the other party was at fault and uninsured.

After the accident, you need to contact your insurance company as soon as possible. Most insurance policies require you to report accidents within a certain timeframe, often 30 days, though reporting sooner is better. When you call your insurer, have the police report number, the other driver's information (if available), photos of damage, and names of any witnesses ready to share.
Your insurance company will assign a claims adjuster to investigate your claim. The adjuster reviews the police report, photographs, repair estimates, medical records, and other evidence. In hit-and-run cases, the investigation may take longer since the other driver's information isn't available. The adjuster determines the value of your claim based on the actual damages and your policy limits.
If your claim is approved, your insurance company will pay according to your coverage limits. You may receive payment for medical bills that have already been paid, or the payment may go directly to medical providers, repair shops, or your bank account depending on your policy and claim circumstances. Some claims are settled quickly, while others involving serious injuries or significant damage may take weeks or months.
In some cases, insurance companies may deny claims if they find that the other driver actually had insurance but failed to provide it, or if the accident circumstances don't match the policy's coverage terms. You have the right to dispute a denial and request a review of the decision.
Practical Takeaway: After any accident, gather the police report number and contact information from witnesses. Save documentation of all medical treatment and repair costs. This information will be needed when you contact your insurance company to file your claim.
Uninsured motorist insurance requirements differ across the United States. As of recent data, 21 states require UM coverage for all drivers, while 28 states allow drivers to decline it if they choose. Three states have no specific UM requirements. Understanding your state's rules matters because it affects what coverage you must have and what options are available to you.

In states where UM coverage is required, you typically cannot decline it unless you sign a written waiver. For example, New York requires uninsured motorist coverage with minimum limits of $25,000 for bodily injury per person and $50,000 per accident. California requires $15,000 per person and $30,000 per accident. Texas allows drivers to reject UM coverage with a written form, though most insurance experts recommend keeping it anyway.
Coverage limits vary by state and by individual choice. Some states set minimum limits that insurers must offer, while others allow lower or higher limits depending on what you select. The difference between minimum coverage and higher limits can be significant. If you carry $25,000 in UM coverage but your damages total $60,000, you would pay $35,000 out of pocket. Many insurance professionals suggest carrying limits equal to your liability limits for better protection.
Some states distinguish between uninsured motorist bodily injury coverage and uninsured motorist property damage coverage, allowing you to choose each separately. Others combine them. A few states use underinsured motorist coverage instead of uninsured motorist coverage. Underinsured motorist protection covers you when the at-fault driver has insurance but their limits are too low to cover your full damages.
Your state's insurance department website provides specific information about requirements in your area. These sites often have guides explaining minimum coverage levels and what consumers should know about UM insurance. Since requirements and laws change, checking your state's insurance commissioner's office ensures you have current information.
Practical Takeaway: Visit your state's insurance commissioner website to learn your state's specific UM requirements and recommended coverage levels. This helps you understand whether you need UM coverage and what limits would provide adequate protection based on your circumstances.
The cost of uninsured motorist insurance varies based on multiple factors. Unlike some coverage types, UM insurance typically costs less than comparable liability coverage. On average, uninsured motorist bodily injury coverage adds $10 to $30 per month to an insurance bill, though this varies significantly by location, age, driving record, and vehicle type. In high-risk areas with more uninsured drivers, premiums may be higher.

Insurance companies calculate UM premiums using several factors. Your driving record significantly impacts cost—drivers with accidents or violations pay higher premiums than those with clean records. Your age and gender also factor in because statistical data shows certain age groups have higher accident rates. The type of vehicle you drive matters because some vehicles are more expensive to repair or have higher medical cost histories. Where you live affects pricing because areas with higher accident rates and more uninsured drivers typically have higher UM premiums.
Your chosen coverage limits directly affect the cost. A $15,000 limit costs less than a $50,000 limit because the insurance company's potential financial exposure is lower with lower limits. Some people choose minimum limits to keep premiums down, while others select higher limits for more protection. The relationship is generally proportional—doubling your limit roughly doubles the cost.
Insurance companies also consider your claims history. If you've filed multiple claims previously, your UM premium may be higher than someone with no claims history. Some insurers offer discounts for bundling multiple policies, maintaining continuous coverage without lapses, completing defensive driving courses, or having safety features in your vehicle. These discounts can reduce your overall insurance costs, including UM coverage.
Shopping around for quotes from different insurers can reveal significant price differences for the same coverage. One company might charge $20 monthly for UM coverage while another charges $35 for identical limits. Getting quotes from at least three insurers helps you find competitive pricing. Many insurance companies offer online quote tools where you can compare costs without committing to purchase.
Practical Takeaway: Request quotes from at least three different insurance companies for the same UM coverage limits. Compare not just price but also customer service ratings and coverage options. Higher premiums don't always mean better coverage, and lower premiums don't always indicate poor service.
Uninsured motorist coverage works alongside other types of auto insurance but serves a different purpose than each.
