Hit by an Uninsured Driver? What to Know

What "Underinsured" Actually Means

“An underinsured driver has insurance, but their liability limits are not high enough to cover the full cost of the injuries or damages they cause. An uninsured driver, on the other hand, is someone who does not carry auto liability insurance whatsoever, despite state requirements to do so,” explains Janet Ruiz, director of Strategic Communication for the Insurance Information Institute.^[2]

It’s easy to assume that having car insurance means you’re fully covered. But that’s not correct. State minimums are often far below what a serious accident actually costs, and even if the other at-fault driver technically has an auto policy, you can still be financially vulnerable.

Case in point: Let’s say the at-fault driver carries minimum liability coverage, which in your state is $25,000. But if your medical bills and vehicle damage total $55,000, you’re on the hook for the remaining $30,000.

More Drivers Than You Think Aren't Covered

The percentage of motorists lacking proper coverage is a lot higher than many people think, and the numbers have been trending in the wrong direction as premiums continue to rise. Per the Insurance Information Institute, the country’s rate of uninsured drivers has been climbing in recent years: from 11.6% in 2019 up to 15.4% in 2023, with the largest upward trends observed in the District of Columbia, New Jersey, and Missouri. Mississippi has the highest percentage of uninsured drivers in the country at 28.2%, followed by New Mexico (24.1%), the District of Columbia (23.1%), Michigan (22.3%), and Tennessee (21.3%). ^[3]

“This is actually a very common problem where I practice in Florida, where roughly 20% of drivers are uninsured,” says Stacy Kemp Ferrari, a personal injury attorney.^[4]

Making the problem worse, mandatory liability limits in many states remain low. That means even drivers who follow the law often carry inadequate coverage to handle modern medical or repair bills.

As escalating premiums cause more policyholders to maintain bare-minimum protection or drop coverage completely, the rest of us have to pick up the slack in the form of greater financial risks and higher costs to safeguard ourselves against the mounting number of under-protected drivers.

What Your Own Policy Can Do

To better defend yourself against either type of at-fault driver, your car insurance policy should include UM (uninsured motorist) and UIM (underinsured motorist) coverage. The former helps pay for injuries and, in some states, property damage if you are hit by a driver with no insurance, and the latter helps cover your losses when the at-fault driver’s insurance limits are exhausted before all damages have been paid. 

“Most drivers don’t carry enough UM/UIM coverage because they just match it to their liability limits – often the state minimum – without thinking about what accidents actually cost today,” says Beth Swanson, insurance analyst with The Zebra. “Medical costs from crashes have gone up a lot in the last few years, but plenty of people’s coverage hasn’t.” 

Carriers are required to include UM (and frequently UIM) coverage in about 20 states and Washington, D.C., in standard liability policies. Other states, like California, Florida, Pennsylvania, and Texas, mandate that insurers automatically include UM/UIM coverage in initial quotes, although policyholders can opt out via a formal written waiver. In other states, such as Ohio, UM and UIM coverages are optional add-ons that drivers can proactively request.

Look closely at your policy, and it might appear a bit confusing. UM and UIM are often bundled into a single coverage line on a policy, although some states allow you to purchase them separately or require different limits for each. You’ll also sometimes see UIMBI/UMBI and UIMPD/UMPD listed on your policy; the “BI” stands for bodily injury, which covers your medical bills and lost wages if you are hit and injured by a driver lacking enough or any insurance; and “PD” stands for property damage, which covers repairs to your vehicle or personal property damaged by an uninsured or underinsured motorist.

How to Make Sure You're Protected Before It Happens

The key takeaway here is that it’s risky to assume you’ll be fully covered if you suffer personal injury or damage to your car or personal property that you didn’t cause.

“To best protect yourself now, before an accident with an uninsured or underinsured motorist, you should review your policy limits and make sure you have adequate UM and UIM coverage,” suggests personal injury attorney John Malm.^[5]

Ferrari recommends beefing up your UM/UIM coverage to at least 100/300/100 (meaning up to $100,000 for injuries per person, $300,000 total for injuries per accident, and $100,000 for property damage). Although this could raise your rate, “the peace of mind would be worth it,” she says.

As always, it pays to shop around among different carriers and get rate quotes for policies that include appropriate UM/UIM coverage.

Lastly, keep in mind that you can sue an uninsured/underinsured driver for damages following an accident, “but they may be able to discharge any judgment against them in bankruptcy,” Malm notes.
