Uninsured and Underinsured Motorist Coverage in Texas, Explained

If the other driver has no insurance or not enough, this coverage on your own policy may be what actually pays your claim.

If a driver in New Braunfels hits you and has no insurance, or barely enough to cover a fender bender, you might assume you're out of luck. You're not. Texas allows drivers to carry uninsured and underinsured motorist coverage, often called UM/UIM, specifically for this situation.

This coverage sits on your own auto policy, not the other driver's. It steps in when the at-fault driver can't pay for your medical bills, lost income, and other losses because they either have no insurance at all or their policy limits run out before your costs do. Understanding how it works before you need it can save you real stress after a wreck.

What UM/UIM Coverage Actually Does

Uninsured motorist coverage applies when the driver who caused your crash has no liability insurance whatsoever. Underinsured motorist coverage applies when they do have insurance, but their policy limits are too low to cover what you actually lost. In both situations, you file a claim against your own policy instead of theirs.

This might feel backwards. You didn't cause the wreck, so why are you dealing with your own insurer? The answer is practical: your insurer already has your premium, already knows your policy terms, and is the one contractually obligated to pay when the other side can't. It's a financial safety net you paid for, built to catch exactly this kind of gap.

Why This Matters More Than People Think

Texas has a large number of drivers on the road without insurance, and even drivers who carry coverage often choose the state's minimum limits. Minimum liability limits can be used up quickly by a single hospital visit, let alone surgery, physical therapy, or missed work. When that happens, the at-fault driver's insurance simply stops paying, and any remaining costs are left unaddressed unless you have another source.

This is where a lot of injured people get blindsided. They assume that because the other driver was clearly at fault, their bills will be covered. But liability and payment are two different things. A driver can be 100 percent at fault and still not have the financial backing to cover what they caused. UM/UIM coverage is the bridge between fault and actual payment.

How a UM/UIM Claim Works in Practice

When you open a UM/UIM claim, your insurer investigates the crash much like the at-fault driver's insurer would. They look at the police report, medical records, and evidence about how the wreck happened. You'll typically need to show that the other driver was at fault and that your damages exceed what their insurance is able to pay.

One important detail: if the at-fault driver does have some insurance, you generally need to deal with their liability coverage first before turning to your underinsured motorist coverage for the remaining gap. Your policy usually requires notice of this process, and there are contractual steps involved, so it helps to loop in your insurer early rather than after everything is already settled.

Because you're technically filing against your own insurance company, it's easy to assume the process will feel friendly and cooperative. In reality, your insurer still has a financial interest in paying out as little as possible on a UM/UIM claim. Treat it with the same care and documentation you'd use with any other insurance claim.

Is This Coverage Required, and How Much Should You Carry

Texas does not force every driver to carry UM/UIM coverage, but insurers are generally required to offer it, and many drivers carry it without realizing exactly what it does. If you're unsure whether you have it, or how much, check your policy declarations page or call your agent and ask directly.

Coverage limits vary a lot from one driver to another. Some people carry the same amount as their liability coverage; others carry less or decline it in writing. Since you can't control what insurance the other driver has, the only real lever you control is your own limit, which is worth reviewing periodically, especially after a life change like a new car, a new driver in the house, or a longer commute.

What To Do If You Think You'll Need This Coverage

If you've been in a crash and learn the other driver has no insurance, or their insurer says the limits won't cover your medical bills, don't wait to act. Check your own policy for UM/UIM coverage right away, and notify your insurer that you may need to make a claim under it. Delaying can create complications, since insurance contracts often have their own notice requirements separate from any court deadlines.

Keep careful records of your medical treatment, missed work, and any communication with either insurance company. Because a UM/UIM claim still requires proving the other driver was at fault and how much you were harmed, the same kind of documentation that matters in any injury claim matters here too.
