Quick Answer: Uninsured motorist coverage is an add-on to your auto insurance policy that pays when an at-fault driver has no insurance or flees the scene. It covers your medical bills, lost wages, and vehicle repairs through two parts: bodily injury (UMBI) and property damage (UMPD). In Texas, insurers include it automatically unless you reject it in writing.

What Is Uninsured Motorist Coverage and What Does It Cover? 

Picture this: you’re stopped on Beltway 8 in Houston when a pickup rear-ends you. The driver apologizes, then admits he has no insurance. Your neck aches, your bumper is crushed, and nobody on the other side has a policy to pay for any of it. 

That’s the moment uninsured motorist coverage (UM) earns its keep. The Texas Department of Motor Vehicles estimates that about 11.87 percent of Texas drivers are uninsured, roughly one in eight. When our agents sit down with drivers at any of our Houston and Dallas-area offices, this is a coverage many drivers are surprised to find missing. 

What Is Uninsured Motorist Coverage? 

Uninsured motorist coverage is the part of your own policy that protects you from other people’s missing insurance. Our insurance glossary defines it as the portion of an auto policy that protects you from uninsured and hit-and-run drivers. In plain words: your insurer steps in and pays what the at-fault driver should have paid. 

It applies in three situations. The other driver has no liability insurance. The other driver leaves the scene and can’t be identified. Or the other driver’s policy is too small, which brings in underinsured coverage (more on that below). 

Here’s the thing most people miss: UM protects you, not the other driver. It also follows you, not just your car, so it can help when you’re a passenger or walking. Riders benefit too, since a motorcycle crash with an uninsured driver is rarely minor. That’s why it’s worth asking about on a motorcycle insurance policy too. 

What Does Uninsured Motorist Coverage Cover? 

UM comes in two parts, and each one answers a different question: who pays for you, and who pays for your car? They show up as separate lines on your declarations page, and you can carry one without the other. Not sure what yours says? Ask an agent to read it with you. 

1. Uninsured Motorist Bodily Injury Coverage (UMBI) 

UMBI pays for injuries you and your passengers suffer. Think of it as the mirror image of the bodily injury liability you carry for others, which we break down in what the main purpose of auto insurance is. It typically helps with: 

• Emergency room visits, surgery, and hospital stays

• Follow-up care like physical therapy and prescriptions 

• Lost wages while you recover 

• Pain and suffering 

Texas also builds personal injury protection (PIP) into policies unless you reject it. PIP pays medical bills no matter who caused the crash, with a $2,500 minimum, so it works as a first layer. UMBI covers the larger losses PIP can’t reach. 

2. Uninsured Motorist Property Damage Coverage (UMPD) 

UMPD pays to repair or replace your vehicle when an uninsured driver damages it. Texas sets the UMPD deductible at $250, which is usually far lower than a collision deductible. If you want to see how that math works, our guide to what a deductible in car insurance means lays it out simply. 

Say an uninsured driver causes $6,000 in damage to your car. With UMPD, you pay the $250 deductible and your insurer handles the rest, up to your limit. Without it, you either run the claim through collision at a higher deductible or chase the other driver for money he may not have.

UM won’t pay for damage you cause, and it doesn’t replace a work policy. If you drive for business, a commercial auto insurance policy is built for that exposure.

What Is the Difference Between Uninsured and Underinsured Motorist Coverage? 

Uninsured means the at-fault driver has nothing. Underinsured means they have something, but not enough. Texas combines both into one coverage, usually called UM/UIM, so you rarely buy them separately.

The second row matters more than it looks. Texas’s minimum liability limits are 30/60/25, meaning $30,000 per injured person, $60,000 per accident, and $25,000 for property damage. A single night in intensive care can pass $30,000 quickly, which is why we wrote about whether Texas minimum car insurance is enough. 

Hit-and-run claims deserve a caution. Insurers often expect a police report, and many require physical contact between the vehicles. Report the crash quickly and keep your photos. 

Is Uninsured Motorist Coverage Required in Texas? 

No, you aren’t required to buy it. But your insurer is required to include it. Under Texas Insurance Code Chapter 1952, UM/UIM must be part of your auto liability policy unless a named insured rejects it in writing. So the coverage is on your policy by default, unless someone signed it away. 

That signature often happens quietly at purchase, when someone is trying to hit a monthly number. And it can stick. If a named insured rejected UM years ago, the insurer generally doesn’t have to add it back at renewal unless you ask in writing. Our deeper walkthrough on uninsured motorist coverage in Texas shows how to check your own policy. 

Not sure whether you rejected it? Stop by our Baytown office with your declarations page and an agent will go through it with you. Crossing the border is another gap: most U.S. policies, UM included, stop at the Mexico line, so plan on separate Mexico auto insurance. 

How Much Uninsured Motorist Coverage Do You Need? 

Texas lets you buy UM up to your own liability limits. Our view: if you can afford to match them, do. Why protect other people at $100,000 and yourself at $30,000? 

Several things move the number: your health insurance deductible, your income, who rides with you, and how much a long recovery would cost. In most cases, the premium difference between minimum and higher UM limits is small compared with the protection. You can see real pricing when you request an auto insurance quote. 

If your assets are larger, ask about an umbrella policy on top. Trade-offs exist, though. Your premium is higher with more coverage, and your mileage will vary by carrier and ZIP code. Our piece on ways to lower your car insurance shows how to keep the cost down. 

FAQs About Uninsured Motorist Coverage 

Does uninsured motorist coverage pay my medical bills? 

Yes. UMBI pays reasonable medical bills and lost wages after a crash with an uninsured driver. PIP may pay first, and UMBI picks up the larger losses. 

Does it pay for car repairs? 

Yes, through UMPD, usually with a $250 deductible. If you don’t carry UMPD, you’d rely on collision, which has a higher deductible. 

Does uninsured motorist coverage apply if I’m a passenger? 

Generally, yes. UM can cover you in someone else’s car, and it covers passengers in yours. Check your policy wording. 

Will a UM claim raise my rates? 

Not-at-fault claims are generally treated more gently than at-fault ones, but practices vary by insurer. Ask your agent before you file. 

What if the other driver has insurance, but not enough? 

Underinsured motorist coverage can cover the gap, up to your UIM limit. In Texas it’s usually bundled with UM. 

Can I add UM coverage to my policy later?

Yes. Ask your insurer to add it in writing. Coverage begins when the change takes effect, so it won’t help with a crash that already happened. 

Conclusion: Understand Your Uninsured Motorist Coverage Options 

You can’t control who’s driving next to you on I-10. You can control what is written on your own policy. Pull out your declarations page today and look for two lines: UMBI and UMPD. If either is missing, ask why.
