Uninsured and Underinsured Motorist Claims in Texas: A Houston Guide
Insurance Claims 9 min read
You did everything right. You carried insurance, you obeyed the law, and someone still ran a light and wrecked your car. Then you learn the other driver has no policy at all, or carries the Texas minimum of $30,000 per person, which barely covers one night in a Houston trauma center. Roughly one in five Texas drivers is uninsured, and many more are badly underinsured. In those cases your own uninsured and underinsured motorist coverage becomes the primary source of recovery, and the process is nothing like a normal claim: the company you have paid premiums to for years is now the party arguing your injuries are not worth what you say.
How UM and UIM Coverage Works in Texas
Uninsured motorist coverage applies when the at-fault driver has no liability insurance, when their insurer denies coverage, or in most policies when an unidentified hit and run driver causes the crash. Underinsured motorist coverage applies when the at-fault driver has insurance but not enough to cover your damages. Texas insurers must offer both, and the coverage is only excluded if you rejected it in writing, which means many drivers have it without realizing it.
Texas UIM coverage is what lawyers call excess, not gap. If the at-fault driver carries $30,000 and your damages are $100,000 with $50,000 in UIM coverage, you collect the $30,000 liability limit and then pursue your UIM policy on top of it, up to its limits. Coverage typically extends to you, resident relatives, and passengers in your vehicle, and often protects you as a pedestrian or a cyclist as well.
Many policies also include a small amount of personal injury protection, or PIP, which pays medical bills and a portion of lost wages regardless of fault. PIP is automatic in Texas unless rejected in writing and should be opened immediately after a crash.
The Consent Trap That Voids UIM Claims
This is the single most expensive mistake injured Texans make. Nearly every auto policy contains a subrogation clause requiring you to obtain your insurer's written consent before settling with the at-fault driver. Accept the other driver's policy limits without that consent and your carrier can deny your UIM claim outright, no matter how badly you were hurt.
The correct sequence is to notify your own carrier of the crash immediately, send the liability settlement offer for written approval, wait for the consent letter, and only then sign a release. That step costs nothing and takes days. Skipping it can cost the entire value of a claim.
Protect your UIM claim from day one
- Report the crash to your own insurer even though it was not your fault
- Open your PIP benefits right away to keep medical bills current
- Never sign a liability release before your carrier consents in writing
- Request certified copies of every applicable policy declaration page
- Document every household vehicle policy that might stack
- Keep a written log of every adjuster call and what was promised
Why Your Own Insurer Can Legally Stall
Texas UIM law is unusual and it explains a lot of the frustration people feel. Under the Texas Supreme Court's decision in Brainard v. Trinity Universal Insurance, a UIM insurer owes nothing until the insured establishes both the other driver's liability and the amount of damages, usually by judgment. Sending medical bills and a demand letter does not, by itself, trigger a duty to pay.
The practical result is that a UIM carrier can decline a reasonable demand without the immediate bad-faith exposure a liability insurer would face. Getting paid often requires filing suit against your own carrier, and increasingly the process runs through the informal settlement conference and trial procedures added by Texas Insurance Code Chapter 1952 for UIM disputes.
None of this means UIM claims cannot be settled. It means they settle when the file is built like a case that is going to court: complete records, a clear liability picture, treating-physician causation opinions, and documented wage loss. Adjusters value what is proven, not what is claimed.
Finding Every Policy That Applies
The recovery in these cases is usually built from several sources rather than one. The at-fault driver's liability limits come first. Your own UM or UIM policy follows. A resident relative's policy in the same household may apply to you. If you were working at the time, an employer's non-owned auto or commercial UIM coverage can apply. If a rideshare app was active, the platform's contingent coverage may be triggered.
Umbrella policies are the most overlooked layer. Many Houston households carry a personal umbrella that includes excess UM/UIM coverage and never think to mention it after a crash. Identifying the full coverage stack early determines the realistic ceiling of your claim and shapes how the case is worked.
Coverage sources worth checking after a Houston crash
- At-fault driver's liability policy and any employer policy
- Your own UM/UIM coverage on every vehicle you own
- Resident relative policies in the same household
- Personal umbrella policies with excess UM/UIM endorsements
- PIP or MedPay for immediate medical bills and wage loss
- Rideshare or delivery platform contingent coverage
Frequently Asked Questions
Will my rates go up if I file a UM or UIM claim?
Texas insurers generally cannot surcharge you for a claim in which you were not at fault. You paid premiums specifically for this coverage, and using it after another driver's negligence is exactly its purpose.
What if I do not know whether I have UM or UIM coverage?
Texas insurers must include it unless you rejected it in writing, so many drivers have coverage they forgot about. Request your full policy and declarations page; if the carrier cannot produce a signed written rejection, the coverage generally applies.
Can I make a UIM claim if the hit and run driver was never identified?
Usually yes under uninsured motorist coverage, though most policies require prompt reporting to law enforcement and, in some unidentified-vehicle situations, corroborating evidence such as physical contact or an independent witness.
How long do I have to bring a UIM claim in Texas?
The underlying injury claim generally carries a two-year deadline, but the contract claim against your own insurer has its own timeline and policy notice conditions. Because the deadlines differ, treat the two-year mark as the outside limit and start early.
