⚡ Key Takeaways
- An underinsured drunk driver accident lawyer in Houston pursues UIM coverage from your own policy when the at-fault driver’s limits are too low to cover your actual damages.
- Texas’s minimum liability limit is only $30,000 per person — far below the cost of serious injuries in most DUI crashes.
- UIM coverage is triggered when the drunk driver’s limits are exhausted and your damages exceed what their policy pays.
- You must typically exhaust the at-fault driver’s policy first and get written consent from your UIM insurer before settling with that driver’s insurer.
- Dram shop claims against bars can also supplement UIM coverage when multiple sources are available — they are not mutually exclusive.
- UIM insurers will attempt to minimize payouts — never accept a UIM settlement without an attorney reviewing your full damages picture.
An underinsured drunk driver accident lawyer in Houston deals with one of the most common but least understood insurance scenarios in Texas DUI crash cases: the at-fault driver has insurance, but their policy limits are too low to cover the victim’s actual damages. Texas’s minimum liability coverage of $30,000 per person is wholly inadequate for any serious injury case — and the gap between what the drunk driver’s insurer pays and what the victim is actually owed can be enormous. This guide explains how Underinsured Motorist (UIM) coverage works, when it applies, and how to maximize recovery when you’re facing an underinsured drunk driver in Houston.
What Does “Underinsured” Mean in a Houston Drunk Driving Accident Case?

A drunk driver is legally “underinsured” when their liability policy limits are insufficient to fully compensate your damages. This is not a rare situation in Houston DUI cases — it is the norm. Texas requires only $30,000 per person in bodily injury liability coverage. A victim with a serious TBI, spinal cord injury, or wrongful death claim can have damages that far exceed $30,000, $100,000, or even $500,000. When the drunk driver’s insurer pays its full policy limit and the victim is still uncompensated for a substantial portion of their losses, UIM coverage steps in to bridge the gap.

How UIM Coverage Works in a Houston Drunk Driving Case

Underinsured Motorist coverage (UIM) is purchased from your own auto insurer as part of your personal auto policy. Under Texas Insurance Code Section 1952.101, Texas insurers must offer UIM coverage to all policyholders. UIM coverage activates when: the at-fault driver has liability insurance; their policy limits are exhausted; and your proven damages exceed the amount you received from their insurer. Your UIM insurer then pays the difference between what you received from the drunk driver’s insurer and your UIM policy limit. For example, if your damages are $200,000, the drunk driver’s insurer pays its $30,000 limit, and you have $250,000 in UIM coverage, your UIM insurer would owe up to $170,000 — the gap between what you received and your proven damages.
The Critical Consent-to-Settle Requirement
One of the most important and most commonly mishandled requirements in Texas UIM claims is the consent-to-settle process. Before settling with the drunk driver’s liability insurer, you must typically obtain written consent from your own UIM insurer. If you settle with the drunk driver’s insurer without notifying and obtaining consent from your UIM carrier, you may inadvertently waive your UIM claim. Your underinsured drunk driver accident lawyer manages this process — notifying your UIM insurer of the pending settlement, securing written consent, and ensuring you do not accidentally forfeit the UIM claim while resolving the primary liability claim. This procedural requirement has destroyed otherwise valid UIM claims for victims who tried to handle it themselves.
UIM Coverage and Dram Shop Claims: Using Both Simultaneously
UIM coverage and dram shop liability claims against bars are not mutually exclusive. If the underinsured drunk driver was drinking at a bar before the crash, your attorney can simultaneously pursue the drunk driver’s liability policy, a dram shop claim against the bar, and your own UIM coverage — each as a separate, independent source of compensation. The total recovery is calculated across all sources. Dram shop defendants often carry $1 million or more in commercial liability insurance, making the dram shop claim frequently the most significant source of compensation in cases where the drunk driver’s policy is inadequate.

How UIM Insurers Handle Houston Drunk Driving Claims
Despite the fact that UIM coverage is purchased by you to protect yourself, your own UIM insurer operates as an adverse party when it comes to paying claims. They will evaluate your medical records, dispute the causation and severity of your injuries, challenge your future damages projections, and offer settlements that are below the true value of your claim. They have every financial incentive to minimize the payout. An underinsured drunk driver accident lawyer in Houston represents your interests against your own insurer — presenting the full damages picture, including expert testimony from treating physicians, life-care planners, and vocational experts, and negotiating or litigating to achieve the full recovery your UIM policy supports.
What to Do When You Suspect the Drunk Driver Is Underinsured
Seek same-day medical treatment and begin documenting your injuries. Obtain the at-fault driver’s insurance information from the police report and have your attorney verify their policy limits through formal legal channels. Notify your own insurer of the potential UIM claim without giving a recorded statement. Retain an underinsured drunk driver accident lawyer in Houston before accepting any settlement from the at-fault driver’s insurer — because the consent-to-settle requirement means your attorney must be involved before that payment is accepted.

When does UIM coverage apply in a Houston drunk driving case?
UIM coverage applies when the drunk driver’s liability limits are exhausted and your damages exceed what you received from their insurer. Your UIM carrier pays the gap up to your UIM policy limit. Texas minimum liability coverage of $30,000 per person is frequently exhausted in any serious injury case, triggering UIM coverage for the balance.
What happens if I settle with the drunk driver’s insurer before notifying my UIM carrier?
You may inadvertently waive your UIM claim. Texas law requires obtaining written consent from your UIM insurer before settling with the at-fault driver’s liability insurer. This procedural step is one of the most commonly mishandled aspects of underinsured drunk driver claims and is a primary reason to retain an attorney before accepting any settlement offer.
