Underinsured Motorist Coverage in Texas

Underinsured motorist coverage addresses a shortfall, not the total absence of insurance. The at-fault driver has collectible liability insurance, but the available limit is too small to cover the injured insured's legally recoverable damages. In Texas, the policy's UIM limit and the other driver's liability coverage are compared under the statutory definition. If the vehicle qualifies as underinsured, UIM can provide an additional source of recovery, subject to the insured's damages, policy limit, offsets, and contract terms.

The phrase 'underinsured' can sound like an everyday judgment about a small policy. Texas law uses a more precise test: an insured vehicle is underinsured when collectible liability limits were originally lower than, or have been reduced by payments for claims from the same accident to, an amount below the UIM limit stated in the insured's policy. A driver can carry the state's minimum liability coverage and still be underinsured relative to a claimant's UIM limit and damages.

How UIM differs from liability insurance

The at-fault driver's liability insurance is third-party coverage. It pays covered damages the driver legally owes to others, subject to that driver's limits and policy. UIM is first-party coverage in the injured person's own policy. The injured person still must establish the other driver's legal responsibility and the value of damages. UIM does not transform a disputed accident into an automatic payment, and the tort claim against the driver remains relevant.

A simple comparison: a driver carries a low liability limit; a collision injures someone whose damages are larger; the injured person has a UIM limit above the other driver's collectible limit. The liability carrier may tender or pay its available limit, and the injured person may then seek additional covered damages from the UIM insurer. The UIM carrier evaluates fault, damages, insured status, limits, and any policy conditions. Payment cannot exceed the insured's covered damages or the applicable contractual ceiling.

A worked UIM example

Assume a claimant has $90,000 in legally recoverable covered damages, the at-fault driver has $30,000 in collectible liability coverage, and the claimant's UIM limit is $100,000. For a simplified exam illustration, the UIM layer is not a fresh $100,000 on top of the driver's payment. Texas Insurance Code says UIM payment is reduced by what was recovered or is recoverable from the underinsured vehicle's insurer. If the full $30,000 is recoverable and paid, up to $60,000 of additional covered damages may remain within the UIM ceiling, before applying other policy terms.

This is a teaching example, not a claim offer formula for every policy. The facts can change if multiple injured people compete for a per-accident limit, payments reduce the other driver's available limits, liability is disputed, damages are not covered, or the settlement is less than an amount the UIM carrier considers recoverable. 'Recoverable' matters: accepting less than the available liability limit may affect the calculation, and consent or notice provisions may apply. Review the policy and obtain appropriate claim guidance before resolving the tort claim.

Do not simply subtract the tortfeasor's per-person limit from the UIM limit in every case and call the result payable. The UIM insurer does not automatically owe the difference between limits. The insured must show covered damages exceed amounts available, establish fault, comply with conditions, and account for other claimants and policy terms. The right computation depends on what is legally recoverable, not just numbers printed on two declarations pages.

Texas offer and written rejection

Texas Insurance Code Chapter 1952 requires an insurer writing an auto liability policy to provide UM/UIM coverage in or supplemental to the policy. An insured named in the policy may reject it in writing. If rejection occurred under that policy or certain earlier policies issued by the same or an affiliated insurer, the insurer may not have to add coverage at renewal or reinstatement unless the named insured requests it in writing. In plain terms, Texas's default is an offer, but an earlier written rejection can persist.

The policy declarations are the practical verification point. Do not infer UIM coverage from the existence of bodily injury liability insurance, from a prior vehicle's coverage, or from a verbal recollection. Ask whether UIM is selected, what the limit is, whether it is combined with UM, and which autos or insureds qualify. Retain the written rejection or election. The exam may distinguish the insurer's offer duty from the policyholder's eventual selection.

Texas law sets a ceiling: UIM bodily-injury limits cannot exceed the insured's bodily-injury liability limits. The law also provides an offset for amounts recovered or recoverable from the at-fault insurer. These rules are not the same as a guaranteed minimum benefit. The policy may have less than the insured's total damages, and the UIM limit is the most the policy will pay subject to its aggregation rules.

UIM bodily injury and property damage

UIM can address bodily-injury damages and property damage, but the claim categories should be kept distinct. Injury claims may include medical expenses and other legally recoverable damages under applicable law and policy wording. Property-damage claims may address a covered auto or other property. Texas Insurance Code allows an insured carrying collision and UM/UIM property-damage coverage to choose a path for physical damage to the car. Collision and UIM can have different deductibles and proof requirements.

If the vehicle is damaged, collision may be the more straightforward first-party route because it does not depend on proving that the other vehicle meets the UIM definition. UIM property damage may offer a different deductible or benefits. TDI's auto guide says a collision or UM/UIM claim can help cover the difference when the other driver's limits are not enough, but an insured generally must pay a deductible on a claim under their own policy. Check the actual declaration amounts.

UIM is not gap insurance. Gap coverage responds to the difference between a vehicle loan balance and the vehicle's value after a total loss, if purchased and applicable. UIM responds to legally recoverable damages caused by an underinsured motorist. The policy object and calculation differ. The same crash can create both a vehicle loan shortfall and a bodily-injury UIM claim, but one coverage does not substitute for the other.

Who may qualify and what evidence matters?

The insured-person definition controls whether the claimant can use the policy. A named insured, resident relative, passenger, or permissive user may be treated differently depending on the form and relationship to the covered auto. A policy can define insured persons for UM/UIM separately from collision or medical payments. Review the definitions, declarations, endorsements, and any named-driver exclusions.

A UIM file commonly needs the crash report, photographs, witness details, medical records and bills, proof of wage loss where relevant, and the other driver's insurance and payment information. The insured must show liability and damages. The UIM carrier may investigate separately even if the other insurer has paid its limit. Keep records of settlement offers and payment amounts because Texas law's recoverable-offset rule makes them material.

Scenario: Luis is injured when an at-fault driver turns across his lane. The other driver has liability insurance, but the available limit is smaller than Luis's alleged covered damages. Luis should not treat the small liability limit as proof that the UIM carrier must pay immediately. He must document his injuries and expenses, establish fault and legal entitlement, confirm UIM is in force, notify his insurer, and account for any amounts recovered or recoverable from the other driver.

Exam traps and practical checklist

• Uninsured and underinsured are distinct: no applicable insurance versus collectible insurance that is inadequate relative to the UIM limit.
• A low limit alone does not prove UIM is payable; legal entitlement and damages must be established.
• UIM is not automatically stacked on top of the at-fault driver's liability payment; Texas law offsets recovered or recoverable amounts.
• A prior written rejection may affect renewal or reinstatement coverage.
• Collision and UIM property-damage are separate claim routes, each with terms and deductibles.
• The insured's policy limit and the other driver's available limits are not the only relevant numbers; damages and competing claims matter.

My view: the hardest UIM exam questions are arithmetic traps disguised as vocabulary questions. Before calculating, state who is suing whom and what policy is responding. Then write the other driver's available payment, covered damages, and the insured's UIM limit on separate lines. That keeps the subtraction rule from turning into an invented extra limit.

1. Confirm the UIM coverage selection, limit, covered auto, and insured status.
2. Check the at-fault vehicle's collectible limits and whether prior payments reduced them.
3. Establish legal liability and covered damages.
4. Apply Texas's offset for amounts recovered or recoverable from that insurer.
5. Apply UIM limits, aggregation rules, exclusions, and policy conditions.
6. Keep bodily-injury and property-damage analysis separate, including any collision option.

Why notice and settlement sequence matter

A UIM claim often develops alongside a liability claim against the driver who caused the accident. The other driver's insurer may investigate fault, value injuries, and offer its available limit. Your UIM insurer may need the same records and may have policy rights concerning notice, cooperation, or consent before a settlement releases the driver. Do not assume that a liability payment closes the UIM file or that you can accept any amount without consequences. Read the policy and coordinate communications before signing a release.

Texas's offset refers to what is recovered or recoverable from the underinsured motorist's insurer. That makes the available liability limit important even if the claimant would prefer to move directly to their own carrier. If a settlement is below an available limit, the reason for the reduction and any required consent can become relevant. Preserve the written offer, payment confirmation, release, and explanation of how the liability limit was allocated among injured people.

Multiple claimants create a second calculation issue. A per-person limit can be available to one claimant, while the per-accident limit caps the total payment to everyone. If several people are hurt, the at-fault insurer's limit may be exhausted through allocation, reducing what is actually collectible for one person's claim. Texas's underinsured definition accounts for limits that have been reduced by payments from claims arising out of the same accident. A candidate should read all the figures in the problem, not only the per-person amount.

Do not delay medical evaluation or the ordinary claim notice while you wait to see whether a case will become underinsured. The insurer needs a reliable record of the event and injuries. Keep bills, treatment notes, wage records, repair estimates, and communications organized. The policy may impose notice and cooperation conditions, and the applicable deadline cannot be inferred from a generic online summary.
