Handle uninsured underinsured and unknown drivers

By Jacob Alford

What if the other driver has no insurance or too little insurance?

UM generally addresses a responsible driver without applicable liability insurance. UIM addresses insufficient applicable liability insurance for covered damages.

Do not decide the claim solely by comparing two policy limits. The governing Texas UIM framework considers the damages and available liability proceeds, subject to the policy limit and applicable rules. A driver can be underinsured even when a simple comparison of the listed limits seems to suggest otherwise. TDI’s Stracener guidance.

What if I cannot identify the driver?

Report the incident to police promptly and give your insurer the information you have. Preserve photographs, contact evidence, witness details and video. Texas’s statutory framework includes an actual-physical-contact requirement when the owner or operator of the vehicle causing the injury or damage is unknown. Whether unusual indirect contact or a chain reaction qualifies needs fact-specific review. Do not assume every “miss-and-run” or hit-and-run event is covered. Insurance Code §1952.104.

Do not chase the fleeing vehicle or turn an uncertain observation into a definite plate identification. If new information identifies the vehicle later, preserve when and how you learned it and update the claim accurately.

Which UM or UIM coverage may protect me?

Check both bodily-injury and property-damage coverage and whether you qualify as an insured under the policy. A passenger or household member may have a policy lead even without owning the damaged car. TDI uninsured-motorist guidance.

The statutory $250 UM/UIM deductible concerns property damage. Do not automatically subtract it from an injury claim. OPIC coverage distinctions.

Ask the insurer to identify what it agrees is covered, what it disputes and what support it says is missing. Keep the responsible driver’s coverage information, settlement documents and proof of damages together. Obtain individual advice before a deadline or release forces a choice; do not abandon the inquiry merely because the first insurer had little or no coverage.

What should I check before settling with the other driver?

Before settling with the other driver, notify the UM/UIM insurer and ask about consent, notice, recovery rights and documentation under the actual policy. Obtain the response in writing. Do not assume a signed liability release leaves every UIM issue untouched or that every procedural error necessarily destroys coverage.

Why might my own UIM claim require additional legal steps?

UIM is not an automatic check for the difference between your medical bills and the other driver’s offer. The responsible driver’s liability, damages, underinsured status and policy conditions can remain disputed. Texas recognizes a declaratory-judgment route for establishing disputed UIM entitlement; not every claim requires a trial, but a contested one may require legal proceedings. Allstate v. Irwin.

The handling of UIM entitlement and separate insurer-conduct claims has its own procedural rules. Current Texas Supreme Court guidance addresses separating and pausing related claims while entitlement is determined. A low offer alone does not answer all those legal questions. In re State Farm, April 25, 2025.

How do I check whether a UM/UIM rejection actually applies to this policy and person?

Ask for any written UM/UIM rejection relied upon, including the original record and any earlier policy it concerns. Identify the signer’s status, the insurer, policy period, coverage rejected and any later written request to add coverage. The relevant issue is whether the rejection legally applies to this policy and claim, not merely whether you personally remember signing a form. Have a disputed signature, missing record or inconsistent history reviewed. For the complete policy-document request, see obtaining the policy and selection or rejection records.

Can I combine or stack coverage from more than one auto policy?

Possibly, but first establish that each policy actually covers this person and loss. “Stacking” describes combining available coverage or limits. It does not mean that every car, premium or insurance card automatically creates another payment.

Collect each complete policy, declarations and endorsements for the wreck date. Identify the named insured, the actual underwriting company, the coverage and limits, and the provisions addressing other insurance or combining limits. Similar brand names do not necessarily identify the same underwriting company.

TDI’s personal-auto checklist limits anti-stacking provisions to policies issued to the named insured by the same underwriting company. It says such language may not exclude or limit other separate, applicable policies issued by affiliated or unrelated companies. That makes the policy identities and applicability important, rather than allowing a broad “Texas never permits stacking” answer. TDI personal-auto requirements, Anti-Stacking Provisions.

The payment order, covered damages, amounts recovered or recoverable elsewhere and the particular coverage still matter. Do not add every listed limit and call the result your settlement. Finding applicable insurance covers locating and comparing policies; the earlier answers on this page cover UM/UIM entitlement and release issues.
