Uninsured & Underinsured Motorist Coverage (UM/UIM) in Texas

Uninsured & Underinsured Motorist Coverage (UM/UIM) in Texas

On a Friday evening in 2023, a family in San Antonio left a high-school football game and was T-boned by a pickup that ran a red light. The at-fault driver had no insurance—a violation punishable by fine but which left the victims facing substantial medical bills, lost wages, and a totaled minivan. Had they not carried uninsured-motorist coverage on their own policy, recovery would have meant years in litigation against a defendant with no assets. Their UM/UIM carrier resolved the claim.

> Note: The scenario above is illustrative. While it reflects common fact patterns in Texas UM/UIM claims, it is presented to demonstrate how coverage works, not as a verified case result.

Texas law mandates that every auto insurer offer UM/UIM protection when you buy or renew a policy, yet it does not force you to accept it. Declining coverage requires a written signature—a formality that many drivers skip through without reading. The result: thousands of Texans drive with state-minimum liability limits and zero UM/UIM cushion, a gamble that turns catastrophic when the other driver is broke, uninsured, or carries only the bare-bones $30,000 bodily-injury limit.

What UM/UIM Coverage Actually Does

Uninsured-motorist (UM) and underinsured-motorist (UIM) endorsements are two sides of one coin. UM kicks in when the at-fault driver has no valid liability insurance at all. UIM applies when the other driver's policy limit is insufficient to cover your damages—for instance, when your medical bills and lost wages bump against their $30,000 per-person cap.

Both coverages pay for:

• Medical expenses: emergency-room visits, surgery, rehabilitation, prescription drugs, mental-health counseling.
• Lost income: past wages you could not earn while recovering, plus future earning capacity if permanent impairment prevents you from returning to your former job.
• Pain and suffering: non-economic damages such as physical pain, emotional distress, loss of enjoyment of life, scarring, and disfigurement.
• Property damage: in some states UM/UIM includes vehicle repair; in Texas, uninsured-motorist property damage (UMPD) is a separate optional coverage, and many carriers fold it into collision instead.

Texas Insurance Code § 1952.101 requires every insurer to offer UM/UIM in limits equal to your liability limits unless you decline in writing. That means if you carry $100,000 per person / $300,000 per accident in bodily-injury liability, you must be offered at least $100,000/$300,000 in UM/UIM. You can buy higher UM/UIM limits—say, $250,000/$500,000—if your carrier writes them, and the incremental premium is often modest.

Why Many Texas Drivers Go Bare

Many Texas motorists drive without liability insurance, despite state law requiring it. Three factors explain the gap:

1. Economic pressure: state-minimum liability ($30,000 per person, $60,000 per accident, $25,000 property damage under Texas Transportation Code § 601.072) can be costly, particularly in high-risk rating areas; low-income drivers sometimes let policies lapse.
2. Weak enforcement: Texas law suspends the driver's license and registration of uninsured motorists, but enforcement is episodic. Many drivers gamble that they will not be stopped.
3. Judgment-proof defendants: even when an uninsured driver is sued and loses, collecting a judgment from someone with negligible assets is nearly impossible. Garnishment laws protect a portion of wages, homestead exemptions shield primary residences, and bankruptcy can discharge tort judgments.

The upshot: victims of uninsured drivers face a Hobson's choice—spend years chasing a phantom defendant or absorb the loss themselves. UM coverage converts that lose-lose into a straightforward first-party insurance claim.

The Texas UM/UIM Statute: Offer, Rejection, and Stacking

Mandatory Offer and Written Rejection

Texas Insurance Code § 1952.101 says insurers must offer UM/UIM at limits equal to the bodily-injury liability limits you purchase. If you choose lower UM/UIM limits or reject the coverage altogether, you must sign a written selection or rejection form. Many drivers sign these forms at the agent's office or click "I agree" online without reading the consequences.

Once you reject UM/UIM in writing, the insurer has no duty to provide it. Reinstatement requires affirmatively adding the coverage at renewal, which often comes with a modest rate increase.

Stacking vs. Non-Stacking Policies

Stacking allows you to combine UM/UIM limits from multiple vehicles on the same policy—or even across separate policies—when a single accident causes injury. For example, if you insure three cars, each with $100,000 in UM coverage, a stacking endorsement might let you access $300,000 total.

Texas law permits both intra-policy stacking (combining limits within one policy covering multiple vehicles) and inter-policy stacking (combining limits across separate policies you own), unless your policy contains an anti-stacking clause. Most Texas insurers include anti-stacking language, limiting recovery to the per-person limit on the vehicle you occupied at the time of the crash.

Courts have upheld anti-stacking clauses as long as the policy discloses them clearly. If you want stacking, ask your agent explicitly; some carriers offer it as a rider for an additional premium.

UM/UIM and Med-Pay Coordination

Medical-payments coverage (Med-Pay) and personal-injury-protection coverage (PIP) are first-party no-fault coverages that pay medical bills and, in the case of PIP, lost wages regardless of who caused the crash. Texas is not a no-fault state, so PIP is optional; Med-Pay is more common.

When both Med-Pay and UM/UIM apply, Med-Pay typically pays first because it requires no proof of fault. Your UM/UIM carrier may then reduce its payout by the amount Med-Pay advanced—a practice called setoff—though the policy's exact coordination-of-benefits clause controls. Reading the endorsement language is essential; some policies credit Med-Pay payments against your UM/UIM recovery, others do not.

Underinsured-Motorist Claims: The Trigger and the Math

UIM coverage becomes relevant only after the at-fault driver's liability policy pays its full limit and damages still exceed that amount. Suppose you sustain $150,000 in medical bills, $30,000 in lost wages, and $70,000 in pain and suffering—$250,000 total. The other driver carries $30,000 per person in liability. Once that $30,000 is tendered, you have a $220,000 gap.

If your UIM limit is $100,000 per person, the maximum additional recovery from your own carrier is typically $100,000 minus the $30,000 already paid by the tortfeasor's insurer, yielding $70,000. Some policies use a difference-in-limits formula: UIM pays the difference between the other driver's limit ($30,000) and your UIM limit ($100,000), so $70,000. Other policies use a limits-minus-recovery approach: UIM pays your total damages ($250,000) minus the tortfeasor payment ($30,000), capped at your UIM limit ($100,000), also yielding $70,000 in this example but producing different results when damages are lower.

Texas case law and policy-specific endorsements dictate which formula applies. Many carriers use limits-minus-recovery. Always review the declarations page and the UM/UIM endorsement.

The Claims Process: Notice, Cooperation, and Arbitration

Prompt Notice

Most UM/UIM policies require you to notify the insurer "as soon as practicable" after a crash involving an uninsured or underinsured driver. While Texas law does not impose a statutory notice deadline for first-party UM/UIM claims (unlike the strict pre-suit notice rules for government defendants under the Texas Tort Claims Act), delaying notice by months can trigger a coverage defense if the insurer proves prejudice.

Best practice: report the crash to your own carrier within days, even if you are also pursuing the at-fault driver's liability policy.

Investigation and Cooperation

Your UM/UIM carrier has the right to investigate fault, verify the other driver's insurance status, and examine your medical records. You have a contractual duty to cooperate—submitting to examinations under oath, providing authorizations for medical records, and appearing for independent medical examinations (IMEs) if requested.

Failure to cooperate can void coverage, though Texas courts require the insurer to prove that non-cooperation was material and prejudicial.

Arbitration Clauses

Many UM/UIM endorsements contain binding-arbitration clauses. When you and your insurer disagree on the value of your claim—you say your injuries are worth $200,000, they offer $50,000—the dispute goes to an arbitrator rather than a jury. Texas Insurance Code § 1952.101 permits arbitration clauses in UM/UIM policies, and courts generally enforce them.

Arbitration can be faster and cheaper than litigation, but it also forfeits your right to a jury trial and limits appellate review. Some arbitration clauses allow each side to choose one arbitrator, then those two select a third, forming a three-person panel. Others designate a single neutral arbitrator.

An experienced attorney can help you prepare for arbitration, present medical evidence, cross-examine the insurer's IME doctor, and argue damages in a persuasive manner.

Common Pitfalls and Coverage Traps

Exhaustion Requirement

Most UIM policies require you to exhaust the tortfeasor's liability limits before making a UIM claim. That means accepting a settlement from the at-fault driver's carrier and obtaining a full release. Settling for less than the policy limit—say, accepting $25,000 when the tortfeasor carried $30,000—may reduce your UIM recovery by the $5,000 you left on the table, or worse, bar the UIM claim entirely if the insurer can show you failed to maximize third-party recovery.

Always notify your UM/UIM carrier before settling with the tortfeasor. Many policies include a consent-to-settle provision requiring advance written approval.

Household-Vehicle Exclusion

Some UM/UIM endorsements exclude coverage when the uninsured vehicle is owned by someone in your household or when you are injured while occupying a vehicle you own but did not list on the policy. These exclusions prevent double-dipping—claiming UM/UIM on your sedan's policy for an injury caused by your spouse driving your unlisted pickup.

Texas courts have upheld household-vehicle exclusions if clearly drafted. The lesson: list every vehicle you own on one policy, or confirm that each vehicle's policy includes UM/UIM.

Phantom-Vehicle Claims

A phantom vehicle is an unidentified hit-and-run driver. UM coverage typically applies, but insurers impose strict proof requirements: corroborating witnesses, police reports filed within 24 or 48 hours, physical evidence of contact (paint transfer, debris), and sworn testimony.

Single-vehicle accidents attributed to phantom drivers—"a mystery car ran me off the road"—invite skepticism. Dashcam footage, independent witnesses, and contemporaneous 911 calls strengthen these claims dramatically.

Offset for Workers' Compensation and Government Benefits

When your injuries arise from a work-related crash and workers' compensation pays medical bills and disability benefits, your UM/UIM carrier may claim a credit for those payments under the policy's subrogation and offset clauses. Similarly, Medicare or Medicaid liens must be repaid from any UM/UIM settlement, reducing net recovery.

Texas law and federal regulations (particularly the Medicare Secondary Payer Act) govern these offsets. Ignoring a Medicare lien can subject you to double damages and jeopardize future benefits.

Comparative Negligence and UM/UIM Recovery

Texas follows a modified comparative-negligence rule (often called proportionate responsibility) under Texas Civil Practice & Remedies Code § 33.001. If you are found more than 50 percent at fault, you recover nothing. If you are 50 percent or less at fault, your recovery is reduced by your percentage of responsibility.

The same rule applies to UM/UIM claims. Suppose an uninsured driver runs a stop sign and hits you, but you were speeding 15 mph over the limit. An arbitrator finds you 30 percent at fault. Your $100,000 in damages is reduced to $70,000 before applying UM limits.

Insurers often argue comparative fault aggressively in UM/UIM arbitrations. Preserving evidence—photos, witness statements, electronic logging device (ELD) data in commercial-vehicle crashes—is critical.

UM/UIM in Rideshare and Commercial Crashes

Rideshare (Uber, Lyft)

Transportation Network Companies (TNCs) like Uber and Lyft carry substantial liability policies that apply when drivers are actively engaged in rideshare activity. Coverage levels vary depending on whether the driver has accepted a trip, is carrying a passenger, or is simply logged into the app awaiting a request. If an uninsured driver hits an occupied rideshare vehicle, the passenger may be able to tap the TNC's UM/UIM policy. Texas law treats TNC drivers as independent contractors, so the driver's personal UM/UIM usually excludes commercial use. Passengers should also check their own personal-auto UM/UIM, though most policies exclude coverage while occupying a vehicle used for hire.

Commercial Trucks and Fleet Vehicles

Federal Motor Carrier Safety Administration (FMCSA) regulations require interstate commercial carriers to maintain $750,000 to $5 million in liability insurance depending on cargo type. Despite these mandates, small trucking companies sometimes operate with lapsed coverage or fraudulent certificates of insurance.

When an uninsured or underinsured semi-truck causes a catastrophic injury, victims often pursue multiple defendants—the driver, the trucking company, the cargo broker, the leasing company. UM/UIM on your personal-auto policy may still apply, but recovery is capped at your per-person limit unless you carry a commercial or umbrella policy with higher UM/UIM.

Texas Department of Transportation (TxDOT) crash data show that large-truck collisions in 2022 caused 581 fatalities statewide, a five-year high. Many of those crashes involved owner-operators with minimal insurance.

Evaluating UM/UIM Limits: How Much Is Enough?

Financial planners and risk-management experts often recommend UM/UIM limits equal to or greater than your total liability limits. If you carry $250,000/$500,000 in liability to protect others, you should protect yourself with at least $250,000/$500,000 in UM/UIM.

Consider these benchmarks:

Scenario	Suggested UM/UIM Minimum
Single adult, modest assets, no dependents	$100,000 per person
Family with children, dual income, homeowner	$250,000 per person
High earner, significant savings, multiple vehicles	$500,000 per person or umbrella
Commercial driver, frequent highway use	$1,000,000 per person (commercial policy)

Umbrella policies—which sit above your auto and homeowners liability limits—often include excess UM/UIM. A $1 million umbrella with UM/UIM costs $200 to $400 annually and provides catastrophic protection against underinsured commercial vehicles or multi-car pileups.

Hit-and-Run and Phantom Drivers: Special Proof Rules

Texas UM policies typically cover hit-and-run crashes, but the burden of proof is high. You must show:

1. Physical contact between your vehicle and the phantom vehicle (or an object struck by the phantom vehicle).
2. Corroboration of the collision through independent witnesses or physical evidence.
3. Prompt police report, often within 24 to 72 hours.

Single-vehicle crashes with no witnesses and no debris are the hardest to prove. Dashcams, front and rear, have become invaluable. Some insurers offer discounts for dashcam installation precisely because footage deters fraud and speeds claims.

Texas Department of Public Safety (DPS) statistics indicate that a substantial percentage of Texas collisions involve a driver who fled the scene—thousands of hit-and-run crashes occur statewide each year.

Settlements, Releases, and Subrogation

Settlement Approval and Consent Clauses

Before accepting any settlement from the at-fault driver's liability carrier, read your UM/UIM policy's consent-to-settle clause. Many endorsements prohibit you from settling with a third party without the UM/UIM insurer's written consent. Violating this clause can forfeit your UIM claim entirely.

Best practice: notify your UM/UIM carrier in writing of any settlement negotiations, provide copies of demand letters and offers, and request written consent before signing a release.

Subrogation and Reimbursement

When your UM/UIM carrier pays your claim and you later recover additional funds from another source—a products-liability settlement against a vehicle manufacturer, a dram-shop claim against a bar that overserved the uninsured drunk driver—the insurer may assert a subrogation lien. Texas law permits contractual subrogation in first-party policies, though the "made whole" doctrine requires that you be fully compensated before the insurer recoups payments.

Subrogation disputes often arise in cases involving multiple defendants and layers of insurance. An attorney can negotiate lien reductions and protect your net recovery.

UM/UIM and Wrongful Death Claims

When an uninsured or underinsured driver causes a fatal crash, the decedent's UM/UIM coverage may provide the primary source of recovery for surviving family members. Texas Civil Practice & Remedies Code Chapter 71 authorizes wrongful-death claims by the spouse, children, and parents of the decedent. CPRC § 71.021 also permits a survival action for the decedent's estate, recovering pre-death pain and suffering, medical expenses, and lost earnings up to the moment of death.

UM/UIM policies cover both wrongful-death and survival damages, subject to the per-person and per-accident limits. In a family of four traveling together, each occupant may have a separate UM/UIM claim if all are injured or killed, but the total recovery is capped at the per-accident limit.

For example, if both parents die and two children are injured, and the family carried $100,000 per person / $300,000 per accident in UM, the maximum recovery is $300,000 total, allocated among the four claims. Stacking provisions, if present, can multiply coverage.

Navigating the Arbitration Hearing

Arbitration under a UM/UIM policy resembles a bench trial without a jury. Each side presents:

• Opening statements.
• Witness testimony: treating physicians, accident reconstructionists, vocational experts, the claimant.
• Documentary evidence: medical records, billing statements, employment records, police reports, photos.
• Expert reports: life-care plans for catastrophic injuries, economic analyses of lost earning capacity.
• Closing arguments.

Texas Rules of Evidence apply in most arbitrations unless the policy specifies otherwise. The arbitrator issues a written award, typically within 30 days. Grounds for overturning an arbitration award are narrow—fraud, evident partiality, or exceeding the arbitrator's powers—so thorough preparation is essential.

Policy Endorsements and Optional Riders

Stacking Endorsement

As discussed, a stacking rider allows you to combine UM/UIM limits across vehicles. Premium increase: typically 10 to 20 percent of the base UM/UIM cost.

Conversion Coverage

Some insurers offer a conversion endorsement that automatically increases your UIM limits if the at-fault driver's liability carrier becomes insolvent before paying the claim. This is rare but relevant in the wake of insurance-company bankruptcies.

Enhanced UM/UIM for Rideshare and Delivery Drivers

Drivers who work for Uber, Lyft, DoorDash, or Amazon Flex often need a commercial or hybrid policy. Standard personal-auto UM/UIM excludes coverage during "commercial use." Specialty insurers write rideshare endorsements that fill the gap during periods when TNC coverage is contingent or absent.

Interplay with Health Insurance and Medicaid

Private Health Insurance

Your health insurer pays medical bills as they accrue, then asserts a subrogation lien against any UM/UIM settlement. Under the Employee Retirement Income Security Act (ERISA), employer-sponsored health plans enjoy federal preemption and broad reimbursement rights. Negotiating ERISA liens requires knowledge of plan documents and Supreme Court precedent (e.g., US Airways v. McCutchen).

Medicaid (Texas Medicaid)

Texas Medicaid operates under Title XIX of the Social Security Act and asserts an automatic statutory lien against tort recoveries. The Texas Health and Human Services Commission (HHSC) must be notified of any settlement; failure to do so can trigger civil penalties. Medicaid's lien is dollar-for-dollar unless you can prove that the settlement does not fully compensate you for medical expenses, in which case a pro-rata reduction may apply.

Medicare

Medicare's lien rights are governed by the Medicare Secondary Payer Act. You must report any UM/UIM settlement of $5,000 or more to the Centers for Medicare & Medicaid Services (CMS) within specified timeframes. CMS calculates a conditional-payment amount and demands reimbursement. Overpaying or underpaying a Medicare lien can expose you to double damages.

Statute of Limitations and Limitations Periods

Texas Civil Practice & Remedies Code § 16.003 establishes a two-year statute of limitations for personal-injury and wrongful-death claims. This deadline applies to third-party tort suits against the uninsured driver.

UM/UIM claims are contract claims, so the limitations period is typically four years under CPRC § 16.004, but the policy may specify a shorter contractual limitations period—often two years from the date of the accident. Courts enforce these contractual limitations if the policy discloses them clearly.

Notice-of-claim provisions in UM/UIM endorsements may require you to submit a written claim within one year of the crash. Missing these deadlines can bar recovery entirely. Always calendar every deadline and consult an attorney early.

Selecting the Right UM/UIM Limits: Practical Steps

1. Review your current declarations page: confirm whether you have UM/UIM, the per-person and per-accident limits, and whether anti-stacking or household-exclusion clauses apply.
2. Compare your liability and UM/UIM limits: they should mirror each other at minimum.
3. Request quotes for higher limits: increasing from $30,000 to $100,000 per person often costs $50 to $150 annually—a bargain for five-figure downside protection.
4. Add an umbrella policy: if you own a home, have significant retirement savings, or face higher liability exposure, a $1 million umbrella with UM/UIM costs less than $1 per day.
5. Ask about stacking and Med-Pay coordination: clarify whether your policy allows stacking and how Med-Pay payments affect UM/UIM recovery.
6. Decline UM/UIM only after informed analysis: if cost is prohibitive, at least carry collision and Med-Pay; never drive uninsured entirely.

The Role of Legal Counsel in UM/UIM Claims

UM/UIM claims sound straightforward—submit bills, the insurer cuts a check—but insurers defend these claims as vigorously as third-party suits. They deploy:

• Independent medical examiners who minimize injury severity.
• Surveillance to catch claimants performing activities inconsistent with claimed disabilities.
• Recorded statements early in the claim, before you understand the full extent of injury.
• Low-ball offers that anchor settlement negotiations far below fair value.

An attorney experienced in UM/UIM arbitration will:

• Investigate alternative sources of coverage (umbrella, employer non-owned auto, additional tortfeasors).
• Secure expert testimony from treating physicians and economists.
• Draft detailed demand packages with life-care plans, lost-wage calculations, and day-in-the-life videos.
• Cross-examine the insurer's IME doctor and vocational expert.
• Negotiate lien reductions with health insurers, Medicare, and Medicaid.
• Represent you in arbitration or, if the policy permits, file a bad-faith lawsuit for wrongful denial.

Texas law allows recovery of attorney's fees in insurance bad-faith cases under CPRC § 38.001 and the Texas Insurance Code's prompt-payment and unfair-claims-settlement statutes. An insurer that delays or denies a valid UM/UIM claim without reasonable basis may owe 18 percent annual interest, attorney's fees, and in egregious cases, punitive damages.

Key Takeaways

• UM/UIM coverage is optional in Texas but must be offered: insurers must present limits equal to your liability limits; declining requires a written signature.
• Many Texas drivers are uninsured: making UM/UIM your financial safety net.
• UIM applies after the at-fault driver's liability limit is exhausted: most policies use a limits-minus-recovery formula; read your endorsement.
• Stacking can multiply recovery: anti-stacking clauses are common, but stacking riders are available for an incremental premium.
• Arbitration is standard: many UM/UIM policies require binding arbitration; prepare as you would for trial—witnesses, experts, exhibits.
• Exhaust third-party limits before claiming UIM: settling for less than the tortfeasor's policy limit can reduce or bar your UIM claim.
• Coordinate with Med-Pay, health insurance, Medicare, and Medicaid: offsets and liens can significantly erode net recovery; negotiate liens early.
• Statute of limitations: two years for the underlying tort, but the UM/UIM policy may impose a shorter contractual deadline; check your endorsement.
