When a commercial truck causes a catastrophic injury or wrongful death, one of the first questions in the case is how much insurance coverage is actually available. The policy a trucking company produces first is important, but it may not tell the entire story. Federal financial-responsibility requirements, state requirements, separate tractor and trailer coverage, broker-related coverage, contractual indemnity, and safety-net endorsements can all affect the coverage analysis.

Why the First Trucking Insurance Policy You Receive May Not Be the Only Coverage Available

A commercial trucking claim should begin with a coverage investigation, not simply a request for the carrier's primary policy. The available insurance can depend on whether the carrier was operating interstate or intrastate, the type of vehicle and cargo involved, the ownership and leasing structure, the identities of the motor carrier and broker, and the endorsements attached to the applicable policies.

For plaintiff's counsel, the practical point is straightforward: identifying the first policy is not the same as identifying all potentially available coverage. A catastrophic claim that stops with the first declarations page produced by a trucking company can leave additional sources of recovery unexplored.

Federal Minimum Insurance Requirements for Interstate Trucking

Federal motor-carrier regulations establish minimum financial-responsibility requirements for covered interstate operations. Under 49 C.F.R. § 387.7, a motor carrier subject to the federal requirements must maintain proof of financial responsibility through an approved mechanism, including an MCS-90 endorsement, an MCS-82 surety bond, or authorized self-insurance. The applicable minimum depends on the operation and cargo. The commonly encountered minimum for ordinary for-hire property carriers is $750,000, while higher minimums apply to specified passenger and hazardous-material operations. See 49 C.F.R. §§ 387.7, 387.9, 387.31, 387.33.

Those federal minimums are best understood as regulatory floors, not necessarily as the ceiling on coverage available in an individual case. The actual policy limits, excess or umbrella coverage, additional insured provisions, contractual indemnity, and applicable endorsements must still be investigated.

Texas Trucking Insurance Requirements: Minimum Coverage for Intrastate Carriers

Texas imposes its own financial-responsibility requirements on motor carriers operating within the state. TxDMV requires covered intrastate motor carriers to file proof of insurance, and 43 Tex. Admin. Code § 218.16 sets minimum automobile-liability insurance levels while incorporating federal Part 387 requirements for certain foreign commercial motor vehicles. The required amount depends on the type of operation and vehicle, so counsel should consult the current TxDMV requirements rather than assume that every Texas truck carries the same statutory minimum.

TxDMV also confirms that Texas intrastate motor carriers must maintain proof of insurance and that insurers electronically file the required insurance forms. See Tex. Dep't of Motor Vehicles, Becoming a Texas Motor Carrier (Intrastate); 43 Tex. Admin. Code § 218.16.

What Is an MCS-90? Understanding the Federal Trucking Insurance Safety Net

The MCS-90 is frequently misunderstood. It is not simply another policy limit sitting on top of a motor carrier's liability policy. Instead, it operates as a federally required endorsement that can obligate an insurer to pay certain final judgments involving public liability even when the underlying policy would not otherwise provide coverage for the particular vehicle or operation.

Courts have described the MCS-90 as a safety net for the public. In T.H.E. Insurance Co. v. Larsen Intermodal Services, Inc., 242 F.3d 667, 671–72 (5th Cir. 2001), the Fifth Circuit characterized the endorsement as a form of suretyship protecting the public when other coverage is lacking. See also S. County Mut. Ins. Co. v. Great W. Cas. Co., 436 S.W.3d 348, 350–51 (Tex. App. Waco 2014, no pet.) (quoting 49 C.F.R. § 387.15).

What Is Form F? Understanding Texas's Motor Carrier Insurance Safety Net

Texas has its own motor-carrier insurance filings, including Form E and Form F. Texas courts have described Form F as insurance of last resort when no other insurance would otherwise be available. See Nat'l Cas. Co. v. Lane Express, Inc., 998 S.W.2d 256, 263 (Tex. App. Dallas 1999, pet. denied).

Because the effect of a Form F filing depends on the applicable regulatory and policy framework, counsel should obtain the actual filing and the underlying policy rather than assume that a Form F automatically creates an independent policy limit. The key investigative question is whether the filing creates an obligation to protect the public when ordinary coverage is unavailable or disputed.

Why a Truck Accident May Involve Multiple Insurance Policies

The tractor and trailer may be owned by different entities and insured under separate policies. The motor carrier may have its own primary automobile liability policy, while an owner, lessor, or other entity has additional coverage that must be evaluated under the facts and policy language.

The same principle applies to freight brokers and other participants in the transportation chain. A broker may have its own liability coverage, contractual indemnity rights, additional-insured provisions, or other insurance that becomes relevant if the broker is sued for negligent hiring or another independent theory of liability.

The existence of another policy does not mean that the policy necessarily covers the plaintiff's claim. Coverage depends on the policy language, endorsements, insured status, exclusions, applicable law, and the liability theories asserted. The point is that each potential policy should be identified and analyzed before counsel concludes that the available coverage has been exhausted.

Can a Freight Broker's Insurance Policy Provide Additional Coverage After a Truck Crash?

The Supreme Court's May 14, 2026, decision in Montgomery v. Caribe Transport II, LLC, 608 U.S. (2026), is particularly important for cases involving freight brokers. The Court held unanimously that a state-law negligent-hiring claim against an interstate freight broker falls within the Federal Aviation Administration Authorization Act's safety exception and therefore is not preempted by 49 U.S.C. § 14501(c).

The decision matters because it preserves a pathway for plaintiffs to pursue the merits of negligent-hiring claims against interstate brokers. It does not make brokers insurers of every accident, however. The Court's opinion addresses preemption. The ultimate merits of a negligent-hiring claim remain dependent on the applicable state law and facts, including whether the broker exercised reasonable care in selecting the carrier.

For plaintiff's counsel, the coverage implication is practical. If a broker can be a viable defendant in an interstate trucking case, counsel should not limit the insurance investigation to the motor carrier. The broker's liability policy, additional insured arrangements, contractual indemnity provisions, and other potentially applicable coverage should be identified and evaluated.

How Attorneys Can Investigate All Available Truck Accident Insurance Coverage

A thorough coverage investigation should be conducted early, preferably before the case is filed or before settlement discussions become focused on a single policy. Depending on the facts, counsel should consider obtaining:

  • The motor carrier's complete liability policy, including declarations, endorsements, exclusions, and MCS-90 or other applicable filings.
  • Separate policies covering the tractor, trailer, owner, lessor, or other vehicle interests.
  • Excess and umbrella policies and the applicable attachment points.
  • Brokerage agreements, shipper agreements, and indemnity provisions.
  • The freight broker's liability policies and endorsements, including any additional-insured provisions.
  • Texas Form E and Form F filings when applicable.
  • Federal motor-carrier financial-responsibility filings and FMCSA registration information.
  • Leases, equipment agreements, and contracts identifying the entities responsible for insurance and indemnity.
  • Documentation concerning the carrier-selection process, including safety records and the broker's due diligence.

The investigation should also distinguish between the existence of a policy and the availability of coverage for the particular claim. A declarations page may establish limits, but the actual policy language and endorsements determine whether those limits are potentially available.

Working with Trained Truck Crash Counsel

Commercial truck accident cases often involve a more complicated insurance structure than the first policy produced by the trucking company suggests. Federal and Texas financial-responsibility requirements, MCS-90 and Form F filings, separate vehicle policies, broker liability, indemnity agreements, and excess coverage can all affect the available recovery.

For attorneys handling catastrophic truck accident claims, the coverage investigation should begin early and extend beyond the motor carrier's primary policy. A complete coverage map can materially affect case valuation, litigation strategy, settlement negotiations, and the decision about which entities should be named as defendants.

If you are handling a catastrophic commercial truck accident and need assistance identifying potential layers of insurance coverage or evaluating broker-related liability, counsel experienced in trucking litigation may open the door to significantly greater coverage available to compensate your client.
