Commercial truck insurance requirements are unlike anything most accident victims have encountered before. Where a typical car accident involves one driver, one policy, and one insurance company, a truck accident can involve multiple policies, insurers, and defendants. These policies may all be active in the same case at the same time.
At Munley Law, the first step our truck accident lawyers take in any case is to map out every layer of available insurance coverage before making a single demand. Understanding this process and why it’s so important can make a significant difference in the outcome of your case.

Federal law requires trucking companies to carry minimum levels of commercial vehicle liability insurance. But those minimums are just the starting point. Large carriers often carry millions of dollars in additional coverage through excess and umbrella policies. Some of the biggest carriers in the country don’t use traditional insurance at all. Instead, they self-insure, meaning the company itself pays claims directly.
On top of that, multiple parties are typically involved in any commercial trucking operation, including:
- The driver
- The trucking company
- The cargo shipper
- The freight broker
- In some cases, the vehicle manufacturer
Each of those parties may carry its own separate insurance policy.
For truck accident victims, this isn’t a minor detail. It directly affects how much compensation is available, how long the claims process takes, and how aggressively the insurance companies will fight to limit what they pay out.
Federal Truck Insurance Minimum Requirements
The Federal Motor Carrier Safety Administration (FMCSA) sets the minimum insurance requirements for commercial trucks operating across state lines. These requirements are not optional. They are federal law, and carriers who fail to meet them can lose their operating authority.
The minimums vary based on what the truck is hauling and how much the vehicle weighs. Trucking companies must carry the following insurance coverage:
- $300,000: Minimum required coverage for non-hazardous freight carried by vehicles under 10,001 lbs
- $750,000: Minimum required coverage for non-hazardous freight carried by vehicles over 10,001 lbs
- $1,000,000: Minimum required coverage for hazardous materials (oils, gasoline, etc.)
- $5,000,000: Minimum required coverage for hazardous materials (explosives, radioactive material)
The $750,000 federal minimum is the number you’ll see most often cited in truck accident cases. Most fully loaded semi-trucks hauling general freight fall into that category. But you need to remember this: $750,000 is the floor, not the ceiling.
Many trucking companies, especially larger regional and national carriers, carry a $1 million trucking insurance policy in primary liability coverage. Some carry significantly more. As you’ll see below, primary coverage is only one piece of the puzzle.
It’s also worth noting that state laws can impose higher minimums in certain situations. If a carrier is operating entirely within one state, state-specific rules may apply instead of, or in addition to, federal requirements.
Here’s the unfortunate reality. In cases involving serious injuries like traumatic brain injury, spinal cord damage, permanent disability, or wrongful death, the economic damages alone can easily exceed $750,000. Medical bills, lost wages, long-term care, and loss of earning capacity add up quickly. That’s why knowing what coverage exists beyond the primary policy is so important.

How Layered Truck Insurance Coverage Works
Commercial truck insurance isn’t a single policy. It’s a system of coverage layers that activate in a specific order. Understanding how those truck accident insurance layers work helps explain why truck accident cases are handled differently than standard car accident claims. Here’s how the typical structure looks:
Primary Liability Policy: This is the first layer of coverage. It’s what pays out first when a claim is made. It must meet or exceed FMCSA minimums. When you hear “$750,000 policy,” this is usually what’s being referenced.
Excess Liability Policy: This layer activates after the primary policy is fully exhausted. If damages exceed the primary limit, the excess policy covers the remaining amount up to its own limit. Think of it as a second financial safety net stacked on top of the first.
Umbrella Policy: An umbrella policy is the broadest and typically the highest-dollar layer of coverage. It may also cover claims that fall into gaps between other policies. Large carriers often carry umbrella policies worth tens of millions of dollars.
Cargo Insurance: This covers damage to the freight itself, not to people. It’s a separate policy that typically won’t pay injury claims but does cover spills, hazardous materials, or cargo-related accidents.
Occupational Accident/Workers’ Compensation: This covers the truck driver if they’re injured. It does not provide compensation to accident victims, but it matters when determining the driver’s employment status.
In serious truck accidents, damages frequently exceed the primary policy limit. Without an attorney who knows how to access excess and umbrella coverage, victims may be offered a settlement based only on the first layer, leaving significant compensation on the table.
What Is an MCS-90 Endorsement in Truck Accident Claims?
If you’ve been researching truck accident insurance, you may have come across the term “MCS-90 endorsement.” It sounds technical, but the concept is straightforward, and it’s one of the most important protections available to truck accident victims.
An MCS-90 is a federally required endorsement attached to the insurance policy of any FMCSA-regulated motor carrier. Its purpose is simple: to ensure accident victims are compensated even when an insurer would otherwise have grounds to deny a claim.
Normally, if a carrier violates its own policy terms, for example, by using an excluded driver, the insurer can deny coverage. The MCS-90 removes that option. The insurer must pay eligible public claims regardless of internal policy violations.
What the MCS-90 doesn’t do is increase policy limits or create new coverage. It simply prevents insurers from using technicalities to avoid paying what federal law requires them to cover. Identifying whether it applies is a standard part of every truck accident case.
Excess and Umbrella Insurance Policies in Trucking Cases
As we touched on earlier, once a primary insurance policy’s limit is reached, the claim doesn’t stop. It moves to the next layer. That’s where excess and umbrella policies come in, and where the stakes of a truck accident case can increase significantly.
An excess liability policy works like a continuation of the primary policy. Once the primary limit is fully paid out, the excess policy activates and covers additional damages up to its own limit. It’s a direct extension of primary coverage.
An umbrella policy works similarly but is broader in scope. It may cover certain claims that fall outside the primary policy’s terms, and it typically carries much higher limits. A large national trucking carrier might carry an umbrella policy worth $25 million, $50 million, or more.
How Excess Liability and Umbrella Policies Affect Your Case
In practice, insurance companies that cover the primary policy want to close your case fast before anyone starts looking at the additional layers of coverage underneath. They may come to you early with a settlement offer that sounds reasonable. But that offer is often calculated to use up the primary policy limit and stop the process there, cutting you off from the more extensive coverage that may exist beyond it.
Experienced truck accident attorneys understand this tactic. Before entering into negotiations, a truck accident lawyer will evaluate the full scope of damages, which can include current and future medical costs, lost income, pain and suffering, and long-term disability. In catastrophic injury cases, that evaluation almost always points toward excess and umbrella coverage.
It’s also worth noting that when excess or umbrella coverage becomes relevant, those carriers often assign their own defense counsel. That means the victim may be facing multiple defense teams representing different layers of coverage simultaneously. That’s one reason why having dedicated legal representation is essential, not optional.
What Happens When a Trucking Company Is Self-Insured
Not every trucking company carries a traditional insurance policy. Some of the largest carriers in the country are approved by the FMCSA to self-insure. That means the company pays claims directly out of its own finances, with no third-party insurer involved. 
For accident victims, this matters. There are no traditional policy limits. The company itself decides how hard to fight your claim, and it has every financial incentive to pay as little as possible.
In litigation, attorneys shift focus from insurance documents to corporate financial records, internal claims procedures, and risk management practices. Self-insured carriers that unreasonably delay or deny valid claims may face bad faith liability in certain states.
Identifying whether a carrier is self-insured is one of the first things an experienced truck accident attorney needs to determine because it changes the legal strategy entirely.
How Insurance Structure Shapes Truck Accident Litigation Strategy
Knowing that insurance exists is one thing. Knowing how to use it strategically is another. In commercial truck accident cases, the insurance structure directly shapes every major litigation decision, from who gets named as a defendant to when and how settlement demands are made.
Here’s how it works in practice:
- Multiple defendants mean multiple policies. A fully loaded commercial truck may involve a driver, a trucking company, a freight broker, a cargo shipper, and a truck manufacturer. They are each potentially liable and may each carry separate insurance coverage. Naming the right defendants isn’t just about assigning blame. It’s about accessing every available source of compensation.
- Freight brokers carry their own liability coverage. Under recent FMCSA rulemakings, freight brokers who negligently select unsafe carriers can be held liable. Broker liability insurance in trucking cases is an often-overlooked source of coverage that experienced attorneys know to pursue.
- Excess carriers change the defense dynamic. When damages are large enough to threaten the primary policy limit, the excess insurer becomes actively involved in the defense. This often brings in new defense counsel and changes the settlement calculus entirely.
- Policy limits and punitive damages interact in important ways. Some insurance policies explicitly exclude punitive damages, which are damages awarded to punish egregious conduct. When punitive damages in a truck accident are likely, a separate legal strategy may be needed to pursue those damages against the carrier’s corporate assets directly. This is why trucking cases involving reckless conduct, hours-of-service violations under the FMCSA, or falsified records often look very different from standard negligence cases.
- Demand timing matters. Knowing the full insurance stack informs exactly when to make settlement demands and at what amount. Premature demands, made without a full picture of available coverage, can undercut a victim’s recovery.
How Attorneys Uncover Every Available Policy in Truck Accident Cases
In most car accident cases, insurance information is exchanged fairly quickly. Trucking cases are different. Coverage is often deliberately complicated, spread across multiple carriers, and not always volunteered by the defense.
Insurance discovery is the legal process of compelling the full disclosure of every policy that may apply to a truck accident claim. It’s one of the first and most important steps in any serious trucking case.
Here’s what that process looks like:
- Formal interrogatories: Written legal questions that the defendant must answer under oath, including detailed questions about every insurance policy in place at the time of the accident.
- Subpoenas to brokers and administrators: If a freight broker or third-party claims administrator is involved, attorneys can subpoena their records directly to identify coverage that the carrier hasn’t disclosed.
- FMCSA public insurance filings: Every FMCSA-regulated carrier is required to file proof of insurance with the agency. Those filings are publicly accessible and can confirm what coverage was in place and whether the carrier was compliant at the time of the crash.
- MCS-90 review: Attorneys review the carrier’s MCS-90 endorsement on file with the FMCSA to identify any attempts by insurers to use policy exclusions to avoid paying claims.
- Depositions of corporate risk managers: In larger cases, deposing the carrier’s internal risk management personnel can reveal additional coverage sources, claims handling procedures, and potential bad faith conduct.
Without thorough discovery, policies from freight brokers, shippers, truck lessors, and parent company umbrellas often go undetected. Insurers who conceal coverage or wrongfully deny claims risk bad faith liability. At Munley Law, we identify every layer before any settlement discussion begins.
When Truck Accident Damages Exceed Insurance Limits
It happens more often than most people realize: a victim suffers a catastrophic injury, and the damages far exceed what the primary policy covers. So what happens next?
The first step is accessing excess and umbrella coverage, which are designed precisely for high-value claims. From there, attorneys pursue all liable defendants, since each party in a trucking accident may carry their own separate policy. Combined, that coverage can be substantially higher than any single policy suggests.
When a trucking company’s conduct is reckless, its corporate assets can also become part of the recovery, not just its insurance. And when an insurer wrongfully refuses to settle within policy limits, bad faith claims can expose the insurer to liability beyond those limits entirely.
Policy limits are not the limits on recovery. They are the base limit. In serious cases, full compensation requires pursuing every layer and knowing how to get there.
How Truck Insurance Knowledge Drives Case Strategy
Commercial truck insurance is layered, regulated, and complicated by design. The insurers on the other side have full teams dedicated to limiting what they pay. Victims who don’t understand the full picture often settle for less than they deserve.
