MCS-90 endorsement and the $750,000 truck insurance minimum

A loaded tractor-trailer drifts across the center line on U.S. 17, and in a few seconds an ordinary drive becomes months of surgery and missed work. Once the first weeks pass, injury victims and their families start asking a practical question: how much insurance does a trucking company actually have, and what happens if its insurer says the policy doesn’t apply?

Federal law answers part of that question with a one-page form attached to most interstate trucking policies. I’m Robert L Armstrong, and I have represented injury victims and their families in the Wilmington area for over 41 years. This guide explains what that form guarantees, the federal and North Carolina minimum limits, how to look up a carrier’s insurance yourself, and where additional coverage can come from when the minimum is not enough.

What the MCS-90 endorsement is

Most of the tractor-trailer cases I see involve a motor carrier that hauls freight across state lines, and almost every one of those carriers has an MCS-90 on its liability policy. The name comes from the form’s full title: “Endorsement for Motor Carrier Policies of Insurance for Public Liability under Sections 29 and 30 of the Motor Carrier Act of 1980.” An endorsement is an amendment to an insurance policy. Federal regulation 49 CFR 387.15 requires it to be in the form the Federal Motor Carrier Safety Administration (FMCSA) prescribes.

The MCS-90 form is not ordinary coverage. It works more like a surety bond, which is a promise to the public that a minimum amount of money will be there. Under its terms, the insurer agrees to pay any final judgment against the trucking company for bodily injury, property damage, or environmental cleanup caused by negligent operation of its trucks. That promise holds whether or not the specific truck is listed on the policy, and whether or not the crash happened on an authorized route.

Why the endorsement matters when an insurer denies coverage

Here is the sentence on the form I explain most often. No condition, exclusion, or violation of the policy relieves the insurer of paying a final judgment within the required limits, regardless of the trucking company’s financial condition or bankruptcy. So if the policy would exclude the claim because the truck wasn’t scheduled, the driver wasn’t approved, or the carrier missed a premium payment, the endorsement can still require the insurer to pay the injury victim up to the federal minimum.

The insurer doesn’t simply absorb that loss. The form makes the trucking company agree to reimburse the insurer for any payment it would not have owed under the policy alone. That reimbursement fight is between the insurer and the carrier. It isn’t the injury victim’s problem.

What the MCS-90 does not cover

The endorsement has limits of its own. It does not cover injury or death of the trucking company’s own employees on the job, and it does not cover the cargo. It pays final judgments, so it usually stays in the background during negotiation and matters most when coverage is disputed. Most courts also treat it as a safety net that applies only when other insurance fails to pay the federal minimum, and they generally cap the endorsement’s obligation at that minimum, not the full policy limit.

When the MCS-90 applies and when it doesn’t

Under 49 CFR 387.3, the federal financial responsibility rules apply to for-hire carriers hauling property in interstate or foreign commerce, and to carriers of certain hazardous materials, whether for-hire or private. Trucks with a gross vehicle weight rating under 10,001 pounds are exempt unless they carry specific high-risk hazardous materials.

That leaves several gaps worth knowing about:

• Purely in-state trips. Courts have split on whether the endorsement reaches a crash during an intrastate haul, so the facts of the trip matter.
• Private fleets hauling ordinary goods. A company moving its own nonhazardous products in its own trucks is not a for-hire carrier, so the federal property minimum doesn’t apply to it the same way.
• Smaller vans and box trucks. Many delivery truck crashes involve vehicles under the 10,001-pound line, where contractor arrangements and ordinary auto policies decide what coverage exists.
• Self-insured carriers. Some large carriers get FMCSA approval to self-insure under 49 CFR 387.309. They file proof of financial strength instead of an insurance policy, so there may be no MCS-90 at all, and the carrier itself pays.

Passenger carriers have their own endorsement and higher minimums. Under 49 CFR 387.33, for-hire interstate buses with 16 or more seats including the driver must carry $5,000,000, and vehicles with 15 or fewer seats must carry $1,500,000.

Federal minimum insurance limits under 49 CFR 387.9

The federal minimums depend on what the truck is hauling. These amounts apply to vehicles with a gross vehicle weight rating of 10,001 pounds or more unless noted.

Type of carriage	Cargo	Minimum limit
For-hire, interstate or foreign	General freight (nonhazardous property)	$750,000
For-hire or private, interstate or intrastate in bulk	Oil and hazardous materials not listed in the $5,000,000 tier	$1,000,000
For-hire or private, interstate, foreign, or intrastate	Hazardous substances in bulk tanks or hopper vehicles, bulk explosives, bulk poison-inhalation materials, bulk flammable or compressed gases, and highway route controlled radioactive shipments	$5,000,000
For-hire or private, interstate or foreign, under 10,001 lbs	Any quantity of certain explosives, poison-inhalation materials, or highway route controlled radioactive shipments	$5,000,000

North Carolina’s rule for commercial trucks

North Carolina adds its own floor. Under G.S. 20-309, subsection (a1), the owner of a commercial motor vehicle must carry financial responsibility equal to the federal amount for for-hire interstate carriers of nonhazardous property, which is $750,000. North Carolina’s definition of a commercial motor vehicle in G.S. 20-4.01(3d) includes Class A combinations of at least 26,001 pounds, Class B vehicles, vehicles designed to carry 16 or more passengers, and placarded hazmat vehicles. For comparison, the minimum liability limit on a passenger car policy in North Carolina is $50,000 per person.

Why $750,000 often falls short after a serious truck crash

The $750,000 minimum for general freight took effect January 1, 1985, and it has not been raised since. Medical bills, wages, and the cost of long-term care have all risen sharply in that period, while the floor has stayed at the same dollar figure.

The injuries in truck crashes are also more severe than in most car crashes. The Insurance Institute for Highway Safety reports that 5,340 people died in large truck crashes in 2024, and 62% of them were occupants of cars and other passenger vehicles. A spinal cord injury, brain injury, or death can produce lifetime losses well beyond $750,000, especially when more than one person is hurt in the same crash and every injured person draws from the same per-accident limit.

That is why I treat the minimum as the starting point of the coverage analysis, not the answer. When a crash causes a death, the same layers apply to a wrongful death claim brought by the family through the estate.

How to look up a trucking company’s insurance

Federal law treats a carrier’s proof of financial responsibility as public information, and much of it is online. You can start the search yourself with the USDOT number painted on the side of the truck’s cab, which is one reason I suggest photographing it at the scene.

1. Get the USDOT number. It is usually on the cab door and is often in the crash report too.
2. Check the company snapshot. The FMCSA SAFER system shows the carrier’s legal name, operating status, cargo types, and whether it is authorized for interstate or intrastate work.
3. Search the Licensing and Insurance records. The FMCSA insurance lookup lets you search by USDOT or MC number to see active insurance filings, the insurer’s name, the policy number, and the coverage amount on file, plus the filing history.
4. Compare the dates. A cancellation or lapse near the crash date is a red flag, and it is exactly the situation the MCS-90 was written for.

Keep in mind what the public filing leaves out. It often shows only the amount the carrier filed to meet the federal minimum. Excess and umbrella policies usually don’t appear, and the only reliable way to find them is through written requests to the insurer and, if a lawsuit is filed, formal discovery. My truck accident checklist covers the scene photos and records that make this lookup easier.

Excess, umbrella, and other layers of coverage

Many carriers buy more than the minimum. A typical layered program has a primary policy that pays first and one or more excess or umbrella policies that pay after the primary limit is used up. Those excess layers have their own policy terms, and the MCS-90 does not guarantee them, so the exclusions in each layer have to be read separately.

Other companies can add coverage too. A truck case often involves a driver, a motor carrier, a trailer owner, a maintenance shop, a shipper or loader, and sometimes a freight broker. If more than one of them shares fault, each may carry its own policy. Sorting out who is responsible is also a defense against North Carolina’s contributory negligence rule, which can bar recovery entirely if the injury victim is found even slightly at fault, so the evidence of how the crash happened matters at every layer.

Using your own UM and UIM coverage on top of the truck’s insurance

When the trucking company’s coverage runs out, the injury victim’s own auto policy may help. North Carolina changed its underinsured motorist rules for policies issued or renewed on or after July 1, 2025. Under the current version of G.S. 20-279.21, a vehicle counts as underinsured when its liability limits are less than the injured person’s total damages, and the underinsured coverage is not reduced by a credit for the liability insurance that already paid.

In practical terms, if a truck carries $750,000 and your damages are well above that, your own underinsured motorist coverage can pay on top of the truck’s limit once that limit is exhausted. The statute also allows coverage from separate policies under which you are an insured to be combined, so a household with more than one policy may have more coverage than it realizes. My guide to an underinsured motorist claim explains the notice and timing steps. Uninsured motorist coverage can also matter if the carrier turns out to have no valid insurance at all.

MCS-90 and truck insurance FAQs

Does the MCS-90 endorsement mean the trucking company has $750,000 in coverage? ▶

Not exactly. The endorsement guarantees that a final judgment for injuries to the public will be paid up to the federal minimum for that type of cargo, even when the policy would otherwise exclude the claim. The actual policy may carry higher limits, and excess policies may sit on top. The only way to know the full amount is to find every policy, which usually starts with the carrier’s FMCSA filings.

Can I make a claim directly against the MCS-90? ▶

Usually not at the start. The MCS-90 pays a final judgment against the insured trucking company, so it comes into play after a claim is proven or when the insurer is trying to deny coverage under the policy. In most cases, the claim runs against the trucking company and its insurer first, and the endorsement stays in the background as a guarantee.

What if the truck was only driving inside North Carolina? ▶

The federal MCS-90 rules focus on interstate trucking, so a purely in-state haul can fall outside them. North Carolina law still requires owners of commercial motor vehicles registered here to carry financial responsibility equal to the $750,000 federal minimum. Which rule applies depends on the trip, the cargo, and where the truck is registered, and I sort that out early in a case.

The trucking company’s insurer called me. Should I tell them about my own insurance? ▶

You can confirm basic facts, but you don’t have to give the trucking company’s insurer a recorded statement or details about your household policies. Your own underinsured motorist coverage is your claim, not theirs, and the order in which policies pay matters. I handle those conversations for my clients so nothing is said that narrows the coverage later.

How long do I have to bring a claim after a truck crash in North Carolina? ▶

Most personal injury claims in North Carolina must be filed within three years of the crash, and wrongful death claims within two years of the death. Coverage questions take time to sort out, and trucking records can be discarded much sooner than that, so an early review gives you the most options.

What does it cost to have you review the trucking company’s insurance? ▶

The consultation is free, and there is no fee unless I win. During that first conversation I look at what you know about the truck and the company, explain what the federal filings are likely to show, and tell you plainly what I see. I also explain how case costs are handled before you decide anything.
