One of the most important differences between a car accident claim and a truck accident claim is the amount of insurance involved. Federal law requires commercial trucking companies to carry significantly more liability insurance than the minimums required for passenger vehicles. Understanding those minimums — and how they work in practice — helps truck crash victims understand what compensation may actually be available to them.

Federal Minimum Insurance Requirements Under 49 CFR 387.9
The Federal Motor Carrier Safety Administration (FMCSA) sets minimum insurance requirements for commercial motor carriers under 49 CFR § 387.9, first established through the Motor Carrier Act of 1980. The required minimums vary depending on the type of cargo the truck is hauling:
- $750,000 — general freight carriers (the most common type of commercial truck)
- $1,000,000 — carriers transporting oil by truck
- $5,000,000 — carriers hauling hazardous materials listed under 49 CFR Part 172, Subpart F
- $300,000 — non-hazardous cargo carriers operating vehicles with a seating capacity of 15 or fewer passengers
These figures represent the minimum coverage floor. Many large trucking companies — particularly those moving high-value cargo or operating under shipper contracts — carry substantially higher policy limits, often $1,000,000 or more even for general freight. The federal minimums exist to ensure that at-fault carriers can pay for serious injuries; they do not cap what victims can recover from carriers with larger policies.
Illinois Intrastate Requirements: 625 ILCS 5/18c
Trucks that operate entirely within Illinois — without crossing state lines — fall under the Illinois Commercial Transportation Law, 625 ILCS 5/18c. Illinois largely mirrors the federal FMCSA minimums for intrastate commercial vehicles, but the Illinois Commerce Commission has authority to impose additional requirements on carriers operating under Illinois authority. Any truck large enough to require a commercial driver’s license and operating commercially within the state is subject to these requirements. A truck that crosses into Illinois from Indiana or Wisconsin — which covers the vast majority of interstate freight passing through Chicago — is governed by the federal FMCSA rules under 49 CFR Part 387.
The MCS-90 Endorsement: A Critical Victim Protection Mechanism
Beyond the basic policy limits, 49 CFR Part 387 requires that every motor carrier subject to federal financial responsibility rules attach an MCS-90 endorsement to its primary liability policy. The MCS-90 is not a separate insurance product — it is a mandatory endorsement that changes how the policy works in a specific and important way.
Under the MCS-90 endorsement, the insurer agrees to pay a judgment against the carrier up to the applicable federal minimum even if the carrier’s policy would otherwise exclude coverage. This means that if a carrier was operating outside the scope of its policy at the time of the crash — for example, because the driver was using the truck for an unpermitted purpose, or because the carrier failed to disclose the route — the insurer cannot use that exclusion to deny payment to an injured third party. The MCS-90 is a public protection measure, not a benefit to the carrier. Its purpose is to ensure that crash victims are not left with an uncollectable judgment simply because the carrier violated an internal policy condition.
Understanding liability in truck accidents requires looking at all available insurance coverage — the carrier’s primary policy, any MCS-90 endorsement obligations, umbrella or excess policies, and the insurance of any other potentially liable parties such as freight brokers or cargo loaders.
Why Truck Accident Claims Are Fundamentally Different from Car Accident Claims
In a typical car accident claim, Illinois requires drivers to carry a minimum of $25,000 per person and $50,000 per occurrence in bodily injury liability coverage under 625 ILCS 5/7-203. That coverage is frequently exhausted by a serious injury. Truck accidents operate in a different financial universe. A $750,000 federal minimum policy is thirty times higher than the standard car insurance floor. Carriers with $5,000,000 hazmat policies carry two hundred times the coverage.
This matters because truck accidents routinely produce catastrophic injuries — traumatic brain injuries, spinal cord damage, amputations, and fatalities — that generate economic losses far exceeding what a car insurance policy could cover. The higher federal minimums reflect Congressional recognition that a fully loaded commercial truck causes proportionally more damage than a passenger vehicle. They also mean that truck accident claims are worth investigating thoroughly, because the coverage available to pay a judgment is often substantial.
What Happens When the Carrier Is Underinsured or Uninsured?
Despite federal requirements, some carriers operate without proper insurance — particularly smaller, newer carriers that may allow their policies to lapse. In these situations, the MCS-90 endorsement provides a first layer of protection by obligating the insurer to pay victims even when the carrier failed to maintain continuous coverage. If the carrier has no insurance at all, victims may have additional claims against the freight broker who hired the carrier, the shipper who arranged the load, or the cargo owner who contracted for transportation. Illinois uninsured motorist coverage on the victim’s own auto policy may also apply in certain circumstances.

Identifying all available insurance coverage after a truck crash requires pulling policy declarations, reviewing MCS-90 endorsements, investigating whether the carrier had umbrella or excess coverage, and examining whether any other parties contributed to the crash and carry their own insurance. These are tasks that require access to information carriers and insurers do not volunteer.
