How Much Insurance Must a Semi-Truck Carry in Mississippi?
Key Takeaways: Most interstate semi-trucks hauling general freight through Mississippi must carry at least $750,000 in liability coverage, and trucks hauling certain hazardous materials may need up to $5,000,000 under 49 CFR Part 387. Mississippi does not set its own amounts for interstate carriers. Instead, Miss. Code Ann. § 77-7-87 ties required coverage to these federal minimums, and vehicles generally must also meet the state baseline under Miss. Code Ann. § 63-15-4. These figures are floors, not caps. The $750,000 general freight minimum has not gone up since the 1980s, so serious injuries can exceed available coverage. Victims may find more money through excess or umbrella policies, other liable parties, or their own underinsured motorist coverage. Saving evidence early and meeting filing deadlines, generally three years in Mississippi and one year in Tennessee, can be key to recovery.
Most interstate semi-trucks hauling general freight through Jackson must carry at least $750,000 in liability coverage, and trucks hauling certain hazardous materials may need up to $5,000,000. Mississippi does not set its own dollar amounts for interstate carriers. Under Miss. Code Ann. § 77-7-87, the minimum coverage must match what federal law requires in 49 CFR Part 387. If you or someone you love was hurt in a crash with an 18-wheeler, these numbers often decide how much money is available to pay for medical care, lost income, and long-term needs.

Why the Law Treats Semi-Trucks Differently Than Cars
Federal and state law generally require semi-trucks to carry much more insurance than cars because truck crashes can cause far more harm. A fully loaded tractor-trailer can weigh many times more than a family car, and the injuries are often severe. Lawmakers set higher insurance floors to help make sure injured people have some source of payment.
The State Baseline for Every Vehicle
Motor vehicles on Mississippi roads generally must have liability insurance that meets state minimum limits, with some exemptions. Miss. Code Ann. § 63-15-4(2)(a) says every vehicle operated in the state "shall have a motor vehicle liability insurance policy" that meets the limits in Miss. Code Ann. § 63-15-3(j). For interstate commercial trucks, this state baseline sits well below the federal minimums.
The Federal Layer for Interstate Carriers
The Federal Motor Carrier Safety Administration (FMCSA) requires interstate motor carriers to keep minimum levels of insurance. The required amount depends on the type of vehicle and the cargo it carries. Carriers generally must file proof of coverage with the agency, and FMCSA explains these insurance filing requirements for carriers that cross state lines. A truck passing through Jackson typically faces the same federal floor as one in Memphis or Dallas. Trucks operating only within Mississippi may face different state rules.
Commercial Truck Insurance Requirements by Cargo
Commercial truck insurance requirements generally rise with the danger of what the truck is hauling. The federal rules at 49 CFR Part 387 set out the exact amounts. The table below sums up the general framework.
| Coverage Layer | Who It Generally Applies To | Minimum Amount |
|---|---|---|
| Mississippi state minimum | Most motor vehicles operated in Mississippi, with some exemptions | Limits in Miss. Code Ann. § 63-15-3(j) |
| Federal general freight minimum | Interstate for-hire carriers hauling non-hazardous property in vehicles rated 10,001 pounds or more | $750,000 |
| Federal hazardous materials minimum | Carriers hauling certain hazardous materials, oil, or hazardous waste | $1,000,000 to $5,000,000, depending on the material |
These figures are minimums, not caps. Many motor carriers buy more coverage than the law requires, and some carry excess or umbrella policies. Finding every layer of coverage can make a big difference in a serious injury claim.
💡 Pro Tip: Ask your attorney to request the carrier’s full insurance file, including any excess or umbrella policies. The main policy is often only part of the available coverage.
How Mississippi Law Connects to Federal Limits
Miss. Code Ann. § 77-7-87 is the main link between Mississippi law and federal trucking liability limits. The statute requires each interstate motor carrier to "file and keep on file with the commission" a policy or certificate of insurance, a bond, or proof that it qualifies as a self-insurer. That filing must meet the rules of the federal single state insurance registration program, and the minimum amount must equal what 49 CFR Part 387 requires.
Who the Required Coverage Protects
The required coverage generally must pay final judgments for injuries and property damage suffered by members of the public. Under Miss. Code Ann. § 77-7-87, the coverage must pay any final judgment against the interstate carrier for personal injury or property damage arising from the use, upkeep, or operation of its vehicles. For Jackson crash victims, this generally means a source of payment exists, though recovery still depends on proving fault and damages. The statute does not require carriers to file coverage for claims by their own passengers, shippers, or customers.
Insurance Cards and Self-Insured Fleets
Since July 1, 2013, insurers have had to give commercial auto customers an insurance card clearly marked "Commercial Auto Insurance" or "Fleet" or similar wording. Miss. Code Ann. § 63-15-4(2)(b) sets out this rule. The marking can help police and crash victims see quickly that a truck has a commercial policy. Breaking the insurance rules of Miss. Code Ann. § 63-15-4 is a misdemeanor that may bring a fine and suspension of driving privileges.
Some vehicles do not need the card. Under Miss. Code Ann. § 63-15-4, these include vehicles with a qualifying bond or certificate of deposit on file and vehicles that are self-insured under Miss. Code Ann. § 63-15-53. Some large fleets meet their duties through self-insurance instead of a standard policy, and it can then take more digging to find out who actually pays a claim.
Is $750,000 Enough to Cover a Serious Truck Crash?
In many severe cases, $750,000 may not cover the full cost of a victim’s losses. The federal minimum for general freight was set in the 1980s and has not gone up since, despite decades of inflation and rising medical costs. Advocacy groups focused on truck safety have long argued that the $750,000 floor is inadequate to cover the costs of a catastrophic crash.
Lifetime care for a brain or spinal cord injury can quickly exceed the federal minimum. When a claim is worth more than the available coverage, your legal team may need to look beyond the carrier’s main policy. You can read more about pushing for full coverage after a truck crash. Other possible sources of payment may include:
- Excess or umbrella insurance policies held by the motor carrier
- Separate policies covering a cargo loader, shipper, or maintenance company
- Coverage held by a broker or trailer owner, depending on the facts
- Your own underinsured motorist coverage, subject to policy terms
Protecting Your Claim After a Mississippi Truck Accident
The insurance amount generally matters only if you can show the truck driver or another party was at fault. Mississippi follows pure comparative negligence, so any award may be reduced by your own share of fault. Key evidence, such as electronic logging device data, driver hours records, and maintenance files, can be lost or overwritten if no one acts to save it. Sending a preservation letter early may help protect this evidence.
Deadlines also affect your ability to recover. In Mississippi, many personal injury claims generally must be filed within three years under Miss. Code Ann. § 15-1-49, with some exceptions. If your crash happened across the state line in Tennessee, the deadline is generally only one year under Tenn. Code Ann. § 28-3-104. Claims against government entities may have separate, shorter rules.
💡 Pro Tip: Photograph the truck’s USDOT number and company name at the scene if you safely can. This helps your legal team find the carrier’s federal insurance filings.
Every truck crash case is different, and outcomes depend on the facts. Mama Justice Law Firm recently secured a $112,500 personal injury settlement in Mississippi.

1. What is the federal minimum insurance for a semi-truck?
For interstate for-hire carriers hauling general freight, the federal minimum is generally $750,000. Carriers hauling certain hazardous materials may need $1,000,000 to $5,000,000 under 49 CFR Part 387.
2. Does Mississippi require more than the federal minimum?
Mississippi generally adopts the federal minimums for interstate carriers rather than setting higher amounts. Miss. Code Ann. § 77-7-87 ties the required coverage to 49 CFR Part 387. Vehicles must also meet the state baseline under Miss. Code Ann. § 63-15-4.
3. What happens if my damages exceed the truck’s insurance?
You may be able to seek other sources of payment, depending on the facts. These could include excess policies, other liable parties, or your own underinsured motorist coverage. Collecting beyond available insurance can be hard, so finding all coverage early often matters.
4. Can a trucking company be self-insured in Mississippi?
Yes, in some cases a carrier may qualify as a self-insurer. Miss. Code Ann. § 77-7-87 allows interstate carriers to file proof that they qualify as self-insurers. Self-insured fleets may also be exempt from the insurance card rule under Miss. Code Ann. § 63-15-4.
5. How do I find out what insurance a truck carried?
The carrier’s federal filings and the police report are common starting points. Your attorney may also request policy information from the carrier or through discovery.
Know the Coverage Before You Negotiate
Commercial truck insurance requirements set a floor, but they do not tell you what your claim is truly worth. Federal law generally requires $750,000 for general freight and up to $5,000,000 for certain hazardous cargo, and Mississippi generally adopts those amounts for interstate carriers through Miss. Code Ann. § 77-7-87. Because the federal minimum has not gone up since the 1980s, serious injuries can exceed available coverage. Finding every policy, saving evidence, and meeting filing deadlines can all affect your recovery.
