Hazmat trucking insurance requirements: the federal minimums

Hazmat trucking insurance requirements start higher than the rules for general freight. If you are thinking about hauling hazardous materials, the first number to know is the federal minimum for liability insurance. It changes with what you haul. Here is how the federal rule works, in plain words, and what to check before you book your first hazmat load.

What hazmat means

Hazmat is short for hazardous materials. These are products that can harm people, property or the environment if they spill, leak, burn or explode. Think of fuels, many chemicals, compressed gases, explosives and radioactive materials. The U.S. Department of Transportation lists them and sorts them into classes and divisions.

Where the rule is

The federal rule is 49 CFR 387.9. It sets the minimum level of financial responsibility, or liability insurance, that motor carriers must have. Liability is the part of your policy that pays for harm you cause to other people and their property.

These numbers are minimums. They are the least the law accepts. They are not advice on what you should buy.

The three main levels

For trucks with a GVWR of 10,001 pounds or more (GVWR is the maximum loaded weight the maker rates the truck for), the rule has three main levels:

• $750,000 for a for-hire carrier hauling nonhazardous property in interstate commerce. This is the general freight minimum. Our article on $750,000 vs $1 million limits explains why many brokers ask for more.
• $1,000,000 for oil listed in the federal hazmat table, and for hazardous waste, hazardous materials and hazardous substances that are not in the $5 million group. In interstate commerce this applies in any quantity. In intrastate commerce it applies to bulk loads only.
• $5,000,000 for the most dangerous loads. This group includes hazardous substances hauled in bulk in cargo tanks, portable tanks or hopper-type vehicles; bulk explosives in Divisions 1.1, 1.2 and 1.3; bulk poison gases in Division 2.3 Hazard Zone A; bulk Division 6.1 Packing Group I Hazard Zone A materials; bulk flammable and nonflammable gases in Divisions 2.1 and 2.2; and highway route controlled quantities of radioactive (Class 7) materials.

The rule also sets a $5 million minimum for some of these same dangerous materials when they move in smaller trucks, under 10,001 pounds GVWR, in interstate commerce.

Hazmat trucking insurance requirements: why the details matter

The rows in the rule have conditions: the type of material, whether it is in bulk, the tank size, and interstate or intrastate. The same product can fall in a different row depending on how it moves. So the safe way to know your minimum is to read the rule with the exact shipping description of the load in your hand.

Your broker or shipper contract can also ask for more than the federal minimum. Read it.

What to check before you book a hazmat load

1. Get the shipping papers or the exact product description. The class, division and packing group tell you which row applies.
2. Ask: bulk or not bulk? Bulk tanks and hoppers often move you into a higher row.
3. Check your current limit on your declarations page, the summary page at the front of your policy.
4. Read the contract. The broker or shipper may require more.
5. Talk to your agent before you accept the load, not after. Changing a policy can take time.

Mistakes to avoid

• Assuming your general freight policy works for hazmat. The minimum can be higher, and policies can have their own rules about hazmat.
• Guessing the row. Read the rule with the real product description.
• Booking first, asking later. Your limit has to be right before the load moves.
• Forgetting cleanup risk. Spills bring their own questions. Our article on pollution coverage for trucking explains them.

Common questions

What is the minimum insurance to haul hazmat? It depends on the material and how it moves. Under 49 CFR 387.9, it is $1 million for oil and many hazardous materials and $5 million for the most dangerous bulk loads.

Is $750,000 enough for any hazmat load? The $750,000 row is for nonhazardous property. Hazmat loads fall in the $1 million or $5 million rows.

Do brokers ask for more than the federal minimum? Many do. Each broker or shipper sets its own number in the contract.
