Dump Truck Insurance

Which rules apply to your dump truck

• CDL. Class B for a truck rated 26,001 lb or more; Class A when you pull a pup trailer over 10,000 lb with a combined rating of 26,001 lb or more. CDL rules apply inside your state too.^[1][2]
• Interstate for-hire hauling. Sand, gravel, rock and topsoil are not exempt commodities, so hauling them for hire across state lines takes MC authority and a $750,000 liability filing.^[3][4]
• Contractors hauling their own materials. A private carrier needs a USDOT number for interstate trips but has no federal dollar minimum.^[5]
• Staying in one state. The state sets the rules. Washington requires USDOT numbers on intrastate commercial vehicles.^[6] California requires a Motor Carrier Permit for anyone paid to haul property and for trucks over 10,000 lb, with liability from $300,000 to $5,000,000 depending on the truck and load.^[7] In Texas you get a USDOT number first, then state authority.^[8]
• IFTA. Trucks with three or more axles need IFTA credentials at any weight when they run interstate.^[9]
• Hours of service. Construction-materials hauling to or from an active site within 75 air-miles gets a 24-hour restart; states may set 50 to 75 miles for intrastate trips.^[10][11] The 150 air-mile short-haul exception also applies.^[10]

What contracts usually require

Construction contracts often set higher limits than the law. Colorado DOT’s standard requirements, for example, call for:^[12]

• “Any auto” liability (owned, hired and non-owned) at $1,000,000 combined single limit
• $1,000,000 per occurrence general liability
• The owner named as additional insured on both policies, a waiver of subrogation and primary wording

Additional insured status lets the contractor or owner claim under your policy for your work. A waiver of subrogation stops your insurer from suing them to recover what it paid.^[13] Send us the insurance section of your contract with your quote request.

Coverages a dump truck operation needs

• Auto liability. Covers injury and damage from driving and from dumping, which counts as use of the truck.^[14] Rocks that crack another driver’s windshield are a liability claim, not a cargo claim.
• General liability. Covers work that isn’t use of the truck, such as spreading or grading with equipment.^[14] Most job sites require it.
• Physical damage. Include the dump body, hoist and tarp system in the stated value. Collision coverage includes overturn, so a tip-over while dumping is normally a collision claim.
• Cargo. Federally required only for household goods.^[15] For aggregate, it’s usually a contract question.
• Hired and non-owned auto if you use subhaulers, and non-trucking liability if you’re leased on.
• Workers’ comp or occupational accident for drivers. NIOSH counted 809 construction and extraction workers killed in dump truck incidents from 2011 to 2020, mostly struck-by, tip-over, crushing, electrical and fall incidents.^[16]

Tarp laws and weight limits

Covered-load rules vary by state:

• California: aggregate must be covered unless the load stays 6 inches below the top edge.^[17]
• Washington: dirt, sand or gravel may run uncovered only with 6 inches of freeboard. If a falling load seriously injures someone, it becomes a gross misdemeanor.^[18]
• Texas: loose-material loads on commercial trucks must be covered and secured, with fines of $25 to $500.^[19]
• Florida: a close-fitting tarp or a securement device that meets federal cargo securement rules.^[20]

On the Interstate, limits are 20,000 lb on a single axle, 34,000 lb on a tandem and 80,000 lb gross, subject to the Bridge Formula, and some states allow more under grandfather rules.^[21]

What to have ready for a dump truck quote

• USDOT number, any MC or state authority, and whether you haul for hire or your own materials
• Body type (end, side, belly, tri-axle, with or without a pup), year, VIN and value
• What you haul by percentage (sand, gravel, asphalt, demolition debris) and your radius
• How much time you spend on job sites versus highways, and any grading or excavation work
• The insurance section of your main contracts
• Drivers, subhaulers, current policy and loss runs

Frequently asked questions

Is cargo insurance required for dump trucks?

Not by federal law; the federal cargo requirement applies only to household goods carriers. Your contracts decide whether you need it.^[15]

Do I need a USDOT number if I only haul in-state?

Often yes. Washington and Texas, for example, require USDOT numbers for intrastate carriers.^[6][8]

Do I need a CDL to drive a dump truck?

A Class B CDL at 26,001 lb GVWR or more, and a Class A when towing a trailer over 10,000 lb with a combined rating of 26,001 lb or more. This applies to in-state driving too.^[1][2]

Do dump trucks have to be tarped?

It depends on the state. California and Washington allow 6 inches of freeboard instead of a cover, while Texas and Florida require the load to be covered or secured.^{[17][18][19][20]}

Why does the general contractor want additional insured status and a waiver of subrogation?

Additional insured status lets the contractor claim under your liability policy for your work. A waiver of subrogation stops your insurer from suing them to recover what it paid.^[13]
