Do you need a CDL to drive a dump truck?

Dump trucks range from one-ton pickups with a dump body to tri-axles hauling 18 tons of gravel, and the license you need changes a lot across that range. If you’re starting a hauling business, adding a truck to a landscaping crew or buying your first dump truck at auction, knowing the license rules before you buy decides who can drive it and how quickly you can put it to work. This guide explains when a dump truck needs a CDL, which trucks you can drive without one, and when you need a Class A instead of a Class B.

The short answer: in the U.S., you need a CDL to drive a dump truck with a gross vehicle weight rating (GVWR) of 26,001 lbs or more, which covers most single-axle, tandem and tri-axle dump trucks. Those trucks need a Class B CDL. Smaller dump trucks rated at 26,000 lbs or less, like Ford F-550s, Isuzu NRRs and medium-duty trucks built at 26,000 lbs, can be driven with a regular license. If you pull a trailer rated over 10,000 lbs and the combination is rated at 26,001 lbs or more, you need a Class A.

Dump truck CDL requirements by truck size

Dump truck type	Typical GVWR	License needed (U.S.)
One-ton and Class 4 to 5 dump trucks (Ford F-450/F-550, Ram 4500/5500, Chevrolet Silverado 4500HD/5500HD)	14,000 to 19,500 lbs	Regular license
Class 6 medium-duty dump trucks (Isuzu NRR, Hino 195, trucks built at 26,000 lbs)	Up to 26,000 lbs	Regular license
Single-axle dump trucks	26,001 to about 35,000 lbs	Class B CDL
Tandem-axle dump trucks	About 46,000 to 66,000 lbs	Class B CDL
Tri-axle dump trucks	About 60,000 to 75,000 lbs	Class B CDL
Any dump truck towing a pup, transfer or equipment trailer rated over 10,000 lbs, with a combined rating of 26,001 lbs or more	Varies	Class A CDL

GVWR ranges vary by manufacturer and build. Always check the rating on the certification label in the driver’s door jamb, not the listing.

What is the largest dump truck you can drive without a CDL?

The largest dump truck you can drive without a CDL is a straight truck with a GVWR of 26,000 lbs or less.

Several manufacturers build medium-duty trucks rated at exactly 26,000 lbs for this reason, so contractors can hire drivers without a CDL. These trucks typically carry around 5 to 6 cubic yards of material, depending on the body and the material’s weight. Remember that GVWR includes the truck itself, so a heavy dump body and plow leave less room for payload. Our GVWR guide explains how to work out what a truck can really carry.

Do you need a CDL for a non-CDL dump truck with a trailer?

No, as long as the trailer is rated at 10,000 lbs or less, a dump truck rated at 26,000 lbs or less doesn’t need a CDL, even if the combination weighs more than 26,000 lbs.

A Class A CDL is only required when the combination is rated at 26,001 lbs or more and the trailer itself is rated over 10,000 lbs. That makes the trailer’s GVWR the number to check before you hitch up an equipment trailer to haul a skid steer or mini excavator. Our guide to the best dump trailers covers how trailer ratings affect licensing.

Do you need a CDL for a dump truck with air brakes?

Air brakes alone don’t require a CDL under federal rules, but if you have a CDL, you need to pass the air brake test to drive trucks with air brakes.

Most heavy dump trucks have air brakes, so CDL drivers who test in a truck without them get an “L” restriction on their license that bars them from driving air brake vehicles. If you’re hiring drivers for a tandem or tri-axle, check for this restriction.

When are dump truck drivers exempt from a CDL?

Federal rules exempt a few groups, including farmers, firefighters and military drivers.

• Farmers. Farmers driving their own farm vehicles to haul their own products or supplies within 150 miles of the farm, and not for hire, can be exempt, depending on the state.
• Emergency and military vehicles. Firefighters, emergency operators and military drivers are exempt.
• Off-road use. CDL rules apply to public roads. Off-highway trucks used only on a private job site aren’t covered, although they still need to be hauled between sites.

Rules for municipal and snowplow drivers vary by state, so check with your state DMV.

Do you need a DOT number for a non-CDL dump truck?

Often yes, because DOT rules start at 10,001 lbs GVWR, well below the CDL threshold.

A non-CDL dump truck used for business across state lines usually needs a USDOT number, and its drivers need a DOT medical card, even though they don’t need a CDL. Many states apply similar rules to trucks that never leave the state. Our DOT number guide explains who needs one.

Do you need a special license for a dump truck in Canada?

Yes, most heavy dump trucks in Canada need a commercial licence class, and the class depends on your province.

For example, heavy straight trucks generally need a Class 3 licence in Alberta and British Columbia and a Class D licence in Ontario, while dump trucks pulling heavy trailers need a Class 1 or Class AZ. Weight and axle thresholds differ between provinces, so check with your provincial licensing office before you buy.

How do you get a CDL to drive a dump truck?

Most dump truck drivers need a Class B CDL, which requires a commercial learner’s permit, entry-level driver training from a registered provider, and a skills test.

If you’ll pull a pup or transfer trailer, get a Class A instead, since it also covers Class B trucks. Our guide to understanding CDLs covers license classes, endorsements, training costs and timelines.

Should you buy a CDL or non-CDL dump truck?

Buy a non-CDL dump truck if you haul smaller loads and want any crew member to drive it, and a CDL truck if you haul heavy material all day.

A 26,000 lb truck keeps your hiring options open and costs less to buy and run, which suits landscaping, junk removal and small construction jobs. Tandem and tri-axle trucks carry two to three times as much per trip, which matters for aggregate hauling and excavation. Our guide to dump truck hauling capacity shows how to match truck size to your loader or excavator.

The bottom line

If a dump truck is rated at 26,001 lbs or more, you need a Class B CDL, and if you tow a trailer rated over 10,000 lbs with a combined rating of 26,001 lbs or more, you need a Class A. Dump trucks rated at 26,000 lbs or less can be driven with a regular license. Check the door jamb label before you bid, use our inspection checklist to check the truck, and factor in the buyer’s premium when you set your budget. Browse used dump trucks on RB Auction.
