Do you need a CDL for a roll-off truck?
Federal regulation sorts vehicles into three licensing groups by weight rating, and a straight roll-off truck normally lands in Group B, which is a Class B commercial driver’s license. The number that decides it is the gross vehicle weight rating printed on the manufacturer’s certification label, not what the box weighed on any given day.

The short answer, and the number it turns on
A straight roll-off truck is the textbook Group B case in the federal licensing groups, and Group B is a Class B commercial driver’s license. That is the answer most operators are looking for, and for a truck in ordinary roll-off service it is usually the right one.
The reason it is only usually is that the groups are defined by weight rating, not by body type. Nothing in the regulation mentions hoists, cables, rails or containers. It asks what the vehicle is rated to weigh, and it asks exactly the same question of a box truck, a dump truck and a roll-off truck.
So the short answer carries a condition. If the truck’s gross vehicle weight rating is 26,001 pounds or more, it sits in Group B. Read the rating before you assume the answer, because the rating is a fact about the truck rather than a fact about the trade.
The rest of this page is about how the groups are drawn, why the rating rather than the load is the deciding number, and which parts of the question a state agency answers instead of the federal regulation.
How the federal regulation groups vehicles
Section 383.91 of title 49 of the Code of Federal Regulations sets out three vehicle groups for commercial driver licensing. The groups below follow the regulation as published. They are the federal floor, and every state license is built on top of them.
Notice what the definitions consume. Two weight ratings, a towed-unit rating, a passenger count and a hazardous materials condition. There is no vocabulary in them for what the vehicle does for a living, which is why a body type never appears in the answer.
- Group A, Combination Vehicle: any combination of vehicles with a gross combination weight rating of 26,001 pounds or more, where the unit being towed is rated over 10,000 pounds.
- Group B, Heavy Straight Vehicle: any single vehicle with a gross vehicle weight rating of 26,001 pounds or more, or such a vehicle towing another vehicle not rated over 10,000 pounds.
- Group C, Small Vehicle: a vehicle qualifying as neither Group A nor Group B that carries 16 or more passengers including the driver, or that transports placarded hazardous materials.
- Step-down: a driver certified for Group A may operate Group B and Group C vehicles, and a driver certified for Group B may operate Group C vehicles, subject to the endorsements those vehicles require.
The step-down rule runs one way only
The step-down rule is worth reading twice, because operators regularly read it in both directions and it only works in one. A Group A certification reaches down over Group B and Group C. A Group B certification reaches down over Group C and no further.
That matters at the moment a roll-off business grows. A straight truck with a hoist is a single vehicle. A tractor pulling a trailer rated over 10,000 pounds is a combination, and a combination rated at 26,001 pounds or more is Group A. Adding a trailer to the yard can change the licensing group of the work, not just the equipment list.
The same logic runs the other way for light towing. A Group B vehicle towing a unit not rated over 10,000 pounds stays inside Group B by the regulation’s own words, which is why the towed unit’s rating is worth knowing before you hitch anything to the truck.
Why the certification label beats the scale ticket
The threshold in the regulation is a rating, and the rating lives on the manufacturer’s certification label, ordinarily on the driver’s door or the door jamb. It does not move. It reads the same on the day the truck runs empty to the yard as on the day it comes off a demolition job loaded to the springs.
Operators reason from load weight constantly, and it gets the question backwards in both directions. A truck rated at 33,000 pounds carrying an empty can is still a Group B vehicle for licensing purposes, because the rating did not change when the can came off. A truck rated below 26,001 pounds does not enter Group B because somebody overloaded it, though an overload has consequences of its own under the weight limits, which are a separate rulebook.
This is also why the answer travels with the truck rather than with the job, and why a general answer for the trade is a weaker answer than the label on the vehicle in front of you.
Read the certification label on the truck you actually drive before you rely on any general answer, including this one. We can describe how the regulation groups vehicles. We cannot tell you what your label says.
Endorsements sit on top of the group
The group answers which class of license, not which endorsements. The regulation’s step-down rule is expressly subject to the endorsements each vehicle requires, which makes the group the floor of the answer rather than the whole of it.
Which endorsements a particular roll-off operation needs follows how the truck is configured and what it carries. Group C exists in part for placarded hazardous materials, which is a useful reminder that cargo can move the licensing question independently of weight.
Federal driver licensing guidance is published by the Federal Motor Carrier Safety Administration. Its own licensing page refused our automated request when this page was researched, so the group definitions above are taken from the regulation itself, read through Cornell’s mirror of the Code of Federal Regulations, rather than from a summary. The regulation is the better source anyway.
The license is issued by a state, and the rest of the answer lives there
The federal groups are uniform across the country. The license itself is not issued federally. Applications, testing, medical paperwork and anything a state adds run through the state agency that issues driver licenses, and this page did not survey those state by state.
That distinction matters more in this trade than in most, because a roll-off operator can touch two unrelated state layers at once. The licensing layer decides who may drive the truck. A separate state layer, where one exists, decides whether the business may haul waste at all, and it is usually administered by an environmental or a utilities agency rather than by a licensing agency.
Pennsylvania is the clearest illustration that these are different questions with different answers. Its waste transporter authorization turns on registered gross vehicle weight thresholds of its own, set well below the licensing threshold above. Holding one has never meant holding the other.
Where to confirm your own position
Two calls settle almost every version of this question. The state agency that issues driver licenses answers which class you need and how to obtain it. The Federal Motor Carrier Safety Administration answers the federal side, including how the groups apply to an unusual configuration.
Bring three facts to either call: the gross vehicle weight rating from the certification label, the rating of anything you tow, and a plain description of what the truck carries. Those are the facts the group definitions actually consume, and a call that starts with them is short.
Nothing on this page is a determination about a specific driver, truck or business. It describes what the regulation says and names who decides.
What this guide does not settle
Each of these is a thing this page does not answer. They are listed rather than smoothed over, because a gap you can see is worth more than a sentence that reads as though there is none.
- Which endorsements a particular roll-off operation needs, which follows the truck’s configuration and its cargo. Ask the state agency that issues driver licenses, or the Federal Motor Carrier Safety Administration.
- Whether a given state adds licensing requirements above the federal groups. We did not survey state driver licensing rules for this page. Ask the agency that would issue your license.
- What the certification label on any particular truck reads. That is a fact about the vehicle, and only the label settles it.
Frequently asked questions
Is a roll-off truck a Class A or a Class B?
The regulation groups a single vehicle rated at 26,001 pounds or more as Group B, which is a Class B license. A straight roll-off truck is normally that case. A tractor pulling a trailer rated over 10,000 pounds, at a combination rating of 26,001 pounds or more, is Group A instead.
Does the load weight decide whether I need a CDL?
The threshold in the regulation is a weight rating, not a weighed load. The gross vehicle weight rating on the manufacturer’s certification label is the number the groups are drawn against, and it is the same whether the can is full or empty.
Can a Class B driver run a tractor and trailer?
The regulation’s step-down runs downward only: Group A covers Groups B and C, and Group B covers Group C, subject to endorsements. It does not run upward from B to A. Confirm your own position with the agency that issued your license.
