Getting your commercial driver’s license (CDL) opens the door to a wide range of careers, from long-haul trucking to local delivery, such as our CDL jobs in Baltimore. But not every CDL is the same. Understanding CDL Class A vs Class B vs Class C is the first step to choosing the right license, because the class you hold decides which vehicles you can drive and which jobs you can take.
This guide to CDL Class A vs Class B vs Class C explains each class using Pennsylvania’s official definitions, shows how they compare side by side and helps you choose the one that fits your goals.
Quick answer: Class A covers combination vehicles like tractor-trailers. Class B covers heavy single vehicles like straight trucks and buses. Class C covers smaller vehicles carrying hazmat, 16 or more passengers or students. A Class A license also covers Class B and C vehicles, and a Class B license also covers Class C vehicles, with the right endorsements.
CDL Class A: Combination Vehicles
A Class A CDL is the license most people picture when they think of a professional truck driver, and it offers the most flexibility. It covers a combination vehicle with a gross vehicle weight rating (GVWR) of 26,001 pounds or more, as long as the vehicle being towed has a GVWR over 10,000 pounds.
With the right endorsements, a Class A CDL lets you operate:
- Tractor-trailers and semi-trucks
- Flatbed trucks
- Tank vehicles and double or triple trailers
- Livestock carriers and other combination vehicles
- All Class B and Class C vehicles
Because it covers everything else, Class A is the best choice if you want the most job options. If you are interested in CDL A truck driving jobs, this is the class to aim for.
Class B CDL: Heavy Straight Vehicles
A Class B CDL covers a single vehicle with a GVWR of 26,001 pounds or more, or any such vehicle towing a vehicle that is not over 10,000 pounds. You can drive Class C vehicles too, but you cannot drive Class A vehicles.
With the right endorsements, common Class B vehicles include:
- Straight trucks and box trucks
- Dump trucks and cement mixers
- Garbage trucks
- Delivery trucks
- Large buses, including city and school buses
Class B is a good fit if you want local routes and more time at home, and it is often quicker to train for than Class A.
Class C CDL: Smaller Specialty Vehicles
A Class C CDL covers a single vehicle with a GVWR under 26,001 pounds that is carrying hazardous materials requiring placards, is designed to carry 16 or more passengers including the driver, or is a school bus. Most Class C work is passenger transportation, so it is less common in freight trucking.
Common Class C vehicles include passenger vans, shuttle buses, small school buses and smaller trucks that haul placarded hazmat.

CDL Endorsements and Restrictions
An endorsement is an add-on to your CDL that lets you haul specialized loads or passengers. You earn one by passing an additional knowledge test, and some also require a skills test. PennDOT lists these common endorsements: H (hazardous materials), N (tank vehicles), X (hazmat and tank combined), P (passengers), S (school bus) and T (double and triple trailers).
TQM Logistics hires drivers with these endorsements:
- Tractor-trailers and semi-trucks
- Flatbed trucks
- Tank vehicles and double or triple trailers
- Livestock carriers and other combination vehicles
- All Class B and Class C vehicles
Restrictions limit what you can drive. For example, an E restriction means no manual-transmission vehicles and an L or Z restriction limits air brake vehicles, so test in the vehicle you intend to drive.
Entry-Level Driver Training (ELDT) by CDL Class
Since February 7, 2022, federal rules require entry-level driver training for anyone getting a Class A or Class B CDL for the first time, upgrading from Class B to Class A, or adding a hazmat, passenger or school bus endorsement for the first time. Training must come from a provider on FMCSA’s Training Provider Registry and includes theory and behind-the-wheel instruction. There is no minimum number of hours, but you must score at least 80% on the theory assessment.
Which CDL Class Should You Get?
- Choose Class A if you want maximum flexibility, long-haul or regional work and the widest range of employers.
- Choose Class B if you prefer local routes, delivery or construction work and want to be home more often.
- Choose Class C if your goal is passenger transport, such as shuttle or small school bus driving, or small hazmat vehicles.
If you are unsure, Class A gives you the most options because it also covers Class B and C vehicles. Age matters too. Most states let you apply at 18, but you are limited to driving within your state until you turn 21.
