Which CDL is better for drivers?


1. What is a CDL Class A?

Overall, CDL class A is the most common type of CDL. In most states, obtaining a CDL Class A allows truck drivers to operate any vehicle with a semi-trailer or trailer with two or more axles. They have the most latitude of any business driver’s license. There are no limitations on the number of vehicles you can tow as long as the GVWR (Gross Vehicle Weight Rating) of the towing vehicle is at least 10,000 pounds greater than the GCWR of the towed vehicle.

To successfully obtain the class A CDL, you should pass the following tests below:

  • General Knowledge Test
  • Air Brakes
  • Combination Vehicle 
  • Pre-Trip Inspection

In order to pass those tests, we strongly suggest you take a look at the CDL General Knowledge Test Study Guide, CDL Air Brakes Test Study Guide as well as the Combination Test Study Guide thoroughly to understand the test format and knowledge area you should know.


2. What is a Class B CDL?

A Class B CDL authorizes the operation of a single vehicle with a gross weight of more than 26,000 pounds but no more than 10,000 pounds of towing capability. With a Class B license, you can operate buses, trash trucks, delivery trucks, dump trucks, and other vehicles.

For a Class B CDL license, you will have to pass the General Knowledge test, Basic skills test, Air-brakes test, Pre-trip inspection, and any other applicable exams.

Read the CDL Pre-trip Inspection Study Guide to understand and get the instruction in order to score high on the real test.

3. What is the difference between CDL class A vs CDL class B?


3.1. Driver age

In general, you are allowed to obtain a class B license if you are 18 years old.  Additionally, a class B holder only can operate the vehicle on the borderline of your state. On the other hand, you must be at least 21 years old to apply for CDL class A. Furthermore, if you have the right endorsements, you are also allowed to operate class B vehicles as well. To compare, a class A CDL is known as the “universal” CDL since it allows you to drive a variety of commercial vehicles and tractor trailers. A class B CDL also enables the operation of other types of vehicles, such as straight trucks and dump trucks, although it is more restricted than a class A CDL.

3.2. Allowed vehicles

The distinctions between CDL class A vs class B are related to the types of vehicles and their weight, notably the load that the trucks will be hauling. 

Obtaining a CDL Class A allows you to operate a combination of vehicles with a gross vehicle weight rating (GVWR) of 26,001 pounds or more.  It also allows you to tow a trailer weighing 10,000 pounds or more. Each endorsement can allow you to haul different types of cargo, such as hazardous materials or tankers. Vehicles that may be driven with a Class A include:

  • A tractor-trailer often referred to as a semi, big rig, or 18-wheeler
  • Trucks and trailers combinations, including double and triple trailers
  • Buses on tractor trailers
  • Tanker vehicles
  • Vehicles with flatbeds
  • Depending on endorsement criteria, most Class B and Class C vehicles

A CDL Class B allows you to operate a single vehicle weighing 26,001 pounds or more without the need of a trailer. It also enables you to pull a trailer weighing less than 10,000 pounds with any vehicle. Vehicles that may be driven with a Class B include:

  • Straight trucks
  • Large buses, such as city buses, tourist buses, and school buses
  • Buses with segments
  • Box trucks, including delivery trucks and furniture trucks
  • Small trailer dump trucks
  • Some Class C vehicles that have the appropriate endorsements

To compare CDL Class A vs class B, you can look at the table we listed below:

Categories Class A Class B
Weight of truck ≥  26,001 pounds ≥  26,001 pounds
Weight of trailer ≥ 10,000 pounds ≤ 10,000 pounds


3.3. Career options

By the same token, a CDL Class A has several advantages in addition to being necessary for driving a large truck. Typically, there are more positions available that need Class A drivers than Class B.

However, because there are fewer Class B jobs available, the market is extremely competitive. Drivers may choose a CDL Class B in the following situations:

  • The driver has a specific job that only requires a Class B vehicle.
  • Trucking is viewed as temporary work before transitioning to a more permanent one.
  • The driver prefers to work in a relatively confined geographic region, such as a single metro area or state.

4. What are the suggested CDL jobs for both class A and class B?

Surprisingly, you may pursue a variety of occupations with your CDL Class A vs class B.

4.3. Dispatcher

Aside from truck driving employment, there are numerous career alternatives to explore if you are seeking CDL driver jobs. Dispatchers use radio communication to connect with truck drivers. Most of the time, they transmit crucial trip information to the driver. They are sometimes in charge of overseeing many drivers.

They are also responsible for tracking equipment and vehicles while they are on the road. Dispatchers often serve as liaisons between the carrier and the truck driver.
