What is a Class B license (CDL)?

The CDL Class B license is one that allows you to drive any vehicle with a Gross Vehicle Weight Rating (GVWR) greater than 26,000 lbs, as well as any vehicle towing a trailer that does not exceed a GVWR of 10,000 lbs.

Holders of this type of license can operate with straight trucks, vans (such as delivery trucks), large buses (such as school, city and tour buses) and dump trucks with small trailers.

Keep in mind that each state has its own rules regarding the procedure for obtaining this type of driving license. Therefore, we recommend that you contact a local office of the Department of Motor Vehicles (DMV) for more detailed information on the Class B CDL licensing regulations in your state.

On the other hand, you should know that the tests that will be done to you are not easy and can be quite exhausting. And it is for this reason that preliminary training is essential.

NOTE: Drivers with this type of license can drive Class C but not Class A vehicles

Requirements for obtaining a Class B CDL License

One of the basic requirements for obtaining a CDL Class B license is the age of the applicant, which you must be at least 21 years old if you will drive in and out of your state. If you plan to drive only in your state, you can apply for a driver's license from the age of 18. Other than that, you must have a valid state driver's license. Drivers who have traffic violations on their driving record are strictly prohibited from applying for this license.

  • State-issued ID or other document proving legal presence in the United States
  • Proof of residence in the state where the application is made
