2025 Florida | Frequently Asked Questions
In Florida, a Commercial Driver's License (CDL) Class B is a type of license required to operate vehicles with a Gross Vehicle Weight Rating (GVWR) of more than 26,000 pounds. It also allows the holder to tow vehicles that weigh less than 10,000 pounds. This includes buses, dump trucks, delivery trucks, and straight trucks.
A Class B CDL license in Florida allows the holder to operate single vehicles with a Gross Vehicle Weight Rating (GVWR) of 26,001 pounds or more, or any such vehicle towing another not in excess of 10,000 pounds. This includes vehicles like city buses, tourist buses, segmented buses, delivery trucks, dump trucks, and utility trucks.
To acquire a Class B CDL license in Florida, an applicant must be at least 18 years old (21 for interstate driving), possess a valid Florida driver's license, pass a vision test, and successfully complete the General Knowledge test. Additionally, an applicant must pass the pre-trip, basic controls and road test for the desired vehicle. A medical examination report is also required.

Specific endorsements are not necessary for a Class B CDL license, but they can broaden your driving capabilities. Endorsements allow you to drive certain types of vehicles or transport specific goods. For example, a passenger or school bus endorsement allows you to drive large buses, while a hazardous materials endorsement allows you to transport hazardous materials.
The Class B CDL skills assessment in Florida includes three parts: a pre-trip inspection, a basic vehicle control test, and an on-road driving test. The pre-trip inspection tests your knowledge on vehicle safety, the basic vehicle control test checks your ability to maneuver the vehicle, and the on-road driving test assesses your practical driving skills in various traffic situations.

In Florida, the written Class B CDL test is primarily offered in English. However, some locations may provide the test in Spanish.
