Free Florida CDL Permit Practice Test: General Knowledge 2026

To obtain a Commercial Driver’s License (CDL) in Florida, there is a series of requirements you must meet. There are three classes of CDLs. A Class A CDL allows you to operate combination vehicles with a Gross Combination Weight Rating (GCWR) of 26,001 pounds or more in which the towed vehicle weighs more than 10,000 pounds. This is the class of CDL you must get to drive semi-trucks or tractor-trailers. A Class B CDL allows you to operate a single vehicle with a Gross Vehicle Weight Rating (GVWR) of 26,001 pounds or more, or to tow a vehicle that does not exceed 10,000 pounds. This license is suitable for large buses and straight trucks, including most dump trucks. A Class C CDL allows you to operate relatively smaller vehicles designed to transport hazardous materials or 16 or more occupants (including the driver). Decide which class of CDL you want to apply for, based on the types of vehicles you expect to be driving in your career.

Before you can obtain a CDL, you must become proficient in commercial driving. To practice commercial driving (under supervision), you must obtain a Commercial Learner’s Permit (CLP). And for that, you must submit to a medical examination and pass the official General Knowledge written test. That’s where we come in.

The official Florida Commercial Driver License Manual contains all the information covered by the questions on the official knowledge test. But it’s written like a reference work, not like a textbook to facilitate self-study. One better study tool is our set of General Knowledge practice tests like this one. The structure and content of this free Florida CDL permit practice test are similar to those of the official test. It’s also up to date as of April, 2026. On this practice test, you’ll find 20 questions on such topics as backing, driving on downgrades, cargo management, driving emergencies, stopping distance, and Florida driving laws. But unlike the official test, each of our practice questions includes a helpful hint and an explanation of the correct answer.

So, what is driving in Florida like? If you’ve lived there for some time, you probably already have an idea. It can be gorgeous in much of the state, the winter envy of Northerners battling frigid winds, blizzards, and Nor’easters. Florida is the only continental US state with a tropical climate (south of Lake Okeechobee). But with that climate can come heavy rainstorms and thunderstorms, and even hurricanes (especially from August to October).

Test-taking tip: Read all answer choices carefully before you select one. One or more answers may seem plausible – but you must select the best or most complete answer.
