There are three classes of Commercial Driver’s Licenses (CDLs). A Class A CDL allows you to operate combination vehicles with a gross combination weight rating (GCWR) of 26,001 pounds or more, provided the towed vehicle(s) has a gross vehicle weight rating (GVWR) of more than 10,000 pounds. This class of CDL is generally for operating semi-trucks and tractor-trailers, including flatbed semi-trucks. A Class B CDL allows you to operate a single vehicle with a GVWR of 26,001 pounds or more or a combination of vehicles where the towed vehicle has a GVWR of 10,000 pounds or less. This class of CDL is generally for large buses and straight trucks, including box trucks and most dump trucks. A Class C CDL is for other kinds of commercial vehicles that transport hazardous materials or at least 16 occupants (including the driver). This class of CDL is generally for small buses (including shuttle buses) or small trucks carrying hazardous materials.
No matter which class of CDL you want, you must meet a series of requirements. Notably, you must pass an official skills test, which includes basic vehicle maneuvers, a pre-trip inspection test, and a road test. To pass this test, you must practice commercial driving under supervision until you’re good enough to drive unsupervised. To be allowed to practice commercial driving, you’ll need a Commercial Learner’s Permit (CLP).

To obtain a CLP, you must meet certain requirements too, including passing the official General Knowledge test on the basic theory of commercial driving. The questions on this knowledge test are based on the official Kentucky Commercial Driver License Manual (Kentucky CDL Handbook 2026). However, if you’ve had trouble memorizing information contained in this manual, we can help.
This free Kentucky CDL permit practice test you’re about to take is based on the official CDL manual, just like the official knowledge test. It’s up to date as of January, 2026. There are 50 multiple-choice practice questions on such topics as basic maneuvers, emergency preparedness, and pre-trip inspections. If you get stuck on a question, use the available hint. If you still miss a question, read the explanation of the correct answer carefully so you’ll know what to answer the next time. You can also ask our automated assistant for even more help. With us, there’s no time limit; take all the time you need to learn and master the material covered by this practice test. You can even use the practice test as an open-book exam: Keep the official CDL manual open at the same time. You’ll learn more by looking up the correct answer to a puzzling question instead of just guessing the answer.
