How Does It Work?

Are you preparing to take your commercial driver’s license (CDL) knowledge test? Then now is the time to try a CDL practice test! After you've studied your state's CDL manual, another great way for you to prepare is to practice with tests that simulate your state's actual knowledge test. Just choose your state from the drop-down menu above, and you’ll be provided with an exam that is closely based on your state’s CDL manual, state and federal laws, and practice questions provided by the state if available.

How Is the CDL Practice Test Structured?

Our practice test has 50 multiple-choice questions, the same format you’ll find on your state’s CDL exam. These questions are phrased like the ones on your state’s knowledge test. Each question comes with a hint to help you choose the right answer. Each correct answer comes with an explanation that has been carefully written to help you become more familiar with the topic of the question. We want you to be able to answer questions on those topics correctly even if they are worded a bit differently. Please read each explanation; it is based on your state’s CDL manual and DMV/DOT website. Find your nearest DMV location.

Which Topics Are Covered?

This practice exam covers a wide range of topics that you’ll need to know about to pass your CDL knowledge test. These topics include aggressive drivers, braking techniques, cargo safety, distracted drivers, drunk driving laws, emergency preparedness, road and weather conditions, and safe backing.

No, we certainly did not forget about air brakes, combination vehicles, or hazardous materials! These topics are complex enough to deserve separate treatment. Just as states typically require you to pass specialized knowledge tests on those topics, we offer our own specialized practice tests on air brakes, combination vehicles, and hazardous materials.

How Many Times Should I Take the Practice Test?

We recommend that you keep taking the test until you become fully comfortable with the subject matter and receive a score high enough to boost your confidence about your upcoming CDL exam. A high score will bring you closer to passing your CDL knowledge test, so practice as many times as you’d like. There are no fees, and you won’t even have to register.
Good luck now and on your CDL test. Drive safely!

Cira R, WI

"I’m a retired vet and have been working as a fleet manager for a small company. I decided to get my CDL. I tried several online tests after fumbling through the study guide not knowing what to study. When I found these free tests I thought I was ready to test, but I failed several times. So I kept taking tests until I passed them all with only missing 4 or less on each. Well I tested today and passed the Class A the first time missing only 8 for all three test. This is the best out there!"
