Test Instructions

  1. Download your state CDL manual and open up it up in another tab of your browser. Read it over, but you don’t need to try to memorize it!
  2. On this page, begin the first of our CDL practice tests in Classic Mode. See how well you do, but try not to stress out about any mistakes at this point.
  3. Next, switch to Practice Mode for intense preparation, complete with instant correct answers after every question and a CDL reference. 
  4. When you think you’re ready, take the exam! Each Exam Mode practice test is timed and you get your grade and results only after you’ve finished each test. This is very similar to the official state CDL written exams!
