Pre-Trip Inspection CDL Practice Tests

Our Free Online Pre-Trip Inspection Practice Test questions and answers will prepare you online to Prepare for the Pre-Trip portion of the CDL skills test. Each test has 3 testing modes to help you prepare and easily remember the information.

  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!

Note: For more information, see our guide on How to Pass the Official State CDL Exams.
