Ready to put your new knowledge to the test? This Tennessee CDL Pre-Trip Inspection Marathon is a new practice test that contains a combination of all 60 questions that we have available for this TN endorsement. If you give an incorrect answer, we’ll remember that question and will display it to you again at the end of the exam until you’ve answered that question correctly. In other words, the Marathon will cycle through your missed questions until you answer each one correctly. You must make a 100% to pass. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. Good luck!
