What to expect on the actual TN CDL exam

  • 50questions
  • 40correct answers to pass
  • 80%passing score

Ready for something a little tougher? This Tennessee CDL General Knowledge Marathon is a massive practice test that contains a mixture of all 346 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”. Delivers some serious studying power! Do your best to complete this mega test!
