DE CDL Double/Triple Trailers Marathon

What to expect on the actual DE CDL exam

  • 20questions
  • 16correct answers to pass
  • 80%passing score

Need one final boost? This Delaware CDL Double/Triple Trailers Marathon is a monster of a study tool that contains a mix of all 101 questions that we have available for this DE 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!
