MA CDL Double/Triple Trailers Marathon
Original questions by our team Based on 2026 MA CDL Handbook
Need one final boost? This Massachusetts CDL Double/Triple Trailers Marathon is a new study tool that contains a mix of all 101 questions that we have available for this MA endorsement. If you give an incorrect answer, we’ll remember that question and will display it to you again at the very end of the Marathon 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!
