MO CDL Tanker Vehicles Marathon

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

Got a couple of hours to spare? This Missouri CDL Tanker Vehicles Marathon is a new practice test that contains a combination of all 96 questions that we have available for this MO endorsement. If you make a mistake, 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!
