FREE OK CDL Tanker Vehicles Marathon 2019
Ready for something a little tougher? This Oklahoma CDL Tanker Vehicles Marathon is a new practice test that contains a compilation of all 61 questions that we have available for this OK 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!
