OK CDL Double/Triple Trailers Marathon

Ready for one final challenge? This Oklahoma CDL Double/Triple Trailers Marathon is a super-challenging practice test that contains a mixture of all 101 questions that we have available for this OK 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!

Perfect for

  • First-time OK CDL and CLP applicants
  • CDL holders adding endorsements
  • OK CDL renewal applicants
OK commercial driver's license
