OK CDL Combination Vehicles Marathon

Ready to put your new knowledge to the test? This Oklahoma CDL Combination Vehicles Marathon is a massive study tool that contains a compilation of all 133 questions that we have available for this OK endorsement. If you select a wrong 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”. Give it your best shot!

Perfect for

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