AZ CDL Tanker Vehicles Marathon

Ready for something a little different? This Arizona CDL Tanker Vehicles Marathon is a monster of a study tool that contains a mixture of all 96 questions that we have available for this AZ 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 AZ CDL and CLP applicants
  • CDL holders adding endorsements
  • AZ CDL renewal applicants
AZ commercial driver's license
