OK CDL Hazardous Materials (HazMat) Marathon

Ready for something a little different? This Oklahoma CDL Hazardous Materials (HazMat) Marathon is a lengthy practice test that contains a combination of all 192 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”. Delivers some serious studying power! Do your best to complete this mega test!

Perfect for

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