DC CDL Hazardous Materials (HazMat) Marathon

Fasten your seat belt for one last wild ride of studying! This District of Columbia CDL Hazardous Materials (HazMat) Marathon is a monster of a practice test that contains a mix of all 192 questions that we have available for this DC endorsement. If you make a mistake, 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”. It might take some time, but you can do this!

Perfect for

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