DC CDL General Knowledge Marathon

Ready for something a little different? This District of Columbia CDL General Knowledge Marathon is a super-challenging practice test that contains all 693 questions from our database for this DC 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”. Delivers some serious studying power! Do your best to complete this mega test!

Perfect for

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