Based on official North Carolina exam questions

NC CDL General Knowledge Marathon

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

Got a couple of hours to spare? This North Carolina CDL General Knowledge Marathon is a monster of a study tool that contains all 693 questions from our database for this NC endorsement. If you give an incorrect 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”. Good luck!
