ID CDL General Knowledge Marathon

Ready for something a little tougher? This Idaho CDL General Knowledge Marathon is a gargantuan practice test that contains all 693 questions from our database for this ID endorsement. If you make a mistake, 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”. It might take some time, but you can do this!

Perfect for

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