CT CDL General Knowledge Marathon

Got a couple of hours to spare? This Connecticut CDL General Knowledge Marathon is a massive practice test that contains all 693 questions from our database for this CT 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 and renewal CDL/CLP applicants, and those adding endorsements
