View All PlansReady for something a little different? This Idaho CDL Combination Vehicles Marathon is a monster of a study tool that contains a mixture of all 133 questions that we have available for this ID endorsement. If you select a wrong 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”. Good luck!
