Ready for something really challenging? This Colorado CDL Double/Triple Trailers Marathon is a super-challenging practice test that contains a mix of all 101 questions that we have available for this CO endorsement. If you select a wrong 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”. Delivers some serious studying power! Do your best to complete this mega test!
