The CDL double/triple endorsement will permit you to operate vehicles with multiple trailers. To pass the exam, you will need to be knowledgeable in driver safety, uncoupling and coupling hauls, traffic laws, and emergency protocols. If you want to preview the exam before you take it, take our Free Colorado CDL Double/Triple Trailers Practice Test! Using the official Colorado CDL Handbook we created a 20-question test that matches the content areas and format of the actual DMV exam. You can test your knowledge before having to register for the real thing! We require an 80% passing score but we do provide you with correct responses and explanations if you miss some questions.

No one wants to have to go to the DMV more than once to take the same endorsement exam. Try our Free Colorado CDL Double/Triple Trailers Practice Test and ensure that you pass the exam on the first attempt!
