The official knowledge test requires you to answer at least 80% of its 20 questions to pass. The instruction provided by the practice test makes this score achievable. You’ll be confident in the training that the practice test provides to put your stress aside and meet the challenges of the official knowledge test.

This Colorado DMV Double/Triple Trailer endorsement practice test is supported by authoritative information to validate the information you must learn. The practice test is based on the most recent Colorado DMV CDL manual (Colorado CDL Handbook 2025) and is up to date as of October 2025. It contains 20 multiple-choice questions, resembling those on the official knowledge test, to identify the information you must better understand. Unlike using a study guide that trains you to memorize the answers to a series of questions, you won’t find yourself at risk of being stuck in your progress or lost in confusion. The practice test interacts with your responses and provides a detailed explanation of how to correct any incorrect answers. You can completely trust the information offered because it is taken directly from the Colorado CDL manual and can be appropriately applied to various driving scenarios. Additionally, you will find this information easily understandable, making it possible to pass the official knowledge test on your first attempt.
