View All PlansWelcome to our second North Dakota CDL Combination Vehicles Practice Test! Consisting of 25 multiple-choice questions, this intuitive tool closely reflects the content and format of the official combination vehicles knowledge test. You must answer all questions and score 80% or higher to pass, leaving little room for error. However, beginners should ignore their score during their first few attempts.
Your knowledge can only be improved gradually. Each mistake you make is an opportunity to learn. We provide a detailed explanation for each question, helping you understand the reasoning behind the correct answer. Please pay attention to this feedback and note it in a notebook or notebook app for future reference. To reflect the latest updates brought by DOT rules or state law, we frequently update this practice test (most recently for November 2025). The official ND DOT website provides the most up-to-date information, so you should check it regularly.
