View All PlansWelcome to our second New Hampshire CDL Combination Vehicles Practice Test! This intuitive tool has been specifically designed to help you study efficiently and pass the official combination vehicles knowledge test on your first attempt. Use it regularly throughout your learning phase to build a strong foundation for your driving skills. This practice test features 25 multiple-choice questions based on Section 6 (Combination Vehicles) of the official New Hampshire Commercial Driver’s License Manual (New Hampshire CDL Handbook 2025). To pass, you must score 80% or higher, just like on the official exam.
Your personal Challenge Bank™ automatically stores every question you answer incorrectly. Instead of repeating questions you’ve already mastered, you can focus on the areas that need improvement. Each stored question includes a detailed explanation that helps you understand the reasoning behind the correct answer. This approach helps you learn from your mistakes and avoid repeating them on exam day. Visit your Challenge Bank at the end of your study sessions and eliminate all stored questions by answering them correctly.
This practice test has been recently updated for November 2025. You’re practicing with the latest version available, which means you won’t waste time on outdated information that no longer appears on the official combination vehicles knowledge exam. However, we recommend checking the official NH DMV website for the most recent updates.
As you progress through your learning phase, please pay special attention to pre-trip inspections. They are critical for the safe operation of combination vehicles. The official general knowledge exam will evaluate your understanding of commercial driving theory, including pre-trip inspections. You can find more information on this topic in the official Commercial Driver’s License Manual, but you can also train with our Free New Hampshire CDL Permit Practice Test.
Becoming a safe and responsible commercial driver takes time and effort. Don’t rush through your learning journey or try to memorize answers without understanding their meaning. Use our practice tests regularly to build your knowledge and develop the confidence you need to ace your theory exams on exam day.
