Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements. Welcome to our fourth Michigan CDL Combination Vehicles Practice Test! Updated for December 2025, this intuitive tool can significantly boost your learning potential. It closely reflects the content and format of the official combination vehicles knowledge test, which you must pass to get your CLP (Commercial Learner’s Permit). All questions are based on Section 6 (Combination Vehicles) of the official Commercial Driver’s License Manual (Michigan CDL Handbook 2025). We recommend reading this manual multiple times during your learning phase, focusing especially on the sections relevant to your profession.
You will learn combination vehicle safety practices, weight distribution, air brake systems in combination vehicles, and how to perform thorough inspections before and after trips. This practice test can be used to evaluate your knowledge before exam day. If you are unfamiliar with this subject, you can also use this tool for learning. Each question includes a detailed explanation that helps you understand the meanings behind the correct answers.
Additionally, you can request further explanations, real-life examples, and helpful insight from “Officer Frank,” your automated assistant. Customize your learning experience with the features available in the test settings menu. You can access this menu by clicking the three dots in the top-right corner of the page. Since this practice test is available in multiple languages, you can also select yours from the test settings menu.
Begin your training today and dedicate the following weeks to your learning phase. During this time, you must put in the time and effort to master commercial driving theory. While our combination vehicles practice tests will teach you how to safely operate combination vehicles, our Free Michigan CDL Permit Practice Test can help you pass the official general knowledge exam.
You get unlimited attempts and 24/7 browser-based access to our practice tests. Train anytime, anywhere in the world, as often as your schedule allows. Within a few weeks, you’ll be ready to take your theory exams and achieve a passing score on your first attempt.
