MI CDL Combination Vehicles Practice Test 3 2025

As you can probably imagine, there are several steps that must be taken in order to obtain a Class A Commercial Driver’s License (CDL). A Class A license is required to legally operate combination vehicles, such as tractor-trailers, in Michigan. For any combination of vehicles with a Gross Combination Weight Rating (GCWR) of 26,001 pounds or more, provided the towed vehicle’s Gross Vehicle Weight Rating (GVWR) exceeds 10,000 pounds, you must hold this license. The official requirements and procedures are outlined in the Michigan Commercial Driver License Manual issued by the Michigan DOS.

Before earning your Class A CDL, the steps mentioned earlier include the completion of Entry-Level Driver Training (ELDT) through an FMCSA-approved provider, passing the CDL General Knowledge Test, obtaining and holding the CLP for a minimum of 14 days, passing the behind-the-wheel Skills Test, and passing the Combination Vehicles Knowledge Test. The Combination Vehicles Knowledge Test includes 20 multiple-choice questions, and you must score at least 80% (16 correct) to pass. If you do not pass, the DOS requires a minimum one-business-day waiting period before retesting, and a fee applies for each attempt. This potential for delays and added fees is completely avoidable by using our expert-crafted practice tests, designed to help ensure you pass the official test on your first attempt!

Our Free Michigan CDL Combination Practice Tests replicate the structure of the official exam. They draw directly from the latest Michigan CDL Manual, which is the primary source for the official test. Our practice tests provide immediate feedback to improve recall and speed the learning process. Practice topics include safe driving practices for combination vehicles, preventing trailer skids and jackknives, air-brake systems in combination vehicles, coupling and uncoupling procedures, and inspection protocols. Also, we have not one but several in our series of state-specific practice tests. Try another one here: https://driving-tests.org/michigan/mi-cdl-combination-test/.

Obtaining your Michigan Class A CDL opens doors across multiple industries, from automotive manufacturing and logistics to agriculture, forestry, and construction. Major roadways like I-75, I-69, I-96, and US-23 link major Michigan industries to the rest of the U.S. and Canada. Because of the richness of this opportunity, the Class A CDL can be a very lucrative advance in your driving career!

Because most tractor-trailers use air brakes, we encourage you to prepare for the Air Brakes Knowledge Test to remove the “L” restriction from your CDL: https://driving-tests.org/michigan/mi-cdl-air-brake-practice-test/.
