MN CDL Combination Vehicles Practice Test 3 2025

The Minnesota Combination Vehicles Knowledge Test includes 20 multiple-choice questions, covering critical topics such as safe operation of combination vehicles, air brakes and their use in tractor-trailers, preventing trailer skids and jackknives, coupling and uncoupling procedures, and inspection and maintenance requirements.

Passing this test, with its substantial amount of material, is one of several steps required to obtain a Class A Commercial Driver’s License (CDL). This particular class allows you to operate tractor-trailers or other large combination vehicles with a Gross Combination Weight Rating (GCWR) over 26,001 pounds, where the towed unit exceeds 10,000 pounds (Minnesota CDL Manual, Part A).

In addition to passing the CDL Combination Vehicles Test, you must also complete Entry-Level Driver Training (ELDT) through an FMCSA-approved training provider listed on the Training Provider Registry (TPR), pass the General CDL Knowledge Test, obtain a Commercial Learner’s Permit (CLP) and hold it for a minimum of 14 days, then pass the DVS Skills Test.

For the CDL Combination Vehicles Test, you must score at least 80% (16 correct answers) to pass. If you fail, you must wait one business day before retesting and may be required to pay a retest fee. Our Combination Vehicles Practice Tests provide immediate feedback after each response and also offer helpful hints when needed as you practice. Not only that, we have multiple practice tests to get you where you need to be to take the official test. Try another one here: https://driving-tests.org/minnesota/mn-cdl-combination-test/.

Nearly all combination vehicles use air brakes, making it vital to also pass the Air Brakes Knowledge Test to remove the “L” or “Z” restriction from your CDL. With that restriction in place, your Class A CDL is pretty useless, so make sure to check out our practice tests for this as well: https://driving-tests.org/minnesota/mn-cdl-air-brake-practice-test/. You can also enhance your career opportunities (and pay) by adding endorsements like the (T) Doubles/Triples, (N) Tank Vehicles, (H) Hazardous Materials, or (X) Tank and Hazmat combined.
