ND CDL Combination Vehicles Practice Test 3 2025

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

If you’re looking to earn your Class A Commercial Driver’s License (CDL) in North Dakota, one of the requirements is passing the CDL Combination Vehicles Knowledge Test. You’ll need to study those sections of the North Dakota CDL Manual that discuss safe driving practices for combination vehicles, air brake systems and their maintenance, coupling and uncoupling procedures, skid and jackknife prevention, and inspections and vehicle components. The Combination Vehicles Knowledge Test includes 20 multiple-choice questions, and you must answer at least 16 correctly (80%) to pass.

If you fail on the first try, you must wait at least one business day before retesting, and an additional fee applies after three attempts. Our North Dakota CDL Combination Practice Tests are designed to help you pass the official exam on your first attempt! The practice tests mirror the format of the official exam to accustom you to its structure before you even enter the testing site. Our practice tests also include immediate feedback to help you learn as you go. This approach has proven more efficient than standard study guides and assessments that hold all feedback until the end. Once you’ve aced this one, check out another Combination Vehicles Practice Test here: https://driving-tests.org/north-dakota/nd-cdl-combination-test/.

In addition to passing this test, you must complete Entry-Level Driver Training (ELDT) with an FMCSA-approved provider. You must also pass the CDL General Knowledge Exam (we have practice tests for this as well!). Once you obtain your Commercial Learner’s Permit, you must hold it for a minimum of 14 days before scheduling your official hands-on Skills Test in a combination vehicle.

That’s quite a list of requirements; however, with your Class A CDL in hand, you can transport cargo in combination vehicles throughout the Peace Garden State and beyond. On I-29 running north to south and I-94 crossing east to west, you’ll find steady work in industries that rely on Class A CDL drivers. Energy, agriculture, manufacturing, and freight transport are some of the major ones, and employers such as FedEx Freight, Northern Plains Trucking, UPS, and Walmart Distribution Centers are always looking for combination-vehicle drivers.

You should also consider adding endorsements to your CDL, like Tanker (N), Hazardous Materials (H), and Doubles/Triples (T). Check out our Hazardous Materials Practice Tests here: https://driving-tests.org/north-dakota/nd-cdl-hazmat-practice-test/. Most combination vehicles use air brake systems, so you’ll want to pass the Air Brakes Test to remove any air-brake restrictions from your license.
