If you’re aiming to operate combination vehicles in the Commonwealth of Pennsylvania, you’re about to join the ranks of those who keep freight, food, and fuel moving across the Keystone State. To do it legally, you’ll need a Class A Commercial Driver’s License (CDL), which means passing the Combination Vehicles Knowledge Test (and completing several other requirements) before you hit the open road. Our Pennsylvania CDL Combination Vehicles Practice Tests are the perfect tool to speed your learning process and help ensure you pass the official DOT test on your first attempt!
In addition to passing the official Combination Vehicles Test, you must complete Entry-Level Driver Training (ELDT) through an FMCSA-approved provider. You’ll also need to pass the CDL General Knowledge Test, obtain a Commercial Learner’s Permit (CLP), hold it for a minimum of 14 days, and then pass a behind-the-wheel Skills Test. There is quite a bit to get done prior to licensure, but we promise, it’s well worth the effort.
The Combination Vehicles Knowledge Test includes 20 multiple-choice questions, and you’ll need to answer at least 16 correctly (80%) to pass. If you don’t pass on the first try, the DOT requires a minimum one-business-day wait before retesting, and a test fee applies for each new attempt. Our practice tests are your key to avoiding those hassles.

Our Pennsylvania CDL Combination Practice Tests take the stress out of studying. They mirror the official DOT test and are based on its primary resource, the Pennsylvania Commercial Driver’s Manual. Our practice tests utilize proven learning techniques, such as instant feedback and hints as you go, to help you retain what you study. Covered topics include safe driving techniques for combination vehicles, preventing jackknives and trailer skids, coupling and uncoupling procedures, air brake systems for combination vehicles, and vehicle inspection and maintenance requirements.

Earning your Class A CDL opens doors across major industries, including logistics, agriculture, energy, food distribution, and manufacturing. The state’s major roadways, including I-76, I-78, I-81, and I-95, provide the infrastructure needed to support many major employers who rely on Class A-licensed drivers.
Most combination vehicles use air brakes, and removing that restriction from your license is a necessity to flourish in this industry. Use our Air Brakes Practice Tests to pass the Air Brakes knowledge test on the first try: https://driving-tests.org/pennsylvania/pa-cdl-air-brake-practice-test/.
Finally, consider earning endorsements to expand your opportunities, such as (N) Tank Vehicle, (H) Hazardous Materials, (T) Doubles/Triples, (P) Passenger Vehicles, or (S) School Bus. Check out one of our practice tests here: https://driving-tests.org/pennsylvania/pa-cdl-hazmat-practice-test/.
