To operate combination vehicles legally in Pennsylvania, you must obtain your Class A Commercial Driver’s License (CDL). This process involves passing the Combination Vehicles Knowledge Test and meeting several other requirements. Before you can even schedule your required hands-on CDL skills test, you must complete Entry-Level Driver Training (ELDT) through a provider approved by the Federal Motor Carrier Safety Administration (FMCSA).
The Pennsylvania Combination Vehicles Knowledge Test consists of 20 multiple-choice questions. You must answer at least 16 correctly (80%) to pass. If you fail, PennDOT requires you to wait at least one business day before retesting, and a test fee will be required for each attempt.
Our Pennsylvania CDL Combination Vehicles Practice Tests go well beyond traditional study guides offered by other online providers. Our methodology has been scientifically proven to speed learning and increase retention by closely mirroring the real exam and providing immediate feedback on responses and hints to help if you get stuck. Our practice tests are based on the most recent Commonwealth of Pennsylvania Commercial Driver’s Manual and are designed to ensure first-time success. Covered topics include safe driving techniques for combination vehicles, prevention of trailer skids and jackknifing, coupling and uncoupling procedures, air brake systems specific to combination vehicles, and inspection requirements.
Earning your Class A CDL greatly enhances your employment prospects across Pennsylvania. The state’s major industries include logistics, agriculture, energy, food distribution, and manufacturing. All of these rely on skilled CDL drivers. High-traffic highways like I-76 (the Pennsylvania Turnpike), I-81, I-78, and I-95 are major arteries for goods (and passengers) transported across the Mid-Atlantic, Northeast, and Midwest regions.
Additionally, if you haven’t removed the air brake restriction from your license, now is the time. Nearly all combination vehicles in Pennsylvania use air brakes. Be sure to check out our Air Brakes Practice Tests to help you pass that knowledge test on your first attempt.
We also encourage you to pursue endorsements such as (N) Tank Vehicle, (H) Hazardous Materials, (T) Doubles/Triples, and (P) for public transit and school bus driving opportunities. Each expands your career options, and we also offer practice tests for those endorsements. We are your one-stop shop for all CDL testing needs!
