Driving a fully loaded semi-truck through the nation’s capital comes with its own set of challenges. Tour buses stop for photos, diplomatic motorcades appear without warning, and tourists step into the crosswalks without watching for approaching traffic. As a professional commercial driver, you must stay alert and exercise caution at all times. The Department of Motor Vehicles (DMV) employs a strict licensing process and requires all applicants to pass several exams.
If you are interested in driving combination vehicles, you must obtain a Class A CDL (Commercial Driver’s License). This type of license allows you to operate any combination vehicle with a gross combination weight rating (GCWR) of 26,001 pounds or more, as long as the towed unit weighs over 10,000 pounds.
The official general knowledge test is the first theory exam you must pass. It consists of 50 multiple-choice questions based on the official District of Columbia Commercial Driver License Manual (District of Columbia CDL Handbook). You must answer all questions and score 80% or higher to pass. Our Free District of Columbia CDL Permit Practice Test can help you prepare for this exam. It is available online and provides several features that will boost your learning potential.
