To become a licensed commercial driver in the capital of the United States, you must meet the eligibility requirements. These requirements are in place to ensure that every driver who earns a Commercial Driver’s License (CDL) can operate such vehicles safely and responsibly. While the minimum age to begin the licensing process is 18, you must be 21 to drive commercially out of the District, carry passengers, or haul hazardous materials. The path to a Commercial Learner’s Permit (CLP) begins with understanding pre-trip inspections, loading and unloading procedures, and safe driving practices.
As you begin your learning phase, the official District of Columbia Commercial Driver License Manual (District of Columbia CDL Handbook) will be your primary study resource. This handbook will teach you everything you need to know to pass the official general knowledge exam. To increase your chances of achieving a passing score on your first attempt, consider incorporating our practice tests into your study routine. They enable active learning, which helps you remember and recall important details.
