Driver and Motorcycle Learner's Permit
The knowledge exam (Learner's Permit Test) tests your knowledge of traffic laws, road signs, and driving safety rules. It determines whether you are prepared to operate a vehicle in accordance with DC law. The exam is offered on a walk-in basis at DMV service locations, and available in English, Spanish, Amharic, Chinese, French, Korean and Vietnamese. Telephone assisted exams are also provided for those who need help with their reading.

Commercial Driver's License (CDL)
An individual seeking to obtain a CDL must already have a regular driver's license prior to taking the CDL knowledge test. In order to receive a CDL, each applicant is required to take the appropriate CDL Knowledge tests for the CDL Class and/or endorsements they are applying for. CDL knowledge tests are offered on a walk-in basis at our Brentwood or Southwest Service Centers and are available in English only. Upon successful completion of the knowledge test(s), a CDL learner's permit will be issued in conjunction with your regular driver's license. The CDL learner's permit is valid up to one year and is non-renewable. Endorsements H (Hazardous Material), T (Tankers) S (School Bus) and X (Hazardous Material and Tankers) will not be displayed on the CDL learner's permit.

You may visit the DMV service location page to obtain information on service hours or the CDL office located at 1205 Brentwood Road, NE. to obtain a copy of the DC CDL Manual*. You may also download a DC CDL Manual* online.
