How the District of Columbia DMV permit test works

The District of Columbia knowledge test is a multiple-choice exam based on the official DMV handbook, the DC DMV Automobile Driver Manual.

Taken at a DC DMV service center, or virtually by appointment for the standard and GRAD (ages 16–20) tests; the learner permit test allows 75 minutes.

Wait three full calendar days after a failed test. After six failures within 12 months, you cannot test again until 12 months after the first failure.

Offered in 24 languages, including English, Spanish, French, Amharic, Arabic, Chinese, Korean and Vietnamese.

District of Columbia learner's permit requirements

In District of Columbia you can apply for a learner's permit at 16. Applicants under 18 usually need a parent or guardian's consent.

Before the road test, teen drivers must hold the permit for at least 6 months. Supervised driving required: 40 hours with a licensed driver 21 or older before the provisional license, then 10 hours of night driving before the full license with conditions (teens).

Proof of identity and date of birth (such as a birth certificate or passport).
Your Social Security number, if you have one.
Proof of District of Columbia residency.
A vision screening and the knowledge test.

The DMV publishes the exact document list: check it before your appointment, especially if you want a REAL ID-compliant card.

District of Columbia graduated driver licensing (GDL)

After the learner stage and the road test, teens can get a provisional (intermediate) license from age 16½.

Provisional drivers may drive 6 a.m. to 10:59 p.m. Sunday–Thursday and until 11:59 p.m. Friday–Saturday (until 11:59 p.m. every day in July and August). Under-18 drivers with a full license with conditions may carry no more than two passengers under 21, siblings excepted.

Restrictions end and you hold a full, unrestricted license at 18, provided your record stays clean.

District of Columbia rules worth knowing for the test

Signs and most rules are the same nationwide, but each state has its own laws — and the DMV test asks about them.

Learner permit holders and drivers under 18 may not use a phone or other electronic device while driving, even hands-free, except in an emergency.
With a learner permit you may drive only between 6 a.m. and 9 p.m., with a licensed driver 21 or older in the seat beside you.
After passing the knowledge test, you must visit a DC DMV service center within 14 business days or the result is not honored.
Using a cellphone or watch during the knowledge test counts as cheating: the test is failed and you cannot retest for 60 days.
