Take a free, untimed District of Columbia DMV practice test in the real exam format: 30 questions, 24 correct to pass. Fresh random questions every attempt.
The District of Columbia knowledge test is a single 30-question exam covering road signs and the rules of the road together. You need 24 correct (80%) to pass.
Answer: Whoever arrives first
At an uncontrolled intersection, the vehicle that arrives first generally has the right-of-way.
Right-of-Way
Answer: Yes, after a full stop, yielding to pedestrians and traffic, unless a sign prohibits it
DC does not statutorily ban right turns on red citywide — they are legal after a full stop and yielding, unless a specific sign prohibits the turn at that location.
Signals
Answer: 3 points
Speeding 11-15 mph over the limit adds 3 points.
Point System
Answer: No closer than 10 feet
DC prohibits parking within 10 feet of a fire hydrant.
Parking Rules
Answer: Children under 2 years old AND under 40 lbs OR under 40 inches
DC requires rear-facing seating for children under 2 years old who are also under 40 pounds or under 40 inches tall.
Child Passenger Safety
Answer: Traffic already circulating within the circle
When entering a traffic circle, vehicles must yield to traffic already circulating within it — the same basic principle that applies to any roundabout.
Right-of-Way
Answer: Right turn on red is legal by default in DC, so downtown intersections that want to prohibit it must post a sign saying so
Because right-on-red is legal by default in DC, individual intersections that want to restrict it — common in DC's dense downtown grid — must post a sign to do so, which is why you'll see many of them.
Signals
Answer: 4 points
Speeding 16-20 mph over the limit adds 4 points — one more than the 11-15 mph tier.

Questions and exam format researched against District of Columbia's official driver handbook and state sources. Last verified 19 August 2026.
DC Code and 18 DCMR regulations, researched and verified 2026-08-19: 18 DCMR §2200 (citywide default/alley/school-zone/facility-adjacent speed limits, effective 2/21/2025 — a recent Vision Zero-era reduction from the more typical 25 mph default used by most states; re-verify this figure periodically given how recently it changed); DC Code §50-2201.04 (reckless/aggravated reckless driving); 18 DCMR §§2103-2104 (signals — right on red, red/flashing arrows, flashing red/yellow); DC Code §50-1802 and §50-1807 (seatbelt requirement and fine); DC Code §50-1731.04 (handheld phone ban for licensed drivers) and §50-1731.05 (stricter all-device ban for learner permit holders); 18 DCMR §303 (point system, thresholds, expiration, and safe-driving credit); DC's GRAD graduated licensing program materials (permit/provisional/full phases, hours, seasonal curfew, driver's-ed-optional status since a 2016 mandate was suspended indefinitely); 18 DCMR §2405 (no-sign-required parking prohibitions); DC Code §50-2201.29 (transit-bus passing law); DC Code §50-1703 (child passenger safety, verbatim statute). Mock exam config is a CLEARLY FLAGGED ESTIMATE: DC DMV does not publish an official question count or passing percentage, and a unified (non-split) knowledge test format is inferred rather than confirmed — this module uses { signCount: 0, signPassCount: 0, ruleCount: 30, rulePassPct: 0.8 } as a placeholder pending an official published figure; re-verify against dmv.dc.gov before treating it as authoritative. Deliberately excluded rather than invented: any work-zone-specific speed provision; a left-turn-on-red rule for one-way-to-one-way streets; whether the seatbelt law is a primary or secondary enforcement offense; a general move-over law for stopped police/emergency/service vehicles (only the narrower transit-bus passing rule was confirmed); a headlight/wiper usage requirement; handicap parking placard specifics and parallel-parking test requirements; a school-bus-specific stop-arm law; a bicycle safe-passing-distance requirement; a night-driving-hours sub-requirement within the 50-hour Parent Supervised Driving Program; and any DC-specific statutory right-of-way rule for traffic circles distinct from ordinary intersection/roundabout law (circles are used here only as route/question flavor, e.g. Dupont Circle, Thomas Circle, Logan Circle). Re-verify all figures periodically, as DC Code, DCMR regulations, and DMV program details change over time.
