Washington DC DMV Permit Practice Test

The DC DMV knowledge test is your gateway to a learner's permit — and it comes in two different versions depending on your age. The DC DMV will not tell you which questions you missed if you fail; you only get the verdict. Knowing the format before you walk in is a real advantage.

• ✓
  Under-18 (GRAD program) exam30 questions. Pass at 24 correct (80%). This is the test you take if you're under 18 and enrolling in DC's Graduated Driver Licensing program.
• ✓
  Adult exam (age 21+)25 questions. Pass at 20 correct (80%). If you're 21 or older getting your first DC license, you take the shorter adult test — not the GRAD version.
• ✓
  Application fees$20 learner's permit fee + $10 knowledge test fee = $30 total due at the DC DMV office.
• ✓
  Bring with youProof of identity, DC residency, and your Social Security number. The DC DMV requires these to issue any driver credential — don't show up without all three.
• ✓
  Driver educationDriver-ed is NOT required in DC. The DC DMV explicitly states it is optional but recommended for first-time drivers. You can take the knowledge test without any formal course.
• ✓
  Why DC catches first-timers off-guardDC's bank leans heavily on traffic laws and safety scenarios — 184 traffic-law questions and 137 safety questions. Sign identification is only 78 of 454 total questions. Students who over-study signs and under-study right-of-way and speed rules often fall short of the 80% threshold.

Traffic laws, safety scenarios, and road signs together account for nearly 90% of DC's 454-question bank. Nail those three categories and you're most of the way there. Signs alone won't save you — DC tests heavily on right-of-way, speed management, and impairment rules.

• ✓
  Traffic laws (~40% of the bank)184 questions covering right-of-way, turning, passing, lane changes, and school bus rules. This is DC's single biggest category — more than road signs and safety combined.
• ✓
  Safety scenarios (~30% of the bank)137 questions on hazardous conditions: fog, ice, fatigue, distracted driving, emergency situations. DC tests real decision-making, not just rule recitation.
• ✓
  Road signs (~17% of the bank)78 questions on sign shapes, colors, and meanings. Diamond-shaped yellow signs are warnings; downward triangles mean yield; crossbuck signs indicate railroad crossings.
• ✓
  Signal distanceDC law requires signaling at least 100 feet before any turn, lane change, or pulling away from a curb — even when no one appears to be around. (Q24071, Q24186)
• ✓
  Railroad crossingsStop at least 15 feet from the nearest rail when the lights are flashing or the gate is down. Never drive around a lowering gate under any circumstances. (Q23987, Q24032)
• ✓
  Following distanceIncrease your following distance in rain, snow, or ice — the bank does not test a single canonical second count, but explicitly flags 'four-second following distance' as a distractor in Q23971. Adjust based on conditions.
• ✓
  BAC limit (21+)0.08% or higher is illegal. For drivers 21 and older, this is the hard legal line — at or above this BAC you are per se impaired in DC. (Q24388)
• ✓
  Any alcohol matters under 21The bank is explicit: ANY amount of alcohol in the blood can impair judgment and physical coordination, even below the legal limit. DC does not test a specific 0.02% threshold — the tested answer is that any alcohol affects you. (Q24245)
• ✓
  Chemical test refusalRefusing a breathalyzer or blood test triggers automatic license suspension under DC's implied consent law. Refusing is not a legal workaround — it's an automatic penalty.
• ✓
  Speed managementIn traffic moving at 50–55 mph, staying within that speed range is safest — not driving a few mph faster or slower than the flow. In school zones and residential areas, obey posted limits. (Q24066)

These are the categories that sink more first-time DC test-takers than any other. The questions are written to catch students who half-remembered a rule — not ones who looked it up once.

• ✓
  Three-car right-of-way scenariosAt a four-way stop, yield to the car on your right when two vehicles arrive simultaneously. With three cars, the chain of 'yield to the right' still applies — most people get the two-car case right and fumble the three-car version.
• ✓
  School bus — stop and wait it outWhen a school bus has its red lights flashing, stop and stay stopped until the lights stop flashing and the stop arm retracts. You cannot proceed just because children appear to have boarded. If the bus is on the opposite side of a divided highway (physical median), you may proceed. (Q24007, Q24083)
• ✓
  Hill parking — downhillTurn your front wheels toward the curb (or edge of road if no curb). This way, if the car rolls, it rolls away from traffic. (Q24294, Q24322, Q24354)
• ✓
  Hill parking — uphill with a curbTurn your wheels AWAY from the curb. The curb catches the tire if the car rolls. This is the counterintuitive one — most people get downhill right and get uphill wrong. (Q24367)
• ✓
  Impairment starts before 0.08%0.08% is the legal threshold, not the point where impairment begins. The DC bank specifically tests that any alcohol can affect your judgment and coordination — impairment and illegality are two different bars. (Q24245)
• ✓
  'Always' and 'never' trapsDC questions use 'always' and 'never' correctly in some contexts — for example, you must ALWAYS signal even when no one is visible (Q23976). Read every option. Don't auto-eliminate 'always' choices.
• ✓
  Passing a bicyclistSlow down and give the cyclist as much space as possible. When making a right turn at an intersection, yield to any bicyclist traveling between you and the curb. Crowding a bike is both dangerous and tested. (Q24199, Q24227)

Reading alone reliably tops out around 60% on the real test. Students who pass first try use three loops: read once, drill once, listen once. That's it.

• ✓
  Loop 1 — read the handbookDownload the DC DMV Automobile Driver Manual free from dmv.dc.gov. Read it once — don't try to memorize. This guide compresses the highest-yield content into bullets so you can review faster.
• ✓
  Loop 2 — drill the practice examsTake the free 40-Q exam below cold. Anything under 32/40 means drill the categories you missed and retake. DC's bank has 454 questions across 11 distinct exams — use all of them.
• ✓
  Loop 3 — listen along on YouTubePlay the DC DMV traffic laws and road signs videos in the background the day before your test. Hearing questions out loud reinforces patterns faster than re-reading.
• ✓
  Sleep beats crammingMemory consolidates overnight. A full night's sleep before the test is worth more than two extra hours of late-night review.
• ✓
  Study signs visuallyNever read sign descriptions in text only. Look at the actual shape and color — the test shows you the sign image, not a written description. Diamond shapes, downward triangles, and crossbucks look different on paper than they sound.
• ✓
  Read every option before pickingDC writes plausible wrong answers. Many questions have 'All of the above' as the correct answer — if you stop at option B, you'll miss it. Most DC questions use 3–4 options.

Passing the knowledge test gets you a learner's permit — not a full license. DC's Graduated Driver Licensing (GRAD) program layers on restrictions that stay with you until you turn 18, with the full GRAD program ending at 21. The rules are specific and worth knowing before you get behind the wheel.

• ✓
  Learner permit — supervision requiredYou may only drive with a licensed driver 21 or older seated in the passenger seat. No exceptions. Solo driving on a learner's permit is illegal.
• ✓
  Learner permit — hours of operationLearner permit holders may only drive between 6:00 am and 9:00 pm. No nighttime driving at all on the learner permit — not with supervision, not ever.
• ✓
  Provisional license — weeknight curfew (Sep–Jun)Sunday through Thursday: you must be off the road by 10:59 pm. This is the school-year weeknight rule.
• ✓
  Provisional license — weekend curfew (Sep–Jun)Friday and Saturday: you may drive until 11:59 pm. One hour later than weeknights — but still a hard cutoff.
• ✓
  Summer curfew (Jul–Aug)Every day in July and August: drive until 11:59 pm. The weekend rule applies all week during summer months.
• ✓
  Passenger restrictionProvisional license holders may not carry more than 2 passengers under age 21, unless those passengers are your siblings. Family exceptions apply.
• ✓
  When restrictions liftCurfew and passenger restrictions ease when you turn 18. The full GRAD program concludes when you turn 21 — at that point you exit the graduated system entirely and hold a standard DC driver's license.
