DC DMV Test — Key Facts
Knowing the specific numbers and rules before your DC written knowledge test gives you a real advantage. Here are the key facts for this test:
- DC DMV test: 25 questions, 80% required to pass (20 correct minimum)
- Hill parking uphill with curb: Turn wheels left (away from curb) — vehicle rolls into curb if brakes fail
- Hill parking downhill with curb: Turn wheels right (toward curb) — vehicle rolls into curb if brakes fail
- Red curb in DC: No stopping, standing, or parking at any time — common near fire hydrants, driveways, and bus stops
- Yellow curb in DC: Commercial loading/unloading zone — check posted time restrictions
- DC roundabouts: DC has many traffic circles — Dupont Circle, Logan Circle, Thomas Circle — always yield to circulating traffic
How to Use This Test Effectively
Getting the most out of your DC DMV practice time takes more than clicking through questions. Use these strategies:
- DC's curb color system is used extensively throughout the city. Red curbs are common near fire stations, bus stops, and driveways. Yellow curbs mark commercial loading zones. Know both colors — they appear on every version of the DC DMV exam.
- Hill parking wheel direction follows one rule: protect against runaway. Always position your wheels so the vehicle rolls into the curb, not into traffic. Uphill with curb: wheels left. Downhill with curb: wheels right.
- DC's traffic circles require extra caution. Washington DC's famous circles — Dupont, Logan, Thomas, Scott, Mt. Vernon — are large roundabouts. Yield to all vehicles already circulating before you enter. Signal your exit.
- Motorcycle following distance is tested specifically in DC. Leave extra following distance behind a motorcycle — at least 3-4 seconds. Motorcycles can stop faster than cars and may need to maneuver around road hazards or potholes common on DC urban roads.
- DC has heavy pedestrian traffic at all hours. DC's dense urban grid — especially near Capitol Hill, the National Mall, and downtown — means high pedestrian volumes. Always yield to pedestrians in marked crosswalks and at all intersections.
Frequently Asked Questions
How many questions are on the DC DMV written test?
25 questions. You must answer at least 20 correctly (80%) to pass the DC DMV written knowledge test.
What does a red curb mean in Washington DC?
No stopping, standing, or parking at any time. Red curbs in DC are used near fire hydrants, fire station driveways, bus stops, and other areas requiring constant clear access.
What does a yellow curb mean in DC?
A commercial loading and unloading zone. The exact time restrictions and eligible vehicles are shown on posted signs. Generally, drivers may briefly stop to load or unload goods during posted hours only.
How should I position my wheels when parked uphill next to a curb?
Turn your front wheels to the left (away from the curb). If your brakes fail and the vehicle rolls backward, the wheels will catch on the curb and stop the vehicle from rolling into traffic.
What should I do when entering a traffic circle or roundabout in DC?
Yield to all vehicles already circulating in the circle before entering. Enter only when there is a safe gap in traffic. Travel counterclockwise. Signal when you are about to exit.
