DC DMV Practice Test 3
Practice Test 3 introduces additional DC-specific scenarios — parking downhill without a curb, what to do when your accelerator sticks while driving on DC streets, driving safely in strong wind conditions near the National Mall and other open DC areas, DC work zone compliance on major construction projects, left turn procedure from two-way streets, fog driving on DC's Rock Creek Parkway and the Potomac waterfront, and the entry procedure for DC's many traffic circles and roundabouts.
Why Take This DC Practice Test?
Practice Test 3 covers the scenario-specific rules that require applying DC law precisely — sticking accelerator, strong crosswinds, and turning from a two-way street. These are frequently missed because they require knowing the exact correct sequence of actions, not just a general sense of the rule.

DC DMV Topics Covered in This Test
Every question in this test is drawn from the official DC Driver Handbook. Here is a breakdown of the specific topics covered:
- Parking Downhill Without Curb — wheels turned right (toward shoulder)
- Sticking Accelerator — shift to neutral, brake, steer to safety, turn off ignition if needed
- Strong Wind Driving — firm grip on wheel, reduce speed, watch for gusts near open areas
- DC Work Zone Compliance — reduce speed, obey flaggers, stay alert for lane changes
- Left Turn from Two-Way Street — yield to oncoming traffic and pedestrians before turning
- Fog Driving Technique — low beams only, reduce speed to visible stopping distance
- Approaching Emergency Vehicle on Roadside — DC Move Over obligation
- Flashing Yellow Arrow — may turn but must yield to oncoming and pedestrians
- Solid White Stop Line — stop before the line, not at or past it
- Aggressive Driving Response — do not engage, create distance
- Motorcycle Following Distance — extra space required, at least 3-4 seconds
- Yellow Diamond Merging Arrow — lane merge ahead, prepare to adjust
- Broken White Lane Line — lane changes permitted when safe
- Lane Reduction Sign — upcoming reduction in number of lanes, merge early
- Skid Recovery — ease off gas, steer toward intended direction
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:
- Parking downhill without curb: Turn wheels right (toward shoulder) — vehicle rolls toward edge rather than traffic if brakes fail
- Sticking accelerator: Shift to neutral immediately, brake firmly, steer to a safe stop — do not turn off ignition while moving (power steering and brakes may fail)
- Strong wind in DC: Common near the National Mall, Tidal Basin, and along the Potomac — grip wheel firmly and reduce speed
- DC Move Over law: Move one lane away from stopped emergency vehicles with flashing lights, or slow significantly
- DC work zones: Major ongoing projects on I-395, Route 1, and DC connector roads — obey all posted work zone speeds
- Fog on Rock Creek Parkway: Dense early-morning fog is common — use low beams and reduce speed
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:
- Parking downhill without a curb — wheels right toward the shoulder. Without a curb to catch the vehicle, turning wheels toward the shoulder ensures the car rolls away from traffic (toward the edge of the road) if brakes fail. This applies whether facing uphill or downhill without a curb.
- Sticking accelerator has a specific sequence in DC. Shift to neutral first — this disconnects the engine from the wheels. Then brake firmly. Steer to a safe location off the road. Do not turn off the ignition while moving — you will lose power steering and brakes.
- Strong wind is a real hazard near DC's open monuments area. The Mall, Tidal Basin, and Hains Point are exposed to strong crosswinds with no wind breaks. Grip the wheel firmly and reduce speed when driving through these open areas.
- DC's Move Over law applies on all DC roads. When approaching a stopped emergency vehicle, police vehicle, or utility vehicle with flashing lights on the roadside, move one lane away or slow significantly. This applies on DC's urban streets as well as highways.
- Left turns in DC's dense traffic require patience. On DC's busy streets — K Street, Pennsylvania Avenue, Georgia Avenue — left turns across heavy traffic require waiting for a complete safe gap in oncoming traffic and ensuring all pedestrians have cleared.
Frequently Asked Questions
What does Practice Test 3 focus on?
Practice Test 3 covers downhill parking without a curb, sticking accelerator emergency procedure, strong wind driving near DC's open areas, work zone compliance, left turn procedure, fog driving on DC's parkways, and the Move Over obligation.
Which way do I turn wheels when parking downhill without a curb?
Turn your front wheels to the right (toward the shoulder) whether facing uphill or downhill when there is no curb. This positions the wheels so the vehicle rolls away from traffic rather than into it if the brakes fail.
What should I do if my accelerator sticks while driving in DC?
Shift to neutral immediately to disconnect the engine from the drive wheels. Apply the brakes firmly to slow the vehicle. Steer to a safe location off the roadway. Do not turn off the ignition while moving — you will lose power steering and assisted braking.
Why is strong wind a concern for DC drivers?
Washington DC's open monument areas, the National Mall, Tidal Basin, and roads along the Potomac River are exposed to strong crosswinds with no natural windbreaks. Grip the wheel firmly and reduce speed when driving through these open areas.
Does DC have a Move Over law?
Yes. DC law requires drivers to move one lane away from stopped emergency vehicles, police vehicles, and utility vehicles with flashing lights on the roadside when it is safe to do so. If you cannot safely change lanes, you must slow down significantly.
