DC Motorcycle Permit Test flashcards
DC Motorcycle Permit Test · Build recall with a focused review session.
32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Friction zone
- The range of clutch-lever travel where the engine starts to pull the bike. Riders hold the throttle steady and modulate this zone to control speed in slow turns and starts.
- Countersteering
- At speeds above walking pace, pressing the grip on the side you want to turn toward leans the bike and makes it turn that direction. It is the normal way to initiate a turn.
- Throttle free play
- The small amount of grip rotation before the throttle cable begins to open the throttle. Excess play or a grip that does not snap back to idle is a defect to fix before riding.
- T-CLOCS inspection
- A pre-ride checklist covering Tires, Controls, Lights, Oil, Chassis, and Stands. Working through it in order catches low tires, frayed cables, and loose parts before a ride.
- Cold tire pressure
- Tire pressure measured before the tires heat up from riding. It is the correct reading to compare against the manufacturer's specification, because warm tires read higher.
- Head check
- A quick turn of the head to look into the blind spot that mirrors do not cover. Required before lane changes, merges, and pulling away from a stop.
- Trail braking
- Continuing to apply brakes lightly while entering a curve, then tapering off as the bike leans. It must be smooth; grabbing the front brake while leaned can cause a slide.
- Two-second rule
- A minimum following distance in good conditions, measured from when the vehicle ahead passes a fixed object until you reach it. Add a second for rain, night, or poor surfaces.
- Lane position left third
- Riding in the left portion of the lane keeps you visible in the mirrors of cars ahead and away from curb debris, parked-car doors, and the oily center strip.
- Oily center strip
- The middle of a traffic lane collects dripped oil and coolant from cars, especially at intersections. It is slickest when wet, so ride in the tire tracks instead.
- Blind spot rule
- If you can see a driver's face in their mirror, they can usually see you. Avoid riding where that reflection is not visible, especially beside large vehicles.
- Three-second truck gap
- A minimum following distance behind a large truck. It gives the driver room to see you in the mirrors and gives you room to see past the trailer.
- Conspicuity
- Being visible to other drivers. Achieved with headlights on, bright or reflective gear, and lane positions that keep you out of blind spots and glare.
- Staggered formation
- A group riding pattern where riders alternate left and right lane positions, keeping a two-second gap to the rider ahead. It preserves escape space while keeping the group compact.
- Left-turn conflict
- The most common motorcycle-car crash: a car turns left across the rider's path. Riders reduce speed, cover the brakes, and stay out of the car's path until it commits.
- Right turn on red
- Permitted after a complete stop, a yield to pedestrians and cross traffic, and only where no sign prohibits it. It is a stop-then-yield maneuver, not a rolling turn.
- Acceleration lane merge
- The freeway on-ramp lane used to build speed to match traffic, then signal, head-check, and merge into a gap. Stopping at the end of the ramp is avoided unless traffic forces it.
- Door zone
- The width of a parked car's opening door. Riding there risks a sudden door strike, so keep at least a door's width of clearance or slow enough to stop.
- Truck right-turn swing
- Large trucks swing wide left before turning right and have deep blind spots along the trailer. Never pass a truck on the right or linger beside it.
- Complete stop
- A full halt with a foot down before proceeding at a stop sign or red light. Rolling stops and stops past the line or crosswalk are violations.
- Turn lane choice
- Turn from the lane closest to your direction of travel and stay in that lane through the turn. From a one-way to a one-way street, the left lane may be used.
- Following distance
- The time gap to the vehicle ahead, at least two seconds in good conditions and more when wet, dark, or gravelly. It is measured by counting to a fixed roadside object.
- DOT helmet
- A helmet meeting federal safety standards, required for riders and passengers in DC. It should fit snugly, sit level on the head, and have a fastened chin strap.
- Riding impaired
- Riding after alcohol, cannabis, prescription drugs, or with severe fatigue. Balance, throttle control, and judgment degrade before the rider feels affected.
- Twelve-second scan
- Looking at least 12 seconds down the road to spot gravel, potholes, wet leaves, and stopped traffic early enough to brake or change lane position smoothly.
- Swerve technique
- A quick lane change around a hazard, done separately from hard braking. Push the grip toward the direction of the swerve, keep your eyes level, then straighten and brake.
- Slippery surfaces
- Painted lines, metal grates, manhole covers, and railroad tracks lose traction when wet. Cross tracks at close to a right angle and avoid braking or leaning on these surfaces.
- Fatigue impairment
- Tiredness slows reaction time and causes brief lapses in attention. It is treated as impairment: stop, hydrate, and rest rather than pushing through a long ride.
- Over-the-ankle boots
- Footwear that covers the ankle and has a sturdy sole. It protects against abrasion and ankle injury and keeps feet secure on the pegs and controls.
- Eye protection
- A face shield or shatterproof glasses that meet safety standards. Required with an open-face helmet to block wind, insects, and road debris from the eyes.
- Braking while leaned
- Applying brakes in a curve reduces available traction and can cause a slide. Brake in a straight line before the turn, then release and lean through the curve.
- BAC limit
- The blood alcohol concentration at which a rider 21 or older is legally impaired in DC: 0.08 percent. Riders under 21 face zero tolerance for any alcohol.
