South Dakota Motorcycle Test Cheat Sheet
A condensed, skimmable recap of the rules most worth knowing cold before your exam — distilled from our full South Dakota practice question bank. This isn't a replacement for the South Dakota Driver's Manual; confirm anything time-sensitive with South Dakota DPS.
South Dakota Motorcycle Licensing
- The written exam is 25 questions, and 20 correct (80%) passes it.
- The minimum age for a motorcycle instruction permit is 14, matching the state's car permit age; a full motorcycle license requires 16 and passing vision, both knowledge tests, and a driving test.
- A motorcycle instruction permit holder may only ride during daylight hours, supervised by a licensed rider 18+, and may not carry a passenger.
- Completing an approved Basic Rider Course automatically grants an M endorsement, without needing to take the state's own knowledge and skills tests.
- Every operator and passenger under 18 must wear a helmet; a rider 18 or older isn't required to wear one, and a rider under 18 with an endorsement also can't carry a passenger or ride 10 p.m. to 6 a.m.
South Dakota Road Hazards
- The Sturgis Motorcycle Rally brings a massive seasonal surge in motorcycle traffic across the state every August.
- Cross railroad tracks and grooved pavement as close to a right angle as possible so a narrow front tire doesn't catch.
Lane Positioning
- Split the lane mentally into left, center, and right thirds, and pick whichever gives the best visibility or space.
- Sitting alongside a car for an extended stretch risks landing you in that driver's blind spot.
Motorcycle Controls
- The front brake is a hand lever on the right handlebar; the rear brake is a foot pedal at the right foot peg.
- The friction zone is the partial-engagement range of the clutch where power starts transferring smoothly.
- Rolling off the throttle gives engine braking, slowing the bike without touching a brake at all.
Braking Techniques
- Threshold braking — squeezing right up to the edge of lockup — produces the shortest stop without a skid.
- A locked rear wheel is generally corrected by releasing the rear brake and letting traction return.
- A bike leaned into a curve has less traction margin, so hard braking there raises skid risk.
Cornering & Turning
- Countersteering — a brief, opposite press on the handlebar — is what actually leans a motorcycle into a turn at riding speed.
- Look toward where the turn exits rather than at the pavement right in front of you.
Pre-Ride Mechanical Inspection
- A quick check before riding is meant to catch a developing mechanical issue before it becomes a breakdown or hazard.
- Go past tread depth: tire pressure and condition, chain or belt tension, and how the brakes feel all matter.
Intersections & Visibility
- A disproportionate share of motorcycle crashes happen at intersections, usually because a driver never noticed the rider.
- Having the right-of-way doesn't guarantee a driver actually sees you — cover the brake and stay alert regardless.
Sharing the Lane with Cars
- Motorcycles have blind spots too — check directly before a lane change, since mirrors alone don't cut it.
- A driver about to turn right often doesn't fully check for a motorcycle approaching from behind.
Night Riding
- A single headlight gives drivers less to judge your distance and speed by than a car's two.
- Slow down and add following distance after dark, since hazards take longer to notice.
Impairment
- Balancing and controlling a motorcycle takes more continuous coordination than driving a car.
- A sober ride, a rideshare, or leaving the bike overnight are the real fixes.
Passengers, Cargo & Group Riding
- A passenger adds weight that lengthens stopping distance and shifts the bike's balance.
- Load cargo low and toward the front, keeping the center of gravity close to where the bike expects it.
- Smaller groups are easier to keep together through intersections and easier for traffic to pass safely.
