Every topic on the SOS motorcycle knowledge test, organized so you can study one section at a time.
The Michigan motorcycle knowledge test is built from the official Michigan Motorcycle Operator Manual (SOS-116). Score 16 of 20 correct (80%) to pass. The guide below walks through the 12 core topics the test draws from. Tap any section to expand it, then use the practice test to check what you have learned.
Before every ride, be able to find and use the throttle, clutch lever, gearshift, front brake lever, rear brake pedal, and handlebars without looking — there are six primary controls. The manual stresses that a motorcycle needs more attention than a car, so make a complete check before every ride (Before You Ride).
Required helmets must meet U.S. DOT standards. A full-face helmet gives the most protection because it covers your whole head and face, and a shatter-resistant face shield protects your whole face while goggles protect only your eyes (Before You Ride).
Sit so your arms steer the motorcycle rather than hold you up, keep your knees against the tank and feet on the pegs, and keep your right wrist flat to avoid too much throttle. Your motorcycle has two brakes — always use both, every stop. The front brake supplies 70 percent or more of your stopping power, so squeeze it firmly and progressively (Basic Operation).
Many riders crash by entering curves too fast. Use four steps: SLOW, LOOK, PRESS, ROLL. Slow before the turn, look through it by turning just your head, press the handgrip in the direction of the turn to lean — press left, lean left, go left — and roll on the throttle to keep the motorcycle steady (Basic Operation, Roadway Management).
Each lane gives a motorcycle three paths of travel, and there is no single best position — you change it as traffic and hazards change. Choose the path that helps you see and be seen, avoids blind spots and surface hazards, and keeps a space cushion. The manual recommends new riders keep at least a four-second following distance (Street Strategies).
Experienced riders use SEE — Search, Evaluate, Execute — to spot hazards and act early. Search aggressively ahead, to the sides, and behind; evaluate how hazards could interact to create risk; and execute by adjusting your speed and position and communicating with your lights or horn (Street Strategies).
About 40 percent of motorcycle-car crashes happen at intersections, usually when a driver turns left in front of a rider. Drivers often say they never saw the motorcycle, so keep your headlight on — a motorcycle with its light on is twice as likely to be noticed — wear bright clothing, and signal every time (Street Strategies).
Two skills save you in a tight spot: stopping quickly and swerving. To stop quickly, use both brakes at the same time, squeezing the front lever firmly — never grabbing it. When there is no room to stop, swerve by pressing the handgrip on the side you want to go, then press the other grip to recover (Roadway Management).
Wet pavement, gravel, metal grates, and lane markings reduce traction. Slow before a slippery surface, avoid sudden moves, and use both brakes gently — the front brake still works. Pavement is most slippery just after rain starts, so ride in the tire tracks left by cars and avoid the oily center (Roadway Management, Special Riding Situations).
A pre-ride check catches trouble before traffic does. If a tire goes flat, hold the grips firmly, ease off the throttle, keep a straight course, and edge to the side of the road — you will seldom hear it go (Special Riding Situations).
Only experienced riders should carry passengers or large loads, because the extra weight changes how the motorcycle handles, balances, and stops. A passenger sits behind you, as far forward as possible, with feet on the footrests at all times (Passengers, Cargo and Group Riding).
Alcohol is a major contributor to motorcycle crashes — nearly 40 percent of riders killed had been drinking — and even one drink can affect your ability to ride. In Michigan a BAC of 0.08 or greater is operating while intoxicated, and 0.17 or greater is a high-BAC offense (Being in Shape to Ride, Michigan Motorcycle Laws).
