Every topic on the DOR motorcycle knowledge test, organized so you can study one section at a time.
The Missouri motorcycle knowledge test is built from the official Missouri Motorcycle Operator Manual (Form 2332). Score 20 of 25 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 you ride, be able to find and work the throttle, clutch, front brake lever, rear brake pedal, gear shift, turn signals, horn, headlight switch and engine cut-off switch without looking for them (Form 2332, p.7). Sit so your arms steer the motorcycle rather than hold you up, keep your knees against the tank and your feet on the footrests, and start with your right wrist flat to avoid using too much throttle (Form 2332, p.12).
Your single best protection in a crash is a securely fastened, quality helmet that meets U.S. DOT standards; helmeted riders are three times more likely to survive head injuries (Form 2332, p.4). A face shield protects your whole face, while goggles protect only your eyes — and a windshield is not a substitute for either (Form 2332, p.5).
Your motorcycle has two brakes — always use both at the same time. The front brake is more powerful and can provide at least 70% of your total stopping power, and is safe when you squeeze, never grab, the lever (Form 2332, p.13). Maximum straight-line braking is fully applying both brakes without locking either wheel (Form 2332, p.29).
Riders crash by taking curves too fast, then running wide or braking too hard. Use four steps: SLOW, LOOK, PRESS, ROLL (Form 2332, p.14). Slow before the turn, look through it to where you want to go, press the handgrip in the direction of the turn to lean — press left, lean left, go left — and roll on the throttle through the turn to stay stable.
Each lane gives a motorcycle three paths of travel, and no part of the lane — including the center — must always be avoided (Form 2332, p.15). Choose the path that helps you see and be seen, avoids blind spots and surface hazards, and leaves an escape route. Keep at least a two-second following distance, opening it to three seconds or more in heavy traffic, on slippery roads, or when you cannot see ahead (Form 2332, p.16).
Experienced riders use MSF's three-step SEE strategy — Search, Evaluate, Execute — to spot hazards and act early (Form 2332, p.20). Search aggressively ahead, to the sides and behind. Evaluate how road conditions, traffic-control devices and other vehicles could create risk. Execute by communicating with lights or horn and adjusting your speed and position.
Intersections hold the greatest potential for conflict — over half of car/motorcycle crashes come from a driver entering the rider's right-of-way, most often a car turning left (Form 2332, p.21). Drivers often say they never saw the motorcycle. Keep your headlight on — a motorcycle with its light on is twice as likely to be noticed — and use your turn signals every time, even when your move seems obvious (Form 2332, p.24-25).
In a tight spot, two skills save you: stopping quickly and swerving. To stop quickly, apply both brakes at the same time, squeezing the front lever firmly and progressively — never grabbing it (Form 2332, p.27). When there is no room to stop, swerve: press the handgrip on the side of your escape to lean the bike quickly, then press the opposite grip to recover (Form 2332, p.28-29).
Wet pavement, gravel, mud, snow, ice, painted lines and metal plates all reduce traction. Slow before you reach a slippery surface, avoid sudden moves, and use both brakes gently (Form 2332, p.31). When it starts to rain, ride in the tire tracks left by cars and avoid the oily center strip until surface oil washes away (Form 2332, p.31-32).
A motorcycle needs more frequent attention than a car, so make a complete check before every ride using the T-CLOCS checklist — Tires, Controls, Lights, Oil, Chassis and Stands (Form 2332, p.8, p.59). On the road, 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 (Form 2332, p.33).
Extra weight changes how a motorcycle handles, balances and stops, so only experienced riders should carry passengers or large loads (Form 2332, p.35). Have the passenger mount only after the engine is started and the bike is in neutral, hold your waist, hips or belt, keep both feet on the footrests, and lean with you (Form 2332, p.36). Keep cargo low and forward, over or in front of the rear axle, and fasten it securely (Form 2332, p.37-38).
Alcohol and other drugs degrade your ability to think clearly and ride safely more than any other factor — as little as one drink affects performance, and impairment begins well below the legal limit (Form 2332, p.42, p.44). In Missouri an adult with a blood-alcohol concentration of 0.08% or higher is legally intoxicated, and alcohol leaves the body at only about one drink per hour (Form 2332, p.43-44).
