Every topic on the DOL motorcycle knowledge test, organized so you can study one section at a time.
The Washington motorcycle knowledge test is built from the official Washington Motorcycle Operator Manual. Washington uses two knowledge tests — a 50-question motorcycle permit test, then a separate 25-question endorsement test. 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 operate the throttle, clutch, front brake lever, rear brake pedal, gear shift, turn signals, horn, headlight switch, and engine cut-off without looking for them. Sit so your arms steer the motorcycle rather than hold you up, keep your knees against the gas tank, plant your feet firmly on the footrests, and start with a flat right wrist so you do not use too much throttle (p.3-1, 3-2).
The most common cause of rider death in a crash is head injury, so the single most important thing you can do is wear a quality, properly fitted, DOT-compliant helmet. Novelty helmets are not DOT-compliant and may not be worn on public roads. The minimum legal gear in Washington is a DOT helmet and eye protection, but you should wear the most protective gear possible every ride (p.2-2, 2-5).
There is more braking power in the front brake because weight transfers forward when you slow, but the shortest, safest stops come from using both brakes smoothly and progressively without skidding either tire. Squeeze the front brake firmly - never grab it - and when stopped, stay in first gear and check your mirrors in case you must move to avoid a rear-end collision (p.3-8).
A large share of Washington's motorcycle fatalities are single-vehicle corner crashes caused by excessive speed and improper technique. Use four steps - SLOW, LOOK, PRESS, ROLL: reduce speed before the corner, look through the turn to its exit, press the handgrip to lean (press left, lean left, go left), and roll on the throttle to stabilize the bike (p.3-4, 3-8).
Each lane gives you three positions - outside, middle, and inside. There is no single best position; the best one is whatever lets you see and be seen and gives an escape route, and it changes constantly with traffic and hazards. Riding between lanes (lane splitting) and riding on the shoulder are both illegal in Washington (p.5-1, 5-3, 5-4).
Drivers most often say 'I didn't see the motorcycle,' so you own the responsibility to be seen - ride as though you are invisible. Create time and space by scanning at least 12 seconds down the road, identifying hazards early, and keeping an escape route. Be visible with your headlight and bright or reflective gear, and communicate with signals and your brake light (p.2-7, 2-10, 5-6).
The majority of motorcycle versus vehicle collisions happen at intersections, most often when a car turns left across your path. Remain in first gear at intersections, check mirrors, cover your controls, and make sure other road users have actually stopped before you proceed. Watch the road surface for painted lines, leaves, oil, steel plates, grates, manhole covers, and gravel (p.5-7, 5-8).
There are two evasive maneuvers: change speed (slow, stop, or speed up) or change position (swerve or turn). For a quick stop, apply both brakes fully without locking either wheel - squeeze the front firmly and release the rear progressively if it starts to skid. When there is no room to stop, swerve: one countersteer to clear the hazard and another to recover (p.3-9, 3-10).
Wet pavement is most slippery just after the first rainfall of the season, before surface oil washes away. Riding in moderate cold can cause chill, fatigue, or hypothermia, while heat can cause dehydration and fatigue - dress for the conditions so weather does not distract you from riding safely (p.2-5, 2-6, 5-8).
A motorcycle needs more frequent attention than a car; a minor failure that is just an inconvenience in a car can cause a crash on a motorcycle. Do a quick pre-ride inspection before every ride, as routinely as checking the weather. The manual's checklist runs T-O-L-L-S-S (p.2-8, 2-9).
Carrying a passenger or cargo is the rider's responsibility - the extra weight means the motorcycle takes longer to accelerate and to stop and handles differently in corners. A passenger must be at least five years old, have a seat and footpegs, and wear a DOT helmet. Strap cargo down tightly and keep it as low and centered as possible (p.3-10, 3-11).
Alcohol is one of the most common factors in Washington's motorcycle crashes, and impairment begins at the first drink - it quickly degrades judgment, vision, attention, and motor skills. The only thing that removes alcohol from your body is time, at about one hour per drink; coffee, food, or a cold shower do nothing (p.6-1, 6-2).
