Every topic on the DMV motorcycle knowledge test, organized so you can study one section at a time.
The Colorado motorcycle knowledge test is built from the official Colorado Motorcycle Operator's Handbook (DR 2336). 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.
Sit far enough forward with your arms slightly bent so you can use your arms to steer the motorcycle rather than hold yourself up (Colorado Handbook §3.1). Hold the handle grips firmly, keep your knees against the gas tank to help your balance, and keep your feet firmly on the foot pegs near the controls.
Crashes are not rare among beginning riders, and one of every five reported motorcycle crashes results in head or neck injuries (Colorado Handbook §2.1). Unhelmeted riders are three times more likely to die of head injuries than helmeted riders. Colorado law requires a helmet for every operator and passenger under 18; eye protection is required of every rider at every age.
Your motorcycle has two brakes — always use both at the same time. On a two-wheel motorcycle and a sidecar rig the front brake provides the most stopping power; on a three-wheel motorcycle the rear brake provides the most power (Colorado Handbook §3.3). Squeeze the front brake — never grab it. To completely stop, roll off the throttle, apply the brakes, and squeeze the clutch.
Riders crash by taking curves too fast, then running wide or braking too hard into a skid. Use four steps: SLOW, LOOK, LEAN, ROLL (Colorado Handbook §3.2). Slow before the turn, look through the turn, press the handgrip toward the turn to lean — press left, lean left, go left — and roll on the throttle through the turn.
Each marked lane gives a motorcyclist three possible paths of travel, and there is no single best position — ride where it is easiest for drivers to see you (Colorado Handbook §5). No portion of the lane needs to be avoided, including the center; unless the road is wet, even the oily strip gives enough traction. The best protection you can have is distance — a cushion of space all around your motorcycle.
Experienced riders use SIPDE — Scan, Identify, Predict, Decide, Execute — a five-step process to make judgments and take action in traffic (Colorado Handbook §7). Scan aggressively ahead, to the sides and behind; identify hazards; predict where a collision might occur; decide how to act; and execute by communicating, adjusting speed, and adjusting position.
In crashes with motorcyclists, car drivers often say they never saw the motorcycle (Colorado Handbook §4). Wear bright orange, yellow or green clothing, keep your headlight on at all times — use the high beam in daylight — and use your turn signals every time you turn, change lanes, or use a freeway ramp.
Knowing when and how to stop or swerve are two skills critical to avoiding a collision (Colorado Handbook §10). To stop quickly, apply both brakes at the same time — squeeze the front brake firmly without grabbing it, and apply the rear brake hard without locking it. When there is no room to stop, swerve instead.
Wet pavement, gravel, mud, snow, ice, lane markings and steel plates all reduce traction. Slow down before you reach a slippery surface, avoid sudden moves, and use both brakes gently (Colorado Handbook §8). When it starts to rain, ride in the tire tracks left by cars and avoid the oily center strip until the surface oil washes away.
A motorcycle needs more frequent attention than a car, and a minor failure can cause a crash — make a complete check before every ride (Colorado Handbook §2.2). Check tire pressure, fluid levels and leaks, both headlight beams, all four turn signals, the brake light from both controls, the throttle (it should snap back), the mirrors, the brakes and the horn.
Only experienced riders should carry passengers or large loads, because the extra weight changes how the motorcycle handles, balances and stops (Colorado Handbook §13). A passenger must have a proper seat and their own foot pegs, should get on after you start the engine, and should hold firmly to your waist, hips or belt.
It is illegal to operate a motorcycle on a Colorado public road without a license that authorizes it. The general 'M' endorsement covers two- and three-wheel motorcycles; the separate '3' endorsement covers three-wheel motorcycles only (Colorado Handbook §1). To add an endorsement you must be at least 16 and pass a driving-record review, a physical-aptitude review, a vision test, the written knowledge test, and the skills test.
Source: Sources differ on this state's test details; the most credible consensus is shown. Confirm with the state agency. The motorcycle knowledge test consists of 25 questions; you must answer 20 correctly (80%) to pass. The question count is third-party consensus — the official DMV page does not publish it. An approved Basic Rider Course can waive the on-cycle skills test, but every applicant must still pass the written knowledge test.
