All 16 questions in this test

Every question and its answer choices. The correct answers and explanations appear when you take the test above.

  1. An obstacle suddenly appears on the road ahead. What should you do?

    1. Brake hard and keep a straight line right into the obstacle
    2. Slow, counter-steer to the safest side, stay in your lane
    3. Swerve into the oncoming lane right away
    4. Close your eyes and hold the handlebars tight
  2. Why can sand or gravel on pavement be dangerous?

    1. It always hides deep potholes under the surface
    2. It damages the brake lights
    3. It can be even more slippery than wet pavement
    4. It makes the engine overheat
  3. On a grated bridge deck, the motorcycle starts to wander. What should you do?

    1. Steer firmly against the movement to keep straight
    2. Brake hard to stop the wandering
    3. Keep a steady speed and ride straight across
    4. Speed up and change lanes
  4. Where do oil slicks usually build up in a lane?

    1. On painted crosswalks only
    2. In the centre portion of the lane
    3. Along the right curb where water runs off
    4. On the left shoulder
  5. Approaching loose material, where should you shift your body?

    1. Forward onto the tank to load the front wheel
    2. Slightly off the seat and slightly back
    3. Down low in the seat
    4. Far to the inside of the bike
  6. When is wet pavement especially slippery?

    1. Only on gravel roads after a storm
    2. After several hours of steady rain, once puddles have formed
    3. Only when the temperature is below zero
    4. Just after rain starts, before oil and dirt wash away
  7. How can standing on the footpegs help on rough surfaces?

    1. It improves control and absorbs the shock
    2. It lets the rear brake work better
    3. It makes the whole motorcycle lighter on its springs
    4. It lowers your centre of gravity
  8. What does the handbook say about riding on snow and ice?

    1. It is safer than wet pavement
    2. It is safe below 30 km/h
    3. It is fine with good tires
    4. It should be completely avoided
  9. At what angle should you cross railway tracks when other traffic is around?

    1. Exactly 10 degrees
    2. 45 degrees or more
    3. Any angle under 30 degrees
    4. Parallel to the rails
  10. You must ride over an obstacle you cannot avoid. How should you meet it?

    1. Sideways, with both brakes on hard
    2. At a shallow angle, seated firmly on the saddle
    3. At full speed so you skim over it
    4. Head-on, standing slightly with knees flexed
  11. You cannot avoid a slippery surface. Which gear helps traction?

    1. Neutral, coasting with both brakes on
    2. A lower gear, releasing the clutch gradually
    3. Whatever gear gives the most engine noise
    4. A higher gear, releasing the clutch quickly
  12. How can you lighten the front wheel as you reach an obstacle?

    1. Lean forward and brake with the front brake lever
    2. Pull in the clutch and brake hard
    3. Shift to neutral and coast
    4. Lean back slightly and accelerate a little
  13. Crossing loose gravel, how should your arms and wrists be?

    1. Resting on the tank for balance
    2. Locked straight, so the front wheel stays rigid
    3. One hand off the bars for balance
    4. Loose, so the front wheel can move a little
  14. How should you ride after slowing for loose material?

    1. Close the throttle completely
    2. Open the throttle quickly
    3. Hold an even, steady throttle
    4. Pump the throttle on and off
  15. You cannot avoid a stretch of broken pavement. What should you do?

    1. Speed up and lean into the bumps to get across them faster
    2. Brake hard on the worst part
    3. Slow down and keep the bike as upright as possible
    4. Weave to find smoother spots
  16. Which wet surfaces should a motorcyclist watch for?

    1. Manhole covers, bridge gratings and lane markings
    2. Brick crosswalks on sunny days only
    3. Dry gravel driveways and dirt lanes
    4. Fresh asphalt and new concrete in the summer months

Obstacles and road surfaces: key rules to remember

Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗

Obstacles

  • Sudden obstacle: reduce speed, counter-steer, move to the safest side, stay in your own lane.
  • If you must ride over it: meet it head-on, slow down, stand slightly on the footpegs with knees flexed, and lighten the front wheel by leaning back slightly and accelerating a little as you reach it.

Rough surfaces

  • Avoid bumps, broken pavement and potholes when you can; otherwise keep the bike as upright as possible, slow down, and stand on the footpegs to absorb the shock.

Slippery surfaces

  • Watch for wet pavement just after rain starts, oil slicks in the centre of the lane, wet metal such as manhole covers and bridge gratings, and wet lane markings.
  • Snow and ice should be avoided completely.
  • If you must ride on a slippery surface: slow down, use both brakes smoothly and gradually, avoid sudden moves, and shift to a lower gear for traction, releasing the clutch gradually.

Loose material on surfaces

  • Sand, gravel, mud or leaves on pavement can be even more dangerous than wet pavement.
  • Approaching loose material: slow down, grip firmly, rise slightly off the seat and move slightly back for traction, keep arms and wrists loose so the front wheel can move a little, keep feet on the pegs, and hold a steady throttle once slowed.

Grated surfaces and railway crossings

  • On grated bridge decks the bike tends to vibrate and wander; this is usually not dangerous, so do not fight it.
  • Keep a steady speed and ride straight across, standing slightly with knees flexed, arms relaxed, firm grip, head up.
  • You do not need to cross railway tracks at a full 90 degrees; with other traffic around, 45 degrees or more is enough and avoids swerving.
