Motorcycles, scooters, and mopeds are not easy to see; therefore, you should:

  1. Slow down when driving.
  2. Make constant visual checks. ✓
  3. Share a lane with a motorcycle.

Answer: B. Make constant visual checks.

Make constant visual checks, because motorcycles, scooters, and mopeds are small and easily hidden in your blind spots.

Why this is the answer

The handbook says motorcyclists have the same rights and responsibilities as other drivers, and that motorcycles are smaller and harder to see, so they can disappear in vehicle blind spots. Its guidance for sharing the road is to check for motorcycles and use your mirrors when changing lanes or entering a road. Doing that repeatedly is how you keep track of a vehicle that is easy to lose sight of, which is what the correct choice describes.

Why the other answers are wrong

Remember it

Small vehicles vanish in blind spots, so move your eyes and mirrors often instead of assuming a glance was enough.
