Motorcyclists have the same rights and responsibilities as other road users. Motorcycles are smaller and harder to see, easily hidden in blind spots, and it's hard to judge how far away or how fast they are. About half of all motorcycle crashes involve another motor vehicle.

Know the rule

Left turns: cars turning left in front of an oncoming motorcycle cause serious crashes. Look, then look again, and know the motorcycle's speed before you turn.

Know the rule

Turn signals: most motorcycle signals don't cancel automatically. Before turning in front of one that's signaling, make sure it's really turning.

Handbook p. 103 ↗

Know the rule

Lanes: a motorcycle is entitled to a full lane. Never move into the same lane alongside one, even if the lane is wide and the rider is to one side.

Handbook p. 103 ↗

Know the rule

Riders keep changing position within the lane to see, be seen, and avoid objects.

Handbook p. 103 ↗

Know the rule

Bad weather and slick surfaces are serious problems for motorcycles; leave even more following room in rain or on slick roads.

Handbook p. 104 ↗

Road surfaces that can force a rider to change speed or direction:

  • Gravel and debris
  • Pavement seams
  • Small animals
  • Manhole covers
Handbook p. 104 ↗

Know the rule

Always check mirrors and blind spots for motorcycles before entering or leaving a lane or intersection, and use your signals and brake lights so riders can anticipate you.

More than 3 seconds

Following distance to leave behind a motorcycle

Handbook p. 104 ↗

Put it into practice

You're waiting to turn left and see a single headlight approaching. Look again to judge its speed; motorcycles are easy to misjudge. Wait until you're sure you can turn without cutting in front of it.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

Motorcycles are easily hidden in a car's:
  1. turn signal glare
  2. high beams
  3. blind spot
  4. side mirror reflection

Answer: blind spot

Motorcycles' small size lets them disappear into blind spots.

Handbook p. 103 ↗
A common cause of serious crashes involving motorcycles is:
  1. motorcycles passing on the right
  2. cars merging behind motorcycles
  3. motorcycles tailgating cars
  4. cars turning left in front of an oncoming motorcycle

Answer: cars turning left in front of an oncoming motorcycle

Left turns in front of oncoming motorcycles are a major crash cause.

Handbook p. 103 ↗
Motorcycle riders may forget to switch off their turn signal, so before turning in front of one you should:
  1. make sure it is really turning
  2. flash your headlights to warn them
  3. assume the signal is accurate and proceed
  4. honk to get their attention

Answer: make sure it is really turning

Verify the motorcycle is really turning before you act on its signal.

Motorcycles get the same full lane width as any other vehicle.
