Which of the following actions can save a motorcycle rider's life when s/he wants to change lanes, position within a lane, or before turning off the roadway?

  1. A quick movement toward the other lane
  2. A quick shoulder check ✓
  3. Slowing down quickly
  4. A sudden gear change

Answer: B. A quick shoulder check

A quick shoulder check is the action that helps a rider see traffic hidden in blind spots before changing lanes, shifting position in a lane, or turning off the road.

Why this is the answer

The handbook explains that mirrors do not show the whole traffic picture and that each side of the motorcycle has a blind spot. It tells riders to turn their head and look over the shoulder before turning or changing lanes. That physical check lets you spot a vehicle or person your mirror missed, so you do not move into a space that is already occupied.

Why the other answers are wrong

Remember it

Mirrors leave blind spots, so turn your head before you commit.
