Why must you do a shoulder check before a lane change?

  1. Mirrors do not show your blind spots.
  2. It tells other drivers you will change lanes.
  3. It makes your car go faster.
  4. It is only a rule for highways.
Show answer

Correct answer: Mirrors do not show your blind spots.

You must do shoulder checks in addition to mirror checks. This lets you see the areas your mirrors cannot show.
