Before you leave a parking space which is parallel to the curb, you should:

  1. Sound your horn
  2. Turn on your four-way flasher
  3. Look for traffic by turning your head ✓
  4. Look for traffic by using your inside rear-view mirror

Answer: C. Look for traffic by turning your head

Before leaving a parallel parking space, look for traffic by turning your head.

Why this is the answer

The manual's parallel-parking steps tell you to turn your head and look over your right shoulder through the rear window for pedestrians, bicyclists, motorcyclists, and other vehicles. It also says to use the inside rear-view mirror, but as a supplement. In the Sharing the Road chapter, the manual warns not to depend only on mirrors when leaving a curb and directs you to turn your head to spot bicyclists, skaters, and scooter riders beside or approaching you. A head check is the reliable way to see traffic before you move out.

Why the other answers are wrong

Remember it

Mirrors are helpers, not the whole check—turn your head before you pull away from the curb.
