Answer: A. Signaling, checking the rear view mirror and checking blind spots
Never change lanes without signaling, checking the rear-view mirror, and checking your blind spots.
Why this is the answer
The handbook says to use your side-view mirrors whenever you plan to change your road position or direction. It also explains that mirrors still leave blind spots, especially to the side, so those areas need to be checked too. It advises looking in the rear-view mirror before you slow or stop. The provided pages do not separately state the signaling part, so that part is supported by the question's answer rather than these passages.
Why the other answers are wrong
- B. Blowing your horn and providing the appropriate hand signal — Honking and giving a hand signal are not described in the passages as the checks needed before a lane change; the handbook points to mirror and blind-spot observation.
- C. Signaling and decreasing speed — Signaling and slowing down does not cover the need to check your mirrors and blind spots, which the handbook says are needed when changing road position.
- D. Checking the rear view mirror — Checking only the rear-view mirror is incomplete because the handbook says side-view mirrors and blind spots must also be checked before moving over.
Remember it
Before you move over, check the mirror and then the blind spot that mirror cannot show you.
