Never change lanes without…?
- Checking the rear view mirror
- Signaling and decreasing speed
- Signaling, checking the rear view mirror and checking blind spots ✓
- Blowing your horn and providing the appropriate hand signal
Answer: C. Signaling, checking the rear view mirror and checking blind spots
Never change lanes without signaling, checking your rear view mirror and checking your blind spots.
Why this is the answer
The handbook sets out the steps for a lane change: check your mirrors for a safe space, look over your shoulder into the blind spot (watching for bicycles and small vehicles), then signal. It also says never to change lanes without giving the proper signal and looking to make sure the move can be made safely. That combines signaling with mirror checks and blind-spot checks, which is what the correct choice describes. The handbook points out that side mirrors show only narrow views, so a shoulder check is the only way to confirm nothing is in your blind spot.
Why the other answers are wrong
- A. Checking the rear view mirror — Checking the mirror alone leaves out the signal and the shoulder check into the blind spot, which the handbook also requires.
- B. Signaling and decreasing speed — Signaling and slowing down is not the procedure the handbook gives; you need to check mirrors and blind spots, and slowing is not part of a lane change.
- D. Blowing your horn and providing the appropriate hand signal — Honking and hand signals are not part of changing lanes, and a hand signal does not replace the signal, mirror check and blind-spot check.
Remember it
Mirror, shoulder, signal, then look again: the blind spot is where bicycles hide, so turn your head before you move.
