When you need to change lanes, it is important to:
- Signal your intentions ahead of the lane change.
- Check your blind spot.
- Make sure the lane is clear before entering.
- All of the above. ✓
Answer: D. All of the above.
When you change lanes, all three habits matter: signal ahead of time, check your blind spot, and confirm the lane is clear before you move over.
Why this is the answer
The handbook treats a lane change as a sequence you complete before the car moves sideways. It says you must activate your signal before moving into the left lane so other drivers know what you are about to do. It also explains that blind spots sit near the left and right rear corners where mirrors and peripheral vision do not reach, and that you turn your head to make sure those areas are clear before changing lanes or passing. Before pulling out, you also confirm you have time and room, meaning the space you want is open.
Why the other answers are wrong
- A. Signal your intentions ahead of the lane change. — Signaling alone is not enough because the handbook also requires you to turn your head and check that the space is open before moving over.
- B. Check your blind spot. — Checking the blind spot is only one step; the handbook also expects a signal beforehand and a check that the lane itself is clear.
- C. Make sure the lane is clear before entering. — Seeing that the lane is clear does not remove the need to signal your intention and to look into the blind spot areas first.
Remember it
Think of it as a three-beat routine before the wheel moves: signal, turn your head, then take the space.
