When making a left turn, you should not:
- Signal to other drivers.
- Cut the corner. ✓
- Slow down.
- Move to the center or far left lane.
Answer: B. Cut the corner.
When making a left turn, you should not cut the corner.
Why this is the answer
The handbook's left-turn steps say to signal early, move into the center lane, slow down at least 100 feet from the corner, and look in all directions. It then says you should stay to the right of the center line as you enter the intersection and finish the turn by entering the lane that interferes least with other traffic. Swinging early and cutting across the corner works against that path, so it is the thing not to do.
Why the other answers are wrong
- A. Signal to other drivers. — Signaling is exactly what the handbook tells you to do well ahead of the turning point, so it is not something to avoid.
- C. Slow down. — Slowing down is required, since the handbook says to slow at least 100 feet from the corner.
- D. Move to the center or far left lane. — Moving into the center lane is a listed step for a left turn, so it is a proper action rather than a mistake.
Remember it
Think of the turn as a wide arc from the center lane: set up early, then stay right of the center line instead of clipping the corner.
