Which of the following are used on some highways to direct drivers into the proper lanes for turning?
- Flashing red lights
- Flashing yellow lights
- White lines on the side of the road
- White arrows in the middle of the lanes ✓
Answer: D. White arrows in the middle of the lanes
White arrows painted in the middle of the lanes are used on some highways to steer drivers into the correct lane for turning.
Why this is the answer
The handbook's pavement markings section explains that turn lanes often have arrows painted in them, used together with the white lane lines, so you can tell which turn is allowed from that lane. A painted arrow sits in the lane itself and points the way the lane goes, which is exactly what directs you into the right lane before a turn. The passages describe these arrows as pavement markings that work with the lane lines, not as signals or edge markings.
Why the other answers are wrong
- A. Flashing red lights — Flashing red lights are not described in the passages as lane-direction markings; the red arrow rules in the handbook are about traffic signals, not painted lane guides.
- B. Flashing yellow lights — Flashing yellow lights are not mentioned in the passages as a way to sort drivers into turn lanes.
- C. White lines on the side of the road — White lines along the side of the road mark the road edge or crosswalks in the passages, and they do not tell you which turn a lane allows.
Remember it
Think of the arrow as a painted instruction sitting in the lane: it points where that lane can take you.
