You are making a left turn at an intersection with a green light. There is a solid white line separating the turn lane from the adjacent through lane. What does this solid white line indicate?
- AIt indicates a preferential lane for high-occupancy vehicles during peak hours.
- BIt marks the point beyond which you cannot change your mind about the turn.
- CYou should not cross this line, as it discourages lane changes within the intersection.
- DYou must stay within your lane during the entire turn, as it is a protected turn.
Show answer & explanationAnswer & explanation
Correct answer: C. You should not cross this line, as it discourages lane changes within the intersection.
A solid white line indicates that lane changes are discouraged or prohibited. In the context of a turn lane at an intersection, it means you should not change lanes once you are in that turn lane.
Why the other options are wrong
- A. Preferential lanes are typically marked with diamond symbols and specific signage, not just a solid white line.
- B. While it's wise to commit to your turn, the line's primary meaning is about lane changes, not decision points.
- D. A solid white line does not necessarily mean a protected turn; a green arrow indicates a protected turn.
Solid White Line (Lane Marking)
A solid white line on the roadway indicates that lane changes are discouraged or prohibited, particularly where it would be hazardous.
- Discourages lane changes.
- Often found near intersections, on ramps/off ramps, and tunnels.
- Separates traffic flowing in the same direction.
Memory trick: White lines are like walls, solid means stay put, broken means you can peek and move.
