Show answer & explanationAnswer & explanation
Correct answer: A. Left turns by vehicles traveling in either direction.
This description matches a Two-Way Left-Turn Lane (TWLTL). It is specifically designed for vehicles traveling in either direction to make left turns, providing a safe area to wait without blocking through traffic.
Why the other options are wrong
- B. Regular traffic flows in designated through lanes, not in a TWLTL.
- C. Passing is prohibited in a TWLTL; passing lanes are typically marked differently, often with broken yellow lines on the left of your lane.
- D. Emergency vehicle lanes are typically marked with specific signage or are shoulders/hard shoulders.
Two-Way Left-Turn Lane (TWLTL)
A center lane marked by solid yellow lines on the outside and broken yellow lines on the inside, used by traffic from both directions to make left turns.
- Used for left turns only.
- Shared by both directions of traffic.
- Entering too early or using for through traffic is illegal.
Memory trick: Yellow lines broken inside, solid outside, means left turns, not a ride.
