  1. ALeft turns by vehicles traveling in either direction.
  2. BRegular traffic flow in both directions.
  3. CPassing slower vehicles in either direction.
  4. DEmergency vehicles only.
Show answer & 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.
