What is the significance of the center lane on a one-way street?

The center lane on a one-way street is often designated for turns only, which serves a significant purpose in traffic flow and safety. This lane allows vehicles to prepare for turns without obstructing the travel lanes used for through traffic, reducing congestion and the potential for accidents. By providing a dedicated space for vehicles to merge into when turning left or right, this lane facilitates smoother transitions at intersections and enhances the overall efficiency of the roadway.

Understanding the function of the center lane can help drivers navigate one-way streets more effectively, allowing them to position themselves appropriately for turns while ensuring that they do not impede the flow of straight-moving traffic. This setup ultimately contributes to safer driving conditions for all road users. Other options, such as reserving the lane for parking or bicycles, do not accurately reflect the primary role of the center lane in a one-way street configuration, as these would conflict with the need for vehicles to turn safely. Keeping the lane clear at all times is important, but it is more about ensuring efficient use for intended turning purposes rather than it being restricted from parking or bicycle use.
