What is the purpose of the shared center lane on a roadway?

The shared center lane on a roadway is specifically designed for left turns from both directions. This lane allows vehicles traveling in opposite directions to safely make left turns without obstructing the flow of traffic in the main travel lanes. By using the shared center lane, drivers can position themselves appropriately for their turn while minimizing the risk of accidents that could occur if they were to attempt left turns directly from the travel lanes.

The design of this lane helps in organizing the traffic movement and provides a dedicated space where turning vehicles can wait without impeding through traffic. This is particularly beneficial in busy areas where left turns might otherwise lead to significant traffic backups. Understanding the purpose of shared center lanes is crucial for safe driving, as misuse of these lanes can lead to dangerous situations on the road.
