What is the purpose of two-way left turn lane markings?

The purpose of two-way left turn lane markings is to designate a specific lane that allows drivers to safely make left turns from either direction without interfering with the flow of traffic. This center lane is meant for the exclusive use of vehicles that are preparing to make a left turn, facilitating easier and safer maneuvering in busy areas.

By using the center left turn lane, drivers can wait for oncoming traffic to clear before making their turn, which minimizes the risk of accidents that might occur if drivers attempted to turn directly from the travel lane. The center lane also helps prevent congestion by keeping turning vehicles separated from the flow of through traffic.

The other options do not accurately describe the function of the two-way left turn lane. For instance, it isn't intended to allow for passing vehicles, nor is it designated solely for making left turns without stopping, as drivers must still yield to oncoming traffic before turning. Additionally, the lane is not meant for lane splitting, which is a practice typically associated with motorcycles and not relevant in this context.
