What does a two-way left turn lane signify?

A two-way left turn lane is specifically designed to facilitate safe left turns for vehicles coming from both directions of the street. This lane allows vehicles to merge into it from either side of the roadway in order to prepare for a left turn without obstructing the flow of through traffic.

Using this lane helps prevent accidents because it keeps turning vehicles out of the main traffic lanes, reducing conflicts with vehicles that are going straight. When drivers see a two-way left turn lane, they can anticipate that other vehicles may be entering the lane from the opposite direction to make a left turn, enhancing safety for all road users.

The other options detail uses that do not align with the designated function of a two-way left turn lane. While the lane cannot be used solely for right turns, U-turns, or bicycles and pedestrians, its primary purpose is to provide a safe space for vehicles making left turns, which is accurately captured in the correct option.
