What is the purpose of the Two-way Left Turn Only sign?

The purpose of the Two-way Left Turn Only sign is to indicate that the center lane is specifically designated for vehicles that are making left turns. This is crucial for safety and traffic management, as it allows drivers from both directions to turn left without interfering with through traffic. This dedicated lane helps to prevent confusion and potential accidents by clearly marking where vehicles should position themselves when planning to turn left.

This sign is particularly helpful in situations where many vehicles may be traveling in both directions, providing a structured approach to left turns and enhancing overall traffic flow. In contrast to other traffic signs, this sign does not indicate parking regulations, merging areas, or one-way street designations, making its function unique and vital for safe driving practices.
