What is the purpose of a turn lane?

The purpose of a turn lane is to allow vehicles to safely prepare to make a turn without obstructing the flow of through traffic. This dedicated lane helps improve traffic flow by providing a space where vehicles can slow down and position themselves for a turn without interfering with other vehicles that are traveling straight. By having a turn lane, drivers can execute their maneuvers more smoothly and safely, reducing the likelihood of accidents and traffic congestion at intersections. The design of turn lanes specifically aims to enhance overall roadway safety and efficiency.
