What is the purpose of medium lanes?

Medium lanes are designed to facilitate the safe and efficient movement of vehicles by providing a dedicated space for certain types of traffic, such as turning vehicles or those merging into main lanes. They help reduce congestion and improve traffic flow by separating different vehicle movements. Additionally, medium lanes can enhance safety by minimizing the risk of collisions between vehicles traveling in opposite directions or making turns. Overall, their purpose is to optimize road usage and improve the overall driving experience.
