What lane divide a highway?

A lane divider on a highway typically refers to a painted line or barrier that separates lanes of traffic moving in opposite directions. Common types of lane dividers include solid yellow lines, which indicate that passing is not allowed, and dashed lines, which permit lane changes. In some cases, physical barriers like concrete walls or metal guardrails serve as lane dividers to enhance safety. These dividers help organize traffic flow and reduce the risk of collisions.
