What indicates the left edge of traffic lanes on a divided highway going in your direction?

A solid or broken yellow line indicates the left edge of traffic lanes on a divided highway going in your direction. This is important for drivers as it helps in maintaining awareness of lane boundaries and division between opposing traffic flows.

The solid yellow line signals that passing is not permitted from your lane, while the broken yellow line indicates that passing is allowed. Together, they provide essential guidance regarding safe driving practices within that area. These markings ensure that drivers are aware of their positioning on the road and can make informed decisions while navigating the highway. Understanding these markings contributes significantly to road safety and efficient traffic flow.
