What kind of lines separate adjacent lanes of traffic moving in the same direction?

Lane lines are the appropriate type of markings that separate adjacent lanes of traffic moving in the same direction. They serve a crucial purpose by clearly delineating different lanes for vehicles, helping to guide drivers and maintain order on the roadway. These lines are typically painted in a solid or dashed white color, signaling to drivers where they can safely change lanes or need to stay within their designated lane.

In contrast, center lines are used to separate traffic moving in opposite directions, while edge lines mark the boundary of the roadway, indicating the limits of driving space for vehicles. Barrier lines typically indicate areas where crossing is prohibited, such as at ramps or other restricted zones. Each type of line serves a specific function within traffic management, but lane lines are essential for facilitating organized movement within lanes traveling in the same direction.
