What does a guide lane line mean?

[DiCharlie]

Guide lane lines are directional lane markings used to indicate the direction vehicles should follow when entering an intersection. These markings are typically painted at busy traffic intersections to clearly define driving directions, ensure orderly traffic flow, and alleviate congestion. Types and functions of guide lane lines: Guide lane lines are marked on the road surface of each lane and can be categorized into variable and fixed types. They usually appear at high-traffic intersections to guide vehicle direction, maintain orderly traffic flow, and reduce congestion. Fixed guide lane lines include straight lanes, left-turn lanes, and right-turn lanes, while variable guide lane lines include combined left-turn and U-turn lanes, combined right-turn and straight lanes, and tidal flow lanes. Rules for driving in variable guide lanes: Variable lanes are typically set as combined left-turn and U-turn lanes or combined right-turn and straight lanes. If the current lane direction is unclear, drivers can follow the flow of traffic. For example, if there are fewer left-turning vehicles than straight-moving vehicles, the variable lane may be designated for straight movement. For tidal flow lanes, drivers must follow the directional signs based on the time of day. For instance, during morning rush hours, the variable lane may be for straight movement, while during evening rush hours, it may switch to left turns. If a variable guide lane has no directional indicators or markings, drivers may change lanes to the left or right as needed.
