What are the usage rules for variable lanes?
1 Answers
Variable lanes are used according to their changing directions. Vehicles entering a variable lane must follow the direction indicated by the signage. The direction of a variable lane is determined by traffic flow—when left-turn traffic is heavy, the variable lane will switch to left-turn mode to alleviate pressure, and similarly, it will switch to right-turn mode when right-turn traffic is heavy. Once the lane changes to a turn-only direction, straight-through driving is no longer allowed, as the lane typically alternates between turning and straight-through directions. This type of lane is primarily designed for sections where traffic is concentrated during peak hours but lanes are insufficient, or where traffic flow differs significantly between morning and evening rush hours. Based on the characteristics of traffic flow during different periods, the direction is flexibly adjusted to alleviate congestion. Once a vehicle enters a variable lane, it must follow the direction indicated by the overhead signage. After entering a variable lane, drivers must not cross the line to change lanes, as this may result in a fine and a 3-point penalty if caught by electronic enforcement. Vehicles in a variable lane are also prohibited from making U-turns or speeding, which may likewise lead to fines and a 3-point penalty. The direction of the variable lane will not change if there are vehicles within 100 meters of the stop line. Violations occur only when drivers fail to follow the required direction—for example, driving straight when the lane is marked for left turns will definitely result in a penalty.
