What is the lane with serrated edges on both sides called?
1 Answers
The lane with serrated edges on both sides is called a 'variable lane'. Typically, there are zigzag diagonal lines on both sides of the lane. Traffic authorities adjust the direction of the variable lane based on road traffic conditions, usually switching between straight and turning directions to maximize lane utilization and alleviate traffic congestion. Above the serrated lane, there is usually a directional sign, or corresponding variable lane signs on both sides of the road, reminding drivers to pay attention to the current direction of the variable lane. After entering the variable lane, drivers must follow the directions indicated by the overhead signs. Generally, when there is heavier traffic in the left lane, it will switch to a left-turn lane, and similarly, the right lane will switch to a right-turn lane when traffic is heavier on that side. On both sides of the road, there are usually posted time periods indicating the direction of the serrated lane. The direction of the serrated lane varies at different times, and entry is prohibited during other periods. Particularly during morning and evening rush hours, the direction of the serrated lane may be reversed. Before entering the lane, drivers must confirm the current direction; otherwise, they risk driving against traffic, which can result in fines, penalty points, traffic congestion, and compromised road safety.
