What is the meaning of the jagged white solid line on the road?
2 Answers
Road jagged white solid line is a variable guide lane line. The following is a specific introduction to the variable guide lane: 1. Setting section: The variable guide lane line means that there is more than one driving direction after entering the lane, and it is set in a relatively complex traffic section. It usually appears in the left lane or the right lane, and is generally combined with straight and right turns into one lane or left turns and U-turns into one lane. 2. Precautions: Overtaking, pressing the line, changing lanes, and even U-turns and reversing are not allowed in the variable guide lane line. When you need to enter the variable guide lane, you should check the traffic lights in advance. You can only enter when the light is green, and you cannot enter when the light is red. Sometimes the variable guide lane is not open all day. Pay attention to the signs above or on both sides of the road to avoid entering the variable guide lane by mistake and violating the rules, which may result in penalties.
I've been driving for over a decade and often see those zigzag white solid lines on urban roads. They're actually special markings indicating variable directional lanes. This means during specific time periods, the lane direction can change - for example, becoming left-turn or right-turn only during rush hours, while allowing straight-through traffic at other times. When I first encountered it, I was genuinely confused, but later realized that when coordinated with adjacent traffic lights or electronic signs, it significantly improves intersection throughput and reduces congestion. My advice for new drivers is to stay calm, wait for clear signals before changing lanes, otherwise entering the wrong direction could lead to penalties or collisions. Moreover, smart traffic systems are increasingly adopting this design nowadays, so downloading a navigation app to check traffic conditions in advance is quite practical. In short, paying attention to these markings during daily driving can save you both time and hassle.
