What does the sawtooth white lane line mean?

This refers to a variable lane. Here are the relevant details: 1. Purpose of setting: This is mainly designed for sections where traffic is concentrated during peak hours but lanes are insufficient, or where there is a significant difference in traffic volume between morning and evening rush hours. 2. Specific situation: Generally, the driving direction of a variable lane will be adjusted according to time or traffic volume. When drivers are unsure which way to go, they can simply follow the instructions on the LED signal lights or signs. In simple terms, if it shows a straight lane, you can only go straight; if it shows a left-turn lane, then turn left; if it shows a right-turn lane, then turn right.
I remember that after driving for so many years, the zigzag white lane markings are a type of traffic sign indicating that parking is not allowed along the road edge. They are commonly seen on urban main roads or near bus stops, arranged like teeth to remind drivers to maintain a safe distance. A few years ago, I parked by the roadside to wait for someone and forgot about this rule, resulting in a ticket from the traffic police. Later, I learned that this design is intended to avoid congestion and ensure public right-of-way, especially during peak hours in the morning and evening, as it helps reduce accident rates. I advise everyone not to take chances when driving and seeing these markings—otherwise, you might face fines and wasted time. Additionally, in rainy or foggy weather, the zigzag pattern is more easily recognizable, effectively preventing parked vehicles from obstructing visibility and causing rear-end collisions.
