What does the sawtooth marking at an intersection mean?
2 Answers
Intersection sawtooth markings indicate tidal flow lanes. Here are the relevant details: 1. Peak hours: These are primarily implemented for sections where traffic concentrates during certain peak periods but has insufficient lanes, or where there's significant difference in bidirectional traffic flow during morning/evening rush hours. When encountering such lanes, simply follow the variable lane indicators. 2. Variable lanes: Generally, the travel direction of variable lanes adjusts according to time or traffic volume. When unsure, drivers should observe LED signals or directional signs and comply accordingly. Simply put: when displaying a straight arrow, proceed straight only; when showing a left-turn arrow, turn left; when indicating a right-turn arrow, turn right. 3. According to provisions in the "Road Traffic Safety Law": vehicles must obey intersection markings and signal regulations. Violations may constitute prohibited marking infractions, punishable by a 100-yuan fine and 3 penalty points.
I've been driving for over a decade and encountering sawtooth markings at intersections is a common occurrence. These are those jagged markings on the road surface, typically installed at crossings or school zones, designed to force drivers to slow down. It's such a clever design—the uneven surface causes the car to vibrate, with the steering wheel slightly shaking, reminding you not to rush through. Why is it important? Pedestrians or cyclists often appear suddenly at intersections. I've personally witnessed instances where drivers didn't slow down and nearly caused accidents. When slowing down, it's best to reduce your speed to 20-30 km/h. This not only ensures safety but also minimizes wear and tear on your tires and suspension system. In daily driving, developing the habit of braking when you see sawtooth markings can literally save your life. Plus, it's not worth getting fined for speeding—the relevant regulations are strict, and with more cameras around these days, reckless driving will just earn you demerit points.
