What is the meaning of the jagged white solid line on the road?
2 Answers
This white jagged solid line is a variable direction lane marking. Below is relevant information about variable direction lanes: 1. Lane requirements: A variable lane, marked with multiple diagonal lines inside the lane resembling a lying "non" character, can change its direction indication according to traffic flow as the name suggests. This is mainly designed for sections with concentrated traffic during peak hours but insufficient lanes, or roads with significant differences in traffic flow between morning and evening rush hours. 2. Operation method: When encountering such lanes, simply follow the instructions of the corresponding lane traffic light.
The sawtooth-shaped white solid line on the highway is the lane edge line. I noticed it the first time I drove, and my instructor said the zigzag design makes it easier for drivers to see the lane boundary, so don’t drive too close to avoid crossing it. Especially on highways, it reminds us to stay within the safe driving zone, which is particularly useful in rain or snow when visibility is poor. Personally, I use it to adjust my direction and avoid crossing the line or accidentally entering the emergency lane. After years of driving, I’ve found that these small details can prevent accidents. New drivers, don’t overlook them—practice more to develop good habits. In fact, there are various road markings like yellow dashed lines, but the sawtooth white solid line is specifically designed for safety and is super practical.
