What does the serrated line on the highway mean?

[LeLilliana]

Highway The serrated line on the highway is called a longitudinal deceleration marking. Here is the relevant content introduction: 1. Longitudinal deceleration marking: It is a set of diamond-shaped dashed lines parallel to the lane dividing line. It is generally set at bridge approaches and turning points. The main function of this serrated line is to create a sense of compression by visually narrowing the lane, prompting drivers to automatically slow down at curves, slopes, and other locations where deceleration is required. 2. Specific situation: When a vehicle passes through a section with longitudinal deceleration markings, the driver's subjective vision will perceive the lane as gradually narrowing, prompting them to take deceleration measures and proceed slowly. This can effectively prevent drivers from applying emergency brakes just before the stop line.
