What is the meaning of the white markings on the road?

[ChaseAnn]

The meaning of the white markings on the road is that they are transverse deceleration markings for the carriageway. Deceleration markings can be divided into transverse deceleration markings and longitudinal deceleration markings, which are white dotted lines set up in toll plaza areas, exit ramps, or other sections where vehicle deceleration is required. Their forms include single dotted lines, double dotted lines, and triple dotted lines, set perpendicular to the direction of travel. Below is an introduction to the longitudinal deceleration markings for the carriageway: 1. Meaning: Longitudinal deceleration markings for the carriageway are a set of diamond-shaped dotted lines parallel to the carriageway boundary lines. They are usually set at bridge approaches, turns, etc. 2. Function: Their main purpose is to create a sense of visual narrowing of the lane, inducing drivers to automatically decelerate at curves, slopes, or other locations where deceleration is required. Under deceleration markings, whether lane changes are allowed depends on the state of the markings beside the deceleration lines. If they are solid lines, lane changes are not permitted; if they are dotted lines, lane changes are allowed.
