What is the lane with short white diagonal lines on both sides?
1 Answers
The lane with short white diagonal lines on both sides is called a sawtooth lane. Here are the specific details about sawtooth lane markings: 1. Appearance: Sawtooth lane markings are a type of deceleration marking. Deceleration markings can be divided into horizontal deceleration markings and vertical deceleration markings. They are white dashed lines set up in toll plaza areas, exit ramps, or other sections where vehicle speed reduction is required. They come in forms such as single dashed lines, double dashed lines, and triple dashed lines, arranged perpendicular to the direction of travel. The vertical deceleration markings for the lane consist of a series of diamond-shaped dashed lines parallel to the lane dividing line. 2. Function: Sawtooth lane markings are typically installed at bridge approaches, exits, and turns. Their main purpose is to create a visual narrowing of the lane, inducing a sense of pressure on drivers, prompting them to automatically reduce speed at locations requiring deceleration, such as curves and slopes. Whether lane changes are permitted under deceleration markings depends on the state of the adjacent markings. If the adjacent line is solid, lane changes are not allowed; if it is dashed, lane changes are permitted.
