What Does a Sawtooth Lane Mean?

[DelAriana]

Sawtooth lane is a variable lane that reminds drivers of the driving direction in variable lanes. Below are the specific details about sawtooth lane markings: 1. 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 deceleration is required. These markings come in single-dashed, double-dashed, or triple-dashed forms and are perpendicular to the direction of travel. Vertical deceleration markings for lanes consist of a series of diamond-shaped dashed lines parallel to the lane dividing lines. 2. Sawtooth lane markings are usually installed at bridge approaches, exits, or turns. Their primary function is to create a visual narrowing effect that induces a sense of pressure, prompting drivers to automatically reduce speed at locations requiring deceleration, such as curves or slopes. Regarding lane changes under deceleration markings, the key factor is the state of the adjacent markings. If the adjacent marking is a solid line, lane changes are prohibited; if it's a dashed line, lane changes are permitted.
