What is the meaning of the diamond-shaped dashed lines on the road?
4 Answers
The diamond-shaped dashed lines on the road indicate longitudinal deceleration markings for the traffic lane. Longitudinal deceleration markings consist of a series of diamond-shaped dashed lines parallel to the lane dividing lines. They are typically installed at bridge approaches, turns, and other locations where speed reduction is necessary. Their primary purpose is to create a visual narrowing effect, inducing a sense of pressure that prompts drivers to automatically slow down in areas requiring reduced speed, such as curves and slopes. Road traffic markings can be categorized into three types based on their placement: Longitudinal markings: Markings set along the direction of traffic flow. Transverse markings: Markings set at an angle to the direction of traffic flow. Other markings: Character markings or other forms of markings.
I've been driving for over ten years and often see those diamond-shaped dashed lines on urban roads. At first, I didn't quite understand their specific meaning. Later, I learned from a traffic lecture that these markings are mainly used to remind drivers that there is a pedestrian crossing or pedestrian crossing area not far ahead, meaning you should quickly slow down and pay attention. They are commonly seen near schools and shopping mall entrances. Their design gives drivers advance buffer time to avoid accidents. I've developed a habit of easing off the accelerator whenever I see them, reducing my speed to 20-30 kilometers per hour, and looking around more to see if there are any pedestrians preparing to cross. Especially on rainy days when the road is slippery and the markings reflect light easily, it's even more important to gently brake and slow down. In short, don't overlook these details; following them can significantly improve driving safety and reduce the risk of fines or accidents. Road markings are silent guardians—staying alert is key.
As a new driver, I was quite confused about the diamond-shaped dashed lines on the road when I first got my license. A friend told me that they indicate upcoming pedestrian crossings, meaning you must slow down and be prepared for pedestrians when approaching them. For example, they are commonly seen at community intersections. Whenever I spot them, I start gently applying the brakes to reduce speed. I remember one afternoon when I was in a hurry and forgot to slow down, I almost hit a child who suddenly ran out, which gave me a cold sweat. Since then, I've been more cautious. I advise all new drivers to pay attention to these markings, avoid driving too fast in daily commutes, and maintain a safe distance while slowing down to observe pedestrian movements. Safety first—don’t wait for an accident to regret it.
Having driven for decades, I'm very familiar with the meaning of diamond-shaped dashed lines on the road: they serve as a warning for an upcoming pedestrian crossing, requiring immediate speed reduction. These markings are typically placed about 50 meters before an intersection. Every time I approach them, I slow down to under 30 km/h while checking both sides for pedestrian movement. Safety comes first—never take chances.
