Zigzag road markings indicate lane diversion for vehicles. Here are the relevant details: 1. Function of zigzag road markings: Zigzag road markings are also known as variable direction lane markings. These are primarily implemented during peak hours when traffic is concentrated, but lanes are insufficient or when there is alternating heavy traffic flow during morning and evening rush hours. 2. Driving rules for variable direction lanes: When encountering such lanes, drivers should follow the variable lane indicators. There are time restrictions—drivers cannot freely choose the direction of travel at any time. These markings appear as zigzag white solid lines between lanes in variable direction lanes. 3. Difference between variable direction lanes and regular lanes: These lanes offer flexibility unlike conventional lane markings. Regular lanes strictly follow their designated directions (straight or turn), whereas variable direction lanes are typically installed in areas with complex traffic conditions.

On my daily commute to work, I often notice those zigzag road markings, the small patterns shaped like waves or fish bones. At first, I thought they were just decorative elements to beautify the road surface. Later, I learned from a traffic police friend that these are actually warning markings designed to remind drivers to slow down. They are typically installed in accident-prone areas, such as near schools, intersections, or in front of speed bumps. These markings create a visual impact that subconsciously prompts drivers to reduce speed, proving especially effective during rainy or foggy conditions when visibility is poor. I remember last year when these markings were added at the entrance of my residential area, vehicle speeds dropped significantly, and the accident rate was cut in half. Now, children crossing the street are much safer. If you frequently drive on highways or urban roads, don’t ignore these markings—forcing your way through could damage your chassis or lead to rear-end collisions, causing serious trouble.

As a veteran driver with thirty years of experience, I see sawtooth road markings as the guardian angels of traffic. When they appear on the road, they often indicate speed bumps or hazardous areas ahead, such as sharp turns or downhill sections, aiming to ensure vehicles pass smoothly and avoid skidding. From my experience, I've learned that driving isn't just about speed—paying attention to these details is crucial: their reflective coatings enhance visibility at night, helping reduce speeding risks. Reflecting on past highway accidents before these markings existed, I truly appreciate the progress in road safety today. The key is to develop a habit of slowing down, protecting both yourself and pedestrians—this isn't just about obeying traffic rules but also a reflection of daily responsibility.

I've always been fascinated by road design, especially those sawtooth road markings. They use highly reflective materials with a wavy surface treatment, scientifically designed to increase visual disturbance for drivers, prompting them to subconsciously slow down. Simply put, they're not ordinary lines but a warning system specifically engineered for human visual response, placed several meters before speed-reducing facilities as an alert. In practical application, engineers fine-tune the angles based on road conditions to prevent tire wear. I think this kind of small innovation is pretty cool—from materials to shape, it embodies safety concepts. Next time you're driving, pay more attention to them.
