The sawtooth lines on the road represent a variable lane. Below are the meaning and precautions regarding sawtooth lines on the road: Meaning of sawtooth lines on the road: Sawtooth lines indicate a variable lane, which looks distinctly different from other lanes. Generally, it appears similar but has many diagonal lines inside the lane, resembling sawteeth. This lane can change its direction based on the current traffic flow—allowing straight, left, or right turns. Essentially, this lane can adjust its direction according to traffic conditions, but there are time restrictions, meaning drivers cannot freely choose the direction at any time. Precautions for sawtooth lines on the road: Whether dashed or solid, these lines remind drivers to slow down. However, the key difference is that when the sawtooth line is solid, lane changes are strictly prohibited, whereas dashed lines permit lane changes. In most cases, sawtooth lines encountered are solid, often found on highways to remind vehicles to reduce speed.

When I see those zigzag lines on the road, I always remind myself to slow down. They are designed to warn drivers to reduce speed, especially near pedestrian crossings or schools. I remember once driving too fast past a school and almost hitting a child, so now I take it very seriously. These lines enhance visual impact with their jagged shape, making people instinctively slow down, especially when they reflect more prominently in the rain. They are installed in many urban areas to reduce accident rates and protect pedestrians crossing the street. Slowing down while driving not only avoids fines but also makes the streets safer. Personally, I think everyone should develop the habit of gently pressing the brakes when they see them, rather than regretting it after an accident occurs.

When I first started driving, I didn't understand the purpose of those zigzag lines, but my instructor said they indicate the need to slow down because pedestrians might suddenly appear. Later, I noticed that zigzag lines are usually present before pedestrian crossings or intersections. If you don't slow down, you could be fined by the police or hit someone. I think it's very useful for new drivers because the design is eye-catching and reminds you to adjust your speed. On rainy days, I always slow down when driving over them, developing this habit to reduce risks. Now on the road, I always pay attention to these markings—they're like silent safety guides helping to avoid trouble. Learned from experience: disrespecting road markings can easily lead to trouble, so it's essential to stay cautious at all times.
