记得次坐车走高速的时候就发现，在高速路的两侧设置着一种指示灯似的标识，那时候除了在高速公路上“飞驰”的兴奋感之外，更多的是对这种设施的好奇。后来专门了解了下，才知道，那是专门用来显示道路边界轮廓、指引车辆正常行驶而且具有逆反射性能的一种交通设施。

I remember the first time I took a car on the highway, I noticed that there were signs resembling indicator lights on both sides of the highway. At that time, besides the excitement of "speeding" on the highway, I was more curious about this facility. Later on, I learned that it was a traffic safety facility specifically designed to display road boundary contours, guide vehicles to drive normally, and has anti reflection performance.

我们都知道在高速公路上，每辆车的行驶速度都是飞快的，而在夜间行驶的时候如果没有一定的线路指示，告诉行驶的汽车是非常危险的，而轮廓标的使用可以为夜间行驶的汽车提高度，其可以通过对汽车灯光的反射，使得司机可以很快的了解到前方的道路状况，可以很好的保证通车。

We all know that on highways, every car travels at a very fast speed. However, if there is no clear route indication during nighttime driving, it can indicate that the car is very dangerous. The use of contour markers can improve the safety of night driving cars. By reflecting the car lights, drivers can quickly understand the road conditions ahead and ensure safe traffic.

您经常驾驶在高速公路上吗？有没有为自己的行车担心过呢？有了轮廓标，让您的出行更加的！

Do you often drive on highways? Have you ever worried about your driving safety? With contour markers, your travel is safer!
