記得第一次坐車走高速的時(shí)候就發(fā)現(xiàn)，在高速路的兩側(cè)設(shè)置著一種指示燈似的標(biāo)識，那時(shí)候除了在高速公路上“飛馳”的興奮感之外，更多的是對這種設(shè)施的好奇。后來專門了解了下，才知道，那是專門用來顯示道路邊界輪廓、指引車輛正常行駛而且具有逆反射性能的一種交通安全設(shè)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.

我們都知道在高速公路上，每輛車的行駛速度都是飛快的，而在夜間行駛的時(shí)候如果沒有一定的線路指示，告訴行駛的汽車是非常危險(xiǎn)的，而輪廓標(biāo)的使用可以為夜間行駛的汽車提高安全度，其可以通過對汽車燈光的反射，使得司機(jī)可以很快的了解到前方的道路狀況，可以很好的保證通車安全。

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.

您經(jīng)常駕駛在高速公路上嗎？有沒有為自己的行車安全擔(dān)心過呢？有了輪廓標(biāo)，讓您的出行更加的安全！

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