道路上的道口桩也叫警示桩，红白警示桩和黄黑警示桩的区别，道路上的警示桩常见的颜色有红白相间的，黄黑相间的，蓝白相间的，那么这几种颜色有什么区别，适合用在什么场所呢。我们在参考推广的一些信息里发现，这些颜色代表的意思是，黄黑两种色彩的警示桩主要是提醒人们不要占用道路，不要轻而易举的进入通道以外的地方，并且要特别注意。

Road crossing stakes, also known as warning stakes, distinguish between red and white warning stakes and yellow and black warning stakes. Common colors of warning stakes on roads include red and white, yellow and black, and blue and white. So, what are the differences between these colors and where are they suitable for use. We found in some reference promotion information that these colors represent that the yellow and black warning posts mainly remind people not to occupy the road, not to easily enter places outside the passage, and to pay special attention.

红白警示桩主要是使用在道口两侧，一般的每一侧用两个，红色和白色相间的条纹表示不能让人们走进有危险的地方，还有就是有消防设施以及消防通道的地方不能被阻拦。道路警示桩安装时应该放直，如果有装修用的水平尺要用它靠着。蓝白色的警示桩也是比较醒目的，用来提醒人们在进入区域之前就做好相应的准备，要眼观六路耳听八方。

Red and white warning posts are mainly used on both sides of the road crossing, with two on each side. The red and white stripes indicate that people cannot enter dangerous areas, and areas with fire protection facilities and fire exits cannot be obstructed. When installing road warning posts, they should be placed straight, and if there is a leveling rod used for decoration, it should be used to lean against them. The blue and white warning posts are also quite eye-catching, used to remind people to be prepared before entering the area, and to observe and listen in all directions.

黄黑颜色的警示桩安装好后就不要在移动了，红白颜色的警示桩的地方就算是停车也不行，也要找合适的位置，蓝白色的警示桩提醒人们要引起注意。所以一般来讲红白标识的是禁止，危险级别高。黄黑标识的是警告，危险级别中，蓝绿标识的是，危险级别低。纵向对比，还是使用红白警示桩的地方多一些，蓝白警示桩则要少一些。

After installing the yellow and black warning posts, do not move them anymore. Even if parking is not possible, it is important to find a suitable location for the red and white warning posts. Blue and white warning posts remind people to pay attention. So generally speaking, the red and white signs indicate prohibition, with a high level of danger. The yellow and black markings indicate warnings, while the blue and green markings indicate safety. The hazard level is low. In vertical comparison, there are more places where red and white warning posts are used, and fewer places where blue and white warning posts are used.
