单行道

单行道，反方向不许进入

单行道又称单行线、单程路，指一条所有车道都只能往一个方向行驶、不得逆行的道路。单行道和绿波控制带等交通管制措施结合以后可以极大的提高道路的通行速度。但是单行道也需要有时绕路，对不熟悉路线的驾驶员造成困难，故旁边有时会设路牌有助公众了解使用。

交通标志

方向指示标志

单行道的开端会设立方向指示标志（英语：Direction, position, or indication sign）来指示该单行道的行车方向，又或在三岔路口（英语：Three-way junction）设立方向指示标志来指示主车道的行车方向。

不准驶入标志

在车道的末端会设立不准驶入的禁止标志。
