问:停车让行线的作用及表示形式是什么? 答:停车让行线的作用是指示行驶中的车辆在路口遇有此线及“停”字时,必须停车,让干道车辆先行。此线与“停车让行”标志配合使用。停车让行线由两条平行白色实线和一个“停”字组成,在双向行驶的路口,其长度应与车行道中心线连接;在单向行驶的路口,其长度应横跨整个路面,如图17所示。 Q: What is the effect of parking and how to express it? A: The purpose of parking is to instruct vehicles in transit to meet this line and “stop” at the intersection. They must stop and let the trunk vehicles go first. This line is used in conjunction with the “stop and go” symbol. The stopping line consists of two parallel white solid lines and one “stop” character. At the two-way intersection, its length should be connected with the center line of the roadway. At unidirectional intersection, the length of the line should extend across the entire road surface , As shown in Figure 17.
