Final answer:
The pavement sign that separates two lanes, traveling in the same direction, is called a dividing line or centerline. It helps to maintain order and safety on the road by indicating where vehicles should position themselves.
Step-by-step explanation:
The pavement sign that separates two lanes, traveling in the same direction, is called a dividing line or centerline. This line helps to maintain order and safety on the road by indicating where vehicles should position themselves. It is typically a solid white line in the middle of the road.
For example, if you are driving on a two-lane road and you see a solid white line in the middle, it means that you should stay in your lane and not cross over into the opposite lane.
The purpose of the dividing line is to prevent head-on collisions and to direct the flow of traffic in a safe and organized manner.
