What type of lines are used to separate more than one lane of traffic moving in the same direction where crossing the line is not permitted?

The use of solid white lines is to indicate that crossing the line is not permitted, particularly in situations where multiple lanes of traffic are moving in the same direction. These lines serve as a visual cue to drivers that they should remain in their lane and not change lanes, which helps maintain orderly traffic flow and enhances safety on the road.

While broken or dashed white lines indicate that changing lanes is allowed, solid yellow lines denote that passing is not permitted in situations with opposing traffic, rather than focusing on movements within the same direction. Understanding the different meanings of these line types is crucial for ensuring compliance with traffic regulations and for safe driving practices.
