Which of the following is NOT a reason to cross a solid white line?

Crossing a solid white line is generally not allowed as it indicates that it is unsafe or illegal to change lanes or position on the roadway. The only exceptions to this rule usually involve scenarios where safety or law enforcement intervention is present.

In the case of needing to reach a bus stop, it is important to maintain safety by following the roadway markings. A solid white line serves as a guideline to prevent drivers from making such maneuvers that could impede traffic or pose safety risks. Therefore, reaching a bus stop by crossing a solid white line is not considered justifiable, as it disregards the safety protocol indicated by the line.

Conversely, crossing the line may be permissible under specific circumstances, such as when passing a slow-moving cyclist or horse, as long as it can be done safely and is necessary to ensure a clear path. Additionally, following directions from police or traffic wardens takes precedence over road markings, allowing for crossing the line when directed for the sake of traffic control or public safety.
