Question: 1 / 150

When can a solid white line be crossed?

When changing lanes is necessary

Only by traffic moving to or from the shoulder

A solid white line on the road typically indicates a boundary between lanes that should not be crossed unless absolutely necessary. The correct context for crossing a solid white line is when traffic is moving to or from the shoulder, as it provides a safe area for vehicles to stop, park, or pull over. This ensures safety on the road by keeping specific actions separate from the main flow of traffic.

In contrast, changing lanes or making turns when a solid white line is present can create confusion and increase the risk of accidents. Solid white lines are specifically used to signify areas where lane changes are discouraged, thereby maintaining orderly traffic flow. Hence, the right conditions for crossing a solid white line align with situations related to shoulder use rather than general lane changes or turns.
