What does a solid white line indicate near intersections?

Answer: B — It helps prevent lane changes

A solid white line near intersections primarily serves to help prevent lane changes. This line indicates that changing lanes is discouraged or not permitted due to the proximity to an intersection. It promotes safe driving behavior by encouraging drivers to remain in their designated lanes as they approach intersections, reducing the potential for accidents caused by sudden lane changes. The presence of a solid white line provides clarity on where drivers should position their vehicles, making it easier for everyone on the road to anticipate movements and respond appropriately. This is crucial for maintaining the flow of traffic and ensuring that all road users, including pedestrians and cyclists, can navigate intersections safely. The other options, such as indicating no stopping, allowing for merging, or designating a bike lane, do not accurately describe the primary function of a solid white line at intersections. These lines are meant to create boundaries for vehicle travel and enhance safety, not to facilitate stopping or merging maneuvers.
