What does a solid white line on the road indicate?

A solid white line on the road serves to indicate that lane changes are discouraged or prohibited. This is important for maintaining safety on the roadway, as the solid line signals drivers to remain in their current lane to avoid potential conflicts or accidents. It is often used in situations where changing lanes could be particularly dangerous, such as at exit ramps, where traffic is merging or diverging.

While a dashed white line would allow for lane changes, a solid line maintains the flow of traffic and helps reduce risks associated with erratic lane shifting. This can be especially critical in heavy traffic scenarios or when visibility is limited. Knowing this distinction is essential for safe driving practices and adhering to road rules.
