What is the purpose of a solid yellow line?

A solid yellow line serves a crucial purpose in roadway marking by indicating that crossing the line is prohibited. This means that drivers should not pass another vehicle when a solid yellow line is present, as it represents a safety measure to prevent accidents, especially on roads with two-way traffic where visibility may be limited. The solid line helps maintain safety by guiding drivers in making safe decisions regarding passing maneuvers.

In other contexts, a solid yellow line is distinct from a broken line, which indicates that passing is permitted when safe to do so. Additionally, separating one-way traffic is typically denoted by specific markings or arrows rather than a solid yellow line. Pedestrian areas are marked differently, often with different colors and signage to enhance visibility and safety for pedestrians. Understanding these distinctions is essential for safe driving practices on the road.
