What is a "stop line" at an intersection?

A "stop line" at an intersection is a solid white line that indicates the precise location where vehicles are required to stop at traffic signals or stop signs. This line helps to ensure that drivers come to a complete stop in a designated area, promoting safety for all road users, including pedestrians. It serves as a clear visual cue that helps regulate traffic flow and ensures that vehicles do not encroach into crosswalks or into the intersection before it is safe to proceed. Understanding the function of the stop line is crucial for maintaining order and safety at intersections in a commercial vehicle operation context.
