What does a single solid white line across an intersection mean?

A single solid white line across an intersection indicates that drivers should stop behind the line for a traffic sign or signal. This marking serves as a guideline to enhance safety and order in traffic flow. It clearly defines the stopping point for vehicles, making it essential for drivers to halt before crossing that line unless directed otherwise by a traffic signal.

This practice helps ensure that vehicles do not encroach upon pedestrian crosswalks or interfere with the orderly flow of traffic, contributing to overall road safety. By stopping behind the line, drivers also have a clear view of oncoming traffic and any pedestrians that may be crossing, further promoting safety for everyone on the road.
