Stop bar marks where drivers must stop at intersections

A Gulfport traffic advisory posted on social media says the thick white line painted before a crosswalk or stop sign — known as a stop bar — marks the exact point where drivers must stop.

Stop bars are solid white pavement markings, typically 12 to 24 inches wide, placed at intersections, traffic signals and crosswalks to show where vehicles must halt, the advisory said. The markings keep vehicles out of crosswalks, protect pedestrians and, at signalized intersections, can help trigger traffic sensors.

The post cited Mississippi law to explain legal obligations for drivers, listing MS Code 63-3-309, which says when facing a red signal a driver must stop before the crosswalk or a clearly marked line; MS Code 63-3-313, which prohibits disobeying official traffic-control devices; and MS Code 63-3-901, which bars parking in intersections and within specified distances of crosswalks and stop signs or signals.

Traffic officials say stopping behind the line keeps crosswalks clear, improves safety and helps traffic flow. We will provide more information as it becomes available.
