Where does the centerline start and stop at an intersection?
The centerline markings should end where the stop bar would go if one was used. In no case should the line be more than 30 feet nor less than 4 feet from the nearest edge of an intersecting roadway.
Section 3B.16 Stop and Yield Lines notes that the minimum distance between a cross walk and the stop bar should be at least 4 feet except at roundabouts and mid-block crossings.
