Stop bars should be used to indicate the point behind which vehicles are required to stop in compliance with a traffic control device. Stop bars should not be used without an accompanying traffic control device, i.e. a stop sign or a traffic signal.
Signalized intersections
The placement of stop bars at all signalized intersections requires coordination with the Signal Design Unit. The station of the stop bars and the quantity shall be shown in the Pavement Marking Plans.
Unsignalized intersections
The placement of stop bars at all unsignalized intersections shall be located per RSD 1205.04 and shown on the Pavement Marking plans. On all sheets with stop bars at unsignalized intersections include the note “ENGINEER TO APPROVE LOCATION OF ALL UNSIGNALIZED STOP BARS." on the plans.
The following list is intended to provide guidance on the use of stop bars for various unsignalized locations. The use or non-use of stop bars is pending NCDOT approval.
