The Keep Right Except To Pass sign MUTCD R4-16 indicates that drivers should keep to the right-hand lane of a multi-lane roadway unless they are passing slower-moving vehicles or making a left-hand turn; this helps to improve traffic flow and reduce congestion, particularly on highways and interstates with high volumes of traffic.
