North Carolina General Statutes Chapter 136. Transportation § 136-18.4. Provision and marking of “pull-off” areas

The Department of Transportation is hereby authorized and directed (i) to provide as needed within its right-of-way, adjacent to long sections of two-lane primary highway having a steep uphill grade or numerous curves, areas on which buses, trucks and other slow-moving vehicles can pull over so that faster moving traffic may proceed unimpeded and (ii) to erect appropriate and adequate signs along such sections of highway and at the pull-off areas. A driver of a truck, bus, or other slow-moving vehicle who fails to use an area so provided and thereby impedes faster moving traffic following his vehicle shall be guilty of a Class 3 misdemeanor.
