(1) No person shall drive a motor vehicle on any highway at such a slow speed as to impede or block the normal and reasonable forward movement of traffic, except when a reduced speed is necessary for safe operation of such vehicle or in compliance with law.
(2) Whenever the department of transportation or local authorities within their respective jurisdictions determine, on the basis of an engineering and traffic investigation as described in the state traffic control manual, that slow speeds on any part of a highway consistently impede the normal and reasonable movement of traffic, said department or such local authority may determine and declare a minimum speed limit below which no person shall drive a vehicle, except when necessary for safe operation or in compliance with law.
(3) Notwithstanding any minimum speed that may be authorized and posted pursuant to this section, if any person drives a motor vehicle on a highway outside an incorporated area or on any controlled-access highway at a speed less than the normal and reasonable speed of traffic under the conditions then and there existing and by so driving at such slower speed impedes or retards the normal and reasonable movement of vehicular traffic following immediately behind, then such driver shall:
(a) Where the width of the traveled way permits, drive in the right-hand lane available to traffic or on the extreme right side of the roadway consistent with the provisions of section 42-4- 1001 (2) until such impeded traffic has passed by; or
(b) Pull off the roadway at the first available place where such movement can safely and lawfully be made until such impeded traffic has passed by.
(4) Wherever special uphill traffic lanes or roadside turnouts are provided and posted, drivers of all vehicles proceeding at less than the normal and reasonable speed of traffic shall use such lanes or turnouts to allow other vehicles to pass or maintain normal traffic flow.
(5) Any person who violates any provision of this section commits a class A traffic infraction.
