Section 3364 - Minimum speed regulation(a) Impeding movement of traffic prohibited.--Except when reduced speed is necessary for safe operation or in compliance with law, no person shall drive a motor vehicle at such a slow speed as to impede the normal and reasonable movement of traffic.(b) Slow moving vehicle to drive off roadway.--(1) Except when reduced speed is necessary for safe operation or in compliance with law, whenever any person drives a vehicle upon a roadway having width for not more than one lane of traffic in each direction at less than the maximum posted speed and at such a slow speed as to impede the normal and reasonable movement of traffic, the driver shall, at the first opportunity when and where it is reasonable and safe to do so and after giving appropriate signal, drive completely off the roadway and onto the berm or shoulder of the highway. The driver may return to the roadway after giving appropriate signal only when the movement can be made in safety and so as not to impede the normal and reasonable movement of traffic.(2) A pedalcycle may be operated at a safe and reasonable speed appropriate for the pedalcycle. A pedalcycle operator shall use reasonable efforts so as not to impede the normal and reasonable movement of traffic.(c) Establishment of minimum speed limits.--At any other time when the department or local authorities under their respective jurisdictions determine on the basis of an engineering and traffic investigation that slow speeds on any highway or part of a highway impede the normal and reasonable movement of traffic, the 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. The minimum limit shall be effective when posted upon appropriate fixed or variable signs.Amended by P.L. 27 2012 No. 3, § 4, eff. 4/2/2012. 1976, June 17, P.L. 162, No. 81, § 1, effective July 1, 1977.
