No person shall bring a vehicle to a complete stop upon a highway so as to impede or block the normal and reasonable movement of traffic unless the stop is necessary for safe operation or in compliance with law.
(b) Whenever the Department of Transportation determines on the basis of an engineering and traffic survey that slow speeds on any part of a state highway consistently impede the normal and reasonable movement of traffic, the department 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, when appropriate signs giving notice thereof are erected along the part of the highway for which a minimum speed limit is established.
Subdivision (b) of this section shall apply only to vehicles subject to registration.
In Chavez v. City of Oakland C.A., 9 (Cal.) 2011, 414 Fed.Appx. 939, 2011 WL 566760, unreported, the Court found the officer had probable cause to arrest a newspaper reporter, who exited his or her vehicle on the freeway to take photographs of an accident, for impeding the normal and reasonable movement of traffic. A fire truck was required to merge around the reporter's parked car to reach the accident scene and the reporter willfully refused to comply with two directives from the officer to return to his car and leave the scene of the accident.
