22400
. (a) No person shall drive upon a highway at such a slow
speed as to impede or block the normal and reasonable movement of
traffic unless the reduced speed is necessary for safe operation,
because of a grade, or in compliance with law.
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.
