It shall be unlawful for any person to operate a motor vehicle at such a slow speed as to impede or block the normal and reasonable movement of traffic at the point of operation thereof, except when a reduced speed is necessary for safe operation or in compliance with any law, rule or regulation. (1952 Code § 10-05-05)

6-6-4: Speeding Within School Zone


No person shall operate a vehicle on a highway in a marked school zone in excess of the speed limit as established in subsection 6-6-2C of this chapter.

An infraction is a civil public offense, not constituting a crime, which is punishable only by a penalty and for which no period of incarceration may be imposed. There is no right to a trial by jury of a citation or complaint for an infraction and such trials shall be held before the court without a jury. (1952 Code § 10-05-06)
