[R.O. 2007 §320.050; Ord. No. 4030 §§2—4, 3-27-2000]
Speed limits are set according to standards established by the City Traffic Engineer, and these standards include consideration for pedestrian use, traffic volume and congestion, traffic flow patterns and other criteria necessary to make the roadways as safe as possible. These speed limits may be lower in certain areas to provide for the safe passage of vehicles, safer ingress and egress to the roadway, and to assure safer areas for pedestrians and bicycles to travel on or near the roadway.
For the purposes of this Section, a special enforcement area shall be defined as follows:
Any public or private street or roadway where the speed limit has been established at twenty-five (25) miles per hour or less, and/or any street or roadway posted as a school speed zone.
Conviction of a violation of this Section is punishable by a fine of up to five hundred dollars ($500.00) or imprisonment in the St. Charles County Jail for a period up to three (3) months, or to both such fine and imprisonment. In order to determine the fine, any person found guilty of a moving motor vehicle violation in a special enforcement area in the City of O'Fallon shall be fined at a rate double the standard fine for such moving motor vehicle violation.
