The State traffic laws regulating the speed of vehicles shall
be applicable upon all streets within the City, except that the City
may by ordinance declare and determine upon the basis of engineering
and traffic investigation that certain speed regulations shall be
applicable upon specified streets or in certain areas, in which event
it shall be unlawful for any person to drive a vehicle at a speed
in excess of any speed so declared when signs are in place giving
notice thereof.
The City Traffic Engineer is authorized to regulate the timing
of traffic signals so as to permit the movement of traffic in an orderly
and safe manner at speeds slightly at variance from the speeds otherwise
applicable within the district or at intersections and shall erect
appropriate signs giving notice thereof.
No person shall drive a motor vehicle at such a slow speed as
to impede or block the normal and reasonable movement of traffic,
except when reduced speed is necessary for safe operation or in compliance
with law. Peace Officers may enforce the provisions of this Section
by directions to drivers, and in the event of apparent willful disobedience
to this provision and refusal to comply with direction of an officer
in accordance herewith, the continued slow operation by a driver is
an ordinance violation.
No person shall operate a motor vehicle upon those portions
of the roadways which are set forth and described in Schedule I at
a rate of speed in excess of that speed limit set for such portions
of the roadways by said Schedule.
[R.O. 1993 § 320.050; Ord. No.
1864 § 8, 2-7-1956;
CC 1969 § 16-48]
The use of, and results determined by, any radar, speed meter,
machine or mechanism which seeks to reduce the error of manual operation
to a minimum in determining the speed of a moving vehicle shall be
acceptable as evidence where driving in excess of posted speed limits
is the cause of action or prosecution; but the use thereof shall not
be construed to exclude any competent evidence secured by any other
manner or means.
