No person shall operate or drive a motor vehicle (except emergency
vehicles on emergency runs) or any other conveyance on any street,
boulevard, thoroughfare, or public way, in this City, at any time,
at a rate of speed in excess of twenty-five (25) miles per hour except
as posted.
No person shall operate or drive a motor vehicle or other conveyance
upon any designated roadway within three hundred (300) feet of any
public or private school at a rate of speed in excess of fifteen (15)
miles per hour during the period as posted; except that the City Council
may adopt higher speed limits in a particular school zone upon a finding
that such higher speed limits are appropriate in that particular instance;
and the City Council may change the number of feet before any public
or private school within which no person shall operate or drive a
motor vehicle or other conveyance upon a finding that such would be
appropriate in a particular instance.
Whenever a zone in which the maximum speed at which a vehicle may
be driven shall have been prescribed by ordinance, the City Traffic
Engineer shall cause appropriate signs to be placed in conspicuous
positions on the street.
Nothing in this Section shall be so construed as to prevent the enforcement
of speed limitations prescribed for specified, general districts of
the City, whether or not maximum speed signs are placed or maintained
in such districts.
