§ 71.01  SPEED LIMITS.
   (A)   It has been determined on the basis of an engineering and traffic investigation that the statutory maximum speed limits of 30 miles per hour in an urban district and 55 miles per hour on the interstate defense network of dual highways and in other locations, as permitted by state law, are either greater or less than is reasonable and safe under the conditions found to exist on the streets or parts of streets described in the schedule of maximum speed limits in Ch. 73, Sched. I, of this code and that it is necessary to alter the statutory maximum speed limits on those streets or parts of streets.
   (B)   The maximum speed limits established in the schedule of maximum speed limits in Ch. 73, Sched. I, are determined and declared to be reasonable and safe maximum limits for the streets and parts of streets listed in the schedule.
   (C)   The maximum speed limits established in the schedule of maximum speed limits in Ch. 73, Sched. I, shall be effective at all times, unless otherwise indicated, when appropriate signs giving notice of the maximum speed limits are erected on the streets and parts of streets listed in the schedule.
   (D)   Except when state law requires a lower speed, the maximum speed limits specified in the schedule of maximum speed limits in Ch. 73, Sched. I, shall be maximum lawful speeds, and no person shall drive a vehicle on the designated streets and parts of streets in excess of the maximum speed limits.
   (E)   A person who violates this section commits a class C ordinance violation, and a judgment may be entered against the violator.
