(A)   No person shall drive a vehicle on any street in the city at a speed greater than is reasonable and prudent under the conditions and having regard to the actual and potential hazards then existing. Consistent with the foregoing, every vehicle shall be driven at a safe and appropriate speed when approaching and crossing an intersection or railway grade crossing, when approaching and going around a curve, when approaching a hill crest, when traveling upon any narrow street or winding roadway and when special hazards exist with respect to pedestrians or other traffic or by reason of weather or street or roadway conditions.
   (B)   Except when a special hazard exists that requires lower speed for compliance with division (A) above, the limits specified in this section or established as hereinafter authorized shall be maximum lawful speeds and no person shall drive a vehicle on any street or highway of the city at a speed in excess of such maximum limits.
   (C)   All vehicles operated within the city shall not exceed 25 mph on any streets, alleys and public ways, except on those streets or highways on which the state’s Highway Department or the city’s Traffic Department declares and determines upon the basis of engineering and traffic investigation that the speed of 25 mph on certain streets and highways is less than or is more than is necessary for the safe operation of vehicles thereon; in which event, it shall be unlawful for any person to drive a vehicle at a speed in excess of the posted speed when signs are erected giving notice thereof.
   (D)   All vehicles operated within the city shall not exceed 15 mph when passing a school building, or the grounds thereof, during recess and while children are going to or leaving school, during the opening or closing hours and when appropriate signs giving notice of the existence of the school are erected; except that, on controlled-access highways, expressways and freeways if the right-of-way line fence has been erected without pedestrian opening, the school speed limit shall not apply.
