(A) No snowmobile may be driven upon any roadway within the corporate limits of the city at a speed which is greater than is reasonable and proper with regard to traffic conditions and the use of the highway, or endangers the safety of any person or property. The fact that the speed of the snowmobile does not exceed the applicable maximum speed limit does not relieve the driver of the snowmobile from the duty to decrease speed when approaching and crossing an intersection, when and going around the curve, when approaching a hillcrest, when traveling upon any narrow or winding road-way, or when special hazards exist with respect to pedestrians or other traffic or by reason of weather or highway conditions. Speed must be decreased as may be necessary to avoid colliding with any person or vehicle on or entering the highway in compliance with legal requirements and a duty of all persons to use due care.
(B) Unless some other speed restriction is established by the posting of speed limit signs under the authority of the City Council, the maximum speed limits for snowmobiles within the corporate limits of the city is as follows:
(1) Thirty miles per hour in any residential or business district.
(2) Fifteen miles per hour in any alley.
(3) Twenty miles per hour while passing through any school zone, properly posted.
