It looks like we are required to use "safety glass" and windshield wipers. This makes things harder for us Ohioans. Any suggestions?
4513.26 Safety glass required for new vehicles.
(A) No person shall sell any new motor vehicle nor shall any new motor vehicle be registered, and no person shall operate any motor vehicle, which is registered in this state and which has been manufactured or assembled on or after January 1, 1936, unless the motor vehicle is equipped with safety glass wherever glass is used in the windshields, doors, partitions, rear windows, and windows on each side immediately adjacent to the rear window.
"Safety glass" means any product composed of glass so manufactured, fabricated, or treated as substantially to prevent shattering and flying of the glass when it is struck or broken, or such other or similar product as may be approved by the registrar of motor vehicles.
Glass other than safety glass shall not be offered for sale, or sold for use in, or installed in any door, window, partition, or windshield that is required by this section to be equipped with safety glass.
4513.24 Windshield and windshield wipers.
(A) No person shall drive any motor vehicle on a street or highway in this state, other than a motorcycle or motorized bicycle, that is not equipped with a windshield.

No sign, poster, or decal shall be displayed in the front windshield in such a manner as to conceal the vehicle identification number for the motor vehicle when, in accordance with federal law, that number is located inside the vehicle passenger compartment and so placed as to be readable through the vehicle glazing without moving any part of the vehicle.
(2) Division (B)(1) of this section does not apply to a person who is driving a passenger car with an electronic device, including an antenna, electronic tolling or other transponder, camera, directional navigation device, or other similar electronic device located in the front windshield if the device meets both of the following:
(a) It does not restrict the vehicle operator's sight lines to the road and highway signs and signals.
(b) It does not conceal the vehicle identification number.
(3) Division (B)(1) of this section does not apply to a person who is driving a commercial car with an electronic device, including an antenna, electronic tolling or other transponder, camera, directional navigation device, or other similar electronic device located in the front windshield if the device meets both of the following:
(a) It does not restrict the vehicle operator's sight lines to the road and highway signs and signals.
(b) It is mounted not more than six inches below the upper edge of the windshield and is outside the area swept by the vehicle's windshield wipers.
(C) The windshield on every motor vehicle, streetcar, and trackless trolley shall be equipped with a device for cleaning rain, snow, or other moisture from the windshield. The device shall be maintained in good working order and so constructed as to be controlled or operated by the operator of the vehicle, streetcar, or trackless trolley.
