SDCL § 32-20-4.1: Eye protective device or windscreen required--Violation as petty offense.

No person may operate a motorcycle unless he is wearing an eye protective device or unless the motorcycle is equipped with a windscreen of sufficient height and design so as to provide adequate eye protection to the operator when seated on the motorcycle in the normal operating position. However, no person may operate a motorcycle during the time period when headlights must be lighted while wearing an eye protective device that is tinted or shaded to reduce the light transmittance of the device to a level below thirty-five percent. A violation of this section is a petty offense.
