(a) No person may operate or be a passenger on any motorcycle or motor-driven cycle unless the person is wearing securely fastened on his or her head by either a neck or chin strap a protective helmet designed to deflect blows, resist penetration and spread impact forces. Any helmet worn by an operator or passenger shall meet the current performance specifications established by the American National Standards Institute Standard, Z 90.1, the United States Department of Transportation Federal Motor Vehicle Safety Standard No. 218 or Snell Safety Standards for Protective Headgear for Vehicle Users.

(b) No person may operate or be a passenger on any motorcycle or motor-driven cycle unless the person is wearing safety, shatter-resistant eyeglasses, excluding contact lenses, or eye goggles or face shield that complies with the performance specifications established by the American National Standards Institute for Head, Eye and Respiratory Protection, Z 2.1. In addition, if any motorcycle, motor-driven cycle or moped is equipped with a windshield or windscreen, the windshield or windscreen shall be constructed of safety, shatter-resistant material that complies with the performance specifications established by Department of Transportation Federal Motor Vehicle Safety Standard No. 205 and American National Standards Institute, Safety Glazing Materials for Glazing Motor Vehicles Operated on Land Highways, Standard Z 26.1.

(d) A person operating a motorcycle, motor-driven cycle or moped shall ride in a seated position facing forward and only upon a permanent operator’s seat attached to the vehicle. No operator may carry any other person nor may any other person ride on the vehicle unless the vehicle is designed to carry more than one person, in which event a passenger may ride behind the operator upon the permanent operator’s seat if it is designed for two persons, or upon another seat firmly attached to the vehicle to the rear of the operator’s seat and equipped with footrests designed and located for use by the passenger or in a sidecar firmly attached to the vehicle. No person may ride side saddle on a seat. An operator may carry as many passengers as there are seats and footrests to accommodate those passengers. Additional passengers may be carried in a factory-produced sidecar provided that there is one passenger per seat. Passengers riding in a sidecar shall be restrained by safety belts.

(e) Every motorcycle, motor-driven cycle and moped shall be equipped with a rearview mirror affixed to the handlebars or fairings and adjusted so that the operator has a clear view of the road and condition of traffic behind him or her for a distance of at least two hundred feet.
