No person shall stop, stand or park a vehicle in any place posted
as restricted to physically handicapped persons unless he is a holder
of a valid, special parking permit for the physically handicapped
issued by the County of Nassau or is the operator of a specially registered
vehicle for the physically handicapped issued by the New York State
Department of Motor Vehicles, and, in both cases, such vehicle is
being actually used at that time for the transportation of a physically
handicapped person.
