According to the way I read the law 4 wheelers are allowed on the road...Here is a link http://www.kytc.state.ky.us/drvsmrt/atvlaws.htm It says this: A person may operate an all-terrain vehicle on any two (2) lane public highway in order to cross the highway. In crossing the highway under this paragraph, the operator must cross the highway at as close to a ninety (90) degree angle as is practical and safe, and cannot travel on the highway for more than two-tenths (2/10) of a mile. (1) The Transportation Cabinet may designate, and a city or county government may designate, those public highways, segments of public highways, and adjoining rights-of-way of public highways under its jurisdiction where all-terrain vehicles that are prohibited may be operated. (2) A person operating an all-terrain vehicle on a public highway under this subsection must possess a valid operator's license. (3) A person operating an all-terrain vehicle on a public highway under this subsection must comply with all applicable traffic regulations. (4) A person cannot operate an all-terrain vehicle under this subsection unless the all-terrain vehicle has at least one headlight and two taillights, which must be illuminated at all times the vehicle is in operation. (5) A person operating an all-terrain vehicle under this subsection must restrict the operation to daylight hours, except when engaged in snow removal.
