It shall be unlawful to operate any trailer, not otherwise required to be licensed by law, which is used for the hauling of cattle, horses, sheep or hogs upon the roads or highways of the State of Oklahoma unless that trailer bears an identifying number. Trailers owned by individual persons shall be identified with the driver's license number of the owner; provided that, trailers owned by corporations, partnerships and other associations or owned by a person who has no driver's license shall be identified with numbers as designated by regulation by the State Board of Agriculture with the advice of the Oklahoma Department of Public Safety. The identifying number shall be in Arabic numerals in a contrasting color of not less than two (2) inches high painted or otherwise affixed to the rear of the trailer so as to be clearly visible from the rear at all times and in such a manner as to reasonably assure against its alteration or destruction. The State Board of Agriculture may issue regulations, not inconsistent with this act and with the advice of the Oklahoma Department of Public Safety, further directing the affixing of identifying numbers to livestock trailers. It shall be unlawful to alter a livestock trailer identifying number other than to comply with this act or regulations issued pursuant thereto. No fee shall be charged for the issuance of any trailer identification number required by this act.
