(b) The Executive Director of the Department of Transportation is required by law to promulgate rules for the issuance of such permits and no person, firm or corporation shall operate or authorize the operation of any such vehicle unless a valid Annual Operating Permit has been issued to the owner of such vehicle by the Permits Section of the Department of Transportation, properly signed by the Executive Director of the Department of Transportation or his authorized designee, and the original or certified copy thereof is available for inspection at all times in the vehicle cab. No other trailer configuration or multiple trailer combination shall be authorized or operated under said permit. Any violation of a permit provision shall constitute grounds for immediate permit suspension or revocation of said permit.

(1) vehicles bearing an out-of-state license are ineligible for a permit of any type for a movement between an origin and destination, both of which are located within Oklahoma (intrastate movement), unless said vehicle is covered under an agreement between the licensing state and the State of Oklahoma which prorates the licensing and/or registration fees for such vehicles, or unless such vehicle has been temporarily licensed for operation in this state; and

(2) no such vehicle combination shall operate under conditions of decreased visibility or when lateral winds in excess of 45 miles per hour are present or during periods when pavement surfaces are slick, icing, icy or snow packed; and

(3) such vehicle combinations shall operate only upon the Dwight D.

(4) reasonable access to and from terminals and for fuel, food, repairs and rest shall not exceed 5 statute miles from the vehicle's point of access to, or exit from, those highways authorized for use in paragraph (3) of this subsection and as set forth in 730:50-5-6(h); and

(e) The driver must at all times during operation of said vehicle be under the control and supervision of the holder of the special Annual Operating Permit.

Any suspension of said permit shall remain in effect for a period of not less than 6 months. Any revocation of said permit shall be for a period of not less than 1 year.
