Eisenhower System of Interstate and Defense Highways and those classes of qualifying Federal-aid Primary System highways designated by the Secretary of Transportation under section 31111 (e) of this title, of any commercial motor vehicle combination (except a vehicle or load that cannot be dismantled easily or divided easily and that has been issued a special permit under applicable State law) with more than one property-carrying unit (not including the truck tractor) whose property-carrying units are more than—

(5) Nebraska may allow the operation of a truck tractor and 2 trailers or semitrailers not in actual lawful operation on a regular or periodic basis on June 1, 1991, if the length of the property-carrying units does not exceed 81 feet 6 inches and such combination is used only to transport equipment utilized by custom harvesters under contract to agricultural producers to harvest one or more of wheat, soybeans, and milo during the harvest months for such crops, as defined by the State of Nebraska.
(d) Additional Limitations.—
(1) A commercial motor vehicle combination whose operation in a State is not prohibited under subsections (b) and (c) of this section may continue to operate in the State on highways described in subsection (b) only if at least in compliance with all State laws, regulations, limitations, and conditions, including routing-specific and configuration-specific designations and all other restrictions in force in the State on June 1, 1991.

(3) A State making a minor adjustment of a temporary and emergency nature as authorized by paragraph (1) of this subsection or further restricting or prohibiting the operation of a commercial motor vehicle combination as authorized by paragraph (2) of this subsection shall advise the Secretary not later than 30 days after the action. The Secretary shall publish a notice of the action in the Federal Register.

(1) Not later than February 16, 1992, each State shall submit to the Secretary for publication a complete list of State length limitations applicable to commercial motor vehicle combinations operating in the State on the highways described in subsection (b) of this section. The list shall indicate the applicable State laws and regulations associated with the length limitations. If a State does not submit the information as required, the Secretary shall complete and file the information for the State.
(2) Not later than March 17, 1992, the Secretary shall publish an interim list in the Federal Register consisting of all information submitted under paragraph (1) of this subsection. The Secretary shall review for accuracy all information submitted by a State under paragraph (1) and shall solicit and consider public comment on the accuracy of the information.
(3) A law or regulation may not be included on the list submitted by a State or published by the Secretary merely because it authorized, or could have authorized, by permit or otherwise, the operation of commercial motor vehicle combinations not in actual operation on a regular or periodic basis before June 2, 1991.
(4) Except as revised under this paragraph or paragraph (5) of this subsection, the list shall be published as final in the Federal Register not later than June 15, 1992.

After publication of the final list, commercial motor vehicle combinations prohibited under subsection (b) of this section may not operate on the Dwight D. Eisenhower System of Interstate and Defense Highways and other Federal-aid Primary System highways designated by the Secretary except as published on the list. The list may be combined by the Secretary with the list required under section 127 (d) of title 23.
(5) On the Secretary’s own motion or on request by any person (including a State), the Secretary shall review the list published under paragraph (4) of this subsection.

If the Secretary decides there was a mistake, the Secretary shall publish the correction.

(1) to allow the operation on any segment of the Dwight D. Eisenhower System of Interstate and Defense Highways of a longer combination vehicle prohibited under section 127 (d) of title 23;
(2) to affect in any way the operation of a commercial motor vehicle having only one property-carrying unit; or
(3) to affect in any way the operation in a State of a commercial motor vehicle with more than one property-carrying unit if the vehicle was in actual operation on a regular or periodic basis (including seasonal operation) in that State before June 2, 1991, that was authorized under State law or regulation or lawful State permit.
