(Pub. L. 103–272, § 1(e), July 5, 1994, 108 Stat. 1020; Pub. L. 112–141, div. C, title II, § 32931(c), July 6, 2012, 126 Stat. 829.)

In subsection (a), the words “a vehicle consisting” are substituted for “any combination” for clarity. The words “Dwight D. Eisenhower System of Interstate and Defense Highways” are substituted for “National System of Interstate and Defense Highways” because of the Act of October 15, 1990 (Public Law 101–427, 104 Stat. 927).

In subsection (b), the words “Not later than 60 days after the date of the enactment of this Act, the Secretary shall initiate a rulemaking proceeding” are omitted as executed.

Amendments 2012—Subsec. (b). Pub. L. 112–141, which directed substitution of “The Secretary shall maintain” for “Not later than December 18, 1994, the Secretary shall prescribe”, was executed by making the substitution for “Not later than December 18, 1994, the Secretary of Transportation shall prescribe”, to reflect the probable intent of Congress.
