Notwithstanding any other provision of law to the contrary, the director may waive, in whole or in part, after notice and an opportunity for comment, application of any provision of this act or any regulation promulgated pursuant to this act with respect to a class of persons or class of commercial motor vehicles if the director determines that such waiver is not contrary to the public interest and does not diminish the safe operation of commercial motor vehicles. A waiver under this section shall be published in the New Jersey Register, together with reasons for the waiver. A waiver shall not be granted if the granting of the waiver is likely to or will place the State in the position of not being in substantial compliance with the requirements set forth in the "Commercial Motor Vehicle Safety Act of 1986," Pub. L. 99-570 (49 U.S.C. s. 2701 et seq.). The director may make such applications as he deems appropriate to the Secretary of the United States Department of Transportation to obtain any waiver permitted under federal law.
