12BA Concessional mass limit

(1) For the purposes of paragraphs 12B (2) (a) and 13 (1) (aa) of the Act, the concessional mass limit of a vehicle is, subject to subregulation (2), calculated as the sum of:

(a) the maximum permitted laden mass specified in column 3 of an item in Schedule 3 (the vehicle’s permitted laden mass) for the vehicle’s axle spacing; and

(b) whichever of the following applies:

(i) if the vehicle’s permitted laden mass is 55 tonnes or less — 5% of the vehicle’s permitted laden mass or 1 tonne, whichever is less;

(ii) if the vehicle’s permitted laden mass is over 55 tonnes — 2 tonnes.

Note Column 4 of Schedule 4 sets out the resulting amounts of a calculation under paragraph (b) by reference to axle groups.

(2) If the concessional mass limit calculated under subregulation (1) exceeds the manufacturer’s rating for the vehicle, the concessional mass limit is taken to be the manufacturer’s rating.

Note The concessional mass limit worked out under this regulation is a separate amount to the maximum permitted gross mass amount worked out under regulation 12A.
