SCHEDULE 1 – General mass limits

section 6(2)

Part 1 - Imposition of general mass limits

1 General mass limits

(1) The mass limits stated in this Schedule apply to a heavy vehicle or a component of a heavy vehicle.

(2) If, in relation to a particular vehicle or component, this Schedule provides for 2 or more mass limits imposing different mass limits that apply in the same circumstances, the lower or lowest mass limit applies and the other mass limit or mass limits must be disregarded.

2 Mass limits for a single vehicle or combination

(1) The mass of a single vehicle or combination must not be more than the lower of the following masses--

(a) the mass that is the lower or lowest of the following--

(i) for a complying bus without a trailer--

(A) if the bus has only 2 axles but is not an eligible 2-axle bus--16t; or

(B) if the bus has a rear tandem axle group fitted with single tyres on 1 axle and dual tyres on the other axle but is not an eligible 3-axle bus--20t; or

(C) if the bus has a rear tandem axle group fitted with dual tyres on all axles--22.5t;

(ii) for a complying bus with a trailer, the sum of--

(A) the mass limits for the bus mentioned in subparagraph (i); and

(B) the mass that is the sum of the mass limits applying to the trailer's axle groups and single axles under Table 1 of Part 2;

(iii) for a bus that is an ultra-low floor bus with no axle groups and only 2 single axles but is not an eligible 2-axle bus--16t;

(iiia) for an eligible 2-axle bus--18t;

(iiib) for an eligible 3-axle bus--22t;

(iv) for a complying steer axle vehicle that is neither a B-double nor a road train--43t;

(v) for a prime mover with a twinsteer axle group towing a tri-axle semitrailer--46.5t;

(vi) for a vehicle that is not mentioned in subparagraphs (i) to (v) and that is neither a B-double nor a road train--42.5t;

(b) the mass that is the sum of the mass limits stated in Table 1 of Part 2 in relation to each of the axle groups and single axles of the single vehicle or combination.

(2) A vehicle is not within the amount of the mass stated in subsection (1)(b) if any single axle or axle group fitted to the vehicle has a mass in excess of the mass limits applying to the single axle or axle group.

(3) The purpose of subsection (2) is to ensure that a vehicle cannot be brought within the mass stated in subsection (1)(b) by off-setting an under limit mass on an axle group or single axle against an over limit mass on another axle group or single axle.

(4) In a combination, the mass of a dog trailer or pig trailer must not be more than the mass of the towing vehicle.

(4A) In a combination, the mass on the axle group or single axle of a tag trailer must not be more than the sum of the mass on all of the axles of the towing vehicle.

(5) In this section--

"over limit mass" means the amount by which the mass on an axle group or single axle of a vehicle is more than the mass stated in relation to the axle group or single axle in Table 1 of Part 2.

"single vehicle" means a heavy motor vehicle that is not towing another vehicle.

"under limit mass" means the amount by which the mass on an axle group or single axle of a vehicle is less than the mass stated for the axle group or single axle in Table 1 of Part 2.

3 Mass limits for a vehicle with a particular axle space less than 2.5m

If the distance between any 2 axles on a heavy vehicle that are not part of the same axle group is less than 2.5m, the mass of the heavy vehicle must not be more than 15t.

4 Mass limits for a single axle or axle group

The mass on a single axle or axle group must not be more than the mass limit stated in relation to the single axle or axle group in Table 1 of Part 2.

5 Mass limits relating to axle spacing generally

(1) The mass of a heavy vehicle, other than a road train or a B-double, relating to an axle spacing of the vehicle must not be more than--

(a) the mass limit stated in Table 2 of Part 2 in relation to the axle spacing; or

(b) if--

(i) the heavy vehicle is a complying steer axle vehicle; and

(ii) the steer axle is used to calculate the axle spacing mentioned in paragraph (a)--

the mass limit mentioned in paragraph (a) increased by 0.5t.

(2) The mass of a B-double relating to an axle spacing of the B-double must not be more than--

(a) the mass limit stated in Table 3 of Part 2 in relation to the axle spacing; or

(b) if--

(i) the B-double is a complying steer axle vehicle; and

(ii) the steer axle is used to calculate the axle spacing mentioned in paragraph (a)--

the mass limit mentioned in paragraph (a) increased by 0.5t.

(3) The mass of a road train relating to an axle spacing of the road train must not be more than the mass limit stated in Table 4 of Part 2 in relation to the axle spacing.

(4) Each of the following is an axle spacing of a heavy vehicle--

(a) the distance from the centre-line of a single axle to the centre-line of another single axle;

(b) the distance from the centre-line of a single axle to the centre-line of the furthest axle in any axle group;

(c) the greatest distance between the centre-lines of axles in any 2 axle groups.

Examples--:

(5) The mass limits imposed by subsections (1) to (3) apply to the sum of the mass on each axle group or single axle within the heavy vehicle's axle spacing.

(6) The axle groups or single axles that are within an axle spacing of a heavy vehicle are the end axles and every axle group or single axle between the end axles.

Example--: In the examples under subsection (4), for the longest axle space, the mass limits imposed by subsections (1) to (3) apply to the sum of the mass on each of the axle groups or single axles made up of the 6 axles shown as included within the spacing.

(7) In this section--

"end axles" , in relation to an axle spacing, are the axle groups or single axles on each end of the axle spacing.
