Land Transport Rule - Draft Land Transport Rule: Vehicle Dimensions and Mass 2016 41001| NZ Transport Agency
Vehicle Dimensions and Mass 2016
Rule 41001
Land Transport Rule: Vehicle Dimensions and Mass 2016 specifies requirements for dimension and mass limits for vehicles operating on New Zealand roads. It also includes some provisions that relate to the performance and operation of motor vehicles.
This Rule revokes and replaces Land Transport Rule: Vehicle Dimensions and Mass 2002 (the 2002 Rule).
The Rule is designed to create a reasonable balance between the efficient operation of the heavy motor vehicle fleet, within the constraints imposed by the road network, while ensuring that heavy motor vehicles are operated safely. It does this by creating limits to the permitted dimensions and mass of vehicles, with particular emphasis on large combination vehicles.
This Rule clarifies and rationalises the existing requirements for vehicle dimension and mass limits. It also includes some limited increases in axle and gross mass limits over those stated in the 2002 Rule.
This Rule continues the distinction between general access limits and the requirement to obtain a permit if the vehicle is to be operated at higher mass or is a large overdimension vehicle or load. This Rule applies to all motor vehicles only in respect of projecting loads to cycles.
This Rule cannot legislate for every situation and every driver and operator has a responsibility to exercise good judgement. This is consistent with the general duties stated in section 6, 7, 8 and 9 of the Land Transport Act 1998 (which relate to vehicle safety, driver responsibility, and the need to secure loads). The issue of a permit under this Rule does not displace those general responsibilities. This Rule also does not displace a restriction imposed by other legislation. For example, general access limits do not allow a heavy vehicle to cross a bridge with a posted limit (authorised by a bylaw) that is lower than the vehicle’s actual gross mass.

(a) a physical test of the vehicle on a tilt table according to the procedure in the SAE J2180-DEC 1998 of The American Society of Automotive Engineers and carried out using a procedure approved by International Accreditation New Zealand; or
(b) a calculation using any “SRT Calculator” approved by the Agency and published on the Agency’s website; or
(c) a calculation using the method in Schedule 6.1; or
(d) any other methodology approved by the Agency and published on its website.
Determining the appropriate loading of a vehicle for different load types
2.5(4) The following methodology must be applied to determine the appropriate vehicle loading:
(a) for mixed freight loads and uniform density loads:
(i) if the vehicle is loaded to the maximum internal body height or to the maximum height specified in Table 1, the maximum allowable gross mass must be determined;
(ii) if the vehicle is loaded to the maximum allowable gross mass specified in section 3, the maximum allowable load height must be determined;
(b) for all other loads, for a particular height above ground level of the centre of gravity of the load, the maximum allowable gross mass of the vehicle and its load must be determined.
2.5(5) The combination of load height and load mass in 2.5(4) applies for a particular standard type of loading that must be appropriate for the particular type of deck or body with which a heavy motor vehicle is fitted, and must be one of the following types of load:
(a) mixed freight, where 70% of the load mass is in the bottom half of the load space and 30% of the load mass is in the top half of the load space;
(b) uniform density, where the load is uniformly distributed between the load bed and the top of the load so that the centre of gravity of the load lies midway between the load bed and the load height;
(c) other loads where the height above ground of the centre of gravity of the load is entered in the calculation. 2.5(6) If the deck or body fitted on a heavy motor vehicle is changed to allow a different type of load to be carried, the SRT must be determined, and the vehicle recertified, for the new loading.
2.5(7) A motor vehicle with a retractable axle or axles must be assessed under a methodology in 2.5(3) with its axles in a non-retracted position.
2.5(8) The maximum allowable load height for logs must be determined by—
(a) measuring the height above ground of the highest point of the load; and
(b) if the height in paragraph (a) does not comply with the minimum SRT, then measuring the height above ground of the highest point at each end of the highest packet and calculating an average of the two measurements; and
(c) if the height in paragraph (a) or (b) does not comply with the minimum SRT, and the load comprises multiple packets and the highest points of all of the packets differ in height by no more than 1 m, measuring the average height of each packet by the method described in paragraph (b) and calculating an average height of all packets.
2.5(9) SRT test results must be—
(a) verified for compliance with loading and mass specifications by a vehicle inspector, or an inspecting organisation; and
(b) specified in a document of compliance that complies with a form approved by the Agency.
2.5(10) SRT test results must be displayed on a vehicle’s certificate of loading—
(a) in this format: “SRT 0.35 g X1/Y1, Y2/X2”; and
(b) with the options for load height and gross mass specified as—
(i) maximum allowable load height above ground in metres to two decimal places (X1);
(ii) maximum safe gross mass to nearest tonne to meet SRT of 0.35 g (Y1);
(iii) maximum allowable gross mass to nearest tonne (Y2);
(iv) maximum safe load height above ground in metres to two decimal places to meet SRT of 0.35 g (X2).
Note: X1/Y1 represents the maximum allowable load height (X1) of the vehicle that is used to calculate the maximum safe gross mass (Y1) of the vehicle to meet an SRT of 0.35 g. Y2/X2 represents the maximum allowable gross mass (Y2) of the vehicle when loaded that is used to calculate the maximum safe load height (X2) of the vehicle to meet an SRT of 0.35 g. The procedure is fully explained in 2.5(4).
Calculating allowable gross mass

(e) an axle mass limitation placed by a road controlling authority under any enactment on any route or structure. Note: Requirements for vehicle mass are divided into general access (where the vehicle can operate without a permit, subject to any specific route or bridge restrictions) and heavier mass allowances which are only available where a permit to exceed general access limits has been issued to the vehicle operator.
Section 3 and Tables 2 (axle mass) and 3A or 3B (gross mass) describe limits for vehicles operating under general access. Section 4 and Tables 4 (axles) and 5 (gross mass) describe limits for vehicles operating under a permit.
Gross mass limits are designed to manage the impact of heavy vehicles on bridges and other road infrastructure.
Axle limits are designed to manage the impact of heavy vehicles on pavements.
This section deals with axles fitted with standard tyres. Axles fitted with specialist wide profiletyres must also meet these limits but may apply for a permit to exceed the Table 2 limits on the basis of their vehicle axle index.
