Objective of the Rule

Land Transport Rule: Vehicle Dimensions and Mass 2016 (the Rule) 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). It applies to all motor vehicles and cycles.

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, and ensuring that heavy motor vehicles are operated safely. It does this by creating limits to the permitted configurations, dimensions and mass of vehicles, with particular emphasis on large combination vehicles.

The 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 from the limits in the 2002 Rule.

The Rule continues the distinction between dimension and mass limits for general access and the allowance to operate a vehicle with higher mass or with larger dimensions if a permit is obtained.

The Rule does not prescribe every situation; every driver and operator has a responsibility to exercise good judgement. This is consistent with the general responsibilities stated in sections 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. The 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 (fixed by a road controlling authority) that is lower than the vehicle’s actual gross mass.

Extent of consultation

Consultation on the Rule began with the release of a discussion document on 9 December 2015 outlining proposals for change to the 2002 Rule. Following this consultation, which closed on 17 February 2016, a proposed draft of the Rule (yellow draft) was prepared and released along with explanatory material on 8 July 2016. The NZ Transport Agency sent notice of the yellow draft by letter or email to approximately 1560 groups and individuals who had registered an interest in the Vehicle Dimensions and Mass Rule.

One further proposal to amend the maximum width of two wheeled vehicles was consulted on separately as part of Land Transport Rule: Omnibus Amendment 2016. The NZ Transport Agency released a draft Omnibus Amendment Rule (yellow draft) for this proposal, along with 34 other proposals for minor or technical amendments to various Land Transport Rules, on 15 July 2016. Notice of the Rule proposals were sent by letter or email to approximately 3170 groups and individuals who had registered an interest in the Rules to be amended.

The yellow drafts of both Rules were made available through the NZ Transport Agency’s Contact Centre and, together with Questions and Answers, were also available on the NZ Transport Agency’s website. The availability of the yellow drafts for comment was publicised in the daily newspapers in Auckland, Hamilton, Wellington, Christchurch and Dunedin and in the New Zealand Gazette.

The NZ Transport Agency received 65 submissions on the yellow draft of the Rule and 35 submissions on the yellow draft of the Omnibus Amendment Rule, of which 17 commented on the proposal to amend the maximum width of two wheeled vehicles. The submissions received were taken into account in finalising the draft Rule. The proposed Rule was then submitted to the Associate Minister of Transport for signing.

3.17 Determining the appropriate loading of a vehicle for different load types

3.17(1) 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 Schedule 2, the maximum allowable gross mass must be determined:
  • (ii) if the vehicle is loaded to the maximum allowable gross mass specified in section 4, 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.

3.17(2) The combination of load height and load mass in 3.17(1) 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 used to determine SRT.

3.17(3) 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.

3.17(4) A motor vehicle with a retractable axle or axles must be assessed using a method in 3.16 with its axles in a non-retracted position.

3.17(5) 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.

3.18 Certifying results of SRT test

3.18(1) 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 in a form approved by the Agency.

3.18(2) 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); and
  • (ii) maximum safe gross mass to nearest tonne to meet SRT of 0.35 g (Y1); and
  • (iii) maximum allowable gross mass to nearest tonne (Y2); and
  • (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 3.17.

Section 4 Mass Limits

Section 6 Overdimension motor vehicles and overdimension loads

6.1 Application of this section

6.1(1) This section applies to—

• (a) a standard motor vehicle that is transporting an overdimension load; and
• (b) a specialist overdimension motor vehicle; and
• (c) a motor vehicle designed primarily to transport overdimension loads.

6.1(2) This section does not apply to—

• (a) a high-productivity motor vehicle; or
• (b) a motor vehicle that is being operated on a road or a portion of a road that is designated as a road construction zone under regulation 12 of the Heavy Motor Vehicle Regulations 1974, or that is a road works zone operated under a traffic management plan approved by a road controlling authority.

6.2 Responsibilities of operators of overdimension vehicles and loads

6.2(1) A vehicle in 6.1(1) must comply with the requirements in this section when operating on a road.

6.2(2) An operator of an overdimension vehicle or load that requires a permit under this section is responsible for ensuring that the vehicle used to transport the load is suitable and complies with the requirements of this Rule.

[Note: Overdimension vehicles have various constraints placed on them, which are determined by their category (determined by width and other dimension characteristics), the routes they use, and the time of day they travel. Generally, the larger the vehicle the more constraints imposed. Larger vehicles (in higher numbered categories) require permits from the Agency before they travel. ‘Overdimension load’ and ‘overdimension motor vehicle’ are defined terms.]

6.3 Classification of vehicles into categories

In this section, Category 1, Category 2, Category 3, and Category 4 are categories into which an overdimension vehicle is classified according to its width, forward-distance, length, front overhang, and rear overhang dimensions as specified in Part 1 and Part 2 of Schedule 6.

6.4 Certain vehicle configurations affect calculation of dimensions

6.4(1) If an overdimension motor vehicle is operated with a manned steering jinker or a pole trailer, the rear overhang is measured between the centre of the rear turntable load support and the rearmost part of the load.

6.4(2) If the vehicle combination includes a load-sharing trailer, the load-sharing trailer does not have to be included in forward-distance calculations if the forward-distance is 3.5 m or less. If the forward-distance exceeds 3.5 m, this distance must be added to the forward-distance of the main trailer, less 3.5 m.

6.4(3) If the vehicle combination includes a manned steering jinker, the forward-distance used for determining the vehicle’s category is half the distance between the two turntables supporting the load.

6.5 Standard motor vehicles transporting overdimension loads

6.5(1) A standard motor vehicle may transport an overdimension load that exceeds the dimension limits specified in Schedule 2, provided that the load—

• (a) is indivisible; and
• (b) is loaded in a way that minimises its width, unless the height or instability of the load, or both, make it necessary to transport the load widthways.

6.5(2) A standard motor vehicle may transport an overdimension load in addition to a divisible load, provided that the divisible load does not exceed—

• (a) a width of 2.55 m; or
• (b) a height of 4.3 m; or
• (c) the appropriate requirements for length or rear overhang in section 3 or Schedule 2.

6.5(3) A standard motor vehicle may transport more than one overdimension load, if the loads:
