2 Vehicle exterior
2-1 External projections
Reasons for rejection
Condition and performance
1. The risk of a component (Note 5) hooking a vehicle, or hooking or grazing a person, has not been minimised, eg a bonnet or bumper has been removed, exposing sharp, moving or hot components.
2. An ornamental object or fitting (Note 2) protrudes in such a way that it is likely to injure a person.
3. A protruding object or fitting that has a functional purpose (Note 3) is not installed so that the risk of causing injury to a person is minimised, eg the object or fitting:
a) is of excessively heavy construction for the purpose for which it has been fitted, or
b) has sharp corners, or
c) slopes forward, unless this is necessary to fit the contours of the vehicle, or
d) has an unnecessarily wide gap between the object or fitting and the front of the vehicle, or
e) exceeds the vehicle’s width by more than 100mm on either side, other than side mounted glass sheet transport racks and collapsible side mirrors, or
f) is a glass sheet transport rack that is not fitted with a front flaring to minimise the risk of injury to a person.
4. A protruding component, object or fitting is not securely attached to the vehicle.
5. A protruding object or fitting adversely affects the driver’s vision or control.
Modifications
6. A modification (Note 4) affects an external projection – including a protruding object or fitting that has a functional purpose and affects the driver’s vision or control of the vehicle, and
a) is not excluded from the requirements for specialist certification (Table 2-1-1), and
b) is missing proof of specialist or accepted overseas certification, ie:
i. the vehicle is not fitted with a valid vehicle certification plate (eg low volume vehicle plate or heavy vehicle certification plate/label), or
ii. the operator is not able to produce a valid modification declaration or authority card
iii. the vehicle has not been certified to an accepted overseas system as described in Technical bulletin 13 .
Note 1
The external projections requirements relate to the design and maintenance of objects and fittings that protrude from the exterior of the motor vehicle with regard to the safety of other motor vehicles, pedestrians and cyclists. The attachment of such objects and fittings to the vehicle is addressed in the Vehicle structure section of this manual.
Note 2
Ornamental object or fitting means an object or fitting that does not have a practical purpose, eg bonnet emblems.
Note 3
Functional object or fitting means an object or fitting that has a practical purpose, eg panniers, pack racks, spare wheel carriers, and so on.
Note 4
Modify means to change a vehicle from its original state by altering, substituting, adding or removing any structure, system, component or equipment, but does not include repair.
Repair means to restore a damaged or worn vehicle, its structure, systems, components or equipment to within safe tolerance of its condition when manufactured, including replacement with equivalent undamaged or new structures, systems, components or equipment.
Note 5
Components include damaged, corroded and exposed body panels.
Note 6
The following vehicles with a GVM of 2500kg or less must comply with a frontal impact occupant protection standard:
- Class MA motor vehicles manufactured on or after 1 March 1999
- Class MA motor vehicles that were less than 20 years old when they were first registered in New Zealand on or after 1 April 2002
- Class MB and MC motor vehicles manufactured on or after 1 October 2003.
Note 7
Rear bumper removal must still meet external projection requirements.

Summary of legislation
Applicable legislation
Permitted equipment
1. A motor vehicle may be fitted with a protruding ornamental or functional object or fitting.
Condition and performance
2. A protruding ornamental object or fitting must not be likely to injure a person.
3. A protruding object or fitting that has a functional purpose must be installed so that the risk of the object or fitting causing injury to a person is minimised.
4. Components of a motor vehicle, including damaged or corroded body panels, must be such that the risk of their hooking a vehicle, or hooking or grazing a person, is minimised.
5. A protruding object or fitting must not adversely affect driver vision or driver control.
Modifications
6. A modification that affects an external projection must be inspected and certified by a specialist certifier, unless the vehicle:
a) is excluded from the requirement for specialist certification (Table 2-1-1), and
b) has been inspected in accordance with the requirements in this manual, including those for equipment, condition and performance.

2-2 Dimensions
Reasons for rejection
Mandatory requirement
1. A rigid vehicle (Note 1) with a GVM of 3501kg or more exceeds the dimension requirements set out in Table 2-2-3 and is not a vehicle operating on a valid permit, exemption or approval.
2. A bicycle rack on a public transport vehicle of class MD3, MD4 or ME is:
a) not centrally mounted from the longitudinal centre of the vehicle, or
b) more than 1200mm from the forwardmost point of the vehicle, or
