3 Vehicle structure

3-1 Structure

Reasons for rejection

Mandatory equipment

1. An open-bodied vehicle that entered service as a PSV in New Zealand on or after 1 January 2001:

a) has side walls that are less than 450mm above the highest point of the uncompressed seat cushion on the open-bodied part of the vehicle, or

b) does not have a permanent framework in addition to the side walls to provide reasonable protection for the occupants in the case of the vehicle rolling over, or

c) on any upper deck does not have any drains to prevent water from collecting on it or draining into the body of the vehicle.

Condition

2. Refer to general vehicle pages.

3. The structural strength of a PSV has been reduced so that it does not provide reasonable protection for the occupants in the event of roof or wall deformation resulting from the vehicle rolling over, eg:

a) structural parts of the superstructure have been removed or substituted with parts that are of insufficient strength or not fit for purpose.

4. A body to chassis attachment, such as a weld, or fastener is:

a) missing, or

3-2 Stability

Reasons for rejection

Modification

1. A modification from 1 July 2000 affects the vehicle stability and:

a) is not excluded from the requirements for LVV certification (Table 3-2-1), or

b) is not for the purpose of law enforcement or the provision of emergency services, or

Table 3-2-1. Requirements for LVV certification

LVV certification is required

LVV certification is not required

1. Fitting of components to the roof, eg an air conditioning unit.

2. Changes in floor height or geometry, eg due to changes to suspension, wheel or tyre size.
