The risk of a component (Note 2) 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 1) 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 1) 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 100 mm
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.
