Tray mudguard question

Post by ausyota »

Does a ute tray need guards on the front of the tyre like all your crappy off the shelf traybacks to be legal?
Or does it just need to cover the top and rear?
This is a pic of my tray do I need a front guard as shown in red?
Cheers
Paul.

yes

the majority of trays i've seen do have those front bits - the one's that don't have them are custom built, or have been ripped off on a rock/similar :lol:

15.2 Wheel Guards for Vehicles other than MA and
L-group Vehicles
15.2.1 General Requirements
All wheels of a motor vehicle or trailer (including a
‘Prime Mover’ capable of operating without a ‘Semitrailer’)
must be provided with wheel guards which
must be so designed as to protect other road users, as far
as practicable, against thrown-up stones, mud, ice, snow
and water and to reduce for those users the dangers due
to contact with the moving wheels.
15.2.2 Special Requirements
The wheel guards on the rearmost wheels on vehicles
other than MA and L-Group vehicles must provide
continuous protection between a point in area A and a
point in area B in Figure 2, and must be provided for the
‘Overall Tyre Width’ of all tyres.
15.2.2.1 In the case of steerable wheels, the
requirements of clause 15.2.2 must only apply when the
wheels are in the straight-ahead position.
15.2.3 Wheel guards may consist of either permanent
body structure or part structure and other components,
including mudflaps, provided the specified protection is
retained during vehicle operation.
15.2.4 Where 2 or more ‘Axles’ form an ‘Axle Group’,
separate wheel guards may be provided for each rear
wheel or a single wheel guard may be provided which
provides continuous protection from area ‘A’ of the
foremost wheel to area ‘B’ of the rearmost wheel in
Figure 2.
15.2.5 Notwithstanding the requirements specified
above the wheel guard including a mudflap (if fitted)
need not be less than 230 mm from the ground for other
ADR 42/02 GENERAL SAFETY REQUIREMENTS
ADR 42/02 6 of 12 As at Det. No. 2 of 1995
than off-road vehicles, or 300 mm in the case of
vehicles designed for off-road operation.
15.2.6 The requirements of this part do not apply to any
vehicle the construction or use of which is such that, in
the opinion of the ‘Administrator’ it is unnecessary or
impracticable to provide a wheel guard(s).

not sure wether they classify your vehicle as a

Passenger Car (MA)

or an Offroad Passenger Vehicle (MC)

Pretty sure Passenger vehicles are buses etc, not hilux/landcruisers which are Passenger Cars.

I am terying to find the specification for MA and L type vehicles.

15 WHEEL GUARDS (MUDGUARDS)
15.1 Wheel Guards for Passenger Cars (MA)
Vehicles Only
15.1.1 General Requirements
The vehicle must be provided with wheel guards (parts
of the bodywork, mudguards, etc.) which must be so
designed as to protect other road users, as far as
practicable, against thrown-up stones, mud, ice, snow
and water and to reduce for those users the dangers due
to contact with the moving wheels.
15.1.2 Special Requirements
15.1.2.1 The wheel guards must meet the following
requirements when the wheels are in the straight ahead
position:
15.1.2.1.1 in the part formed by radial planes at an
angle of 30 degrees to the front and 50 degrees to the
rear of the centre of the wheel (see Figure 1), the overall
width (q) of the wheel guards must be at least sufficient
to cover the tyre ‘Section Width’ (b) of the tyres fitted to
the vehicle taking into account the extremes of
tyre/wheel combination as specified by the
‘Manufacturer’;
15.1.2.1.2 the rear of the wheel guards must not
terminate above a horizontal plane 150 mm above the
axis of rotation of the wheels (as measured at the wheel
centres) and furthermore the intersection of the edge of
the wheel guard with this plane (point A, Figure 1) must
lie outside the median longitudinal plane of the tyre;
15.1.2.1.3 the contour and location of the wheel guards
must be such that they are as close to the tyre as
possible; and in particular within the part formed by the
radial planes referred to in clause 15.1.2.1, they must
satisfy the following requirements:
15.1.2.1.3.1 the projection - situated in the vertical
plane of the tyre axis - of the depth (p) of the outer edge
of the wheel guards, measured in the vertical
longitudinal plane passing through the centre of the tyre,
must be at least 30 mm. This depth (p) may be reduced
progressively to zero at the radial planes specified in
clause 15.1.2.1.1; and
15.1.2.1.3.2 the distance (c) between the lower edges
of the wheel guards and the axis passing through the
centre of the wheels must not exceed 2r, ‘r’ being the
‘Static Loaded Tyre Radius’ of the tyre;
15.1.2.1.4 in the case of vehicles having adjustable
suspension height, the above mentioned requirements
must be met when the vehicle is in the normal running
position specified by the ‘Manufacturer’;
15.1.2.1.5 the wheel guards may consist of several
components, provided that no gaps exist between or
within the individual parts when assembled; and
15.1.2.1.6 the wheel guards must be securely attached.
However they may be detachable either as a unit or in
parts.

not sure which you need to comply with, but the top one is easier to understand.

You need a mudguard from 30degrees forward round to 20 degrees from the ground, but no more than 300mm off the ground.

The MA specification says the mudguard must be no more than 2r from the centre of the wheel (31 inch tyre, mudguard must be no more than 31inches from the centre of the wheel).

If your vehicle is an MA (Passenger Car) then then you definantly need a forward guard, if not then you could argue that the tray itself covers the wheel to 30degrees forward of the verticle axis of the wheel.

Hey Ausyota, nice looking tray! I'm in a similar situation as I have no wheel arches / mud guards / mud flaps over my rear wheels on my Hilux. I've been driving like that for about 9 months and haven't been pulled over by the police yet. Any chance you could show a close up pic of how your mudflaps are mounted to the tray.

Nah no close up pics of the flaps.
The top of the flap is rubber so it works like a bit of a hinge if it hits something. It is just bolted with 2 bolts through the rubber into a length of angle iron under the tray and the chain is attached with a little shackle to a chain link welded under the tray.
takes about 1 minute to pull them both off for offroad/comps.
