Large base radio antennas
You should only mount large base radio antennas on the front of you vehicle if it is impossible or impractical to install the antenna to the rear of the vehicle.
The antenna must be attached to the left side and as low as possible.
Only one large base antenna may be fitted to the front of the vehicle. The maximum diameter permitted is 75mm.
The antenna must not:
- have any sharp edges or protrusions
- obscure any light - additional lights must be fitted or the original light relocated if a light is blocked.
A bicycle carrying rack is usually fitted to the tow bar or boot of a vehicle, or the roof rack.
You must do all of the following:
- attach the bicycle rack according to the manufacturer's instructions
- make sure welding on the bicycle rack fits with Australian standards
- secure the tow bar or roof rack and its load
- secure the bicycle to the rack
- make sure the the bicycle rack is free of sharp edges and protrusions.
Rules for fitting a bike rack
You must make sure the bicycle rack and its load does not do any of the following:
- project excessively behind the rear of the vehicle
- exceed rear overhang limits (60% of the vehicle's wheel base)
- protrude more that 150mm beyond the extreme width of either side of the vehicle
- block any vehicle lights
- block the driver's vision of the rear of the vehicle
- block the number plate.
If the bike rack blocks the view of the number plate you can re-locate the number plate, or place an additional number plate onto the bicycle rack.
You will have to pay a fee for the extra number plate, and it must be identical to the number plate on the vehicle.
You should also remove the bike rack from your vehicle when not using it to carry bikes.
Bonnet scoops or projections may be fitted to a vehicle provided the driver's vision is not restricted.
Bonnet-mounted scoops or projections must meet the following requirements:
- When a 165mm diameter sphere is placed on the bonnet in front of the scoop (or bonnet projection) and rolled backwards until it touches the scoop, no forward point of the scoop or point of contact between the sphere and the scoop must lie above a horizontal plane passing through the centre of the sphere.
- It must be possible to see either the surface of the road 11m in front of the driver's eye or all of the front edge of the body when looking across the top of the bonnet scoop.
- The edges at the front of a scoop must be well rounded with a minimum of 10mm radius.
- The scoop must not have reflective surfaces that will cause glare towards the driver.
- A bonnet scoop manufactured from a plastic or fibre glass material may be fitted, providing that the hole in the original bonnet does not reduce the strength or impact resistance of the bonnet or a rigid component – eg: an air cleaner or carburettor.
- Holes may be cut in the bonnet and the protrusion of an air cleaner or carburettor above the bonnet line, but below the bonnet scoop providing that the bonnet scoop or raised bonnet section is manufactured from equivalent gauge mild steel, compared with that of the original bonnet.
- If any bonnet reinforcing braces are cut or modified, the design of the modified bonnet must be of equal strength to the original bonnet and any sharp edges created must be suitably treated.
- All edges and corners shall have a radius of not less than 5mm and of general design and construction to reduce to a minimum the risk of bodily injury to any person.
Bull bars must be designed and fitted so that the safety of the vehicle is not adversely affected.
A bull bar must include all of the following:
- securely mounted and supported
- free of sharp protrusions and all exposed sections of the bull bar and fittings must be radiused and de-burred
- have extra lights fitted, according with Australian Design Rules, if it obscures any light
- matte black on surfaces that could reflect light from the vehicle's headlights.
It must not be any of the following:
- a danger to other road users
- obstruct the vision of the driver
- project further from the front of the vehicle than is necessary for its attachment. Bull bars should not add a significant load to the front suspension.
- obscure any light – including indicator lights at all viewing angles.
Vehicles fitted with an airbag or manufactured with full frontal impact occupant protection must only be fitted with a bull bar that has been:
- certified by the vehicle manufacturer as suitable for that vehicle
- or certified by the manufacturer as complying with the Australian Design Rules and doesn't interfere with the airbag timing mechanism.
Bull bars that comply with Australian standards 4876.1-2002 provide a higher level of pedestrian protection.
Fishing rod holders
When fitting a fishing rod holder you must follow all of the below:
- the fitting allows the driver to see the road and traffic to the front and sides of the vehicle
- the vehicle's lighting isn't obstructed by rods or holders
- rod holders are either removed when they are not in use or retracted behind the bull bar with no protruding surfaces.
Any additional internal or external gauges must be safely fitted and not do any of the following:
- interfere with the field of view of the driver
- produce glare to the driver
- have the possibility of an oil pressure line breaking with pressurised fluids spraying onto the windscreen.
Roof racks (ladder racks)
Rules for fitting a bike rack
Ladder racks positioned forward of the windscreen should not do any of the following:
- project more than 150mm from each side of the vehicle or make the vehicle more than 2.5m wide
- obscure any lights – or an additional light must be fitted or the original light must be relocated
- have any sharp edges or protrusions on supports, braces and brackets
- interfere with a person's access to the vehicle.
Ladder racks should be removed when not in use.
Side skirts, flares and spoilers
Side skirts, front and rear spoilers may be fitted provided road clearance and air flow for brake cooling is not affected.
They must not be fitted so that it is likely to increase the risk of bodily injury to any person.
All material is to be of a suitable thickness and be free from sharp edges or corners.
Rear spoilers must be within the body shape or outline of the mounting surface – eg: boot outline.
The minimum thickness of end plates is 4mm and they must be free of sharp edges or corners.
Visual display screens
DVD screens, television receivers and visual display units can be installed in a vehicle according to the manufacturer's instructions or Australian Standards.
