Seat belt webbing must be firmly secured to its end fittings and must not be damaged, cut, knotted or frayed. Repairs or modifications to webbing, buckles, retractors or other seat belt components are not permitted.
Lighting requirements (lamps, reflectors and marking plates) vary substantially with the type of vehicle and its date of manufacture.
For newer vehicles and optionally for older vehicles, details of the requirements together with the type, number, location, colour, operation and adjustment of lamps and reflectors are set out in the Third Edition Australian Design Rules (ADRs). Alternatively, for vehicles not required to meet the Third Edition ADRs, the requirements specified in the Standards for Registration for that particular type of vehicle should be applied.
Generally, all motor vehicles must be fitted with headlamps, stop lamps, front and rear position lamps, a number plate lamp and turn signal lamps. All other vehicles (trailers etc.) require rear position lamps, stop lamps, a number plate lamp and turn signal lamps.
In addition to these lamps, a number of other lamps such as work lamps, auxiliary driving lamps, front and rear fog lamps, reversing lamps, external cabin lamps, clearance lamps, marker lamps, daytime running lamps and front lamps on sidecars are either required or permitted. Hazard warning lamps are required on certain buses and late model vehicles.
Vehicles must not be fitted with lights or reflectors not required or permitted by the Standards for Registration or the ADRs.
All mandatory internal warning lamps, including the airbag check lamp where fitted, must function correctly. In buses, lamps used for stairwell lighting are mandatory lamps.
All lamps fitted to a vehicle, including any optional lamps but excluding undipped headlamps, ancillary driving lamps and work lamps, must be fitted with lenses or otherwise shielded so that the light emitted does not cause glare. All lenses must be of the correct colour, not substantially faded and must be clean on the inside and free of any damage, which would permit dust or water to enter the lamp. Headlamp reflectors must be in good condition.
The presence of minor condensation on semi sealed lamps is acceptable.
All lamps must be securely mounted and correctly orientated.
Reflectors must be functional, of the correct colour and securely mounted.
Portable warning devices on tow trucks must be of an approved type and not deteriorated to an extent which reduces their effectiveness.
Rear marking plates must not be faded or deteriorated and must be of the correct type and correctly located.
Some vehicles, due to the nature of their use, require additional or special lighting or lighting located in non complying positions. These vehicles will usually belong to Police, Emergency, Road Maintenance or other similar organisations.
Other vehicles owned by private organisations requiring special lighting may be allowed to fit the lighting under conditional registration provisions.
The exhaust system of a vehicle must not pass through the cabin or any passenger area and must be free of leaks. Condensation drain holes are not leaks.
The exhaust system must be fitted with an effective silencing device and all exhaust gases must pass through the device.
All mountings must be secure and the exhaust system must have adequate clearance between all other parts of the vehicle and the road.
Unshielded parts of an exhaust system, other than the outlet, must not protrude beyond the profile of the vehicle other than on the underside. The outlet must be located so as to avoid direct entry of gases into the passenger compartment and must not extend beyond the plan of the vehicle. See VSI 8 for more information on exhausts.
Vehicles manufactured to comply with emission control ADRs must have all pipes, hoses, valves, sensors, fuel and air control devices and any other emission control equipment originally fitted by the vehicle manufacturer properly located and connected and not apparently damaged, deteriorated
or altered in any way so as to appear ineffective.
Dual fuelled vehicles must retain any emission control equipment fitted to enable them to meet emission requirements while operating on petrol.
However, allowances are made for minor air cleaner and carburettor modifications required to fit the conversion. The heated air intake system can be removed and the air cleaner replaced with one to suit the LPG conversion.
For vehicles fitted with a four-stroke engine, exhaust emissions (except for water vapour) must not be visible to the naked eye for more than 10 seconds under normal operating conditions. When running, the engine must not discharge excessive crankcase fumes and where crankcase ventilation equipment is fitted it must be secure and leak free.
The exhaust outlet on a diesel engine vehicle with a GVM over 4.5 tonne and manufactured after 1976, other than a bus, must be at least 3m above the ground. The outlet must discharge upwards either:
within 30° of the vertical and to the rear within 45° either side.
If a vertical exhaust outlet is fitted with a rain cap it must be hinged at approximately 90° to the centerline of the vehicle.
Note: This vertical exhaust requirement does not apply to some special purpose vehicles; or
Vehicles certified to meet the vehicle emission standards specified in ADR 80/01 published by the Australian Government Department of Infrastructure, Transport, Regional Development and Local Government and have a horizontal exhaust that discharges on the driver’s side of the vehicle towards the centre of the road.
Crankcase ventilation recirculation equipment is required on petrol engine vehicles (other than motor cycles)
built after 1971.
Nitrous oxide systems are not acceptable on motor vehicles used on the public roads.
All glazing used in a motor vehicle built after June 1953 is to be safety glass or other approved material. The glazing that is necessary to allow the driver to see the road and other road users is not to be damaged or altered to the extent that it prevents the vehicle being used safely.
Wear or Damage
During the service life of a vehicle, the windscreen and windows may incur various types of damage. Testers are advised that deterioration from the as new condition is allowable and a windscreen or window with minor damage should not be rejected.
A windscreen should only be rejected if;
it is discoloured, badly scratched, fractured or chipped within the area wiped by the windscreen wiper(s) to the extent that the drivers vision is so impaired that the vehicle cannot be driven safely; or,
in the case of a laminated windscreen, it has any crack that penetrates more than one layer of glass, or
in the case of a laminated windscreen, it has one or more bulls eyes or star fractures over 16mm in diameter or one or more cracks over 150mm in length in a single layer of glass within the area wiped by the windscreen wiper(s). One or more bulls eyes or star fractures up to 16mm in diameter and cracks up to 150mm in length
in a single layer of glass within the area wiped by the windscreen wiper(s), are allowable provided that they do not impair the drivers vision to the extent that the vehicle cannot be driven safely.
Side windows that are scratched or otherwise damaged to the extent that the driver’s vision is so impaired that the vehicle cannot be driven safely should also be rejected.
Where signaling devices are not provided, the driver’s side window must be capable of being opened or some other means provided to give hand signals.
Repairs and Obstructions to View
In a repaired windscreen a faint outline of the repaired damage or in some cases a slightly dull spot may be visible where the repair has been performed. A repaired crack may also be detectable by a fine hairline surface mark. These are acceptable and should not be rejected during a roadworthy test providing the rest of the windscreen complies with the requirements as set out in this section.
Apart from any pillar or other part of the vehicle’s structure or fittings, there must be no internal obstructions to a driver’s view through the swept area of the windscreen, to the
right of the driver’s position or 60° to the left of the driver’s position, except for the area outside the primary vision area.
The primary vision area of the windscreen of a vehicle may be lightly tinted to achieve a light transmittance of no less than 75% if the vehicle was made after 1971, or 70% if made earlier. Tinting in the primary vision area must have been incorporated during the manufacture of the windscreen and not by coating or tint films added afterwards.
Any tinting applied to the windows of a vehicle after it has been manufactured must comply with the requirements specified in VSI 2 (Window Tinting).
Primary Vision Area
For cars and other light vehicles, the primary vision area can be approximated by excluding the area above the wiper arc or the top 10% of the windscreen, whichever is the greater. For heavy vehicles with large windscreens, exclude the area above the wiper arc or above a horizontal line 200mm above the height of the driver’s eye when seated in the normal seating position, whichever is the greater, and the area below the top of the steering wheel when looking from the driver’s seat in a normal seated position.
All motor vehicles (except motorcycles) fitted with a windscreen must be fitted with an effective windscreen wiper system. If manufactured before 1960 then the
wiper need only be fitted to the driver’s side. On vehicles where the windscreen is such that a driver, in the normal driving position, can obtain adequate vision of the roadway ahead by looking over the top, below or to a side of the windscreen, a windscreen wiper system is not required.
If the vehicle is one required by the standards or the ADRs to have a windscreen washer system then the system must be fitted and work effectively.
All motor vehicles manufactured on or after 1 September 1966 and required to be fitted with a windscreen wiper system must be fitted with an effective windscreen washer system.
Both the windscreen wiper system and the windscreen washer system must be capable of being operated by the driver from the normal driving position.
All components of both systems must be secure, functional and not excessively worn. Windscreen wiper blades must only sweep over the windscreen glass and not contact any other component to an extent which could affect their performance while in operation.
Windscreen washer jets must be correctly aimed.
Vehicles required to comply with demisting provisions (e.g. ADR 42 and certain buses) must have the necessary equipment present and operational.
All mountings, brackets and fastenings necessary for the safe operation of the vehicle must be secure and free from damage, deterioration or abnormal distortion. All shafts, splines, universal joints, support bearings, tail shaft guards and other drive line components must be in good condition and free of excessive wear and vibration.
The power unit, clutch system, transmission system, differentials, axle housings and all associated pipelines must be properly sealed and free of dripping or flowing oil leaks onto the roadway, exhaust system or brake friction surfaces. Dampness, weeping or staining are acceptable but oil leaking from the underside of the vehicle to such an extent that it is likely to drop oil on the road surface (if the vehicle is parked or idling stationary for any length of time) is unacceptable.
Any insulating material in an engine enclosure must be in good condition and free from contamination by fuels or lubricants and there must not be any accumulation of fuel or lubricant in engine compartments.
The Standards for Registration detail requirements for LPG vehicles.
A LPG system fitted to a vehicle must comply with the requirements of the Australian Standard AS 1425 applicable at the date of the installation. If the date of installation is not known, the age of the vehicle and LPG tank date stamp may be used in determining the date of installation.
The LPG system must be free of leaks and all components secure and free from damage and deterioration.
The periodic inspection requirements of Australian Standard 1425 should be used when carrying out a roadworthy inspection on a vehicle fitted with LPG.

Any vehicle designed primarily for the carriage of goods or any vehicle subject to internal rear vision obstruction must be fitted with external rear vision mirrors on both sides of the vehicle.
All rear vision mirrors must be securely and firmly mounted and capable of appropriate adjustment. The reflective surface must not be cracked or broken nor peeled, tarnished, discoloured or deteriorated to such an extent that its effectiveness is reduced.
On all vehicles subject to ADR 14, except motorcycles,
any internal vision mirror must be flat. However, additional curved mirrors may also be fitted, either independently or on standard mirrors. If fitted on a standard mirror they must not occupy a substantial part of the reflective surface of the standard mirror.
All motor vehicles must be fitted with one or more effective horns or other audible warning device, which produces a steady sound of constant pitch.
Fuel tanks must be securely mounted and the fuel system including fuel lines and filler pipes must not project beyond the widest part of the vehicle.
Additional or replacement fuel tanks must be at least of an equivalent standard to the original tanks and not affect the vehicle’s compliance with evaporative emission or other provisions.
All fuel lines, vent lines, pumps, valves and fittings must be secure, free of leaks, adequately protected from damage and must not chafe or rub against each other or other parts of the vehicle.
Fuel filler caps must be secure and seal properly. Plastic emergency fuel filler caps are not acceptable.
The structural components of all vehicles must be sound and free from cracks, damage, faulty repairs or modifications, rust, deterioration, distortion or any other condition which could lead to structural failure of the vehicle or adversely affect the performance of safety related features.
In some buses, extensive corrosion may be hidden by inner and outer body panels necessitating panel removal or other means to determine the extent of structural deterioration.
The body and fittings of all vehicles must be free from any damage, which might increase the risk or severity of injury to any occupant, pedestrian or other road user. The body must also be free of any damage likely to allow the entry of exhaust gases into the passenger area. All seals at body openings necessary to prevent the entry of exhaust gases into any passenger area must seal effectively.
Floors including floors in load areas must be in a sound condition. Floors in passenger areas must be free of loose material or objects or tears, or incorrectly fitted matting, or covering likely to interfere with the driver’s ability to safely operate the vehicle. In buses, floors and steps must have a suitable non-slip surface.
Where a bus is more than 25 years old, proof of a current acceptable structural assessment must be provided and sighted by the tester.
Where a bus is fitted with a luggage rack or racks, there must be no projections that could cause injury to passengers and the rack or racks are to be adequately secured and prevent movement of luggage during normal braking and cornering manoeuvres.

The warning devices provided on all emergency exits other than service doors and breakable glass emergency exits must be present and serviceable.
The warning must be given when the engine is started and/ or vehicle is in motion, if:
the primary opening or ejection device is moved;
an emergency exit is locked from the outside; or
an emergency door or window is not securely closed.
The warning device must provide a visible and audible warning to the driver and must activate with movement of the catch or other device securing the emergency exit, not only by movement of the emergency exit itself.
Effective wheel guards must be fitted for all wheels on all vehicles except front wheels on mopeds and motorcycles manufactured before 1 July 1988. Wheel guards may include parts of bodywork, etc. Wheel guards must cover the full width of the wheels and tyres in the case of rear wheels on trucks, buses and trailers.
Mudflaps are not normally required on passenger car type vehicles. However, mudflaps must be in place on vehicles where they form part of the wheel guard system such as on some motorbikes, heavy vehicles and vehicles with a tray type body.
Prime movers must also comply with the wheel guard requirements. However, the guards over the rear wheels may be of a flexible material provided they are adequately supported.
Flexible wheel guards or mud flaps must retain their functional position when the vehicle is in motion.
For passenger cars the tyre section width at the top of the tyre must be covered when the wheels are in the straight- ahead position. For motorcycles, sidecars and trikes, guards must cover the tyre section width.
Relaxed wheel guard provisions may apply to some special purpose vehicles, such as timber jinkers.
Bumper Bars/Bull Bars
Bumper bars and bull bars, where fitted, must be secure and designed to eliminate sharp corners or protrusions, which might cause injury to other road users. They must not obscure any lamps, unless additional lamps are fitted, and must not substantially exceed the normal width of the vehicle body. ADRs and VicRoads information sheets cover visibility angles of lamps. Ends of bumper bars must turn towards the body to a sufficient extent to avoid any risk of hooking or grazing.
Any towbars, eyes, hooks, turntables or automatic couplings fitted to a vehicle must be in good condition, secure and not cracked, excessively deformed or damaged in a way likely to cause failure. All electrical wiring, connectors, couplings, flexible pipes, etc associated with a device for coupling a trailer to a motor vehicle must be in good condition.

The battery must be adequately supported and secure.
In addition, if fitted in a luggage or occupant compartment, the battery must either be of a type that is fully sealed or be located within a sub-compartment which is vented to atmosphere outside the vehicle.
Vehicles with batteries located in the same way as that used by the vehicle manufacturer as original equipment are deemed to comply with this requirement provided the battery is of the same type as the original and its installation and related components are as per the vehicle manufacturer’s specification.
Tow trucks, buses, motor homes and caravans subject to ADR 44 or ADR 58 must have the correct number and type of extinguishers fitted in an accessible location and the extinguishers must be in a serviceable condition.
Visual Display Units (VDU)
Any Visual Display Unit that is visible to the driver from the normal driving position should be rejected if it does not:
Switch off the visual display while the vehicle is in motion; Function as a driver’s aid while the vehicle is in motion; or Meet the field of view requirements as specified in VSI 29.
Examples of driver’s aids:
- Closed-circuit television security cameras. Dispatch systems.
- Navigational or intelligent highway and vehicle system equipment.
- Rear view screens. Ticket-issuing machines. Vehicle monitoring devices.
Additional equipment fitted to the interior or exterior of a vehicle must not present an undue risk to occupants or others.
Optional and Non Essential Equipment
Where optional and non essential equipment is fitted such as air conditioning, rear window demisters, etc, it is not necessary for it to work providing it does not adversely affect the safety of the vehicle or its compliance with mandatory Standards for Registration.
All gas and electrical installations must be certified to the relevant Australian Standards as specified in VicRoads’ VSI 5 Conversion of Vehicles to Motor Homes.
Modifications to vehicles fall into two broad categories:
- Those covered by guidelines published in VicRoads Vehicle Standards Information sheets; and
- Those which require individual approval and thus an approval certificate from a VASS.
This makes it difficult to determine whether the modification has been approved in the context of a roadworthiness inspection.
In these circumstances an examination should be confined to checking that the modification appears to be properly executed and not in a condition which presents a hazard.
See VSI 8 for more information on modified vehicles.
Identification plates were required on vehicles manufactured after June 1988 as evidence that, at the time of first registration, the vehicle complied with the applicable ADRs. However, identification plates are often damaged, lost or stolen during the life of the vehicle. Therefore, the presence of an identification (compliance) plate is not a mandatory requirement for the issue of a Certificate of Roadworthiness.
Similarly VASS approval certificates are generally supplied as evidence at the time of registration or change of description that the vehicle complies with the applicable standards for registration.
A VASS approval certificate should only be requested by a Licensed Vehicle Tester, when a vehicle modification, which affects handling, structural integrity or compliance with the standards for registration, does not appear to comply with good industry practices.
Additional inspection standards for Buses.
The inspection standards in this section apply to Buses subject to the Bus Safety Regulations 2010 as in force from time to time.
Where a bus is fitted with door interlocks, the interlocks must be serviceable.
Internal Mirrors or CCTV
Internal mirrors or CCTV used to provide the driver with
a view of passengers in or on the bus must be serviceable and functioning.
Maximum Safe Carrying Capacity Signs/Notices
Maximum Safe Carrying Capacity signs/notices on buses with seating positions for 13 or more adults, including the driver, which display the maximum number of passengers that may be safely carried on that bus, must be in good condition and legible.
(Requirements regarding the number, size and location
of the signs/notices are detailed on Transport Safety Victoria’s website: transportsafety.vic.gov.au/bus-safety/ bus-operators/maximum-number-of-passengers)
Buses with a Gross Vehicle Mass of more than five tonnes that are being inspected for the purposes of the bus annual safety inspection requirements in the Bus Safety Regulations 2010, Part 5, Regulation 23 must be subjected to a Roller Brake Test in accordance with the standard below.
The Roller Brake Tester used to conduct the test must comply with Australian/New Zealand Standard AS /NZ 4613: 1999 Automotive Brake Testing equipment – Roller Brake Tester or a similar ISO standard such as ISO 21995. Roller brake testing must be conducted in accordance with section 1.13 of the National Heavy Vehicle Inspection Manual - December 2004 published by the National Transport Commission (www.ntc.gov.au) and the roller brake tester manufacturers instructions.
The vehicle must achieve a:
- Minimum brake force of 3kN/tonne (0.3 g) determined by adding the measured brake force for each axle and dividing it by the mass of the vehicle as tested; and
- Maximum brake drag of 1.0 kN for each drive axle and 0.5 kN for each other axle; and
- Maximum difference in brake force between the wheels of the same axle of 30%, for each axle of the vehicle.
A Roller Brake Tester may be used to determine the deceleration rate of the vehicle provided:
- the brakes are warm when tested; and
- each axle of the vehicle has been loaded to at least 50% of the legal load limit or 50% of the manufacturer’s rated load limit if below the legal limit or provided that at least one third of the guaranteed air pressure can be obtained at the brake actuator.
The results of the Roller Brake Test are to be printed and attached to the RWC or to the RWC test report provided to the operator or the operators representative if a RWC is not able to be issued.
The Roller Brake Test must be conducted no more than seven days prior to the date of the roadworthiness inspection.
This test applies in addition to all the other roadworthiness standards set out in VSI 26 , with the exception of determining the deceleration rate of the vehicle, if a roller brake tester is used to determine the deceleration rate.
