Registering a heavy vehicle

Heavy vehicle inspections

A heavy vehicle inspection scheme is vital for road safety. After multiple heavy vehicle crashes resulting in fatalities, a coronial inquest set out a series of recommendations, including the establishment of a heavy vehicle inspection scheme.

Heavy Vehicle Inspection Scheme – Change of Ownership

As of 1 January 2017 a Heavy Vehicle Inspection Scheme was introduced in South Australia when a heavy vehicle changes ownership. Stage one of the inspection scheme requires a vehicle inspection when changing ownership for all vehicles and trailers with a Gross Vehicles Mass (GVM) or Aggregate Trailer mass (ATM) over 4.5 tonnes that are three (3) years or older from date of manufacture.

This includes vehicles in the maintenance module of the National Heavy Vehicle Accreditation Scheme, but excludes buses that already undergo an annual inspection and special purpose vehicles such as tractors, agricultural and road making equipment.

The aim of the scheme is to confirm that the heavy vehicle at change of ownership, complies with Heavy Vehicle National Law and does not put the safety of other road users at risk.

For information regarding the standards your vehicle will be assessed to, you can refer to the National Heavy Vehicle Inspection Manual on the National Vehicle Regulator website.

Change of Ownership Inspections

Inspections for Interstate vehicles

A heavy vehicle purchased interstate must be inspected in South Australia, regardless of compliance with interstate inspection requirements.

Heavy vehicles three (3) years or older registered for the first time in South Australia, will require an identity and a roadworthy inspection for the transfer.

The identity inspection must be done first.

Information on locations for identity inspections can be found on the Interstate Vehicle Transfer page.

If the vehicle is going to be registered in SA as a multi combination vehicle (e.g. Road Train or B-double) or under a maintenance management scheme it also requires a roadworthy inspection that must be undertaken by DPTI; these inspections can not be undertaken by the private inspection stations.

Failed inspections at an authorised inspection station

If a fault has been identified during an inspection by an authorised inspection station, the vehicle will have a fail result recorded and cannot be transferred until the required repairs are completed and it passes. The vehicle’s faults can be repaired at the same location or at another repairer, depending on the nature of the faults.

Once the repairs are completed the vehicle will undergo another inspection at an additional cost. The person conducting the repairs cannot inspect their own work.

Depending on the faults and the degree of a component's deterioration the vehicle may be unsafe to be driven on the road. It is an offence to drive an unroadworthy vehicle on a road.

Disputed inspection at an authorised inspection station

If you believe that your vehicle should have passed a failed inspection, you should discuss your concerns with the person within the business that has the authority to resolve your complaint. Your complaint and action taken must be documented along with photos as supporting documentation. You should be given a copy of this documentation or at least the case number.

If the matter is not resolved and you aren't satisfied with the outcome, email the DPTI Audit and Compliance Unit with the case number and supporting details for further investigation. The investigation may also require your vehicle being inspected at a DPTI inspection station at an additional cost.

Inspections outside the Adelaide metropolitan area

For vehicles that will be registered in a country or rural area, change of ownership inspections are available through DPTI at an approved rural location by arrangement by contacting 13 10 84.

Alternatively, vehicles can be inspected at one of the authorised inspection stations in the metro area.


Inspection fees are set by the individual inspection stations and will be listed on their website, however they cannot exceed $268. Any subsequent inspection is considered a new inspection and will be charged accordingly.

The inspection is aimed at identifying faults that may compromise the safety of the vehicle and pose a risk to the driver or other road users.

Once a vehicle has passed a change of ownership inspection, the details are recorded on the DPTI Registration and Licensing computer system.

Frequency of inspection

Vehicles need to be inspected each time they are sold to allow transfer of registration into the new owner’s name. A passed inspection is valid for three calendar months from the time of inspection.

Vehicles requiring annual roadworthy inspection

The following vehicle types require an annual roadworthy inspection:

  • A vehicle which is part of a road train or b-double, or a combination, including its load (if any), that is over 19 metres long or has a total mass over 42.5 tonnes that is not part of a National Heavy Vehicle Accreditation Scheme - condition of route access
  • A bus (13 seats or more) - legislative requirement
  • Federally Registered Vehicles

Defect clearance

  • If the vehicle has been issued with a defect notice it must be cleared as recorded on the defect notice.
