Specialty harnesses and vests

A specialty harness or vest is an accessory product that is sold separately to vehicle restraint products, often used to support postural needs or occupants who try to get out of their vehicle restraint.

In some instances, yes. However our buckle release project found there is a broad range of challenges relating to motor vehicle passengers getting out of their vehicle restraint. It is important to assess the person's individual needs and identify all restraint types that may support keeping them safe and comfortable during transport.

The NDIS Commission’s position, as outlined in their Safe Transportation Practice Guide is that a harness prescribed for postural/therapeutic support is not considered a regulated restrictive practice, regardless of whether the person is also engaging in behaviours of concern.

However, using a harness on a person to manage a behaviour of concern in a vehicle, who does not require it for postural/therapeutic support is considered a regulated restrictive practice.

No. Only some importers/suppliers of specialty harness/vests have registered these products with the Therapeutic Goods Association as a medical device for postural support.

Yes. There are forward facing car seats with built-in harnesses. This type of Australian standard car seat complies the the Australian standard for child restraints (AS/NZS 1754) and is suitable for 50 per cent of children up to at least 10 years of age (labelled as suitable from 6 months to 8 years of age).

Until recently, there was no Australian standard for specialty harness/vests.

‘AS 5384: Accessories for seat belts used in motor vehicles’ was published in September 2023 and caters for the design, safety and performance of postural device, such as specialty harness/vests.

The standard includes requirements for crash testing, labelling and packaging.

This provides suppliers in the Australian market with an opportunity to develop and supply products that comply with the relevant section of this new standard.

MACA led an Austroads project, in partnership with The George Institute for Global Health, to research and investigate specialty harnesses/vests for both Australia and New Zealand.

The Austroads report was published in March 2025 and includes recommendations for the safe selection and use of specialty harness/vests aimed at prescribers. These recommendations require the development of guidance materials, as recommended in the report.

Further research is also recommended to investigate the selection and use of specialty harnesses/vests in supported school buses. MACA is seeking funding to progress these recommendations.
