## How SA certification works

South Australia recognises engineering signatories to assess modified light vehicles against VSB14 plus SA-specific requirements. The signatory produces an engineering report that is lodged with the Department for Infrastructure and Transport and attached to the vehicle's registration record.

## Check the signatory's scope first

As in every jurisdiction, signatories are recognised for particular categories of work. Confirm the signatory covers your modification type — engine, brakes, suspension, seats — before booking an inspection.

## VASS recognition

South Australia generally accepts Victorian VASS certificates, which makes SA one of the easier destinations for an engineered Victorian car. Carry the VASS certificate, the mod plate photograph and the signatory's report.
