 There are no periodic safety inspections in Queensland once a vehicle is registered, however, mobile road teams conduct random emissions inspections through a program called OVERT, and drivers may be summoned if their vehicles are not within legal guidelines or emits visible smoke.The majority of privately owned vehicles do not need to be inspected to be legally driven or have their interstate registration transferred to South Australia.Vehicles with certain types of modifications, specifically engine, chassis, wheel-base, seating capacity, brakes, steering, or suspension modifications require a certificate of roadworthiness prior to registration (or as a condition of continued registration).
