The QLD ICO app allows Approved Inspection Stations (AIS), that are approved to operate in Queensland, to access the Inspection Certificates Online (ICO) system. ICO allows AISs to create and issue inspection certificates (safety certificates and certificates of inspection) to customers electronically (via email or as a printed PDF) and, in some cases, automatically lodge them with the Queensland Department of Transport and Main Roads (TMR). In some cases, this removes the need for customers to attend a TMR Customer Service Centre to perform some transactions as the required inspection certificate has already been provided to TMR. This includes some registration transfer and registration renewal transactions that are available online.

AISs are able to manage their vehicle inspection records through ICO and access relevant information and documentation through the ICO Library.

ICO also allows AISs to record vehicle defect inspections and lodge them electronically with TMR. This removes the need for customers to present the signed defect notice clearance to TMR before being issued with a certificate of inspection to meet their programmed vehicle inspection requirements.
