be repaired; and

           * re-testing the repaired vehicle against the standardised test.

 Because they involve the actual repair of high polluting vehicles, vehicle test and repair programs offer a high degree of certainty that effective emissions reductions will be achieved.

3.       Program Outline

 To develop and implement an effective test and repair program a jurisdiction will need to:

           * specify appropriate target vehicle groups;

           * specify target pollutants;

           * implement a means of obliging or encouraging target vehicles to be tested and polluting vehicles to be repaired;

           * implement a testing regime with appropriate infrastructure that is effective in identifying high polluting vehicles with repairable faults;

           * educate and enlist the support of the vehicle repair industry;

           * educate and prepare the community through a communications program;

           * implement quality and fraud control mechanisms; and

           * monitor the effectiveness of the program.

           1. Target Vehicles

 Studies commissioned by the National Environment Protection Council have shown that vehicles less than five years old have few faults and therefore small benefits from emission repairs. For vehicles older than five years, there is a poor correlation between vehicle age and pollutant emissions and between vehicle kilometres travelled and pollutant emissions.  There is also a poor correlation between visible smoke or opacity and particle emissions.

 Jurisdictions should consider one or more of the following means of targeting vehicles from the Australian fleet for testing under a test and repair program:

           * All diesel vehicles over five years of age.

           * Random sampling or targeting particular vehicle class/es within the diesel fleet over 5 years of age (refer table below for emissions related fault profile of the fleet).

           * Random roadside testing.

3.2   Screening Testing

 Jurisdictions may wish to consider the use of screening testing to identify vehicles suspected of poor performance that need to be subjected to the full in-service emissions test.  Screening testing could involve the use of mobile briefcase and remote sensing systems or visual inspections
