Vehicle emissions have adverse effects on human health and the environment. The air quality impacts of grossly polluting vehicles are potentially thousands of times that of newer or well-maintained vehicles in the same class.

The Smoky Vehicle Reporting Program (SVRP) is a key initiative of the Diesel NEPM and the Perth Air Quality Management Plan. The program is implemented with the support of the Department of Transport.

Smoky vehicles are defined by regulation 354 of the Road Traffic (Vehicles) Regulations 2014.  A vehicle must not emit visible emissions for a continuous period of more than 10 seconds.   The regulation applies to motor vehicles that are propelled by internal combustion engines that were built after 1930. However, it does not apply to emissions that are visible only because of heat or the condensation of water vapour.

A summary of the Smoky Vehicle Reporting Program, including program performance, is available in the latest annual report.
