Smoky Vehicle Reporting Program

An initiative to address public concerns about vehicle emissions.
Last updated:

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.

About the program

The Smoky Vehicle Reporting Program is a joint initiative of the Department of Water and Environmental Regulation and Department of Transport.

It aims to:

  • identify vehicles that are at risk of breaching vehicle emission legislation
  • engage with vehicle owners to undertake any necessary vehicle maintenance.

It is also a key strategy of the National Environment Protection (Diesel Vehicle Emissions) Measure 2001 and the Perth Air Quality Management Plan. 

Read more about the Smoky Vehicle Reporting Program in the annual reports below.

What is a smoky vehicle?

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.
