(RENO, Nev.) – The Department of Motor Vehicles and Public Safety (DMV&PS) challenges drivers to participate in National Clean Air Month, May 2001, by testing their knowledge of vehicle related air pollution and answering the Smog Smart Trivia questions.

 To test your smog smart IQ, see how many question you answer correctly:


1. What part of the vehicle do emissions come from?

The tail pipe and the hood.

2. What three pollutants do vehicles emit?

·      Hydrocarbons: react with nitrogen oxides in the presence of sunlight and hot temperatures to form ground-level ozone.

·      Nitrogen oxide: contributes to the formation of ozone and acid rain. 

·      Carbon monoxide: reduces flow of oxygen in bloodstream and can impair mental alertness and vision.  Studies have reported that in urban areas, as much as 90 percent of carbon monoxide in the air is a result of motor vehicles.

3. What are three things drivers can do to reduce visible vehicle emissions?

·      Keep vehicles in good running condition: poorly maintained vehicles emit as much as 10 times the emissions as well-maintained vehicles.

·      Travel at moderate steady speeds and reduce idling time:  idling more than half a minute burns more gas that it takes to restart the engine.

·      Use clean fuels when available: including reformulated gasoline, oxygenated gasoline and alternative fuels.

4. What is the number to report a smoking vehicle?


5.  How many colors of smoke do vehicles emit?

Four: Blue, gray, black and white.

 The smoking vehicle program started in 1996, resulting in more than 32,000 calls over the last five years to the DMV.  The program has helped to get more than 5,000 smoking vehicles cleaned up resulting in cleaner air for the region.
