Vehicle Emissions

The State of Alaska has a potential for wintertime health problems with Carbon Monoxide (CO) in the Anchorage area.

Automobiles and trucks are the source of most of the carbon monoxide emissions in Alaska. For this reason nearly all vehicles that are operated in the Municipality of Anchorage are required to pass a vehicle emissions test every two years. Exceptions to this requirement include new and very old vehicles, diesel engine vehicles, vehicles that are very large (with an unladen weight of 12,000 pounds or more), and motorcycles, snow machines, etc.

Vehicles used regularly to commute into the Municipality of Anchorage for work or school are also required to pass an emissions test every two years.

Starting January 1, 2010 new model vehicles will be exempt for the first six years. For example, in 2012, 2006 model year vehicles will be required to be tested for the first time.
