A bill (H.B. 2357) to exempt qualified collectible vehicles 15 years
old and older from the state's mandatory emissions inspection and
maintenance program has been signed into law by Arizona Governor Janet
Napolitano. Under a SEMA amendment, vehicles would have to be either
at least 15 years old or of unique design, limited production and an
object of curiosity. (The bill previously required vehicles to be both
15 years old or older and of unique design, limited production and an
object of curiosity.) Owners would have to maintain appropriate
collectible or classic automobile insurance and their vehicles would
be primarily used for car club activities, exhibitions, parades, etc.,
and only infrequently used for other purposes.

The new law must now be adopted by the U.S. EPA as part of Arizona's
state implementation plan for air quality.
