Arizona county implements idling law

| 7/1/2002

The Maricopa County Board of Supervisors is the first to give the nod to an ordinance that prohibits tractor-trailers from idling for more than five minutes. The ordinance is part of a plan created at the Governor's Brown Cloud Summit and the result of 2001 legislation.

In March 2000, Gov. Jane Dee Hull established the Brown Cloud Summit to investigate topics including ways to reduce pollution in the valley and how to put pollution-fighting measures into action. The final results of the study can be found on the Internet at

The anti-idling bill passed in the 2001 regular legislative session as a revision to legislation already in place. HB2538 amended the Arizona Constitution to allow all counties to adopt, implement and enforce idling laws on vehicles with a weight rating of more than 14,000 pounds. According to the schedule set by the governor, area A or parts of Maricopa, Pinal and Yavapai counties are the first to begin enforcing "Brown Cloud" policy.

The policy does include exemptions for emergency vehicles, certain types of situations such as traffic delays, or the need to sleep in the vehicle and certain types of equipment such as reefers.

Maricopa County and its towns lie between I-10 and I-8, south of Phoenix.

Under the new law, any county control officer or law enforcement officer may issue a citation. A first violation will be $100, subsequent citations $300. The county will begin ticketing on July 1.
