Arizona idling law: the 5 minutes (Phoenix area) rule
By Mario Bailey
Arizona legislates through its counties: ARS §11-876 requires counties containing “Area A” (the Phoenix metro region) to adopt and enforce ordinances limiting heavy-duty diesel vehicles over 14,000 lbs to 5 consecutive minutes of idling.
Exceptions that actually matter
- Police, fire, and emergency vehicles
- Traffic delays and drivers sleeping in the vehicle
- Equipment operations such as cargo refrigeration
Penalties
The statute sets a $100 civil penalty for a driver’s first violation of a county ordinance adopted under it; counties handle enforcement.
Who enforces it, and how to report
County ordinances mandated by state law in the Phoenix-area Area A; Maricopa County is the principal enforcer.
Report heavy-truck idling in the Phoenix area to county air-quality enforcement; there is no citizen reward.
Can you get paid for reporting in Arizona?
No. Arizona has no citizen reward, complaints are civic, not paid. The only major program that pays complainants is New York City's idling bounty, where citizens keep 25% of collected fines and our enforcement data shows what that produces: hundreds of thousands of cases and an estimated eight-figure sum paid to filers. If a paid program launches in Arizona, this page will say so.
