Arizona idling law: the 5 minutes (Phoenix area) rule
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.
