Minneapolis, MN Environmental Rules: Vehicle Idling Restrictions (2026)

Minneapolis Code of Ordinances Chapter 58 bars idling a motor vehicle for more than three consecutive minutes in any one-hour period (§58.110), covering all gasoline and diesel vehicles not already regulated as commercial diesel trucks. Those larger diesel commercial vehicles fall under Article I instead, capped at five minutes idling per hour on the road and thirty minutes per hour while loading or unloading freight. Both articles exempt idling stuck in traffic, running defrosters or AC to prevent a safety emergency, and emergency vehicles on duty; the general article also allows fifteen minutes when the outside temperature is below zero or above ninety degrees Fahrenheit.
