Salt Lake City's Idle Free Ordinance
The Salt Lake City Council recently enacted an ordinance that prohibits unnecessary vehicle idling over two minutes within City limits.
The ordinance (12.58.010 et seq.) provides for some exceptions to the two minute idling limit, including if you are stopped at an official traffic control device or signal, if you are stopped at the direction of a police officer, to operate heaters or air conditioners when the temperature is below 32° or above 90° in certain circumstances, or to operate defrosters or other equipment to clear the windshield and windows.
Businesses with drive-through windows have additional responsibilities, but can be exempted from enforcement if they post city-approved idle free signs. Businesses can order signs from the City for $20.
