Idle Free Ordinance

Poor air quality is a significant public health concern for those who live in the Salt Lake Valley. Due to our geography, climate and growing population, air pollution is a persistent problem that contributes to respiratory issues such as asthma, emphysema, lung cancer, and impacts our overall quality of life.
 
Vehicle exhaust makes up over 50% of the air pollution in Utah, and unnecessary idling of cars and buses contribute a significant amount of emissions released into the air each day.
 
In the fall of 2011, the Salt Lake City Council unanimously approved a proposal from Mayor Ralph Becker to create the City's first Idle Free Ordinance. The ordinance prohibits unnecessary vehicle idling over two minutes within city limits.
