Laws & Ordinances

Many local and state governments have adopted laws and ordinances that limit vehicle idling to combat increasing air pollution and greenhouse gas emissions. Each law and ordinance varies in who it targets, the basic overall structure, and the penalties associated with not complying, however, the overall objective of each law and ordinance remains the same – to protect air quality by reducing emissions created by unnecessary vehicle idling.
