The American Transportation Research Institute continues to update and maintain a listing of state and local idling regulations on its website, www.atri-online.org. Two new idling regulations were added to the compendium in this latest update. The listing is provided in two forms, an online compendium which provides detailed information and Internet links to each of the 60 state and local regulations which have been identified; and a cab card which provides a consolidated listing of the state and local limits, The cab card is designed to be downloaded and carried in the glove box of a truck.

ATRI provides the compendium and cab card as a free service to help trucking companies and truck drivers comply with the myriad of state and local idling regulations.
