The American Transportation Research Institute (ATRI) has updated the listing of state and local idling regulations found on its website, www.atri-online.org. This updated listing is provided in two forms: a cab card that can be downloaded and carried in the glove box of a truck and the online compendium that provides links to individual regulations.

Three new idling regulations have been added to the listing.  These include:
•A new five-minute limit has been established in North Carolina. Idling beyond this limit is allowed for air-conditioning or heating sleeper berth compartments during federally mandated rest or sleep periods. This exemption expires May 1, 2011. Other exemptions include the idling of engines that meet the California low-nitrogen oxide (NOx) idling standard and when using an auxiliary power unit.
•A new 15-minute limit has been established in West Virginia.  An exemption is provided for sleeping or resting in a sleeper berth when temperatures are less than 40º F or greater than 75º F. This exemption expires May 1, 2012. An exemption is also provided for trucks displaying a CARB-issued low-NOx idle label.
•A new five-minute limit has been established in Detroit MI. An exemption is provided for vehicles that remain motionless for more than two hours when the temperature is less than 25º F.
