ATRI Updates Online Idling Regulations Compendium

The American Transportation Research Institute (ATRI) has updated the listing of state and local idling regulations found on its website, The 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 5-minute limit has been established in the State of 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 on May 1, 2011. Other exemptions include the idling of engines that meet the California low-NOx idling standard and when using an auxiliary power unit.
  • A new 15-minute limit has been established in the State of West Virginia. An exemption is provided for sleeping or resting in a sleeper berth when temperatures are less than 40 degrees F or greater than 75 degrees F. This exemption expires on May 1, 2012. An exemption is also provided for trucks displaying a CARB-issued low-NOx idle label.
  • A new 5-minute limit has been established in the City of Detroit, Mich. An exemption is provided for vehicles which remain motionless for more than 2 hours when the temperature is less than 25 degrees F.

ATRI said it continues to monitor the development of idling regulations across the country and maintains the compendium and cab card as a free service to help trucking companies and truck drivers comply with the increasing number of state and local idling regulations.

ATRI is the trucking industry's 501(c)(3) not-for-profit research organization. It is engaged in research relating to freight transportation's essential role in maintaining a safe, secure, and efficient transportation system.
