Arlington, VA – 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 which can be downloaded and carried in the glove box of a truck and the online compendium which provides links to individual regulations.

Additions to the listing include:

  • The State of Texas has adopted a new exemption which allows trucks with 2008 or newer engines certified to an idling emissions limit of 30 gram NOx per hour to idle. This exemption takes effect immediately.
  • A new 5-minute limit has been enacted in the State of Oregon which takes effect on January 1, 2012. Exemptions are provided which allow idling beyond this limit including for air conditioning or heating during a rest or sleep period when the outside temperature is less than 50 degrees or greater then 75 degrees any time during this period. Violations of this limit can result in fines up to $180.

ATRI 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 critical research relating to freight transportation’s essential role in maintaining a safe, secure and efficient transportation system.
