ARLINGTON, Va. — It’s not easy keeping track of idling regulations in the U.S. as States continue to bring in varying legislations.

The American Transportation Research Institute (ATRI) has got you covered and even has an up-to-date cab card available on their website.

The institute recently added new regulations to the list, as three States are currently developing idling regulations.

The website provides a listing of truck idling limits, exemptions and fines, as well as hyperlinks to more than 40 idling regulations throughout the U.S. The cab card, which is a free download, provides a quick reference guide to these limits and can be carried in the glove box of a truck.

The recent additions include:

The State of Florida recently adopted a 5-minute idling limit, which takes effect Dec. 15. This new limit includes various exemptions, including when sleeping or resting in a sleeper berth.

The State of Maine recently adopted a 5-minute limit, which took effect July 1. This new limit includes various exemptions, including for sleeper berth heating or cooling during rest or sleep periods.

The State of South Carolina recently adopted a 10-minute limit, which took effect July 1, with warning tickets being issued during the first year. This new limit includes various exemptions, including for sleeper berth heating or cooling during rest or sleep periods.

Idling regulations are being developed in the states of Georgia, North Carolina, and Pennsylvania.
