Pennsylvania Truck Idling Law
Pennsylvania bars diesel trucks over 10,000 pounds in commerce from idling more than 5 minutes in any 60-minute period (Act 124 of 2008, 35 P.S. Ch. 23B). There is no cold-weather sleeper-berth break anymore; that exemption expired in 2010, so plan on an APU, which can run without limit. The fine is $150 to $300. Philadelphia is stricter at 2 minutes.
