state government to enact idling restrictions for big trucks and other diesel
The proposed restrictions would limit idling to five minutes
per hour, except when the temperature falls below 40 degrees or above 80. The
restrictions do not apply if the truck is using anti-idling technology, such as
an auxiliary power unit.
An article in the Harrisburg Patriot-News referred to
the five-minute limit as "a sufficient time to heat or cool an occupied truck
All idling - regardless of temperature - would be restricted
to five minutes after 2010. Again, anti-idling technologies would be excluded.
