Pennsylvania’s Diesel-Powered Motor Vehicle Idling Act
Pennsylvania Department of Environmental Protection
In accordance with PA Act 124, which states that diesel vehicles may not stand in idle longer than 5 minutes if they are not a bus or school vehicle, if you have a loading or drop-off area located near building entrances or HVAC intakes, post signage to remind vehicles to turn off their engines rather than idle at these locations. This will minimize the influx of carbon monoxide and other air pollutants directly into your facility from the outdoors.
