Community-Based Empirical Research
Diesel-powered vehicles in Pennsylvania are required by law (PA Act 124) to limit how long their engines may idle while the vehicle is not in motion. However, there is very limited funding for idling inspections and enforcement. At the request of the Clean Air Board (CAB) of Central Pennsylvania, Dickinson College Health Studies Seminar students visited two nearby Interstate 81 rest areas with large parking areas for tractor-trailer truck rigs. The students identified idling trucks and timed them for compliance with Act 124’s limit. The major finding was that more than 1/3 of the trucks observed violated Act 124 by idling in the rest area for more than 5 minutes.
