The Diesel-Powered Motor Vehicle Idling Act (Act 124 of 2008) seeks to reduce unnecessary idling of the main propulsion engine in diesel-powered motor vehicles, including trucks and buses, by imposing time limits and sign requirements. Small busineses are often unaware of the sign requirements at their small business buildings and facilities. Unnecessary idling affects air quality and wastes fuel for truck owners and operators.
Act 124 states that "an owner or operator of a location where subject vehicles load or unload or a location that provides 15 or more parking spaces for subject vehicles shall erect and maintain a permanent sign." Thus, small business owners and operators should post at least one sign to alert drivers or delivery vehicles of the state idling requirements. Owners and operators should also realize that is part of the property owner's responsibility to prevent idling on their property.

Because Act 124 was enacted by the State, both state and local law enforcement officials were given authority to enforce the idling restrictions as well as Pennsylvania DEP personnel. DEP has created a fact sheet on Act 124 as well as a webpage on Diesel Idling and Act 124 Information.
