Vermont state law: prohibited idling of motor vehicles
In May 2013, Vermont Gov. Peter Shumlin signed into law S.150 - An act relating to miscellaneous amendments to laws related to motor vehicles, a bill passed by the legislature, which includes the provision: prohibited idling of motor vehicles. The law became effective May 5, 2014; it limits the idling of all motor vehicles while parked to five minutes in any 60 minute period, with exceptions. This is the law: 23 V.S.A. § 1110. Prohibited idling of motor vehicles. As enacted into law: Act 57 (Section 28, pages 30-32).
Vermont school bus idling rule
In 2007, the Vermont legislature, learning of the negative impact idling school buses had on students, taxpayers and Vermont's environment, passed Act 48: an act related to the idling of school buses on school grounds. This became know as the Vermont School Bus Idling Rule, enacted into law in 2008. There is also an option in the law for school boards in each district to adopt idling policies for motor vehicles other than school buses (employees, students, parents, delivery, etc.) when present on school grounds.

Vermont unattended motor vehicle law
23 V.S.A. § 1111. Unattended motor vehicle prohibits allowing a vehicle's engine to run while unattended in public. Enacted in 1973 to discourage vehicle theft but can also be applied toward idling enforcement. Many Vermonters are not aware that if leaving a vehicle unattended in public (such as going into a convenience store), the engine must be shut off. Police call the practice of leaving the car running while unattended, especially in cold weather, "puffing" - puffs of hot exhaust into cold air that acts like a beacon to would-be car thieves.
Vermont "smoky truck" law
23 V.S.A. § 1222a. Emissions of diesel-powered commercial vehicles: Observe a commercial truck spewing black soot from its exhaust? It may be stopped and an inspection performed if it appears vehicle exhaust exceeds standard.

Idling laws in other states
As of 2014, a total of 19 U.S. states have statewide idling laws. Additional states have jurisdictional idling laws. These laws cover at least trucks over a certain weight, with seven covering all vehicles. Maximum idling time limits vary from three to 15 minutes (usually in any 60-minute period). All of these laws have listings of exceptions or exemptions related to safety, operation, or comfort.
The American Transportation Research Institute (ATRI), a well-known leader in transportation-related research, compiles an updated list of commercial vehicle idling regulations (according to weight and class), as well as those states with all motor vehicle idling laws. In addition, Clean Cities, an initiative of the U.S. Department of Energy (DOE), has launched IdleBase, a comprehensive database of known idling laws related to the idling of all classes of on-road vehicles. The database, which covers vehicles ranging from motorcycles and passenger cars to school buses and heavy-duty trucks, is available here for download.
