Idle Reduction Requirement

New Hampshire regulations help to minimize the impact from engine idling and reduce exposure to diesel exhaust emissions by establishing a limit on the amount of time that engines are permitted to idle. The limit is based on the outside temperature, as follows: Above 32 degrees Fahrenheit, 5 minute limit; between -10 degrees and 32 degrees Fahrenheit, 15 minute limit; below -10 degrees Fahrenheit, no limit. Certain vehicles are exempt from the regulation, including vehicles in traffic, emergency vehicles, vehicles providing power take-off for refrigeration or lift gate pumps, and vehicles supplying heat or air conditioning for passenger comfort during transportation. (Reference New Hampshire Department of Environmental Services, Administrative Rules Env-A 1101.05 and 1101.06)

Diesel Idle Reduction Initiative

In an effort to reduce air pollution in New Hampshire, the Department of Environmental Services educates diesel truck and bus drivers and owners about the environmental, financial, and health consequences of engine idling while the vehicle is not in motion through information, sample idling policies, and signage.
