Idle Reduction Requirement

A motor vehicle may not idle for more than five consecutive minutes. This regulation does not apply to: 1) vehicles being serviced, provided that operation of the engine is essential to the repair; 2) vehicles delivering or accepting goods or merchandise for which engine assisted power is necessary and substitute alternate power cannot be made available; or 3) vehicles requiring auxiliary power for an associate power need other than movement that cannot be substituted by an alternate power source provided that such operation does not cause or contribute to air pollution. Violators are subject to fines. Local boards of health, local police, and state and federal officials may enforce the state anti-idling law.
