Rockland County, NY Environmental Rules: Vehicle Idling Restrictions (2026)

Chapter 377 of the Rockland County Code, adopted April 4, 2007 by Local Law No. 4-2007, prohibits any person from causing or permitting a motor vehicle engine to idle for longer than three consecutive minutes when the vehicle is not in motion. The rule applies countywide, in every town and village of Rockland County, and exists to reinforce and supplement the Sanitary Code of Rockland County adopted by the County Board of Health under § 347 of the Public Health Law. 4 of the Sanitary Code.

The County is directed to post signs at locations that draw a substantial number of idling complaints, following the standards of the Manual on Uniform Traffic Control Devices, and where practicable those signs must state the maximum penalty. Critically, § 377-2(C) states that a missing sign is never a defense to a citation. Enforcement carries two tracks: a criminal violation under § 377-3(A), punishable on a first offense by a fine up to $250 or up to 15 days in jail, or both, rising to a fine up to $1,000 or up to 15 days in jail, or both, for a second or later offense; and a separate civil penalty of up to $1,000 per violation that the Commissioner of Health can pursue in any court of competent jurisdiction, with each day of continued idling counted as its own violation under § 377-3(B).
