Vehicle noise in Westchester is governed by NY Vehicle and Traffic Law 386, which sets decibel limits for passenger cars at 76 dBA at 50 feet. Modified exhaust systems and loud motorcycles are enforced by county police on parkways and Thruway. Yonkers and White Plains run targeted enforcement.
NY VTL 375(31) prohibits muffler bypass, cutouts, and amplifiers. Westchester County Police enforce on the Bronx River, Hutchinson River, Saw Mill, and Sprain Brook parkways. The SLEEP Act (S.784B, effective 2022) raised fines for illegally modified mufflers to up to 1,000 dollars. Stationary vehicle idling is limited to 3 minutes statewide under NY DEC 6 NYCRR Part 217.
Illegal muffler: up to 1,000 dollars under SLEEP Act. Excessive idling: 375 to 18,000 dollars under DEC regulations for commercial trucks.
