noise control requirements (40 CFR 205) and local noise level requirements.
Operation on Public Lands in the U.S.A.
Your POLARIS vehicle has a spark arrester that was tested and qualified to be in accordance with the USFS
standard 5100-1c. Federal law requires that this spark arrester be installed and functional when the vehicle is
operated on public lands.
Operation of off-road vehicles on public lands in the U.S.A. is regulated by 43 CFR 420. Violations are subject to
monetary penalties. Federal regulations can be viewed online at www.gpoaccess.gov/ecfr/.
