Operation on Public Lands in the U.S.A.
Your POLARIS vehicle has a spark arrestor that was tested and qualified to be in accordance with the USFS standard 5100-1d. Federal law requires that this spark arrestor 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.ecfr.gov.
