The bill requires trappers to post notice signs in specific locations on public lands administered by the Department of Fish, Wildlife, and Parks. Trappers must place these signs at trailheads where traps or snares are located within 1,000 feet of the trailhead or within 100 feet of any point on a public trail. If no trailhead exists, the sign must be posted at the point of access to the public trail if traps or snares are within 100 feet. The notice sign must meet certain requirements, including size, durability, and content, and must inform the public about the presence of traps or snares, as well as the legal implications of disturbing them.

Additionally, the bill outlines the responsibilities of trappers regarding the maintenance of these signs, stating that they must replace any illegible or missing signs within 24 hours and can only remove the signs after their traps and snares have been taken down. The bill also provides definitions for "public trail" and "trailhead" to clarify the terms used in the legislation. This new section is intended to be codified as part of Title 87, chapter 2, part 6 of the Montana Code.
