TRESPASS – Adds to existing law to establish provisions regarding a violation of landowner rules for permissible use.

S 1086 (Idaho Code §18-7045) clarifies that violating posted landowner restrictions for recreational use on public or private land constitutes trespass. It requires landowners or government entities managing land to post clear signs stating "use restrictions apply" along with a contact website or phone number. This law directly affects recreational users (like hikers, campers, or off-roaders) who ignore these posted rules. The bill makes such violations punishable under existing trespass penalties (Idaho Code §18-7008(3)), effective July 1, 2025.
