Wisconsin Statutes Vehicles (Ch. 340 to 351) § 350.135. Interferences with uniform trail signs and standards prohibited

(1) No person may intentionally remove, damage, deface, move or obstruct any uniform snowmobile trail sign or standard or intentionally interfere with the effective operation of any uniform snowmobile trail sign or standards if the sign or standard is legally placed by the state, any municipality or any authorized individual. This subsection does not apply to an authorized individual who removes or moves any uniform snowmobile trail sign or standard from his or her own property.

(2) No person may possess any uniform snowmobile trail sign or standard of the type established by the department for the warning, instruction or information of the public, unless he or she obtained the uniform snowmobile trail sign or standard in a lawful manner. Possession of a uniform snowmobile trail sign or standard creates a rebuttable presumption of illegal possession.
