(1g)
(a) Except as provided in par. (b), no person may remove, alter or obliterate or intentionally make it impossible to read, as required under sub. (2), an identification number. This subsection does not apply to the obliteration of an identification number which occurs in the process of crushing a vehicle or vehicle part for scrap.

(2) Except as provided in this subsection, an identification number assigned by the department to a vehicle shall be permanently affixed to a location on the vehicle specified by the department that is readily visible when observed from outside the vehicle. Identification numbers assigned for cycles shall be stamped on the left side, near the top of the engine casting just below the cylinder barrel. Such stamping or affixing shall be done under the supervision of a dealer, distributor or manufacturer registered under s. 341.51 or under the supervision of a peace officer. The person supervising the stamping or affixing shall make a report thereof to the department. The department shall establish forms to be provided to vehicle owners specifying the location, for various types of vehicles, where identification numbers assigned by the department shall be stamped or affixed.

(4)
(a) If a law enforcement agency finds a vehicle or part of a vehicle on which the identification number has been removed, altered or obliterated or made impossible to read, the law enforcement agency may seize the vehicle or part of a vehicle. If the identification number cannot be identified, the seized vehicle or vehicle part is presumed to be contraband. Except as provided in par. (d), if the identification number can be identified, the agency may return the vehicle to the owner. Except as provided in par. (b), the district attorney shall institute forfeiture proceedings under s. 973.076 regarding any vehicle or vehicle part that is seized under this paragraph and not returned to the owner.
(b) If the district attorney brings a criminal action arising out of the seizure under par. (a), the district attorney shall not institute forfeiture proceedings under s. 973.076 before there is a final determination in the criminal action.
(c) Paragraph (a) does not apply to the obliteration of an identification number that occurs in the process of crushing a vehicle or vehicle part for scrap.
(d) If the identification number of a motorcycle or part of a motorcycle seized under par. (a) can be identified and if no forfeiture proceeding is commenced under s. 973.076 within 30 days after the seizure of the property, the custodian of the seized property shall immediately return the seized property to the owner named in the certificate of title or registration. If a motorcycle or part of a motorcycle is not returned to the owner named in the certificate of title or registration as required in this paragraph, and if the owner of the property commences a replevin action to recover possession of the property, and if the judge finds that the custodian of the property unreasonably retained the property after 30 days after the seizure, the court shall award the owner the costs and reasonable attorney fees incurred in the replevin action.
