      (am)    A court shall order one or more of the following:

         1.    That the person’s operating privilege for the operation of “Class D” vehicles be restricted to operating vehicles that are equipped with an ignition interlock device and, except as provided in sub. (1m), shall order that each motor vehicle for which the person’s name appears on the vehicle’s certificate of title or registration be equipped with an ignition interlock device.

         2.    That the person participate in a program described in s. 165.957 or that meets the definition of a 24-7 sobriety program under 23 U.S. Code § 405 (d) (7) (A) and regulations adopted thereunder. If the court enters an order under this subdivision, when the person completes or otherwise does not participate in the program, the court shall order that the person’s operating privilege for the operation of “Class D” vehicles be restricted to operating vehicles that are equipped with an ignition interlock device, shall specify the duration of the order, shall, except as provided in sub. (1m), order that each motor vehicle for which the person’s name appears on the vehicle’s certificate of title or registration be equipped with an ignition interlock device, and shall notify the department of such order.

   (1m)   

      (a)    If equipping each motor vehicle with an ignition interlock device under sub. (1g) would cause an undue financial hardship, the court may order that one or more vehicles described in sub. (1g) not be equipped with an ignition interlock device.

      (b)    An order under sub. (1g) does not apply to a vehicle for which the department has not approved an ignition interlock device capable of being installed on the vehicle.

   (2m)   

      (a)    If the court enters an order under sub. (1g) (am) 1., the restriction of the person’s operating privilege under the order under sub. (1g) (am) 1. shall begin on the date the order under sub. (1g) (am) 1. is issued and extend for a period of not less than one year after the date the department issues any license granted under this chapter nor more than the maximum operating privilege revocation period permitted for the refusal or violation after the date the department issues any license granted under this chapter except that if the maximum operating privilege revocation period is less than one year, the restriction of the person’s operating privilege under sub. (1g) (am) 1. shall extend for a period of one year after the department issues any license granted under this chapter. If the court enters an order under sub. (1g) (am) 1., the court may specify the date by which an ignition interlock device under sub. (1g) (am) 1. shall be installed.

      (b)    If the court enters an order under sub. (1g) (am) 2. that does not restrict a person’s operating privilege for the operation of “Class D” vehicles to operating vehicles that are equipped with an ignition interlock device while he or she participates in a program, the court shall order that the time period during which the person participates in a program, combined with the time period for which the person’s operating privilege is restricted under sub. (1g) (am) 2. equals not less than one year nor more than the maximum operating privilege revocation period permitted for the refusal or violation, except that if the maximum operating privilege revocation period is less than one year, the time period shall equal one year. The time period for which the person’s operating privilege is restricted under sub. (1g) (am) 2. begins on the date the department issues any license granted under this chapter. The court may order the person to install an ignition interlock device under sub. (1g) (am) 2. immediately after his or her participation in the program ends or while the person completes the program and for the additional period of time required under this paragraph, and shall notify the department of the date the person’s participation ended and the duration of the order restricting the operating privilege. A person subject to an order requiring installation of an ignition interlock device shall, within 2 weeks after the date on which installation of the ignition interlock device is required under the order, submit proof to the sheriff in his or her county of residence that an ignition interlock device has been installed in each motor vehicle to which the order applies.

   (3)   

      (a)    Except as provided in par. (b), if the court enters an order under sub. (1g), the person shall be liable for the reasonable cost of equipping and maintaining any ignition interlock device installed on his or her motor vehicle.

      (b)    If the court finds that the person who is subject to an order under sub. (1g) has a household income that is at or below 150 percent of the nonfarm federal poverty line for the continental United States, as defined in 42 U.S. Code § 9902 (2), the court shall limit the person’s liability under par. (a) to one-half of the cost of equipping each motor vehicle with an ignition interlock device and one-half of the cost per day per vehicle of maintaining the ignition interlock device.

   (4)   A person to whom an order under sub. (1g) applies violates that order if he or she fails to have an ignition interlock device installed as ordered, removes or disconnects an ignition interlock device, requests or permits another to blow into an ignition interlock device or to start a motor vehicle equipped with an ignition interlock device for the purpose of providing the person an operable motor vehicle without the necessity of first submitting a sample of his or her breath to analysis by the ignition interlock device, or otherwise tampers with or circumvents the operation of the ignition interlock device.

   (5)   If the court enters an order under sub. (1g), the court shall impose and the person shall pay to the clerk of court an ignition interlock surcharge of $50. The clerk of court shall transmit the amount to the county treasurer.
