Wisconsin Statutes Vehicles (Ch. 340 to 351) § 345.36. Not guilty plea; failure to appear

(a) Issue a warrant under ch. 968 and, if the defendant has posted bond for appearance at that date, the court may order the bond forfeited; or

(b) Deem the nonappearance a plea of no contest and enter judgment accordingly. If the defendant has posted bond for appearance at that date, the court may also order the bond forfeited. The court shall promptly mail a copy of the judgment to the defendant. The judgment shall allow not less than 20 days from the date thereof for payment of any forfeiture, plus costs, fees, and surcharges imposed under ch. 814. If the defendant moves to open the judgment within 20 days after the date set for trial, and shows to the satisfaction of the court that the failure to appear was due to mistake, inadvertence, surprise, or excusable neglect, the court shall open the judgment, reinstate the not guilty plea, and set a new trial date. The court may impose costs under s. 814.07. The court shall immediately notify the department to delete the record of conviction based upon the original judgment.
