Wis. Stat. § 940.10
A motorist was properly convicted under this section for running a red light at 50 m.p.h., even though the speed limit was 55 m.p.h. State v. Cooper, 117 Wis. 2d 30, 344 N.W.2d 194 (Ct. App. 1983). The definition of criminal negligence as applied to homicide by negligent operation of a vehicle is not unconstitutionally vague. State v. Barman, 183 Wis. 2d 180, 515 N.W.2d 493 (Ct. App. 1994). A corporation may be subject to criminal liability under this section. State v. Knutson, Inc. 196 Wis. 2d 86, 537 N.W.2d 420 (Ct. App. 1995), 93-1898. See also State v. Steenberg Homes, Inc. 223 Wis. 2d 511, 589 N.W.2d 668 (Ct. App. 1998), 98-0104. It is not a requirement for finding criminal negligence that the actor be specifically warned that his or her conduct may result in harm. State v. Johannes, 229 Wis. 2d 215, 598 N.W.2d 299 (Ct. App. 1999), 98-2239. The common law "year-and-a-day rule" that no homicide is committed unless the victim dies within a year and a day after the injury is inflicted is abrogated, with prospective application only. State v. Picotte, 2003 WI 42, 261 Wis. 2d 249, 661 N.W.2d 381, 01-3063.
