What it does
Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.
This bill modifies numerous provisions relating to operating a motor vehicle while intoxicated (OWI) to reflect holdings of the supreme courts of the United States and Wisconsin.
Under current law, no person may operate a motor vehicle while under the influence of an intoxicant, with a detectable amount of a restricted controlled substance in their blood, or with a prohibited alcohol concentration. Under current law, any person who operates a motor vehicle on public highways in this state is deemed to have given consent to one or more tests of their breath, blood, or urine, for the purpose of determining the presence or quantity in their blood or breath, of alcohol, controlled substances, controlled substance analogs, or other drugs (commonly known as “implied consent”).

Under current law, if a person is involved in a motor vehicle accident that causes substantial bodily harm, great bodily harm, or death and a law enforcement officer detects the presence of alcohol, controlled substances, controlled substance analogs, or other drugs, the person may be requested to provide one or more samples of their blood, breath, or urine for testing. If the person refuses, their operating privilege must be revoked. In State v. Blackman, 2017 WI 77, 377 Wis. 2d 339, 898 N.W.2d 774, the Wisconsin Supreme Court held that probable cause of an OWI violation is a prerequisite to revocation of an operating license for a refusal. The bill modifies provisions consistent with this holding.
Under current law, a person who would be requested to provide samples for testing but who is unconscious or otherwise not capable of withdrawing consent is presumed not to have withdrawn consent and one or more samples may be collected (commonly known as the “incapacitated driver provision”). In State v. Prado , 2021 WI 64, 397 Wis. 2d 719, 960 N.W.2d 869, the Wisconsin Supreme Court held that the incapacitated driver provision is unconstitutional. The bill repeals provisions consistent with this holding.
Under current law, there are separate but analogous implied consent and incapacitated driver provisions applicable to all-terrain vehicles (ATVs), utility terrain vehicles (UTVs), boats, and snowmobiles. Pursuant to Prado, these provisions are repealed. In addition, if a person refuses to submit to a test of their breath, blood, or urine related to their operation of an ATV, UTV, boat, or snowmobile, they are subject to a criminal penalty. In Birchfield v. North Dakota , 579 U.S. 438, 136 S. Ct. 2160, the U.S. Supreme Court held that it is unconstitutional to criminalize a refusal to submit to a blood test incident to arrest for an OWI violation. The bill modifies relevant provisions to reflect this holding.
The bill also modifies the text of the “informing the accused” form, which a law enforcement officer must read to a person from whom a test sample is requested, in part to reflect changes made by the bill.
