What this bill does
Plain-language analysis by the nonpartisan Legislative Reference Bureau
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 (OWI). If a law enforcement officer has probable cause to believe that a person has committed an OWI violation, the officer may request the person to provide a sample of his or her breath for a preliminary breath screening test. The result of this test is not admissible in any action or proceeding except to show probable cause for an arrest or to prove that additional chemical tests are required.
This bill provides that a law enforcement officer may request a sample of a person’s breath or oral fluids, or both, for a preliminary screening for OWI.
