AI Summary
This bill expands the types of preliminary screening tests that law enforcement officers can use when investigating suspected operating while intoxicated (OWI) offenses, specifically allowing for the use of oral fluid samples in addition to breath samples. A preliminary screening test is a quick test used by officers to determine if there is probable cause to believe a person is under the influence of alcohol or drugs, which can then lead to an arrest or a more formal chemical test. The bill amends various statutes related to operating all-terrain vehicles, off-highway motorcycles, boats, and snowmobiles, as well as general OWI laws, to include oral fluid samples as an option for these initial screenings. It also clarifies that any oral fluid sample collected can only be used for the preliminary screening test and must be destroyed or returned to the person afterward, preventing its use for other purposes.
