Relating to: the use of oral fluids for preliminary screening of a person suspected of operating a motor vehicle while intoxicated.

SB 678 allows law enforcement officers to request a sample of a person's oral fluids (or breath) as a preliminary screening tool when they suspect someone is driving under the influence of alcohol or drugs. This applies before an arrest for DUI violations, and the test results can only be used to decide whether to arrest the driver or request a formal chemical test later. The bill specifies that refusal to take this oral fluid screening does not trigger penalties under other statutes, and the results cannot be used as evidence in court except to establish probable cause for an arrest. It directly affects drivers suspected of DUI and officers conducting roadside screenings.
