How does SB 678 improve the drug-impaired driving law? SB 678 allows law enforcement to utilize roadside oral fluid screening to support the investigation of drug-impaired driving. The use of oral fluid screening will serve as a tool to help law enforcement determine which substance(s) are causing the impairment that is detected by the officer’s field observations and clues from Standardized Field Sobriety Testing. Combined, this information helps support probable cause for arrest and provides a law enforcement officer with evidence to seek a search warrant for a confirmation test and/or to contact a Drug Recognition Expert.

The problem of drug-impaired driving is not going away. From 2020-2024, according to the Wisconsin Department of Transportation, there were 353 drug-related traffic deaths in Wisconsin, including 65 in 2024. Also during this time period, there were 6,077 drug-related traffic injuries, including 1,053 in 2024. Enacting SB 678 and AB 681 will help reverse this deadly trend, save lives, and prevent injuries to Wisconsin residents.
