California Roadside Saliva (Oral Fluid) DUI Testing Law
How California treats oral fluid (saliva) testing in DUI enforcement — the statute, its current status, and what that means for agencies running roadside drug screening.
Status: Authorized · Law Exists, Deployment Varies
Statute and status in California
Statute / authority: Vehicle Code § 23612 (bodily fluids)
Some agencies use oral fluid under broad statutory authority. No formal statewide oral fluid DUI program.
What this means for agencies in California
California's statute is broad enough to permit oral fluid, but there is no statewide program, so adoption sits with individual agencies and prosecutors. Agencies piloting saliva screening here should pair every roadside result with a preserved specimen and documented chain of custody, so a case never rests on the screen alone.
