Louisiana Roadside Saliva (Oral Fluid) DUI Testing Law
How Louisiana 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 Louisiana
Statute / authority: La. R.S. 32:661 — "blood, breath, urine, or other bodily substance"
RS 32:661 explicitly authorizes testing of "blood, breath, urine, or other bodily substance" under implied consent. Saliva testing for controlled substances is permitted. Refusal = immediate license seizure + 1-year suspension.
What this means for agencies in Louisiana
Louisiana'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.
