Texas Roadside Saliva (Oral Fluid) DUI Testing Law
How Texas treats oral fluid (saliva) testing in DUI enforcement — the statute, its current status, and what that means for agencies running roadside drug screening.
Status: Limited / Voluntary Only
Statute and status in Texas
Statute / authority: Tex. Transp. Code § 724.012 (blood/breath)
Implied consent covers blood and breath. 2025/26 law updates focus on enhanced blood warrant authority, not oral fluid.
What this means for agencies in Texas
Texas currently limits chemical testing for drugs to blood, breath or urine, or permits saliva only in a narrow case. Roadside saliva screening can still support probable cause and officer decision-making where department policy allows, but it is not an evidentiary specimen under current law. Several states moved from this position to authorized in the past two years — watch the legislature.
