Status: Verified · Enacted + Active Deployment
Statute and status in Montana
Statute / authority: MCA § 61-8-1016 — Oral fluid explicitly named
MCA 61-8-1016 explicitly lists "oral fluid" as an authorized test specimen alongside blood and breath in the implied consent statute. Refusal triggers license suspension.
What this means for agencies in Montana
Montana has written oral fluid into its DUI framework and agencies are deploying it. Roadside saliva screening with a preserved specimen for laboratory confirmation is the workflow OraPlex™ was built for: an observed collection in about a minute, a preliminary result at the roadside, and a split sample the laboratory can quantify.
