TN HB1204

First-offense DUI suspects who refuse a blood test face an extended license revocation period of 1 year and 6 months, compared to 1 year for those who comply with testing

Refusing blood, breath, or both tests after arrest and warning constitutes a violation even if blood is later obtained through a search warrant, court order, or exigent circumstances

Oral fluid tests are authorized for DUI detection with operator consent, search warrant, incident to lawful arrest, or under exigent circumstances, and results are admissible as evidence

Vehicular assault penalties increase from 3 years to 6 years and from 5 years to 8 years under Section 39-13-106(c), effective January 1, 2026

Oral fluid testing and refusal provisions take effect immediately upon becoming law; license revocation and assault penalty changes take effect January 1, 2026
