The 30-Second Version
If you refuse a blood test in a Tennessee DUI stop on or after January 1, 2026, you lose your license for 18 months. That is six months longer than the old rule, even for a first-time driver with a clean record.
The law also adds a roadside saliva test to the implied-consent menu, lets officers assist in "reasonable force" blood draws, and closes the warrant loophole that used to let refusal charges get dismissed when police obtained blood by warrant anyway.
If you drive in Murfreesboro, Smyrna, or anywhere in Rutherford County, this one touches you.
What the New Law Actually Says
HB1204/SB1400, now law in Tennessee, amends the implied-consent statute at T.C.A. § 55-10-406. The headline change: a first-time refusal of a blood test now triggers an 18-month driver license suspension instead of the old 12 months.
Three more changes matter:
- Oral fluid (saliva) testing is now an admissible chemical test under implied consent.
- Law enforcement can now assist a qualified practitioner in using reasonable force to obtain a blood sample.
- An implied consent violation can now be charged even if police later obtain blood through a search warrant. That old escape hatch is closed.
"A person can now lose their license for a year and a half simply for refusing to submit to a blood draw, even if he or she has never been in trouble with the law before."

Why Refusing Used to Be the "Safer" Move
For years, defense attorneys often advised drivers to refuse a blood test. The logic was simple: the refusal cost you a one-year license suspension, but so did a DUI conviction. Refusing could block the State from getting a per se BAC reading over 0.08, which sometimes meant the DUI itself got reduced or dismissed.
Starting January 1, 2026, that calculus flips. You can now lose your license for 18 months on the refusal alone, even if the DUI gets dropped. And if police get a warrant for your blood anyway, you face both an implied consent violation and the DUI.
How This Plays Out in Rutherford County
A Murfreesboro DUI stop in 2026 looks different than it did a year ago. An officer with suspicion of impairment now has three tools available without a warrant in many cases: breath, blood draw (with reasonable force if needed), and a saliva swab.
Having worked traffic stops as a police officer before becoming a prosecutor and then a defense attorney, I can tell you where these cases get won or lost: the stop itself, the officer's probable cause for the test, and whether the driver was properly advised of the consequences of refusal. Those challenges are still available under the new law.
What This Means for You
- If you are pulled over on suspicion of DUI in Tennessee after January 1, 2026, refusal is no longer an obvious "safer" choice.
- The advisement the officer gives you at the roadside must accurately reflect the new 18-month suspension. Errors can still invalidate a refusal.
- If you are arrested, do not answer questions beyond identifying yourself. Ask for a lawyer.
- If you refused and are facing an implied consent hearing, the administrative proceeding is separate from your DUI criminal case. Both need defense.
What to Do Next
If you are facing a DUI or implied consent charge anywhere in Rutherford, Williamson, Wilson, Rhea, Warren, Bledsoe, or Sequatchie County, time matters. The administrative license suspension window is short, and evidence preservation has to start immediately.
