An implied-consent violation is not the same thing as a DUI conviction. Tennessee treats refusal as a separate driver-license matter. A person can be acquitted of DUI yet still face an implied-consent suspension, or the refusal issue can be defeated even while the DUI charge continues. Understanding that separation is important because the evidentiary and procedural questions are different.
The refusal case usually turns on what the officer knew, what test was requested, whether the driver was properly advised of the consequences, and whether the person actually refused. Kevin Kennedy represents drivers facing both DUI and implied-consent allegations in Nashville and Middle Tennessee and evaluates the refusal procedure independently from the criminal DUI evidence.
What Tennessee’s Implied Consent Law Says
Under Tenn. Code Ann. § 55-10-406, a person who operates a motor vehicle in Tennessee is deemed to have given implied consent to breath tests, blood tests, or both for determining alcohol or drug content when the statutory conditions are satisfied.
The officer must have probable cause to believe the driver committed DUI or one of the listed intoxication-related vehicular offenses before requesting the test under the statute.
The Officer Must Give the Required Warning
Before administering a requested breath or blood test under the implied-consent procedure, the officer must advise the driver that refusal will result in a court-ordered driver’s license suspension and may have ignition-interlock consequences depending on the person’s history and DUI outcome.
If the officer fails to provide the required warning, § 55-10-406 limits the court’s authority to impose the refusal-based suspension.
Refusal Is Not a Criminal Offense
Tenn. Code Ann. § 55-10-407 expressly states that a person found to have violated the implied-consent law is not considered to have committed a criminal offense. The principal consequence is license suspension. That makes implied consent different from a misdemeanor conviction even though the refusal may be handled in the same court proceeding as the DUI arrest.
How Long Is the License Suspension?
For a driver without a qualifying prior conviction, the refusal suspension is generally one year. A driver with a qualifying prior conviction generally faces two years.
The suspension is also two years when the refusal occurs in a collision in which one or more people suffer serious bodily injury, and five years when the collision results in a death.
The Refusal Charge Must Be Separate
Section 55-10-407 requires a refusal allegation to be charged by a separate warrant or citation from any DUI charge arising from the same incident.
The court can determine the implied-consent issue at the same time it resolves the DUI or at the procedural stage specified in § 55-10-406. The separate charging requirement reinforces that refusal and DUI are distinct legal questions.
What Counts as a Refusal?
A refusal may be explicit, but disputes can arise when the driver’s answer was unclear, the person requested more information, medical circumstances interfered, or the driver initially agreed and later withdrew consent. Body-worn camera footage can be decisive because it shows the exact request, warning, response, and whether the driver had a meaningful opportunity to comply.
A Warrant Can Override the Refusal
Refusing a test does not necessarily prevent law enforcement from obtaining chemical evidence. Tennessee law permits blood testing under a search warrant and in qualifying exigent circumstances.
A driver can therefore face an implied-consent allegation and still have a blood sample taken pursuant to judicial authorization. The refusal issue and the admissibility of the blood evidence must then be evaluated separately.
Mandatory Testing Situations Still Require Constitutional Compliance
Section 55-10-406 requires testing in specified situations involving injury or death collisions, child passengers, or qualifying prior convictions, but the statute also addresses the warrant or exigent-circumstance requirements for compelled blood draws.
The defense should review the warrant affidavit, timing, probable cause, and whether the statutory and constitutional requirements were followed.
When a Suspension Can Be Revisited
Section 55-10-407 allows reinstatement in a narrow circumstance when the license was suspended for implied consent before disposition of the companion case and the underlying arrest is dismissed upon a finding that the officer lacked sufficient cause for the initial stop.
That provision makes suppression and stop-legality issues potentially relevant to the license consequence as well as to the DUI prosecution.
How Kevin Kennedy Defends Implied Consent Cases
Kevin reviews the stop, probable cause, officer warnings, standardized waiver, body-worn camera footage, the exact request for testing, the driver’s response, and any warrant later obtained.
The defense may challenge whether there was a valid refusal, whether the statutory warning was given, whether probable cause existed, or whether the officer followed the required procedure.
