Tennessee DUI & License Suspension — What Happens

License consequences are often the most immediately disruptive part of a DUI case in Tennessee. The administrative suspension is a separate proceeding from the criminal case and can result in loss of driving privileges even if the criminal charges are eventually reduced or dismissed §55-10-406.

• First-offense (failed test): 1 year (18 months effective January 1, 2026). Note: Tennessee does not have a separate DMV-administered ALS process — the implied consent violation is handled by the same court as the criminal DUI.
• First-offense (refusal): 1-year license revocation (18 months effective January 1, 2026)

Tennessee does offer a form of restricted or limited driving privileges during or after the administrative suspension. Restricted license available under §55-10-409 with IID and/or geographic restrictions.

Losing the administrative hearing does not prove guilt in the criminal case. However, the facts overlap significantly, and the administrative hearing can sometimes reveal evidence or testimony that is useful in the criminal defense.
