 "firstOffenseIidNote": "Under Tenn. Code Ann. § 55-10-425(b)(1), upon application by a person not otherwise prohibited from a restricted license, the court must order installation and use of a functioning ignition interlock for the 'ignition interlock usage period'; under § 55-10-425(b)(2)(B) the Department shall not reinstate the license of a person who did not apply for a restricted license until the person shows proof of a current interlock installation. The only exception is where the court makes specific findings on a Department form that none of the § 55-10-409(b)(2)(B) factors exist (BAC of 0.08% or higher or alcohol combined with drugs, a passenger under 18, an accident, or an implied-consent charge with a qualifying prior). TDOSHS lists 'Ignition interlock installation for 365-day minimum period' as a reinstatement requirement for every DUI conviction.",
 "sr22Note": "SR-22 (Tennessee uses the SR-22 form). The Tennessee Department of Safety and Homeland Security's Financial Responsibility Laws page lists 'SR-22 Insurance' and a $50 SR-22 fee among the DUI reinstatement requirements, and its Restricted License page requires SR-22 liability insurance for a DUI restricted license. The Department does not set a fixed number of years: both the Financial Responsibility Laws page and the Department's 'Do I need SR-22 Insurance?' article state that SR-22 insurance must be maintained for the length of the suspension or revocation period, after which it may be cancelled if not required on another suspension; sr22Years is therefore null. Cancelling the SR-22 before the requirement is complete can result in suspension for Failure to Maintain Future Proof of Financial Responsibility (T.C.A. 55-12-126).",
