Tennessee Courts and Ignition Interlock Programs

Tennessee takes impaired driving seriously. After a DUI conviction, individuals face court proceedings, sentencing, and strict steps to regain their license. One common requirement is installing an ignition interlock device (IID), which prevents a vehicle from starting if alcohol is detected on the driver’s breath. Widely used across the state, IIDs help reduce repeat offenses and keep roads safer. Choosing the right state-approved IID provider can also make the court process smoother and less stressful. 

Steps After a DUI Arrest in Tennessee 

  1. Arrest – Law enforcement stops you, often after a traffic violation or suspicious driving, and performs sobriety or chemical tests. If you are impaired, you’re taken into custody. 
  1. Release or Bail – After booking, you may be released on bail, depending on risk factors such as prior DUIs, high BAC, reckless behavior. 
  1. Arraignment (Initial Hearing) – Usually 2–6 weeks post-arrest, you’ll appear in General Sessions Court to hear the charges and enter a plea. 
  1. Preliminary Hearings – Most misdemeanor DUIs remain in General Sessions Court, where defendants can accept plea deals, proceed to a preliminary hearing, or go to trial without a jury. 
  1. Criminal Court – If charged as a felony or indicted for serious circumstances, the case moves to Criminal Court and possibly a jury trial. 
  1. Sentencing or Trial – If convicted, sentencing may include jail, fines, DUI education, probation, community service, and IID installation. The judge may also order alcohol treatment or abstinence as part of probation terms. 
  1. License Suspension & IID Requirements – The court often suspends the license but may allow restricted driving with an IID. Drivers must install and use the IID for at least a year, comply with state reporting, and complete any education or treatment mandates. 

What Tennessee Law Requires 

Under Tennessee law, individuals convicted of a DUI, even for a first offense, may be required to install an ignition interlock device, depending on the circumstances of the case. The device must remain installed for a minimum of 365 consecutive days, and drivers are responsible for ensuring compliance with all court-ordered terms, including routine monitoring and calibration of the device. 

The court typically outlines specific conditions for each offender, and the Tennessee Department of Safety and Homeland Security oversees compliance. Offenders are expected to work with a state-approved ignition interlock provider, and failure to do so can delay the restoration of driving privileges. 

Working with the Courts: Why the Right Interlock Provider Matters 

One thing that can help streamline this process is choosing an ignition interlock provider that has experience working with the Tennessee court system and understands the state’s interlock compliance requirements. While there are several approved vendors in the state, some are more established than others when it comes to helping clients navigate the ins and outs of legal paperwork, DMV reporting, and timely maintenance.
