Ignition Interlock Device Laws

  • Tennessee ignition interlock device laws requires all DUI offenders to install an interlock device.
  • Offenders may be able to apply for limited driving privileges with the condition of interlock device installation, after completion of a minimum period of license revocation.
  • The length of that period depends on the offender’s conviction history, as does the overall length of the ignition interlock period.

License Suspension

Administrative Suspension

In Tennessee, any driver who is stopped for DUI is subject to an immediate license revocation if he or she registers a BAC of .08% or higher or refuses to take a field breathalyzer test.

Drivers with one or two DUI offenses may apply for restricted driving privileges during this administrative revocation period.

Those with three or more offenses are not eligible for restricted privileges.

The installation of an interlock device is a condition of these restricted privileges.

Judicial Suspension

DUI laws in Tennessee state that in addition to the administrative revocation, offenders are also subject to court-ordered license revocation upon conviction for DUI.

Courts will also impose jail sentences and fines on all offenders, even first-time offenders.
