Ignition Interlock COVID-19 Update

As part of our continuing efforts to confront and limit the spread of COVID-19, the Tennessee Ignition Interlock Program is implementing the following protocols effective immediately:

  • All required monthly services are suspended until further notice; services will then resume on the originally scheduled day of the month. Your interlock provider will let you know if you need service before this goes into effect;
  • If service is required, you must provide all necessary breath samples;
  • You may still be required to have a final download service in order for a compliance check to be completed prior to program completion and device removal;
  • If you are unable to have the ignition interlock device removed upon compliance during this period, there shall be no monthly lease charge for the extended period.        

The Ignition Interlock Program advises the following:

  • We understand the importance of using hand sanitizer during this time. To reduce the chance of incurring a high BAC violation, use sanitizer outside of your vehicle and allow your hands to dry before giving a test;
  • Always provide a passing retest within 10 minutes for any fails;
  • Services will be provided at the discretion of the manufacturer and the service center during this period.
