TCA Codes and Information for Citations Relating to Ignition Interlock Law ViolationsMothers Against Drunk Driving is a strong supporter of All-Offender Ignition Interlock Laws because they save lives.  In fact, support of Ignition Interlocks is a key component of our Campaign to Eliminate Drunk Driving which began in 2006.  We celebrated when Tennessee passed our own All-Offender Ignition Interlock Law in 2013 and again when a compliance-based component was added to strengthen this law in 2016.

To help officers who encounter drivers who have a device installed or who have been ordered to have one installed, we have gathered some information that may be helpful if a citation is needed for violation of this law.
