The defendant is required to pay a $10 monthly monitoring fee to Williamson County. The defendant will also pay the interlock vendor for the installation and a monthly lease fee for the device. The monthly lease fee will vary depending on the interlock company.
You should discuss this with your attorney. If you don't have an attorney you may hire your own, or if you cannot afford to hire your own attorney, you may request a court appointed attorney using the link below..
If the defendant fails to install the interlock device by the court ordered deadline or fails to pay the monthly fees, a warrant may be issued.
If you have questions regarding basic operation of the device such as physical installation, how to use or manage the device, how to transfer the device from one vehicle to another, physical removal or return of the device, please contact the ignition interlock company directly.
