(a) In addition to any other provision of probation, upon a second or subsequent conviction of a resident of this state for violating Code Section 40-6-391 within five years, as measured from the dates of previous arrests for which convictions were obtained to the date of the current arrest for which a conviction is obtained, for which such person is granted probation, the court shall order as conditions of probation that:

(1) Such person shall have installed and shall maintain in each motor vehicle registered in such person's name throughout the applicable six-month period prescribed by subsection (b) of Code Section 42-8-112 a functioning, certified ignition interlock device, unless the court exempts the person from the requirements of this paragraph based upon the court's determination that such requirements would subject the person to undue financial hardship; and

(2) Such person shall have installed and shall maintain in any other motor vehicle to be driven by such person during the applicable six-month period prescribed by subsection (b) of Code Section 42-8-112 a functioning, certified ignition interlock device, and such person shall not during such six-month period drive any motor vehicle whatsoever that is not so equipped.

For the purposes of this subsection, a plea of nolo contendere shall constitute a conviction; and a conviction of any offense under the law of another state or territory substantially conforming to any offense under Code Section 40-6-391 shall be deemed a conviction of violating said Code section.

(b) Any resident of this state who is ordered to use an ignition interlock device, as a condition of probation, shall complete the DUI Alcohol or Drug Use Risk Reduction Program and submit to the court or probation department a certificate of completion of the DUI Alcohol or Drug Use Risk Reduction Program and certification of installation of a certified ignition interlock device to the extent required by subsection (a) of this Code section.

(c) In the case of any person subject to the provisions of subsection (a) of this Code section, the court shall include in the record of conviction or violation submitted to the Department of Public Safety or its successor agency notice of the requirement for, and the period of the requirement for, the use of a certified ignition interlock device. Such notice shall specify any exemption from the installation requirements of paragraph (1) of subsection (a) of this Code section and any vehicles subject to the installation requirements of paragraph (2) of said subsection. The records of the Department of Public Safety or its successor agency shall contain a record reflecting mandatory use of such device and the person's driver's license or limited driving permit shall contain a notation that the person may only operate a motor vehicle equipped with a functioning, certified ignition interlock device.

(d) Except as provided in Code Section 42-8-112, no provision of this article shall be deemed to reduce any period of driver's license suspension or revocation otherwise imposed by law.

(e) The fee for issuance of any driver's license indicating that use of an ignition interlock device is required shall be as prescribed for a regular driver's license in Code Section 40-5-25, and the fee for issuance of any limited driving permit indicating that use of an ignition interlock device is required shall be as prescribed for a limited driving permit in Code Section 40-5-64; except that, for habitual violators required to use an ignition interlock device as a condition of a probationary license, the fee shall be as prescribed for a probationary license in Code Section 40-5-58.
