person to provide proof of compliance to the court or the probation officer within thirty days.
If the person fails to provide proof of installation within that period, absent a finding by the
court of good cause for that failure which is entered into the court record, the court shall
revoke the person's probation.
H. The person whose driving privilege is restricted pursuant to this Section shall
have the system monitored by the manufacturer, at the manufacturer's expense, for proper use
at least every thirty days, and more frequently as the court may order, on the operation of
each ignition interlock device in the person's vehicles. A report of monitoring shall be issued
by the manufacturer to the court and the department within fourteen days after the system is
monitored. However, the report issued to the department shall be in an electronic format
specified by the department.
I. If a person is required to operate a motor vehicle in the course and scope of his

device as a requirement of bail, a part of a pre-trial diversion program, or a term of a
suspended or deferred sentence as provided in Code of Criminal Procedure Article 894.
(4) The Department of Public Safety and Corrections shall promulgate such rules and
regulations as are necessary to implement the provisions of this Subsection.
