Drunk/Drug Driving Laws
Guide to Ignition Interlock Devices
After a habitual drunk driver has served the minimum period
of revocation/denial, he or she may be eligible for a Driver
License Appeal hearing. If the hearing is held after October
1, 1999, and the person is authorized for a restricted license,
the hearing officer must order the installation of an ignition
interlock device in any vehicle the person intends to operate.
The interlock device must be installed for the first year
of license restrictions. The person cannot drive until after
the interlock device has been installed on the vehicle and
proof of installation has been submitted to a local branch
office of the Secretary of State by your provider.
The state does not regulate the cost of ignition interlock
devices. However, the Legislature did limit the amount that
can be charged to people on low-incomes to a maximum of
$2 per day. In order to qualify for this reduced fee your
income must fall below 150% of the current Poverty Guidelines
of the U.S. Secretary of Health and Human Services. To determine
if you may qualify, see your provider for details. The state
law does require copies of the previous year filed State
Income Tax forms for verification.
You must drive with an Ignition Interlock installed on your
vehicle and a valid driver's license for at least 1 full
year. You may then petition the Drivers Assessment and Appeal
Division (DAAD) for a hearing. At that hearing you must
present your final report issued by your provider to establish
the mandatory minimum length of installation required by
