An ignition interlock is a device that is installed on your vehicle and
requires that you blow into the device before driving. It measures the
blood alcohol concentration on your breath to determine if you have been drinking.
For those convicted of their first offense of driving while intoxicated
in Maryland and their blood alcohol concentration was .15 or higher, an
ignition interlock is required for one year as a part of sentencing. The
court, however, has the option of ordering the defendant to only operate
vehicles that have an ignition interlock for one to three years.
Those whose driver’s licenses are suspended because of the state’s
point system for a DWI conviction may get a restricted license by participating the
Ignition Interlock Program. Those who are subject to revocation of their driver’s licenses
because of a DWI may participate in the IIP in order to have theirs suspended
instead. Someone who is considered a habitual offender because of a fourth
or subsequent offense must participate in the IIP for at least 24 months.
There are costs associated with this program, including for the installation
and maintenance of the ignition interlock. Furthermore, there is a fee
for a restricted driver’s license and a fee to have the restriction
removed from your license.
As you can see, the IIP can help those who are facing suspension or revocation
for DWI and other alcohol-related driving offenses. An experienced criminal
defense attorney can provide more information about the IIP and how it
may apply to your current case or conviction for DWI.
