Ignition Interlock Device
When You Should Call A St. Louis DUI Defense Lawyer
An ignition interlock device is a device connecting to your vehicle that
prevents you from operating your car with a measurable blood alcohol level.
If any alcohol is measured in the mouth, the engine of the vehicle will
not start. In July 2008, Senate Bill 930/947 was passed, affecting all
future repeat offenders of Missouri's DWI laws. This bill will also
affect any past repeat offenders that have not had their driving privileges
partially or fully reinstated before July 1, 2009.
Under this new law, if you already have a previous
on record and you received an additional suspension or revocation for
DWI, or if you refuse to submit to an alcohol or drug test, you may have
to have an ignition interlock device installed in your vehicle before
your driving privilege can be reinstated. This new law also applies to
Missouri drivers with alcohol-related offenses from other states.
How does an ignition interlock device work?
An ignition interlock device works to prevent someone that has previously
been convicted of driving under the influence from repeating their actions
and getting behind the wheel after drinking.
These devices are able to prevent a car from starting by:
- The driver must blow into the mouthpiece before being able to start their car;
- The fuel cell located inside the ignition interlock device analyzes the
blood alcohol content in the breath; and
- If the BAC is below a certain limit, the vehicle will start; or
- If BAC is above the certain limit, the fuel cell will remain open and the
car will not stop.
In order to prevent someone from asking a sober passersby or friend to
blow into the device for them, ignition interlock devices have a built-in
system that will require a driver to breathe into them while driving to
ensure that they are sober. This information will be recorded and sent
How can I get an ignition interlock device?
The installation of the IID must be completed by an approved vendor, and
is normally in place for a minimum of six months. During this time period,
you will be required to report to a certified IID vendor each month for
maintenance to ensure the device is working properly. Failure to comply
with this maintenance requirement will mean the
suspension of your driving privileges. At this point, to have your driving privileges reinstated, you will have
to go to an approved vendor, get the IID reinstalled or serviced, send
proof to the Driver's License Bureau of the installation or service,
and pay the required $20 reinstatement fee.
In certain situations, the court may impose a longer period for the IID.
Failure to install the IID will lead to the revocation of your driving
privileges for one year. A second offense will result in the loss of driving
privileges for five years.
For individuals that refuse to submit to an alcohol or drug test, this
new law will require you to file proof of automobile liability insurance
with the Department of Revenue to get your license reinstated. This proof
of insurance must be filed with the Department of Revenue for a two-year
period from the date of revocation. The most common proof of insurance
is the SR-22, which will be filed by your insurance carrier. In addition,
you may be required to pay a reinstatement fee, and complete SATOP (
Substance Abuse Traffic Offenders Program).
