The Ignition Interlock Device

The ignition interlock device is a tool law enforcement uses to ensure that individuals do not drive under the influence of alcohol. The courts require most devices to be installed in a vehicle after the driver has been found guilty of driving while impaired. Anyone required to have this device should understand how it works and how to avoid any further complications with the law.

How the Ignition Interlock Device Works

The ignition interlock device is a system that detects alcohol on the breath of the driver. In order to start the vehicle to use it, the driver must blow into the alcohol sensor unit. This device is generally attached to the dashboard of the vehicle. The vehicle will not start unless this device is blow into properly and the BAC of the driver is above a specific level. In most states, this level is set between .02 and .04 percent BAC.

There are several things to know about this device, in order to use it properly.

• Individuals must blow into the device to use the vehicle at all.
• Every few minutes while driving, the individual needs to blow into the device again, to ensure that his or her breath still remains alcohol free. This is called the rolling or running retest.
• Allowing a friend to blow into the ignition interlock device and then getting behind the wheel will not work. The vehicle will shut down if the driver fails the running retests.

Many courts require that the vehicle have the device installed for a long term, depending on the actual case and the laws within the state. However, many locations will require that the vehicle owner bring in the vehicle for inspection every 30 to 60 days to ensure the interlock device has not been tampered with in any way.

In many states, the ignition interlock device is part of the laws for driving under the influence of drugs. Each state sets standards on when and how such devices must be used. A judge may order the installment of the device if the individual has been found guilty of driving under the influence or fails other tests.

Hiring an Attorney

Individuals who are facing DUI should contact an attorney. An attorney can help get the sentence reduced and in some cases can help individuals to stop the installment of an ignition interlock device, if possible. It is always a good idea to use an attorney in this type of case since it has significant consequences on the individuals criminal and driving records.
