Vermont DUI Ignition Interlock Device
An Ignition Interlock Device (IID) is a small mechanism installed in a car to measure the Blood Alcohol Content (BAC) of the driver using a breath test. The device is attached to the ignition, and its main function is to prevent the car from starting if a given breath sample shows a BAC of over .02. If a driver fails the test, the instrument prevents the car from starting for a period of time known as the lockout period.
The device also monitors a driver's breath with a "rolling retest" while the car is moving in order to prevent an intoxicated person from asking a sober person to take the initial test and start the car. If the driver fails the rolling retest, the device will trigger either an alarm or the car's horn, and it won't stop until the car is shut off.
Who Are Ignition Interlock Devices Issued For?
It is rare in Vermont for a first-time drunk driving offender to be ordered to install an IID, unless their BAC was extremely high. Usually it is a punishment reserved for repeat DUI offenders, those convicted of an aggravated DUI, those found to be transporting a minor in the car during the time of arrest, or again, if the BAC was extremely high.
Cost and Maintenance
As in most states, in Vermont the installation, maintenance, and all other associated costs of an IID are paid for by the driver. Exact costs vary depending on the installer and type, but it will be at least a couple hundred dollars.
Restricted Driver's License
A Restricted Driver's License (RDL) allows a driver the ability to operate a non-commercial vehicle for the purpose of getting to work, medical appointments, and school. If you were issued an IID then you will need to apply for RDL as well.
Consequences of failing an IID test
There are a number of ways a driver can misuse an IID resulting in a permanent lockout and the immediate revocation of their RDL:
-Missing a service date or failing to properly maintain the device
-Attempting to destroy, tamper or bypass the IID
-Refusing three or more rolling retests
Aside from license suspension, drivers could face other serious penalties as well for misusing the device.
