Ignition Interlock Devices in Connecticut

An engine interlock device is a machine which can be installed in a motor vehicle which will not allow the motor vehicle to start until after the driver has passed a breath test.  Once the vehicle has been started, the machine will randomly require an additional sample be provided.  The driver is required to pay all costs for the device’s installation and maintenance.  These costs include a $100 fee to the DMV to amend the driver’s record to include notification of the use of the interlock device and make the new record available to law enforcement.

The court may, at its discretion, require an interlock device be installed as part of a sentence for DUI.  The statute requires that an interlock device be installed on the driver’s vehicle if he has been convicted of his second DUI in the past 10 years.

The statute makes it a separate crime to tamper with the interlock device or persuade another person to provide a breath sample for the machine to test.  Attempting to bypass the machine in either of these ways is a Class C misdemeanor.  A defendant is also guilty of a Class C misdemeanor if he drives a car which does not have an ignition interlock installed when he has been ordered by a court to only drive in vehicles where the device has been installed.  A class C misdemeanor is punishable by a fine of up to $500 and a prison term of up to three months.
