In July of 2009, Minnesota implemented a statewide Ignition Interlock Device Pilot Program. The Ignition Interlock Program allows Minnesota drivers who have had their licenses revoked due to multiple DWI convictions get their licenses back sooner, if they agree to install an ignition interlock device in their car. There are many benefits to this program. For example, it allows DUI offenders to get to court and probation appointments as well as work and alcohol counseling sessions. The Ignition Interlock Device protects the public by not allowing the car to start if the device registers alcohol on the driver’s breath. The Ignition Interlock Devices being used in Minnesota are equipped with a camera, so there is no question as to who is actually providing the air sample. In addition to the primary benefit of protecting the public, other interlock benefits include helping the DUI offender avoid future DUI arrests, allowing the user to drive legally, and preventing operating after suspension charges by giving the DWI offender a restricted license.
The Massachusetts Ignition Interlock Device Law has been in effect since 2006. Although there are thousands of devices in use, there have been some false positive problems with the Interlock Devices in Massachusetts.
