What is an Ignition Interlock Device (IID)?

An Ignition Interlock Device (IID), also called a car breathalyzer, is a device that measures breath alcohol content (BrAC). It is typically installed in your vehicle as part of an administrative or legal requirement after drunk driving. Learn more about Smart Start's Ignition Interlock here.

How do I know if Smart Start’s devices are compliant with my program?

All of Smart Start’s Ignition Interlock Devices (IIDs) are approved by the National Highway Traffic Safety Administration (NHTSA) and the state of Connecticut.  You can rest assured that, having met these requirements, Smart Start’s Ignition Interlock Devices are compliant with your program. 

Do I need the device on all of my vehicles?

Yes, the state of Connecticut requires that you install the Ignition Interlock Device (IID) on all of your vehicles. 

What if I have a requirement, but I don’t own a vehicle?

In Connecticut, if you have a requirement, but you don’t own a vehicle, you can have the Ignition Interlock Device (IID) installed on a family member’s vehicle or a friend’s vehicle.  You will need a letter of permission from the vehicle’s owner stating that you can install the IID. 

How do the consequences differ for a first and second DWI? Third? Fourth?

Connecticut interlock laws require that, if you are convicted of a DUI, you serve a suspension of 45 days or until your 21st birthday, whichever is longer. After that suspension is complete, you are required to have an Ignition Interlock Device installed for one to three years, depending on prior DUI offenses. You are considered to be DUI if you register .08% or above on a blood-alcohol test. If you are under 21 years old, you are considered to be DUI if you register .02% or over.  When you are arrested for a DUI in Connecticut your license can be suspended in two different ways: 
  • DMV suspension: This only happens if you fail a breath test or refuse to take one. The suspension period generally begins 30 days after your DUI arrest. You will receive a Notice of Suspension from the Connecticut Department of Motor Vehicles (DMV) dictating your period of suspension. Suspension can range from six months to six years, depending on your age, blood alcohol level (BAC) at the time of arrest, and prior record of offenses. 
  • Criminal Court suspension: This occurs when you are sentenced by a court after a trial or plea agreement. 
You will possibly encounter both types of suspension. You will only be eligible for an ignition interlock program after a criminal conviction.  If you are convicted in court for a first or second DUI offense, you can apply for an Ignition Interlock Device (IID) after a 45-day suspension (unless criminal penalties dictate otherwise). If you are under 21, your license suspension lasts until your 21st birthday.  You must serve a minimum of 48 hours in jail or perform 100 hours of community service, and pay a fine.  For second or third offense, in addition to higher fines, you may face vehicle impound or confiscation and permanent license revocation. For a second offense within ten years, you must have an Ignition Interlock Device (IID) installed for three years after the 45-day suspension period.

"This is my first dui(without injury...i was parked, standing outside of my car when the cop approached me and told me i hav2 big eyes. I reaponded tnat yes,i hear that a lot, to which he replied: "no. I think you're drunk.'" Taken aback, I repeatedly offered to do whatever test he wanted even asked to do a breathalyzer.. hour lateri was finally allowws to so whicg Boqwz nthink the officwr sakdand it was only my prescribed meds in my system which their own tox lab clearly states none of which would have caused impairment...this entire ordeal has been absolutely baffling! I was never court ordered to install an IID and my charge isn't even alcohol related so this has been ridiculous to say the least! My attorney was even more shocked than myself upon learning the dld wants me to install this device, especially for such a long duration! "
