An ignition interlock device (IID), many times referred to as a Breath Alcohol Ignition Interlock Device (BAIID), is slightly larger than a cell phone and is wired to the vehicle's ignition. These devises can generally be installed quickly. After installation it will require your breath sample before the engine will start. If the ignition interlock detects alcohol on your breath the engine will not start. As you drive the devise will periodically require additional breath samples to insure the absence of alcohol in your system.
It will not prevent all impaired driving but if used consistently it will lead to a substantial reduction in the rate of repeat drunk driving offenders. Ignition interlocks work best when combined with other drunk driving prevention programs.
Anyone can have an ignition interlock system installed on their vehicle. Parents may install a system to insure the safety of the young drivers in the family or a court may require one to be installed on any vehicle that someone convicted of a DWI drives.
Currently there are four companies certified in Rhode Island to lease, sell and install ignition interlock systems. Each provider markets a different device and each has their own fees and policies. Below is the contact information for these companies.
