Understanding the Ignition Interlock Device (IID) and Its Legal Implications

Definition & meaning

An ignition interlock device (IID) is a breathalyzer installed in a vehicle that measures a driver's blood alcohol concentration (BAC) before allowing the engine to start. The device requires the driver to blow into it, and if the BAC exceeds a predetermined limit, the vehicle will not start. IIDs are often used as a condition for individuals convicted of driving under the influence (DUI) to regain their driving privileges, ensuring that they do not operate a vehicle while impaired.

Example 2: A first-time DUI offender in California may be required to install an IID for six months as part of their probation, allowing them to drive legally while ensuring they do not consume alcohol.
