Final answer:
The minimum IID installation period for a first DUI conviction varies by state and circumstances, but in California it is typically 5 months.
Step-by-step explanation:
The minimum ignition interlock device (IID) installation period for a first DUI conviction varies depending on the state and the specific circumstances of the case. However, as an example, in California, the IID installation period for a first-time DUI conviction is typically 5 months.
An IID is a device installed in a vehicle that requires the driver to pass a breathalyzer test before starting the car and at regular intervals while driving. It is used as a measure to prevent driving.
Other states may have different installation periods for first-time DUI convictions, so it is important to consult the specific laws in your state or jurisdiction.
