Is An ignition interlock device cannot be required for first conviction of DUI?

An ignition interlock device (IID) may not be required for a first DUI conviction in some jurisdictions, but laws vary by state. In many places, first-time offenders may face less severe penalties, while others may mandate the use of an IID regardless of prior convictions. It's essential to check the specific regulations in the state where the conviction occurred to determine the requirements.
