Restricted License with IID

New York issues a conditional license with IID that allows driving to work, school, medical appointments, and court-ordered treatment programs. The conditional license replaces the old pre-conviction conditional license system.

Tampering / Circumvention Penalties

Tampering with an IID in New York is a Class A misdemeanor carrying up to 1 year in jail. The IID requirement is extended and the conditional license may be revoked.

Early Removal

New York allows early removal after completing the minimum period with no violations, with court approval.

New York-Specific Notes

New York requires IID for all DWI convictions as a condition of probation and any conditional license. Since Leandra's Law (2009), IID has been mandatory for all first-time DWI offenders. New York distinguishes between DWI (BAC 0.08%+) and DWAI (BAC 0.05-0.079%); IID is mandatory for DWI but discretionary for DWAI.
