Requires mandatory placement of ignition interlock devices on all vehicles owned or operated by persons convicted of driving under the influence, with installation periods varying by offense severity and prior convictions.

Lowers the blood-alcohol threshold at which ignition interlock devices prevent vehicle operation from 0.05% to 0.025%, and makes tampering with devices unlawful if done to provide the restricted person with an operable vehicle.

Establishes "ignition interlock licenses" allowing drivers whose licenses are revoked for DUI to obtain restricted driving privileges during revocation periods, with day-for-day credit toward mandatory interlock device periods upon completion of substance abuse education courses.

Provides for ignition interlock licenses for persons with permanently revoked driving privileges, requiring mandatory device installation on all vehicles owned or operated by the convicted person.

Restricts removal of ignition interlock device requirements until the device vendor certifies that no prohibited incidents (high breath-alcohol levels, missed retests, maintenance failures) occurred during the preceding 4 consecutive months.
