Yes. Your ignition interlock device allows you to operate your car only if your blood alcohol content (BAC) is below 0.025%. For every three breath tests that you fail in a 12-month period, the Colorado DMV will extend your interlock requirement for an additional year. You are entitled to a DMV hearing to contest the extension of the interlock restriction. And if you choose not to extend the lease on your IID, the DMV will suspend your license instead - preventing you from driving at all during the suspension period.
