HB 1423 -- Ignition Interlock Devices Sponsor: St. Onge This bill specifies that anyone who has had his or her driving license and privilege suspended due to an alcohol-related traffic offense will be deemed to have not fulfilled the suspension and a restricted driving privilege will not be issued until the person has completed 30 days of a suspension and has filed proof with the Director of the Department of Revenue that his or her motor vehicle is equipped with a functioning, certified ignition interlock device as a required condition of the person's restricted driving privilege. If the person fails to maintain the proof, the restricted driving privilege will be terminated or his or her license suspended, or both.Copyright (c) Missouri House of Representatives
