S.L. 2021-182 (S 183) enacted significant changes to the laws that require certain persons convicted of driving while impaired to have ignition interlock installed on their vehicles. Those changes include: (1) eliminating the 45-day delay for a limited driving privilege to become effective, (2) requiring that ignition interlock be installed only on the vehicle or vehicles the person drives rather than all the vehicles the person owns, (3) requiring that ignition interlock vendors waive a portion of ignition interlock costs for qualified persons, (4) removing the time and purpose restrictions on a limited driving privilege if a person has ignition interlock, (5) changing the alcohol concentration restrictions for ignition interlock from 0.04 and 0.00 to a universal standard of 0.02; and (6) directing a legislative committee to study ignition interlock expansion and related issues.
