I wrote last week about changes to North Carolina’s ignition interlock statutes that were effective June 1, 2022. As I noted in that post, one of those changes was to eliminate the time and purpose restrictions that otherwise apply to limited driving privileges if ignition interlock is required as a condition and the person is driving a designated vehicle equipped with ignition interlock. Another was to require vendors to waive a portion of ignition interlock costs for a person ordered by a court or required by statute to install ignition interlock but who is unable to afford the system. These changes and others enacted by S.L. 2021-82 were recommended by the Ignition Interlock Subcommittee of the Statewide Impaired Driving Task Force as part of a package of reforms designed to expand the use of ignition interlock and, in turn, to improve traffic safety. It remains to be seen whether the legislation will have that effect.
One determinant may be whether drivers see the benefit of broader driving privileges as being worth the cost of ignition interlock. A judge may be more likely to impose the condition when it is sought by an applicant. Another factor may be whether judges believe that ignition interlock is an effective countermeasure to impaired driving (researchers in fact identify interlock as among the leading countermeasures) and whether ignition interlock requirements in limited driving privileges are enforced in practice. This post addresses this last issue by reviewing the mechanisms for enforcing ignition interlock requirements and the sanctions for violation of ignition interlock conditions imposed by a court as part of a limited driving privilege.
