WHEN IS AN IGNITION INTERLOCK GENERALLY REQUIRED IN NORTH CAROLINA FOR DRIVING WHILE IMPAIRED (DWI) CASES?
For first time offenders who are convicted with a breath or blood alcohol (BAC) result of 0.15 or higher a mandatory 1 year interlock requirement will be imposed. Also, first time offenders who are convicted with a BAC below 0.15 although not a mandatory requirement, a judge may still in their discretion order one. For a person who incurs a second conviction of DWI within 3 years from their first DWI conviction, a 1 year ignition interlock requirement will be imposed upon eligibility for restoration of privileges. Additionally, for a person who incurs a third conviction of DWI or conviction of Habitual DWI (3 or more within 10 years) a 3 years ignition interlock requirement is likely to be imposed upon eligibility of restoration of privileges.
Positive take aways (if you can call them that), under current law you no longer have to suffer through the 45 days of non-operation before you can get an interlock privilege associated with a result of BAC.15 or higher; and there are no time restrictions on this type of interlock privilege.
