North Carolina Ignition Interlock DWI Laws

Information on North Carolina’s DWI and Ignition Interlock Laws

North Carolina has both administrative and criminal sanctions for driving under the influence. If you are arrested for driving with a blood alcohol concentration (BAC) of greater than .08 or if you refuse to take a chemical test, your license will be immediately suspended for 30 days. You can apply for a limited driving privilege after 10 days, but you must wait out your full 30-day suspension before driving again. You will need to install an ignition interlock.

Criminal sanctions for DWI are in addition to the administrative actions. There are five levels of DWI penalties if you are convicted by a court or plead guilty to DWI in North Carolina. For a 1st offense, you will be required to complete 24 hours to 60 days in jail and pay a $200 fine. Judges can suspend jail time and order community service after you spend 24 hours in jail, but you must not drive for 30 days.

Penalties increase with subsequent convictions, up to and including vehicle forfeiture.

Interlock Process

North Carolina ignition interlock laws require that any driver convicted of driving while intoxicated (DWI) for the 2nd time, and also drivers convicted for the 1st time with a blood alcohol concentration (BAC) of .15 or higher, must install an ignition interlock device, including an electronic log device, on every vehicle they own or which is registered to them.
