If you’ve been charged with DWI in North Carolina, you may be eligible for a limited driving privilegethat allows you to legally drive under certain conditions while your license is revoked. One of the most common questions drivers ask is:
“Will I need an ignition interlock device to get a limited driving privilege?”
Under North Carolina law, interlock is only required if your blood alcohol concentration (BAC) was 0.15 or higher.
What Is a Limited Driving Privilege?
A limited driving privilege is a court order that allows restricted driving after a DWI revocation. It is governed by N.C. Gen. Stat. § 20-179.3.
If granted, you may drive only for specific purposes, including:
• Work
• School
• Court-ordered treatment
• Household maintenance
• Medical emergencies
The court will also limit days, times, and locations you are allowed to drive.
When Is Ignition Interlock Required?
BAC of 0.15 or Higher
This requirement is found in N.C. Gen. Stat. § 20-179.3(g3).
If your BAC was 0.15 or above, the statute mandates:
• Installation of an ignition interlock device
• Use of interlock even for limited driving privileges
• Compliance before you are legally allowed to drive
There are no judicial exceptions when BAC is .15 or higher.
- When Interlock Is NOT Required
If your BAC was below 0.15, North Carolina law does not require ignition interlock for a limited driving privilege.
You may qualify without interlock if:
• Your BAC was 0.14 or lower
• You meet eligibility under N.C. Gen. Stat. § 20-179.3(b)
• The court grants the privilege
Insurance points typically remain on your record for three years, and during this time, they will continue to affect your premiums. DWI remains on for five years.
What Is an Ignition Interlock Device?
An ignition interlock device is a breath-testing system installed in your vehicle. You must blow into it before starting the car. If alcohol is detected, the vehicle will not start.
You are responsible for:
• Installation fees
• Monthly monitoring costs
• Calibration appointments
Failure to comply can result in revocation of your privilege and additional charges.
Limited Driving Privileges Are NOT Automatic
Even if you qualify, a limited privilege:
• Requires proper filings
• Must be approved by a judge
• Has strict statutory requirements
• Can be denied if timing or paperwork is wrong
Why Hire a North Carolina DWI Lawyer?
A skilled attorney can:
• Confirm eligibility
• Determine if interlock is required
• Draft the privilege correctly
• Structure legal driving hours
• Prevent costly mistakes
One error can lead to denial or new criminal charges.
Bottom Line
Ignition interlock is only required if BAC was 0.15 or higher.
Lower BAC cases may qualify without interlock.
Limited privileges are technical and court-controlled.
