Understanding What Happens After a Breath Test Refusal and How Reisig Criminal Defense & DWI Law Can Help Protect You
What Is a Breath Test Refusal in New Jersey?
If you’ve been arrested for a DWI (Driving While Intoxicated) in New Jersey and chose not to submit to a breath test, you’ve likely been charged with what’s known as a “Refusal.” Under New Jersey’s implied consent law (N.J.S.A. 39:4-50.2), every driver operating on public roads automatically agrees to provide a breath sample when requested by law enforcement. Refusing to do so is a separate offense—even if you weren’t convicted of DWI.
A refusal charge carries its own set of serious consequences, including license suspension, fines, and the mandatory installation of an ignition interlock device (IID). Understanding how long that device must remain installed and what it means for your daily life is crucial as you prepare your defense.
What Is an Ignition Interlock Device (IID)?
An ignition interlock device is a small, breath-testing mechanism that’s installed directly into your vehicle’s ignition system. Before starting your car, you must blow into the device. If the IID detects alcohol above a preset limit (typically 0.02%), your vehicle will not start.
The purpose of this law is deterrence—it allows drivers to regain limited driving privileges while ensuring they remain sober behind the wheel. However, the device can be both inconvenient and costly, adding to the already stressful experience of dealing with a refusal charge.
When Is an Ignition Interlock Device Required After a Refusal?
In New Jersey, the IID requirement is mandatory following a breath test refusal conviction. The length of time you must have the device installed depends on whether it’s your first, second, or third offense.
Here’s a general breakdown under current state law:
- First Offense Refusal:
Your driver’s license will be suspended for 7 months to 1 year, and you’ll be required to have an ignition interlock device installed for the entire suspension period plus an additional 6 to 12 months after your driving privileges are restored. - Second Offense Refusal:
The suspension increases to 2 years, and the ignition interlock must remain installed for the suspension period plus 1 to 3 additional years afterward. - Third or Subsequent Offense Refusal:
Your license will be suspended for 8 years, and the ignition interlock will stay on your vehicle for the suspension period plus 1 to 3 years once driving privileges are reinstated.
These penalties can vary based on the specifics of your case, prior record, and whether your refusal occurred alongside another DWI offense.
What Happens If You Fail to Install the Ignition Interlock?
Failing to install an ignition interlock device when ordered by the court is considered a serious violation. If you’re caught driving without the device, you may face additional fines, an extended suspension period, or even potential jail time.
Additionally, your vehicle cannot legally be operated until the device is properly installed and monitored by a state-approved provider. The court will require proof of installation, and removal can only occur once the mandated period has ended.
The Financial and Lifestyle Impact
Installing an IID comes with several costs:
- Installation fees typically range from $100 to $200
- Monthly monitoring fees average $75 to $125
- Removal fees once your period ends
These costs add up quickly and can be financially burdensome. Beyond the expense, there’s the daily inconvenience—each time you start your vehicle, you must blow into the device. Random retests may also occur while driving to ensure ongoing sobriety.
While the IID allows limited driving, it also serves as a public reminder of your legal situation—something most clients find emotionally difficult.
How a DWI Defense Attorney Can Help Reduce or Avoid the IID Requirement
Not every refusal case is straightforward. Many drivers are unaware of their rights when asked to take a breath test. Officers are required to clearly explain the consequences of refusal using a standardized statement. If they fail to read this properly, or if the procedure wasn’t handled correctly, your attorney may have grounds to challenge the charge.
