What New Jersey requires
New Jersey ties the interlock term to your blood alcohol reading, not just to the fact of a conviction. Since 2024 you may fit a device voluntarily after arrest and before conviction, which can cut the fine and shorten the suspension. Skip it and the court must suspend your license indefinitely until you install one — the device is what gets you driving again.
- First offense: 3 months at 0.08–0.10% BAC; 7–12 months at 0.10–0.15%; 12–15 months at 0.15% or higher
- Lockout threshold: Set by the state device specification; the Motor Vehicle Commission designates the facilities that install and service the device
- Program run by: New Jersey Motor Vehicle Commission, on the sentencing court order
Why New Jersey orders these devices
An interlock order is not a judgment about you personally — it is what the state does with every case of this kind, and the reason sits in the crash record.
Source: NHTSA Fatality Analysis Reporting System, 2020–2022. The count covers fatal crashes where police recorded that a driver had been drinking, which is narrower than the federal 0.08 BAC measure and therefore understates the real figure. Somerset County runs at or below the New Jersey average — the requirement is set state-wide regardless. What the device changes is measurable too: a car fitted with one cannot be started over the limit, which is why the order attaches to driving privileges rather than to the sentence.

Interlock questions in Green Brook
Where can I get an ignition interlock device installed in Green Brook, NJ?
We index 1 certified installation point in Green Brook, run by Intoxalock. Addresses are listed above. Book with the provider your paperwork names, not the nearest one — a device approved in one state is not automatically approved in the next, and switching brands mid-term means a second installation fee.
How much does it cost to have an ignition interlock device installed in New Jersey?
New Jersey does not publish a price, so the honest answer is the national one: NHTSA puts installation at $70 to $90 and monitoring at about $70 a month, roughly $3 to $4 a day. Quotes in Green Brook will sit around that unless the provider is charging for something the state does not require.
Can I drink one beer and still start the car in New Jersey?
Almost certainly not. New Jersey does not print one fixed number in the statute — the level is set by the certifying agency in the device standard, typically between 0.02% and 0.025% BAC, far below the 0.08% driving limit. The device is not testing whether you are impaired, it is testing whether you drank. One drink shortly before a test is enough on most programs, and the fail is recorded whether or not you try again.
What does an ignition interlock device do?
An ignition interlock is a breath-alcohol tester wired into your car ignition. You blow into it before starting the engine; if your breath alcohol is above the state threshold, the engine will not start.
While you are driving, the device asks for rolling retests at random intervals. Every sample, skipped test, and lockout is recorded and sent to the agency monitoring your case.
