DWI / DUI
Understanding New Jersey's implied consent law
Shugar Law Office defends New Jersey breath-test refusal charges, and the DWI charges that usually accompany them, from its Mount Holly office. If you drive in New Jersey, you've already agreed to take a breath test after a lawful DWI arrest: refusing is its own offense, and the penalties changed completely in the 2019 and 2024 overhauls, so most of what you'll read online about "mandatory one-year suspensions" is years out of date.
The Law
What implied consent means
Under New Jersey's implied consent statute, accepting the privilege of driving here includes consenting in advance to an evidential breath test when you're arrested on probable cause for DWI. Refuse that test and you're charged under N.J.S.A. 39:4-50.4a, a separate offense that rides alongside any DWI charge.
The refusal charge has its own elements the State must prove, including probable cause for the arrest, a request to submit to the breath test, required warnings, and a refusal. The exact facts matter: counsel reviews which standard statement was read, what the officer said and recorded, the response, timing, and the basis for the arrest. A disputed element creates an issue to evaluate; it does not guarantee a dismissal.
Two things implied consent does not cover. It doesn't reach roadside field sobriety exercises or the handheld screening device; declining those isn't a refusal offense. And a refusal is not an "admission of guilt" to DWI, whatever older articles claim. The state still has to prove intoxication with other evidence. It just also gets to prosecute the refusal itself.
Current Penalties
Refusal penalties today: interlock, not fixed suspensions
New Jersey rebuilt its drunk-driving penalties around the ignition interlock device (IID), first in December 2019 and again effective February 19, 2024 — the current interlock rules are covered tier by tier in our interlock guide. Refusal now works like this:
| Offense | License | Fine | Ignition interlock |
|---|---|---|---|
| First refusal | Forfeited only until the IID is installed | $300–$500 | 9–15 months |
| Second refusal | Forfeiture of 1–2 years following IID installation | $500–$1,000 | 2–4 years after restoration |
| Third refusal | 8-year forfeiture | $1,000 | Required during and after |
Notice what's missing: the old fixed suspensions. A first refusal no longer means a year without driving; it means driving on an interlock for 9 to 15 months, which is a very different life. Refusal also brings Intoxicated Driver Resource Center requirements and the usual assessments, and a refusal conviction counts against you if there's ever a next time.
Two more current-law points worth knowing. Since the 2024 amendments took effect, plea agreements are expressly authorized in DWI and refusal cases on the prosecutor's recommendation, ending New Jersey's decades-old plea-bargain ban in these matters; that changed the negotiating landscape substantially. And the 2023–24 amendments carry a sunset date of January 1, 2029, so this framework is due for legislative revisiting.
The Real Question
DWI and refusal are separate charges
A refusal does not erase the underlying DWI allegation. The State may proceed on driving, observations, field testing, statements, and recorded evidence, while separately prosecuting the alleged refusal. Counsel reviews the stop and arrest, the request and warnings, the response, refusal paperwork, body-camera or station video when available, and any evidence supporting the DWI charge.

Common Questions
Implied consent questions, answered
Can I refuse the breathalyzer in New Jersey?
You can physically refuse, but it is a separate offense with its own penalties. By driving on New Jersey roads you have already impliedly consented to a breath test after a lawful DWI arrest. A first refusal means losing your license until an ignition interlock is installed, a $300 to $500 fine, and 9 to 15 months on the interlock.
If I refuse, does that count as admitting I was drunk?
No. Refusal is not an admission of guilt, and the state still has to prove any DWI with other evidence, such as driving observations and field sobriety tests. But refusing does not make the DWI go away either — you can be convicted of both the refusal and the DWI in the same case.
Does implied consent cover roadside tests too?
No. Implied consent applies to the evidential breath test at the station. Roadside field sobriety tests and the handheld preliminary breath device are not part of the implied consent law, and declining them is not a refusal offense — though officers can still arrest you based on their other observations.
Can a refusal charge be beaten?
Yes, refusal cases have real technical defenses. The state must prove a lawful arrest based on probable cause, that the standard statement was read to you properly, and that your response was actually a refusal. Ambiguous answers, language issues, and procedural shortcuts all get litigated — and since 2024, plea agreements are authorized in refusal cases too.
Charged with refusal, DWI, or both?
These cases turn on procedure, and procedure is checkable. One call, no charge, and you'll know where the state's case is weak and what your license realistically faces.
