New Jersey DWI / DUI Defense Lawyer

A DWI charge in New Jersey is one of the most serious traffic offenses you can face. A conviction can cost you your license, thousands of dollars in fines and surcharges, higher insurance for years, and in many cases an ignition interlock device on your vehicle. New Jersey is also one of the toughest DWI states in the country: there is no plea bargaining a DWI down to a lesser offense, which means your best path to a good outcome is a strong defense. Our attorneys defend drivers charged with DWI and DUI in municipal courts throughout Hudson, Essex, Passaic, Union, Bergen, and Morris Counties, and we know how to find the weaknesses in the state’s case.

DWI Is Not a Crime in New Jersey, but the Penalties Are Severe

New Jersey classifies DWI/DUI as a traffic offense rather than a criminal offense, so a conviction will not give you a criminal record. Do not let that fool you into thinking the stakes are low. The penalties are steep and they escalate sharply with each subsequent offense and with higher blood alcohol concentration (BAC) readings. Because a DWI is handled in municipal court rather than Superior Court, the case moves quickly, which makes it all the more important to involve a defense attorney early.

New Jersey DWI Penalties

New Jersey’s DWI penalties are driven by two things: your blood alcohol concentration (BAC) and whether it is a first, second, or third offense. The current license loss and ignition interlock device (IID) requirements break down as follows:

For a first offense, the consequences scale with your BAC. A first offense with a BAC of 0.08% to 0.099% carries no license suspension and a 90-day ignition interlock requirement. A first offense with a BAC of 0.10% to 0.149% carries no license suspension and an interlock requirement of seven months to one year. A first offense with a BAC of 0.15% or higher carries a three-month license suspension and an interlock requirement of one year to fifteen months.

For a second offense, the penalty is a license suspension of one to two years and an ignition interlock requirement of two to four years.

For a third or subsequent offense, the penalty is an eight-year license suspension and an ignition interlock requirement of two to four years.

Every DWI conviction also carries fines, mandatory time at an Intoxicated Driver Resource Center (IDRC), and significant insurance surcharges that are billed for years after the case is resolved.

The 2025 Interlock Credit: An Alternative to Losing Your License

There is an important recent change in the law that every driver charged with DWI should understand. As of an amendment signed into law on April 3, 2025, a person who would otherwise have to forfeit their driving privileges may, instead of giving up their license, install an ignition interlock device and receive a one-day credit against the suspension period for every two days the device is installed. This credit applies to first, second, and subsequent offenders, and New Jersey may be the only state in the country that allows all alcohol-intoxicated drivers to avoid a loss of driving privileges in this way.

There are limits. The credit is not available if the DWI resulted in serious bodily injury to another person, and it does not apply to offenses involving driving under the influence of narcotic, hallucinogenic, or habit-producing drugs, or to certain commercial driving offenses. The amendment applies to offenses occurring on or after the effective date and is currently set to expire on January 1, 2029. In practice, the best approach is to install the device and obtain a restricted use license from the MVC so it can be presented to the court at sentencing. We can walk you through whether this option makes sense in your case and how to position it properly.

Refusal to Submit to a Breath Test

Under New Jersey’s implied consent law, drivers are deemed to have consented to a breath test when lawfully arrested for DWI. Refusing to provide a breath sample is a separate offense that carries its own penalties, including fines, license consequences, and a mandatory ignition interlock device. You can be charged with both DWI and refusal arising out of the same stop. It is also important to know that the interlock credit described above does not currently apply to refusal charges, so the license consequences of a refusal stand on their own. We defend against both charges, and refusal cases have their own legal requirements that the state must prove, which can create openings for the defense.

How We Defend DWI Cases

The state has to prove its case, and a DWI prosecution has many moving parts that have to be done correctly. We examine every one of them. The stop itself must be lawful: if the officer did not have a valid reason to pull you over, the evidence that followed may be suppressed. The field sobriety tests must be administered according to standardized procedures, and we look at whether they were. The Alcotest breath testing device must be properly calibrated and maintained, the operator must be certified, and the law requires an uninterrupted 20-minute observation period before the test is given. A failure in any of these areas can undermine the reliability of a breath reading. Where blood was drawn, we scrutinize the chain of custody and the testing procedures. We obtain and review the discovery in your case, including the police report, dashcam and body camera footage, and the device records, and we build the defense around what that evidence actually shows.

Why Acting Quickly Matters

DWI cases move fast in municipal court, and some of the most valuable evidence, like dashcam and body camera footage, can be subject to retention limits. The sooner a defense attorney is involved, the sooner we can request and preserve that evidence, identify the weaknesses in the state’s case, and start building your defense. Acting early also gives you the chance to install an ignition interlock device and begin accruing credit toward your license penalty before your case is even resolved. Waiting can cost you options.
