DUI, DWI & Refusal Lawyers in New Jersey

DUI as a Quasi-Criminal Action

In New Jersey, a DUI or DWI is not considered a criminal offense. Rather, a DUI, alcohol or other drug-related offense punishable in court is called a quasi-criminal action.

Nonetheless, DUI consequences can be severe — especially if your attorney is not experienced in handling these unique and complex cases.

Quasi-criminal offenses are “a class of offenses against the public ‘which have not been declared crimes, but wrongful against the general or local public which it is proper should be repressed or punished by forfeitures and penalties’” (State v. Laird, 25 N.J. 298, 302-03 (1957)).

Elements of a DUI in New Jersey

A person is guilty of DUI in New Jersey if they operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08% or higher. However, drivers can also be convicted with a lower BAC if their ability to drive is impaired.

To secure a DUI conviction, the prosecution must establish:

Operation of a Vehicle – The defendant was in control of a motor vehicle.
Impairment – The defendant was under the influence of alcohol, drugs, or a combination that impaired their ability to drive safely.
BAC Level – If the BAC is 0.08% or higher, this serves as per se evidence of intoxication.

Under New Jersey’s implied consent law, drivers must submit to a breathalyzer test when lawfully requested by law enforcement. Refusing this test carries separate charges and penalties.

Elements of a Refusal Offense in New Jersey

Under New Jersey’s implied consent law, drivers must submit to a breathalyzer test when lawfully requested by law enforcement. Refusing this test carries separate charges and penalties.

To prove a refusal violation, the prosecution must show:

Probable Cause – The officer had reasonable suspicion that the driver was under the influence.
Arrest – The driver was lawfully arrested for DUI.
Test Request – The officer informed the driver of the legal requirement to take the test.
Refusal – The driver refused to submit to the breath test.

Penalties for DUI in New Jersey (Post-2021 Law Updates)

The penalties for Driving Under the Influence in New Jersey depend on your blood alcohol contents as well as whether or not you are a prior offender.

DUI Penalties for Your First DUI Offense in NJ:

For your first offense you can expect to be required to pay a Fine of $250-$500, face Jail time of up to 30 days and be required to complete 12-48 hours with the Intoxicated Driver Resource Center (IDRC).

You may also encounter license suspensions or required Ignition Interlock Device installation, based on your Blood Alcohol Content:

For a BAC of 0.08%-0.10% you can expect the following proposed penalties:

Ignition Interlock Device (IID): Installation for 3 months
No mandatory license suspension, but driving privileges require IID installation.

For a BAC of 0.10%-0.15% you can expect the following proposed penalties:

Ignition Interlock Device (IID): Installation for 7–12 months
No mandatory license suspension, contingent on IID installation

For a BAC of over 0.15% you can expect the following proposed penalties:

License Suspension: 4–6 months
Ignition Interlock Device (IID): Installation during suspension and for 9–15 months after restoration.

DUI Penalties for Repeat DUI Offenses in NJ:

For your second offense, regardless of BAC, you can expect to encounter the following potential penalties

Fine: $500–$1,000
Jail Time: 48 hours to 90 days
Required Community Service: Up to 30 days

Potential Jail Time: 180 days
IDRC: As determined
License Suspension: 8 years
IID: Required during suspension and for 2–4 years after restoration.

The severity of these potential consequences is why it is essential to hire a high quality and caring DUI attorney.

Penalties for Refusal in New Jersey

Refusing a chemical test results in separate penalties, even without a DUI conviction:

First Offense

Fine: $300–$500
IDRC: 12–48 hours
License Suspension: Until IID installation
IID: Required for 9–15 months

Second Offense

Fine: $500–$1,000

License Suspension: 1–2 years (after IID installation)
IID: Required for 2–4 years after restoration

Third or Subsequent Offense

Fine: $1,000

License Suspension: 8 years (after IID installation)
IID: Required for 2–4 years after restoration

If the court sentences you to have an interlock device installed, you will receive a notice of suspension from the New Jersey Motor Vehicle Commission with instructions on how to obtain the device. Failure to install the device could result in an additional one-year suspension of your driving privileges. Additional license suspension and interlock device time depends on the specifics of your case.

What Constitutes a Drug DUI in New Jersey?

Under N.J.S.A. 39:4-50, a person can be convicted of a drug DUI if they operate a motor vehicle while under the influence of a narcotic, hallucinogenic, or habit-producing drug. Unlike alcohol DUIs, there is no legal threshold like a BAC limit; instead, conviction depends on evidence such as:

Erratic driving behavior observed by law enforcement
Field Sobriety Test (FST) performance
Drug Recognition Expert (DRE) evaluation
Blood or urine test results confirming the presence of drugs

Updated Penalties for a Drug DUI in New Jersey

Driving under the influence of drugs (DUI) in New Jersey is treated just as seriously as alcohol-related DUI offenses. However, unlike alcohol DUIs, which rely on Blood Alcohol Concentration (BAC) levels, drug DUIs are determined based on observed impairment and toxicology reports. New Jersey has recently updated its penalties for drug DUIs, making it crucial for drivers to understand the legal consequences.

First Offense

Fines: $300–$500
Jail Time: Up to 30 days
License Suspension: 7 months to 1 year
Intoxicated Driver Resource Center (IDRC): 12–48 hours

Second Offense

Fines: $500–$1,000
Jail Time: 48 hours to 90 days
License Suspension: 1–2 years
Community Service: 30 days
IDRC: 48 hours
IID: Required for 2–4 years after license restoration

Third or Subsequent Offense

Fine: $1,000
Jail Time: 180 days
License Suspension: 8 years
IDRC: As determined
IID: Required for 2–4 years after license restoration

Key Differences Between Alcohol and Drug DUIs in New Jersey

There are three key differences between a DUI for Alcohol and a DUI for Drugs in the state of New Jersey.

Testing and Evidence – Alcohol DUI cases rely primarily on breathalyzer tests, while drug DUIs depend on officer observations, DRE evaluations, and chemical tests.
Ignition Interlock Devices – Unlike alcohol DUIs, drug DUI offenders are not required to install an IID unless it is a second or subsequent offense.
License Suspensions – Unlike updated alcohol DUI laws that emphasize IIDs over suspensions, drug DUIs still carry mandatory license suspensions.

Defending Against a Drug DUI Charge

A strong defense can challenge various aspects of a drug DUI charge, including:

The validity of the traffic stop
Accuracy of DRE assessments
Reliability of chemical test results
Potential violations of constitutional rights during the arrest

Drug DUIs are inherently more difficult for the State to prove. Although the penalties can be more severe, the defenses are stronger.

How New Jersey Handles DUI Charges for Residents Arrested Out of State

New Jersey residents who receive a DUI charge in another state may face consequences not only in the state where the offense occurred but also upon returning to New Jersey. The state’s handling of out-of-state DUI convictions is governed by the Interstate Driver’s License Compact (IDLC) and New Jersey state laws, which can result in additional penalties for New Jersey drivers.

Even if an out-of-state DUI does not result in a suspension in that state, New Jersey may still require the installation of an IID and other administrative penalties before reinstating driving privileges. Additionally, failure to comply with the penalties imposed by the MVC may result in further restrictions on a driver’s license.

The Interstate Driver’s License Compact (IDLC)

New Jersey is a member of the IDLC, an agreement among states to share information about serious traffic offenses, including DUI. If a New Jersey resident is convicted of a DUI in another state, that conviction will be reported to the New Jersey Motor Vehicle Commission (MVC), which may impose penalties similar to those for an in-state DUI offense. However, for New Jersey to take action on an out-of-state DUI conviction, the law under which the conviction occurred must be substantially similar to New Jersey’s DUI laws.

In order to determine “substantial similarity” New Jersey courts will review the out-of-state DUI statute to determine if it aligns with New Jersey’s DUI laws, particularly regarding:

The Blood Alcohol Concentration (BAC) threshold (0.08% in New Jersey)
Whether the out-of-state law requires proof of impairment or per se intoxication
The definition of operation of a vehicle under the law

If the out-of-state law is not substantially similar, New Jersey may not impose administrative penalties or treat the conviction as a prior offense in future DUI cases.

Fighting an Out-of-State DUI in New Jersey

New Jersey residents facing an out-of-state DUI conviction may have legal options to contest the penalties imposed by the MVC. An experienced DUI attorney can:

Challenge whether the out-of-state law is substantially similar to New Jersey’s law
Contest the reporting and application of penalties under the IDLC
Advocate for reduced penalties based on mitigating circumstances
Assist in resolving license suspension or IID requirements

Why You Need an Experienced DUI Defense Attorney

If you are facing DUI or refusal charges, the consequences can be severe. An experienced DUI defense attorney can:

Challenge the validity of the traffic stop and arrest
Question the accuracy of breathalyzer or field sobriety tests
Advocate for reduced penalties or alternative sentencing
