New Jersey Breathalyzer Challenge Lawyer

A breath reading of .08% or higher is enough to support a DWI conviction in New Jersey, even if you drove normally and showed no signs of impairment. That makes the number on the printout the center of many cases, and it is a number that can be tested. Drivers in Monmouth County, Ocean County, and Middlesex County who were arrested after a breath test have more room to contest it than most assume. Sanvenero & Cittadino, LLC is a New Jersey law firm that handles DWI and DUI defense, traffic tickets, and municipal and Superior Court criminal matters for clients throughout Monmouth, Ocean, and Middlesex Counties and across the state.

A New Jersey breathalyzer challenge lawyer looks past the result and asks how it was produced. Was the officer qualified to run the instrument? Was the machine in proper working order on the night of your arrest? Was the observation period before the test actually observed? Was the stop itself lawful? Each of those questions can affect whether the reading is admitted, how much weight it carries, and whether the State can prove a per se violation at all.

What Makes a Breath Test Result Vulnerable

A breath machine does not measure alcohol in your blood. It samples air from your lungs and applies a formula to estimate blood alcohol concentration. That estimate depends on several things going right at once: a calibrated instrument, a trained operator, a clean sample, and a subject who did nothing in the preceding minutes to contaminate the result. When any link fails, the figure may not be reliable.

The defense work usually starts with the paper trail. Maintenance and calibration records, the operator’s certification, the test ticket, and the arrest and stop reports all get compared against one another. Inconsistencies in time stamps, gaps in the required observation period, or a machine with a questionable service history can undercut a reading that looked airtight at the station. Because the State carries the burden of proving a per se violation based on that reading, a result that cannot be shown to be reliable may not support a conviction.

The firm’s criminal defense attorneys represent clients in municipal courts and Superior Court on DWI and DUI charges, including breath test refusals, drug DWI, and repeat offenses, and they also handle the traffic tickets that can accompany an arrest and the license consequences that follow.

Joshua Cittadino, Founding Partner, brings courtroom experience across real estate, construction litigation, personal injury, employment matters, and business transactions, and that litigation background carries into contested hearings where evidence has to be tested rather than accepted. Richard Sanvenero, Managing Partner, is a New Jersey Supreme Court Certified Matrimonial Attorney and former Family Part law clerk, which matters for clients whose DWI arrest also touches a pending divorce, custody dispute, or support obligation. Mike Canarick, Of Counsel, practices in tax and estate planning. Our attorneys are admitted in New Jersey, New York, Florida, and the District of Columbia, and several have been recognized by Super Lawyers.

The firm has recovered $400,000 for personal injury clients in just three months, and it brings that same preparation to defense work. Clients can expect a team that communicates clearly, returns calls, and explains each step in plain terms. Because a DWI rarely stays in one lane, with employment, licensing, family court, and finances often affected together, the firm’s coordinated team across family, business, real estate, estate planning, and litigation practices gives clients one place to address all of it.

Common Grounds for Challenging a Breath Reading

• Unlawful Traffic Stop: If the officer lacked a legitimate reason to pull you over, the evidence that follows, including the breath test, may be suppressed. Stops based on a hunch, an inaccurate description of driving behavior, or a violation that the video does not support are common targets.
• Improper Observation Period: The operator is expected to watch the subject for a set period before testing to make sure nothing is swallowed, regurgitated, or placed in the mouth. If the officer was filling out paperwork, handling another driver, or out of the room, the reading’s reliability is open to question.
• Operator Certification and Training: Only a trained and currently certified operator should run the instrument. Lapsed credentials or mistakes in how the test was administered can undermine the result.
• Calibration and Maintenance Records: The machine must be checked and maintained on a regular schedule. Missing or irregular records, or a record of repeated problems with a unit, can cast doubt on any reading it produced.
• Mouth Alcohol and Medical Conditions: Acid reflux, recent dental work, certain diets, and even some oral products can introduce alcohol into the breath sample and distort the figure.
• Rising Blood Alcohol: Alcohol takes time to absorb. A driver who drank shortly before the stop may have been below .08% while driving and above it by the time the test was given at the station.
• Test Refusal Charges: A refusal is its own offense, and the State must show the request was properly made and the driver was properly informed. A first refusal carries a license suspension of 7 to 12 months, a fine of $300 to $500, and attendance at the Intoxicated Driver Resource Center.
• Lower Thresholds for Special Drivers: A commercial driver can be charged at .04%, and a driver under 21 can face penalties for any reading of .01% or higher but below .08%, so the margin for error is much smaller.

What to Do After a Breath Test Arrest in Monmouth, Ocean, or Middlesex County

Start by writing down everything you remember while it is fresh: where you were stopped, what the officer said about the reason for the stop, how long you waited before the test, what you ate and drank and when, and whether anyone else was present at the station. Memory fades fast, and the timing of drinks and the sequence at the station often matter more than clients expect. Save receipts, tab records, and the names of anyone who saw you that evening.

Next, move quickly on representation. DWI matters are usually heard in the municipal court of the town where the stop occurred. For example, Red Bank Municipal Court also handles Shrewsbury Township matters, Holmdel and Colts Neck share court sessions held in Colts Neck, Eatontown matters are now handled by Tinton Falls Municipal Court, and Toms River, Long Branch, Asbury Park, Middletown, Rumson, and both Freehold municipalities each have their own courts. Your first appearance will be there, and early defense work often includes demanding discovery, which should include the stop report, video, test records, and maintenance and operator documentation. Aggravated cases can be elevated to Superior Court, which sits at the Monmouth County Courthouse in Freehold and the Ocean County Courthouse in Toms River.

Be careful about what you say and sign. Do not discuss the case on social media, and do not contact the arresting officer or court staff to argue the facts. Mistakes people make include assuming a first offense can simply be pleaded to quickly, missing a court date, and not realizing that the license consequences and the court case run on separate tracks. A first offense at .08% to under .10% carries a fine of $250 to $400, up to 30 days in jail, an Intoxicated Driver Resource Center program of 12 to 48 hours, and an ignition interlock for 3 months. At .10% or above, or with drug impairment, the first-offense fine rises to $300 to $500. A second offense brings a fine of $500 to $1,000, up to 90 days in jail, 30 days of community service, and an ignition interlock. A third or later offense brings a $1,000 fine and at least 180 days in county jail or a workhouse, with up to 90 days creditable for time in an approved inpatient rehabilitation facility. A first offense within 1,000 feet of a school or school crossing carries a fine of $600 to $1,000.

Breath Testing Versus Refusal: Weighing the Tradeoffs

Drivers often ask whether refusing the breath test would have been smarter. The law makes that a hard bet. A refusal is a separate violation with its own penalties, and a second refusal carries a two-year license suspension while a third carries ten years. Refusal also does not necessarily end the prosecution if the State has other evidence of impairment, such as driving behavior, field sobriety observations, or admissions.

On the other side, taking the test creates a number that becomes the State’s main exhibit. That is why the reliability of the number matters so much to the defense. If you refused, the fight shifts to whether the officer followed the required procedure in making the request and explaining the consequences. If you submitted, the fight shifts to the instrument, the operator, and the circumstances. Either path benefits from early review of the records, and the right approach depends on the specific facts of your stop and arrest.

Questions About Challenging a Breath Test in New Jersey

Can I be convicted of DWI if my breath test result is thrown out?

Yes, though it becomes harder. New Jersey recognizes a per se violation based on the reading and also a violation based on observed impairment. If the reading is excluded or discredited, the State would have to prove impairment through driving behavior, observations, and other evidence.

What does a .08% reading actually mean legally?

A reading at or above .08% allows the State to charge a per se violation without proving you were visibly impaired. The prosecution still has to prove the reading is valid and reliable, which is where challenges to the machine and the procedure come in.

How do I find out whether the breath machine was working properly?

Your attorney can demand discovery that includes maintenance, calibration, and operator certification records for the instrument and the officer. Comparing those records to the date and time of your test often shows whether the machine was in proper working order.

What is the observation period and why does it matter?

Before the test, the operator must watch the subject for a set period to confirm nothing enters the mouth that could contaminate the sample. If the officer was distracted or absent, the reading’s reliability can be challenged.

Can a medical condition like acid reflux affect the result?

It can. Conditions that bring stomach contents into the mouth, as well as recent dental work, can introduce mouth alcohol and inflate the reading. Medical documentation can support this argument.

Is it worth hiring a lawyer for a first-offense DWI?

A first offense can still bring fines, an IDRC program, an ignition interlock, and license consequences, and a conviction stays on your driving record. Because breath test defenses depend on reviewing records and procedures, early involvement of counsel gives you more options.

What happens if I refused the breath test?

A refusal is charged separately from DWI. A first refusal carries a license suspension of 7 to 12 months, a fine of $300 to $500, and IDRC attendance. A second refusal brings two years, and a third brings ten. The State must show that the request and warnings were properly given.

Do commercial drivers face a lower limit?

Yes. A reading of .04% or higher while operating a commercial vehicle is sufficient for a DWI charge, which makes accuracy of the test and the circumstances of the stop especially important for professional drivers.

How does a DWI affect drivers under 21?

A driver under 21 with a reading of .01% or higher but less than .08% faces a license suspension of 30 to 90 days, 15 to 30 days of community service, and mandatory IDRC participation. Even a small reading can matter, so the reliability of the test is critical.

Can a DWI arrest affect a divorce or custody case?

It can. Alcohol-related allegations may come up in custody and parenting time disputes, and under the current custody statute child safety is the threshold issue judges consider. Our firm’s family law attorneys can coordinate with the defense team so the two matters are handled consistently.

How long does a municipal court DWI case take?

Timing varies by court, by how much discovery is disputed, and by whether motions are filed. Cases that involve contested breath test records or suppression motions typically take longer than those resolved early.
