Westfield DWI Lawyer

Reviewed by William A. Proetta, Esq. · Updated November 2026

Westfield Municipal Court received 60 DWI filings over the July 2025 to June 2026 reporting period, up from 46 the year before, a rise of about 30% in a year when the court’s overall criminal and traffic filings dipped slightly. Many of those cases start near a downtown with more than 40 restaurants, along Route 28 (South Avenue and North Avenue) beside the Raritan Valley Line tracks, or on the town’s busy cross streets. Westfield’s court sits at 425 East Broad Street, in the same building as police headquarters. See our Westfield Municipal Court guide for how the court operates, and our Union County drunk-driving defense page for the wider picture.

Westfield DWI: Key Facts

• Court: Westfield Municipal Court, 425 East Broad Street (court code 2020). Court is held on Tuesdays and Thursdays, and anyone pleading not guilty or appearing virtually must first file the court’s Virtual Municipal Court Registration Form.
• Charges: N.J.S.A. 39:4-50 covers driving while intoxicated; N.J.S.A. 39:4-50.4a covers refusing to provide breath samples.
• DWI up, everything else flat: 46 filings became 60, about 30% more, while total non-parking filings slipped about 1%, from 3,095 to 3,059.
• Tenth in the county by count: 60 DWI filings ranked 10th of Union County’s 21 municipal courts, but Westfield’s larger population puts its rate at about 19.3 per 10,000 residents, 17th of 21.
• First offense, BAC 0.10% to just under 0.15%: $300–$500 fine, jail of up to 30 days, and an ignition interlock for 7 months to 1 year.
• Plea bargaining: no longer prohibited for DWI since 2024, yet offers remain the exception.

Many Westfield arrests begin on town streets rather than a highway. Local police blotters have described DWI arrests after stops on Mountain Avenue near Walnut Street and at East South Avenue and Sussex Street, after a one-car crash on the 500 block of Springfield Avenue, and after a call about an erratic driver near West South Avenue. Each of those starting points raises different legal questions. William A. Proetta brings two credentials to them: Draeger’s own certification on the Alcotest 9510, and recognition as an SFST instructor who teaches Standardized Field Sobriety Testing to NHTSA standards. He applies that training to the officer’s reports and recordings, and when you call, the conversation is with him.

Westfield’s court page sets one procedural rule that matters right away in a DWI case: to plead not guilty, or to take part virtually, a defendant or attorney must first submit the Virtual Municipal Court Registration Form. The page still carries pandemic-era wording describing in-person sessions as suspended and Zoom hearings in their place, so read your notice for the format of each listing. Recording the proceedings is prohibited. Sessions run on Tuesdays and Thursdays, giving Westfield two court days a week. Because the court shares 425 East Broad Street with the police department, the arresting officers work in the same building where the case is heard. Under the Town Code, the municipal prosecutor and public defender are each appointed for one-year terms, and an applicant for the public defender pays a $200 fee that the court can waive in whole or in part.

What Westfield’s DWI Filings Show

Westfield went from 46 to 60 DWI filings, fourteen more cases, while the rest of the court’s non-parking docket held almost steady. By count, Westfield was 10th of Union County’s 21 municipal courts.

Population changes the picture. With 31,032 residents, one of the county’s larger populations, Westfield’s rate is about 19.3 DWI filings per 10,000 residents, 17th of 21 and under the countywide rate of roughly 30. Neighboring Mountainside filed fewer cases (25) but, with about 7,000 residents, posted a much higher rate of 35.6. A town with a large residential base and a busy restaurant district can produce a meaningful count and still a modest rate.

Keep the limits of these figures in mind. They are court filings, not convictions, and one driver can account for more than one filing. They don’t identify the arresting agency or the street, and a year-over-year increase of fourteen cases doesn’t tell you whether your own case’s evidence would survive a challenge.

The 2020 Census supplies the population (31,032) and land area (6.72 square miles); the 63 sworn officers are the 2025 FBI figure listed on PoliceCensus. Dividing filings by population lets towns of different sizes be compared, but it isn’t the fraction of Westfield residents who were charged. A department of about sixty officers, with a dedicated traffic safety division, can put more than one car on a DWI call, which can mean several body-worn camera recordings and supplemental reports. We want all of them, not just the arresting officer’s.

Inside town, Westfield police patrol Route 28 and the local streets, so for stops inside town the usual arresting agency is the town’s own department. The highways are on the edges. U.S. Route 22 runs along the northern boundary, and much of the adjacent mainline lies in Mountainside and Scotch Plains, so the precise stop location determines the court. Garden State Parkway Exits 135 and 137 serve Westfield, but the interchanges are in Clark and Cranford, and Parkway arrests by the State Police near those exits are usually filed in one of those courts instead. We establish the observation point and the stop location, then request the matching agency’s video, CAD and dispatch records, and Alcotest data.

Reviewing the Evidence in a Westfield DWI Case

Our review takes the encounter apart one decision at a time: why the officer stopped or approached you, what justified a sobriety investigation, and whether probable cause existed when the arrest was made. For crash and tip cases, there is an earlier question too: what evidence shows when you were driving and in what condition.

Roadside observations and field sobriety tests

Downtown stops in Westfield usually end on lit streets, but curbs, crowned roadways, parked cars and passing pedestrians can all affect balance tests. After a crash, an officer may be testing someone who is shaken, injured or affected by an airbag deployment. NHTSA’s standardized tests (horizontal gaze nystagmus, the one-leg stand and the walk-and-turn) are only as good as the instructions, demonstration and scoring behind them. Mr. Proetta reviews the video against the manual, clue by clue. Read more on challenging field sobriety tests.

A driver who declines the roadside tests hasn’t thereby given police probable cause, but the officer can still make an arrest based on everything else observed.

Breath-test records and the testing timeline

New Jersey’s Supreme Court upheld the Alcotest in State v. Chun (2008) subject to firm safeguards, chief among them a 20-minute observation period before any sample, to keep mouth alcohol from inflating the number. In a crash case, the timing question is larger: how long passed between the driving and the test, and what happened in between. We confirm from the records where the test was given and who operated the instrument, then examine the operator’s certification, the calibration and maintenance logs, the observation interval and the video time stamps. See our Alcotest 9510 page.

Refusal allegations

A refusal count under N.J.S.A. 39:4-50.4a is tried on its own facts. We examine whether probable cause existed for the breath-test request, whether the standard statement was delivered accurately and completely, how you responded, and what the instrument logged about your attempts. First-time refusal carries $300–$500 in fines, no driving privileges until the interlock goes in, then 9 to 15 more months with it, even if the DWI is not proven.

New Jersey DWI Penalties

Beyond the table, any conviction requires the IDRC program and Motor Vehicle Commission surcharges of $1,000 each year for three years (first or second offense) or $1,500 each year for three years (third offense). The 2025 law known as P.L.2025, c.41 gives drivers facing suspension the option of driving with an interlock, credited at one suspension day for every two days the device is in use. It does not cover drug DWIs or cases involving serious bodily injury.

Can a Westfield DWI Case Be Resolved Through a Plea Agreement?

There is no longer a legal bar. New Jersey’s Legislature authorized DWI plea agreements; Guideline 4, the old prohibition, came off the books when the Supreme Court withdrew it in February 2024. Day to day, though, DWI plea offers are scarce, and a Westfield defendant should treat one as a possibility, not an expectation.

A plea still needs a factual basis and judicial approval, and it has to beat the outcome the evidence realistically supports. Our work starts there. A stop without a valid reason, a crash case with no clear timeline, field tests given off-protocol, or gaps in the Alcotest records are what lead to dismissals, excluded readings or a negotiated result.

Preparing for Your Westfield Court Appearance

• Submit the registration form first. Westfield requires the Virtual Municipal Court Registration Form before you can plead not guilty or appear virtually; your lawyer can file it for you.
• Know your day. Westfield sits on Tuesdays and Thursdays. Check which one your notice lists and whether the listing is virtual or in person.
• Don’t record the hearing. The court prohibits recording of its proceedings, including virtual ones.
• Reconstruct your evening while it’s fresh: where you ate or drank, when you left, your route through town and where the officer first appeared.
• If there was a crash, keep photos, insurance correspondence and any medical records from that night.
• Weigh the public defender option early. The application carries a $200 fee, which the court can waive, so decide on representation before your first listing.
