These figures are DWI case filings reported for Piscataway Municipal Court. They are not a count of police arrests, convictions or stops on any particular road.

Piscataway’s DWI statistics illustrate a high volume of drunk-driving cases handled by its municipal court. Unlike many neighboring municipalities, Piscataway has three agencies conducting DWI investigations: the Piscataway Police Department, Rutgers University Police Department and New Jersey State Police on Interstate 287. With two major Rutgers campuses, heavily traveled local roadways and a major interstate highway, there is a constant source of DWI enforcement activity. However, the number of DWI cases above, does not necessarily reflect the total DUI convictions in Piscataway. For anyone charged with DWI in Piscataway, these statistics provide useful local context, but the outcome of an individual case ultimately depends on the evidence and circumstances surrounding the arrest.

Major Highways and Roadways in Piscataway for DWI Stops
Local driving routes and traffic areas; not a ranking of DWI arrest locations.
Interstate 287
Interstate 287 passes through Piscataway and provides regional connections for commuters, business travelers and motorists accessing nearby industrial and commercial areas. Highway ramps and merging traffic create different observation and stopping conditions from local streets such as Stelton Road. For a DWI arrest beginning on I-287, the location of the initial stop, arresting agency and where police later conducted testing should be verified from discovery.
Stelton Road
Stelton Road is a principal commercial corridor through Piscataway, connecting shops, neighborhoods and roadways leading toward South Plainfield. The intersections with New Brunswick Avenue and Old New Brunswick Road are identifiable local traffic points. If a stop begins with a turning or lane-use allegation, traffic signals, business entrances and available recordings may help evaluate the officer's account.
River Road
River Road follows the Raritan River corridor near Rutgers-area destinations and connects Piscataway with neighboring Highland Park. Unlike the township's broad commercial roads, sections of River Road have distinct curves, intersections and residential access. In a DWI investigation, the actual lane configuration, lighting and stop location may be relevant to both the driving allegation and any roadside sobriety testing.
Centennial Avenue
Centennial Avenue is an important approach to Piscataway's office, industrial and business-park areas, with connections to major regional roads. Commuter peaks and vehicles entering employment properties can alter traffic conditions throughout the day. If police initiate a DWI stop in this corridor, the specific intersection or entrance, the officer's initial observations and any recorded evidence warrant close review.
Three Police Agencies That Make DWI Arrests in Piscataway
One of the distinguishing features of DWI enforcement in Piscataway is the presence of three police agencies with overlapping jurisdiction in the township. In addition to the local police department, Rutgers University operates its own police force on its campuses, while the New Jersey State Police patrol Interstate 287.
The agency responsible for your arrest can affect the reports, recordings and other evidence that must be obtained and reviewed when preparing your defense.
1. Piscataway Police Department
The Piscataway Police Department conducts DWI enforcement throughout the township, including busy local roadways such as Stelton Road, River Road, Centennial Avenue, Hoes Lane and Easton Avenue.
Officers may initiate drunk-driving investigations after observing a traffic violation, responding to a motor vehicle accident or receiving a report of suspected impaired driving. The circumstances leading to the initial police encounter can be important in determining whether the stop and subsequent investigation were lawful.
2. Rutgers University Police Department
Piscataway is home to Rutgers University’s Busch and Livingston campuses. Rutgers University Police Department officers patrol university facilities, parking areas and campus roadways, where they may investigate suspected impaired driving.
DWI arrests involving Rutgers Police may occur near student residences, university parking lots, athletic facilities or roads connecting the university’s campuses. These cases are not limited to Rutgers students; university employees, visitors and other motorists may also encounter campus police.
A Rutgers Police DWI arrest occurring in Piscataway is generally handled in Piscataway Municipal Court, rather than through the university’s disciplinary system alone.
3. New Jersey State Police – Interstate 287
Interstate 287 runs through Piscataway and is patrolled by the New Jersey State Police. State troopers conduct traffic enforcement and DWI investigations on this major highway, including the exits connecting I-287 to River Road, Centennial Avenue and other Piscataway roadways.
A driver stopped by a state trooper on I-287 within Piscataway may receive a summons requiring an appearance in Piscataway Municipal Court. The location of the alleged offense, rather than the police agency making the arrest, generally determines which municipal court handles the matter.
The penalties for a New Jersey DWI conviction depend on several factors, including the driver’s blood alcohol concentration, whether the offense involves alcohol or drugs, and any prior DWI convictions.
Under N.J.S.A. 39:4-50, penalties can include fines, driver’s license forfeiture or suspension, mandatory participation in the Intoxicated Driver Resource Center, ignition interlock requirements and imprisonment.
Defending DWI Charges in Piscataway
A DWI arrest does not automatically mean that the prosecution has sufficient evidence to obtain a conviction. Our attorneys examine the circumstances of the stop, the officer’s observations, the administration of field sobriety tests, breath-testing procedures and any available video recordings.
The specific issues that arise in a case often depend on how the investigation began and which police agency conducted the arrest.
Challenging the Initial Traffic Stop
Police officers generally must have a lawful basis for stopping a vehicle. A DWI investigation may begin with an alleged traffic violation, erratic driving, an accident or another encounter with law enforcement.
Our attorneys review police reports, dashcam footage, body-worn camera recordings and other available evidence to determine whether the initial stop was constitutionally permissible. If the police violated a driver’s rights, it may be possible to seek suppression of evidence obtained during the unlawful encounter.
Challenging Field Sobriety Tests
Police officers frequently rely on standardized field sobriety tests when deciding whether to arrest a motorist for suspected drunk driving. These tests may include the Horizontal Gaze Nystagmus, Walk-and-Turn and One-Leg Stand tests.
However, the reliability of field sobriety testing can be affected by improper instructions, uneven pavement, poor lighting, weather conditions, physical limitations and an officer’s failure to follow standardized procedures.
Attorney William Proetta is certified in Standardized Field Sobriety Testing. This training can be particularly useful when evaluating whether the arresting officer properly administered and interpreted the tests.

Challenging Alcotest Breath Test Results
Many New Jersey DWI prosecutions rely on breath-testing evidence obtained using the Alcotest. However, breath test results are admissible only when the State establishes the applicable legal and scientific requirements. In fact, our DWI defense attorneys are able to suppress the breath readings in the majority cases.
Our attorneys examine the Alcotest documentation, calibration records, operator qualifications and procedures followed before and during testing. We also evaluate whether the required observation period was properly conducted and whether any circumstances may have affected the reliability of the results.
William Proetta has received training and certification from Dräger in the operation and maintenance of the Alcotest 9510 and 7110.
Reviewing Police Body Camera and Dashcam Footage
Video recordings can be particularly important in DWI investigations conducted by the Piscataway Police Department, Rutgers University Police Department and New Jersey State Police.
Where available, MVR footage may show the driving behavior that preceded a traffic stop, the body cameras will show officer’s interaction with the motorist, the videos from police headquarters will show the administration of the Alcotest breathalyzer machine.
Comparing video evidence with an officer’s written reports may reveal inconsistencies or identify facts relevant to challenging the State’s case.
What Are the Penalties for DWI in Piscataway, NJ?
| Offense | Potential consequences |

These are general statutory penalties. The applicable ignition interlock period, driving restrictions, additional assessments and opportunities for statutory credits depend on the particular offense and circumstances.
Refusal to Submit to a Breath Test in Piscataway
A driver who refuses to submit to a legally requested evidential breath test can face a separate refusal charge under N.J.S.A. 39:4-50.4a.
A refusal charge may be prosecuted even if the driver is ultimately found not guilty of the underlying DWI offense. The State must establish the legally required elements of refusal, including probable cause for the DWI arrest and an actual refusal to submit to the requested test.
The consequences of a refusal conviction can include fines, ignition interlock requirements, IDRC participation and license forfeiture. Repeat refusal offenses carry additional penalties.
Our attorneys examine the officer’s observations, the circumstances of the arrest, the instructions given to the driver and any available recordings to determine whether the State can establish the refusal charge.
