South Brunswick’s extensive highway network creates a different enforcement environment from that of smaller Middlesex County municipalities. The township includes heavily traveled commercial corridors, residential roads and portions of major highways used by motorists traveling throughout Central New Jersey.
According to the New Jersey Judiciary’s Municipal Court Statistics for July 2025 through June 2026, South Brunswick Municipal Court recorded 77 DWI filings. These are court filings rather than a count of arrests made exclusively by the South Brunswick Police Department. Motorists arrested by other agencies within the township may also have matters heard in municipal court.

South Brunswick by the Numbers
Population, police staffing and municipal court DWI filings in context.
The township’s population, police staffing, land area and DWI filing rate help place its enforcement activity in context. The DWI filing rate is calculated using municipal court filings per 10,000 residents, not the number of township residents arrested for drunk driving.
Where Do DWI Arrests Occur in South Brunswick?
South Brunswick includes several major roads that carry local, commuter and commercial traffic. DWI investigations may arise from an observed moving violation, a motor vehicle accident, a report of erratic driving or other circumstances that give police a lawful basis to investigate.
The South Brunswick Police Department conducts local traffic enforcement, while New Jersey State Police have jurisdiction over the New Jersey Turnpike. The investigating agency and location of the stop can affect the evidence available in a particular case.
Major Highways and Roadways in South Brunswick for DWI Stops
Local driving routes and traffic areas; not a ranking of DWI arrest locations.
U.S. Route 1
Route 1 is a major north-south commuter and commercial corridor through South Brunswick, serving office developments, shopping destinations and connections to neighboring townships. Multi-lane traffic and vehicles entering or exiting commercial properties can complicate driving observations. A DWI investigation arising here may turn in part on the precise intersection or roadway segment, traffic signals and available video.
Route 27
Route 27 runs through the Kendall Park section of South Brunswick and connects the township with nearby North Brunswick and Franklin Township. Its commercial strips, residential intersections and steady local traffic distinguish it from the high-volume Route 1 corridor. If police initiate a DWI stop here, the alleged traffic violation and the roadside conditions at the specific location deserve individualized review.
Route 130
Route 130 serves the eastern side of South Brunswick and connects commercial, logistics and residential areas with neighboring Cranbury and North Brunswick. Heavy vehicles and through traffic may share the roadway with motorists making local turns. When a stop occurs near a business entrance or major intersection, lane configuration and traffic conditions can be important in assessing the officer's account.
New Jersey Turnpike & Route 32
Route 32 connects Route 130 with New Jersey Turnpike Exit 8A. The Turnpike itself is patrolled by New Jersey State Police, so a DWI case arising on this portion of the highway may begin with a state trooper rather than a South Brunswick police officer.
How Our Attorneys Defend South Brunswick DWI Charges
The outcome of a DWI case often depends on the lawfulness of the police investigation and the reliability of the evidence. Our attorneys examine the particular circumstances of each arrest rather than assuming that a positive breath test or an officer’s description of poor field sobriety performance establishes guilt.
Challenging Field Sobriety Tests
The Walk-and-Turn, One-Leg Stand and Horizontal Gaze Nystagmus tests are frequently used during roadside DWI investigations. Their significance depends on proper administration, the testing environment and the driver’s individual circumstances.
Uneven pavement, traffic, poor lighting, footwear and physical limitations may be relevant when evaluating an officer’s observations. We compare the police report with available video and examine whether the officer followed standardized testing procedures.

Challenging Alcotest Evidence
Breath test evidence must satisfy New Jersey’s applicable scientific and procedural requirements. Our attorneys review the Alcotest model used, operator qualifications, relevant calibration and maintenance records, observation procedures and the Alcohol Influence Report.
We also examine whether the available stationhouse video and police documentation are consistent with the reported testing procedure.

What Are the Penalties for DWI in South Brunswick?
South Brunswick DWI cases are prosecuted under N.J.S.A. 39:4-50, the same statute that governs drunk driving throughout New Jersey.
A conviction may result in fines, ignition interlock requirements, mandatory attendance at the Intoxicated Driver Resource Center and, depending on the offense, license suspension or imprisonment. Repeat offenses generally carry more substantial penalties.
A driver who refuses a legally requested evidential breath test can also face a separate charge under New Jersey’s implied-consent law.
