New Jersey DWI Law and Penalties
Last verified: April 2026 | Superior Court of NJ, Mercer Vicinage | New Jersey Legislature
Driving While Intoxicated (DWI) in New Jersey is defined under N.J.S.A. 39:4-50. Unlike many states, a DWI is classified as a traffic offense, not a criminal charge. This means it is heard in Municipal Court, not Superior Court, and does not create a criminal record. However, the penalties are severe and can have a major impact on your life and finances. The statute prohibits operating a motor vehicle with a blood alcohol concentration (BAC) of 0.08% or higher, or while under the influence of intoxicating liquor, narcotic, hallucinogenic, or habit-producing drug.

For the official text of the DWI statute, refer to N.J.S.A. 39:4-50 on the New Jersey Legislature website. For court-specific information, you can visit the Superior Court of New Jersey, Mercer Vicinage official website.
Handling a Mercer County DWI Case
In Mercer County, all DWI cases are processed through the Municipal Court located at 175 South Broad Street in Trenton. A key distinction in New Jersey is the extremely limited opportunity for plea bargaining; the state generally prohibits pleading a DWI down to a lesser charge. Defense often focuses on challenging the administration and calibration of the Alcotest breath test machine and ensuring law enforcement followed the required 20-minute observation period prior to testing.
- Receive your DWI summons and note your court date.
- Consult with a DWI defense lawyer to review the evidence, including police reports and breath test records.
- Your attorney may file pre-trial motions to challenge the stop, arrest, or breath test procedures.
- Attend your Municipal Court hearing, where your lawyer will present your defense.
- If convicted, comply with all court orders, which may include fines, IDRC attendance, and ignition interlock installation.
