New Jersey DWI Law and Penalties
Driving While Intoxicated (DWI) in New Jersey is defined under N.J.S.A. 39:4-50. It is critical to understand that DWI is classified as a traffic offense, not a criminal charge. This means it is heard in Municipal Court, does not appear on a criminal record, and offers no right to a jury trial. However, the penalties remain severe and can have a major impact on your life.
