DUI in New Jersey
State-specific overview · Criminal Law
New Jersey imposes a mandatory Ignition Interlock Device (IID) on all DUI convictions, even first offenses, with no exceptions.
How New Jersey treats DUI
New Jersey defines DUI at a BAC of 0.08% or higher and requires IID installation for a minimum of three months on first conviction, six months on second, and one year on third or subsequent offenses. First offenders face 12 to 48 hours in jail and a $250 to $400 fine, with license suspension of three months. A second offense within ten years escalates to 48 hours to 30 days jail time and two-year license suspension. New Jersey also enforces strict penalties for refusal to submit to breathalyzer testing, treating refusal similarly to conviction.
The general definition of DUI
Driving under the influence of alcohol or drugs, a serious criminal offense.
DUI stands for Driving Under the Influence and means operating a vehicle while impaired by alcohol, drugs, or both. You can be charged with DUI even if your blood alcohol level is below the legal limit if your driving is noticeably impaired. Penalties vary by jurisdiction and whether it's a first or repeat offense, but typically include fines, license suspension, jail time, and mandatory alcohol education programs. A DUI conviction has lasting effects on insurance rates, employment, and your driving record.
