The bill amends R.S.39:4-50 in New Jersey, which governs penalties for driving while intoxicated. It establishes a tiered penalty system based on blood alcohol concentration (BAC) for first offenses, with fines ranging from $250 to $500, mandatory detainment, and the installation of an ignition interlock device. Additionally, individuals arrested for these offenses may voluntarily install the device before conviction, potentially reducing certain fines if they maintain a valid driver's license. For subsequent offenses, the bill imposes increased fines, mandatory community service, and minimum imprisonment terms, while also clarifying that prior convictions from other jurisdictions will be recognized in New Jersey.

The bill further addresses the treatment of individuals under 17 years old convicted of intoxicated driving offenses, mandating immediate suspension of driving privileges until their 17th birthday, along with court-determined additional periods. It requires screening and participation in substance use disorder programs, with penalties for non-compliance, including imprisonment and continued license suspension. The legislation also introduces a supervised visitation program for offenders under 21 to witness the consequences of drunk driving, and imposes a $125 surcharge on convicted individuals, with funds allocated to municipalities and state programs. The act is effective immediately for offenses occurring on or after the effective date and will expire on January 1, 2029.
