The bill amends R.S.39:4-50 to enhance the use of ignition interlock devices (IIDs) for individuals convicted of driving while intoxicated (DWI). It introduces provisions that allow individuals arrested for DWI to voluntarily install an IID in their vehicle before conviction, enabling them to request a special driver's license notation that permits operation of a vehicle equipped with the device. The bill specifies that those who install the IID and maintain a valid driver's license will not incur additional fines. It also establishes a credit system, allowing individuals to earn a one-day credit against their vehicle operation forfeiture period for every two days the IID is installed, although this credit is not available for violations resulting in serious bodily injury.

Furthermore, the bill allows individuals required to forfeit their right to operate a vehicle to opt for IID installation instead, with the same credit system applying, while excluding those convicted of operating a vehicle under the influence of narcotics from this credit. The bill also permits plea agreements under certain conditions, ensuring mandatory forfeiture of driving rights for a minimum of six months for specific serious offenses. The changes will take effect immediately for offenses occurring on or after the effective date, with an expiration set for January 1, 2029, aligning with related laws. Overall, the bill aims to provide a more flexible approach to managing DWI offenses while prioritizing public safety and accountability.
