The bill amends Chapter 31-27 of the General Laws, focusing on motor vehicle offenses related to driving under the influence (DUI) of alcohol or drugs. A key insertion is the establishment of a new effective date of July 1, 2025, for the DUI provisions. The bill outlines penalties based on blood alcohol concentration levels, including mandatory fines, community service, imprisonment, and license suspensions. It requires individuals convicted of DUI to install ignition interlock systems in their vehicles for specified durations, which vary depending on the severity of the offense.

Stricter penalties for repeat offenders are introduced, along with a focus on treatment programs for servicemembers, veterans, and juveniles. The bill mandates that individuals charged with a third or subsequent DUI violation undergo a hearing before license reinstatement. It establishes a highway safety assessment fee and a fee to support chemical testing programs. The bill also requires blood and urine testing for those with DUI offenses and clarifies conditions for conditional hardship licenses.

New requirements for ignition interlock systems include the installation of cameras for driver identification and penalties for tampering with the devices. An "Ignition Interlock System Fund" is created to support these initiatives, with all offenders contributing to the fund. The act is set to take effect upon passage.
