The bill amends several sections of the General Laws in Chapter 31-27, 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 (BAC) and the presence of controlled substances, mandating fines and requiring the installation of ignition interlock systems for individuals convicted of DUI or refusal to submit to chemical tests as part of their sentence before being eligible for license reinstatement.

The bill specifies that judges must prohibit offenders from operating vehicles that are not equipped with ignition interlock systems for designated periods, which vary based on the severity of the offense and prior convictions. It also mandates that ignition interlock systems installed must be equipped with cameras to accurately identify the driver providing a breath sample.

Additionally, the bill establishes an "Ignition Interlock System Fund" to support the program, which will be administered by the office of the general treasurer. The office will designate a program administrator and promulgate necessary rules and regulations. The bill emphasizes the importance of chemical testing and modifies the language regarding judges' discretion in imposing penalties, making it mandatory for judges to enforce these requirements.

Overall, the bill aims to enhance public safety through stricter regulations and compliance measures for DUI offenders, including the establishment of a fund to support the ignition interlock system program.
