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 DUI-related provisions. The bill requires any person convicted of driving under the influence or refusal to submit to a chemical test to have an ignition interlock system installed in their vehicle as part of any sentence before being eligible for license reinstatement. It outlines penalties for various DUI offenses, including fines, community service, imprisonment, and mandatory attendance at special courses.

The bill emphasizes the requirement for ignition interlock systems and blood and urine testing for convicted individuals, with specific timeframes for these restrictions based on the severity of the offense. Judges are mandated to prohibit offenders from operating vehicles not equipped with ignition interlock systems for defined periods, which can range from six months to ten years depending on the number of violations.

Additionally, the bill introduces a $100 assessment to the ignition interlock system fund for violations and establishes an "ignition interlock system fund" to assist indigent defendants who are required to comply with the provisions related to ignition interlock systems and who are unable to pay for the system. It also mandates that all ignition interlock systems must be equipped with a camera for driver identification. The act is set to take effect upon passage, reinforcing the state's commitment to enhancing road safety and reducing DUI incidents.
