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 new effective date of July 1, 2025, for the DUI provisions. The legislation establishes mandatory penalties based on blood alcohol concentration levels, including fines, community service, and imprisonment. It requires individuals convicted of DUI or refusal to submit to a chemical test to install ignition interlock systems in their vehicles for specified periods as a condition for license reinstatement. The bill specifies that the ignition interlock system must be equipped with a camera for driver identification, and it includes penalties for tampering with the camera.

Additionally, the bill establishes an "ignition interlock system fund" to assist indigent defendants who are required to comply with the ignition interlock provisions but are unable to afford the systems. The fund will be administered by the office of the general treasurer, which will designate a program administrator and promulgate necessary rules and regulations. The bill aims to enhance public safety by imposing stricter regulations and penalties for DUI offenses and promoting compliance across all financial situations.
