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. It mandates the installation of ignition interlock systems for individuals convicted of DUI or refusal to submit to a chemical test as part of their sentence before being eligible for license reinstatement. The bill specifies compliance periods for the ignition interlock system based on the number of violations: six to twelve months for first-time offenders, twelve to forty-eight months for second violations, and twenty-four to one hundred twenty months for third or subsequent violations.

Additionally, the bill establishes a $100 assessment for the ignition interlock system fund, which will be administered by the office of the general treasurer to provide funding for indigent defendants required to comply with ignition interlock provisions but unable to pay for the system. It also includes a requirement for ignition interlock systems to be equipped with a camera to accurately identify the driver providing a breath sample.

The legislation emphasizes the importance of alcohol and drug education programs, requiring attendance for convicted individuals and allowing for clinical assessments to identify substance abuse issues. It outlines the conditions for reinstating driver's licenses for individuals with multiple DUI violations, mandating a hearing before a judicial officer. Furthermore, individuals convicted of serious DUI-related offenses resulting in death or serious injury may face a prohibition from operating a vehicle without an ignition interlock system for one to five years. Overall, the bill aims to enhance public safety by imposing stricter penalties and requirements for DUI offenders while ensuring support for those struggling with substance abuse.
