An Act to protect the citizens of the Commonwealth from drunk drivers

This bill amends Chapter 90 of the Massachusetts General Laws to update and clarify the definitions used in operating under the influence cases. It directly affects drivers, law enforcement, and the courts by standardizing terms such as blood alcohol content, ignition interlock devices, and prior offenses. The legislation ensures that these specific legal concepts are clearly defined to include substances like marijuana and glue vapors, as well as precise criteria for what constitutes being under the influence. By refining these definitions, the bill aims to improve consistency in how drunk driving and substance-impaired driving incidents are processed and adjudicated.
