Massachusetts categorizes a DUI as an OUI (Operating Under the Influence) and a first offense can trigger severe penalties. Most drivers don't incur the maximum penalties but even the minimum assessment can cost thousands of dollars and require considerable time.
Unlike many states, Massachusetts has an unlimited look back period. That means that any previous OUI (Operating Under the Influence) charge will count as a prior offense. In addition, a law known as “Melanie’s Law” was enacted in 2005 to increase the penalties of Massachusetts’ OUI laws.
Massachusetts is one of the strictest states when it comes to enforcement of DUIs -- also known as “OUIs” (Operating Under the “Influence”). Read more on Massachusetts' third OUI penalties, look back period, and options.
Sobriety checkpoints are legal in Massachusetts (see 521 N.E.2d 987 (Mass. 1988)). These checkpoints (also referred to as "mobile checkpoints" or "roadblocks") are police traffic stops that are not tied to any specific or individual suspicions.
