Massachusetts DUI / OUI Defense Attorney

In Massachusetts, a charge of Operating Under the Influence (OUI) — also known as DUI — is one of the most serious traffic offenses you can face. A conviction can result in license suspension, heavy fines, jail time, mandatory programs, and a permanent criminal record that can affect your employment, insurance rates, and personal life for years.

What is OUI in Massachusetts?

Massachusetts law (G.L. c. 90, § 24) makes it illegal to operate a motor vehicle while under the influence of alcohol or drugs, or with a blood alcohol content (BAC) of 0.08% or higher. Commercial drivers face a lower threshold of 0.04%. There are also enhanced penalties for drivers under 21.
