What You Need to Know About DUI Charges in Massachusetts

It is against the law in Massachusetts to drive while under the influence of drugs or alcohol. According to Massachusetts General Laws Chapter 90, Section 24, a person can be charged with Operating Under the Influence (OUI)—commonly referred to as DUI—if their Blood Alcohol Content (BAC) is 0.08% or higher, or if their ability to drive is impaired by alcohol or drugs.

A first-time DUI charge may result in:

  • Fines and fees
  • A possible jail sentence
  • License suspension
  • Mandatory alcohol education programs

Repeat offenses or DUIs involving serious injuries can lead to enhanced penalties, including longer license suspensions, higher fines, and mandatory jail time.

How Our Criminal Defense Law Firm Builds Your DUI Defense

At the Law Office of Matthew W. Peterson, our approach is centered on detailed preparation, skilled negotiation, and aggressive courtroom representation. Our Massachusetts defense attorneys examine every aspect of your case, including:

Field Sobriety Tests

Officers often rely on Field Sobriety Tests to establish probable cause. These tests are subjective and often administered under poor conditions. We challenge the administration and interpretation of these tests when they are unreliable.

Breathalyzer Tests

If you submitted to a Breathalyzer Test, our team investigates whether the device was properly calibrated and maintained, and whether the officer was certified to administer it.

Blood Tests and Chemical Evidence

Chemical evidence must be collected, stored, and tested according to strict standards. If your blood test results were compromised or procedures were violated, we fight to suppress that evidence.

DUI Involving Serious Injury

If your DUI involved an accident that resulted in serious bodily injury, you may be facing enhanced charges. Under Massachusetts law, this can lead to felony charges, mandatory imprisonment, and long-term consequences. Our attorneys build a thorough defense strategy to contest causation, injury severity, and impairment allegations.
