Lowell DUI Defense Attorney

Being arrested for a DUI can be an intimidating experience, and most drivers have many questions and concerns about the future.

A Lowell DUI Lawyer That can Handle any Case

  • First-time offenses: A first-offense OUI/DUI charge is a serious matter. First-time drunk driving charges in Massachusetts are far more than glorified traffic offenses. License suspension, mandatory programs, increase in insurance, significant penalties — these are just some of the consequences that can result from a first offense.
  • Repeat OUI/DUI offenses: A charge for an OUI second offense or more increases the potential for jail or prison time. In addition to longer license suspensions, required ignition interlock devices, inpatient treatment, and mandatory jail time, having a subsequent offense carries with it serious penalties that could even result in a felony conviction.
  • Loss of driving privileges: While significant fines and potential jail time are often concerns in OUI cases, the adverse impact on your privilege to drive is often a vital concern. From months long suspensions to lifetime revocation of your right to drive, the consequences for a DUI are severe in Massachusetts.
  • Breath test refusal in Massachusetts: Although your chances of success in your case may be better if you refuse to take a breath test, there are significant periods of license suspensions for refusal to take the test. Having a six month, three year, or greater license suspension can result in an incredible hardship. A skilled DUI lawyer can guide you through your options.
