DUI / OUI Defense

An open OUI/DUI charge can have a serious impact on your life. Your license may be suspended immediately, with the possibility of further suspension if convicted. If you have prior OUI/DUI convictions, the penalties become more severe, including the possibility of jail time. Let our office work to limit this impact.

What may matter in your case

  • The stated reason for the traffic stop
  • Field-sobriety instructions and administration
  • Breath, blood, or urine testing procedures
  • Calibration, maintenance, and operator records 
  • Body-worn camera, cruiser-camera, and dispatch evidence
  • Administrative license deadlines and related consequences

A focused defense starts early

Let us help you file pretrial motions to dismiss, suppress evidence obtained through an illegal search, or exclude evidence because of improper police conduct.

At trial, we can fight the prosecution’s case by showing that: (1) you were not driving; (2) you were not driving on a public way; or (3) you were not under the influence.

Whether you participated in field sobriety tests, breath tests, blood tests, or a combination of the three, the I can provide a vigorous defense and challenge each aspect of the Commonwealth’s case.

Facing a charge or investigation?

Speak with counsel before answering questions or making decisions that may affect your case. An attorney can help advise on what, if anything, you should say. Let someone from the Law Offices of Ryan P. Callahan guide you through this complicated process.
