How Strong Is Your Defense? 

Client Reviews

Building Your Defense 

The Stop

All DUI/OUI defenses start with how and why you were stopped by the police. Our DUI/OUI law firm will uncover every detail, as a minor detail can make all the difference.

If the police did not have a 'reasonable and articulable' basis for stopping you, any evidence gathered must be suppressed, and the police will not have a case.

The Field Sobriety Test 

Our DUI/OUI defense lawyers will investigate how your field sobriety tests were administered. Strict procedures must be followed and many DUI/OUI cases are dropped based on how these tests were conducted.

Based on our experience and knowledge of DUI/OUI law, our law firm will let you know how strong of a factor your field sobriety test plays in your defense.

The Breathalyzer & Blood Testing

One of the most complex aspects of a DUI/OUI case involves evaluating breath and blood tests. There are a wide range of factors that can influence both the admissibility and accuracy of a breath or a blood test. In many instances, the outcome of this evaluation will have a major impact on the strength of your defense.

If you have been charged with DUI/OUI you need lawyers that are experienced in interpreting the nuances of breath and blood testing. Don't risk your defense to an inexperienced lawyer, call us today.
