Experienced DWI/DUI Defense in New Hampshire and Massachusetts
Facing a DWI charge in New Hampshire or a DUI/OUI charge in Massachusetts can have serious consequences, including potential impacts on your driver's license, employment, insurance rates, finances, and personal life. These cases often involve both criminal proceedings and administrative license issues, making experienced legal guidance essential from the beginning.
At MacDonald Law, PC, our DWI/DUI defense attorneys bring a unique perspective to these cases. Several members of our team have backgrounds in law enforcement and prosecution, providing valuable insight into how impaired driving investigations are conducted, how evidence is collected, and how prosecutors evaluate these cases.
DWI and DUI cases can involve complex issues, including traffic stops, field sobriety testing, breath or blood testing, license suspensions, and challenges to the evidence used against you. In Massachusetts, impaired driving charges are commonly referred to as Operating Under the Influence (OUI) or Operating While Intoxicated (OUI), and these cases may involve both court proceedings and action through the Registry of Motor Vehicles (RMV).
Our team combines real-world experience, courtroom knowledge, and strategic advocacy to help clients understand their options and build a defense tailored to the specific circumstances of their case. Whether you are facing a first offense or more serious impaired driving allegations, MacDonald Law, PC is prepared to advocate for your rights.

Understanding the DWI Process
A DWI charge involves more than simply appearing in court. Depending on the circumstances, a person facing a DWI charge may need to address both:
Criminal Proceedings
A DWI charge can involve court proceedings where the prosecution must prove the allegations beyond a reasonable doubt.
Our attorneys carefully review the circumstances surrounding an arrest, including:
- The reason for the traffic stop
- Officer observations
- Field sobriety testing
- Chemical testing procedures

Administrative License Suspension
A DWI arrest may also involve a separate administrative process through the New Hampshire Division of Motor Vehicles.
