Charged With Drunk Driving in Brentwood? Take Immediate Action With Aggressive Legal Guidance

If you’ve been arrested or charged with a DUI (Driving Under the Influence) in Brentwood, New Hampshire, your next step is critical. DUI charges in New Hampshire carry serious legal consequences that can affect your driving privileges, employment, insurance rates, and your freedom. At the Law Office of Matthew W. Peterson, we have our relentless DUI defense attorney in Brentwood focus on aggressive criminal defense strategies and a results-driven approach. Our team includes former prosecutors and experienced trial lawyers who understand how DUI cases are handled by the courts and law enforcement.

New Hampshire law under RSA 265-A outlines a variety of offenses related to operating a vehicle under the influence of alcohol or drugs. These charges are often more complex than they first appear and may involve roadside testing, breathalyzer results, prior convictions, and aggravating circumstances. Whether you are facing a first-time offense or a felony-level charge such as manslaughter while operating under the influence, we are here to protect your rights and build a strong legal defense.

Understanding DUI Charges Under New Hampshire Law

Driving under the Influence in New Hampshire is formally referred to as Operating Under the Influence (OUI) and is governed by RSA 265-A. The following are some of the most frequent accusations we defend against:

Drunk Driving (RSA 265-A:2)

Drunk Driving (RSA 265-A:2) is the base offense of operating a vehicle while under the influence of alcohol or a controlled substance. You can be charged if your blood alcohol concentration (BAC) is 0.08% or higher (or 0.02% for drivers under 21).

OUI Penalties (RSA 265-A:18)

Penalties for a DUI conviction in Brentwood (RSA 265-A:18) may include mandatory license suspension, fines, required participation in alcohol education programs, and even jail time for repeat offenses or aggravated cases. A first offense carries a minimum license suspension of 9 months, but it can go up to 2 years, depending on the facts.

Field Sobriety Tests and Breathalyzer Results (RSA 265-A:4)

Officers often use field sobriety tests and breathalyzer machines to determine impairment (RSA 265-A:4). However, these tests can be flawed, and breathalyzer results are subject to strict procedures. If these procedures are not followed properly, the evidence may be challenged in court.

Aggravated DUI and Manslaughter While Operating Under the Influence (RSA 265-A:3 and RSA 630:2)

You may face felony-level charges if your DUI resulted in serious injury or death. Under RSA 630:2, a driver can be charged with manslaughter if someone dies as a result of driving under the influence—a charge that can carry significant prison time if convicted.

Why Choosing the Right DUI Defense Attorney Matters

DUI cases are not open-and-shut. The evidence used by law enforcement can be challenged on several fronts—whether it’s a faulty breathalyzer test, improper stop, or mishandling of field sobriety test protocols.

At the Law Office of Matthew W. Peterson, we take each DUI case seriously. Our attorneys review every detail, from the traffic stop to how the evidence was collected. We work with you to create a personalized legal strategy that aims to reduce or dismiss the charges whenever possible.

Our firm’s experience also includes having a former prosecutor on our team. This gives us valuable insight into how the other side thinks and allows us to anticipate and challenge the prosecution’s strategy effectively.

What You Could Be Facing After a DUI Arrest in Brentwood

When you’re charged with DUI, you’re likely wondering what happens next. Here’s a breakdown of potential outcomes:

  • License Suspension: Immediate administrative suspension by the DMV, and potentially a court-ordered suspension if convicted.

  • Fines and Fees: DUI convictions often come with hundreds or even thousands in fines, surcharges, and court costs.

  • Criminal Record: Even a first-time DUI will appear on your criminal record, affecting employment and background checks.

  • Ignition Interlock Device (IID): For certain offenses, you may be required to install an IID at your own expense.

  • Jail Time: Particularly for repeat offenses or aggravated cases, incarceration is a real possibility.

How We Can Help You Fight a DUI Charge

When you work with the Law Office of Matthew W. Peterson, our first step is to conduct a thorough review of your case. We examine the details of the traffic stop to determine if law enforcement followed proper procedure. If your constitutional rights were violated or the stop lacked legal justification, we may be able to challenge the arrest itself.

In cases where negotiation is appropriate, we may work with prosecutors to seek reduced penalties or alternative sentencing options. However, we always prepare every case as if it is going to trial. Our legal strategy is designed to protect your rights, reduce the impact of the charges, and, when possible, secure a dismissal or not-guilty verdict.

Throughout the entire process, we provide straightforward communication and legal guidance tailored to your specific circumstances. We believe every client deserves a serious defense, and we are committed to helping you move forward with confidence.
