Whether you’re facing a first-time drunk driving offense or more serious charges like Manslaughter While Operating Under the Influence, we take your case seriously and personally. DUI laws in New Hampshire are complex, and penalties can be severe, but with the right legal strategy, there are often opportunities to challenge evidence or reduce consequences.

Understanding DUI and OUI Charges in New Hampshire

In New Hampshire, DUI is legally referred to as “OUI”—Operating Under the Influence. Under RSA 265-A:2, it is unlawful to operate a motor vehicle while under the influence of alcohol or any controlled drug that impairs your ability to drive. This applies even if your blood alcohol concentration (BAC) is below 0.08%. If there is evidence of impairment, you could be charged with an OUI despite a low BAC because OUI also covers driving under the influence of other medications, such as

prescription medications, over-the-counter drugs, or any combination that affects your ability to drive safely. Additionally, if you are under the age of 21, your BAC only needs to be 0.02% to be charged.

If convicted of OUI in Hampton, the consequences may include:

  • Fines

  • Mandatory license suspension

  • Alcohol education programs

  • Potential jail time

  • Installation of an ignition interlock device

More severe penalties apply in cases involving aggravated DUI, underage DUI, or manslaughter while operating under the influence under RSA 630:2, which can result in lengthy prison sentences.

What to Expect After a DUI Arrest in Hampton

After a DUI arrest, you will likely be subject to field sobriety tests, breathalyzer tests, and formal charges. You’ll also face an administrative license suspension through the Department of Safety, separate from any criminal penalties.

Field sobriety tests, while often relied on by officers during roadside investigations, are not always accurate and can be challenged in court. Similarly, breathalyzer tests must be administered according to strict procedures to be valid. At the Law Office of Matthew W. Peterson, we analyze every step of your arrest to determine whether your rights were violated or whether errors were made that could lead to a dismissal or reduction in charges.

Frequently Asked Questions

What happens if I refuse a breathalyzer test in New Hampshire?

Refusing a breathalyzer test can lead to an automatic license suspension under New Hampshire’s implied consent law, even if you are not convicted of DUI. However, the refusal itself may be challenged in court depending on how the request was made and whether proper procedures were followed.

Yes. If the medication impairs your ability to drive safely, you can be charged with OUI—even if you have a valid prescription. These cases often rely on officer observations and can be defended with proper medical and legal analysis.

In New Hampshire, the terms are often used interchangeably. Legally, the charge is “Operating Under the Influence” (OUI), but many still refer to it as DUI or DWI. Regardless of the label, the legal consequences are the same.

Possibly. A DUI arrest may lead to both criminal and administrative license suspensions. You may request a hearing to challenge the suspension, but deadlines are strict. It’s important to speak with an attorney as soon as possible.

Not always. While jail is possible for a first offense, many cases result in fines, license suspension, and mandatory substance abuse programs. Aggravating factors like high BAC or having minors in the vehicle may increase penalties.
