On Behalf of | Apr 14, 2026 | Drunk Driving Defense

A driving while impaired (DWI) charge in New Hampshire carries immediate and long-term consequences that disrupt your life, career and reputation. The state enforces strict drunk driving laws, and the legal process begins the moment a law enforcement officer pulls you over.

You face a variety of penalties that extend far beyond a simple traffic ticket, affecting your freedom and your ability to drive. Understanding these legal outcomes is crucial if you want to address the charges correctly.

What are the legal consequences of drunk driving?

The penalties for impaired driving vary depending on the severity of the incident and your prior driving history. Prosecutors seek different levels of punishment depending on whether the incident involved property damage, injury or loss of life. The following list outlines the primary legal ramifications you may encounter throughout the legal process.

  • DUI/DWI charges: A conviction means license suspension ranging from nine months to two years. You will also face hefty fines and potential jail time. For an aggravated DWI, which involves a high blood alcohol concentration or speeding, the court imposes mandatory minimum jail sentences.
  • Vehicular manslaughter charges: If a person dies as a result of impaired driving, the state elevates the charge to a felony. 
  • Ignition interlock devices (IIDs): The court often requires the installation of an IID in your vehicle at your own expense. This device measures your breath for alcohol before the engine starts.

Beyond the courtroom, a conviction triggers secondary consequences that last for years. You will likely see much higher insurance rates as providers label you a high-risk driver. A criminal record creates a lasting career impact, as many employers refuse to hire individuals with recent alcohol-related convictions.

Understand the importance of a strong defense

A DWI charge threatens your freedom and your livelihood, making a strong defense strategy essential for protecting your future. By thoroughly examining every piece of evidence held by the state, you ensure that the court hears your side of the story and respects your rights as a defendant.
