Driving While Intoxicated (DUI) charges in New Hampshire are prosecuted under New Hampshire Revised Statutes Annotated (RSA) 265-A and may carry significant criminal penalties and driver’s license consequences depending on the circumstances of the arrest and any prior record.

DUI investigations frequently involve roadside observations, field sobriety testing, breath or blood testing procedures, and statements made during a traffic stop. Because early decisions can affect both criminal court proceedings and administrative license suspension consequences, speaking with a defense attorney as soon as possible can be important.

In many situations, individuals first learn about the full consequences of a DUI arrest after receiving notice of an immediate administrative license suspension from the New Hampshire Division of Motor Vehicles (DMV).

Common DUI Charges in New Hampshire

New Hampshire law recognizes several types of DUI-related offenses depending on prior history and surrounding circumstances.

Because penalties increase significantly with prior offenses and aggravating factors, early evaluation of record history and license consequences is especially important.

Administrative License Suspension in New Hampshire DUI Cases

Following a DUI arrest in New Hampshire, individuals may face an Administrative License Suspension (ALS) separate from the criminal court process under RSA 265-A:31.

Administrative suspension proceedings may begin quickly after arrest and involve strict deadlines to request a hearing.

Because ALS consequences can begin before the criminal case is resolved, addressing administrative issues early can be critical.

Breath Tests, Blood Tests, and Refusal Allegations

New Hampshire’s implied consent law under RSA 265-A:4 allows law enforcement officers to request breath or blood testing during a DUI investigation.

Refusing a chemical test may result in administrative license suspension consequences separate from the criminal case.

Because refusal allegations involve both DMV and court consequences, early case evaluation can be especially important.

Field Sobriety Testing and Evidence in DUI Cases

DUI prosecutions frequently depend on interpretation of multiple types of evidence gathered during a traffic stop.

This evidence may include:

  • officer observations
  • field sobriety testing
  • roadside statements
  • breath testing procedures
  • blood test results
  • cruiser video evidence

Careful evaluation of how this evidence was obtained often becomes central to determining how a case proceeds.

Aggravated DUI Charges in New Hampshire

Some DUI cases involve allegations that prosecutors classify as Aggravated DUI under RSA 265-A:3, including cases involving:

  • elevated alcohol concentration levels
  • excessive speed
  • attempting to avoid police
  • transporting a minor while impaired
  • causing a collision resulting in injury

Aggravated DUI allegations may involve enhanced penalties and longer license suspension exposure.

Felony DUI Charges in New Hampshire

Certain DUI prosecutions may result in felony-level exposure depending on prior record history or allegations involving injury or death.

Felony DUI cases frequently involve:

  • third-offense DUI allegations
  • fourth-offense DUI allegations
  • DUI causing serious bodily injury
  • DUI negligent homicide allegations

These cases are typically handled in New Hampshire Superior Court and often involve complex evidentiary and sentencing considerations.

Learn more:

Because felony-level allegations may significantly increase potential penalties, early legal representation can be especially important.

DUI Charges Involving Drugs or Marijuana

New Hampshire law permits DUI prosecutions involving impairment by substances other than alcohol under RSA 265-A:2.

These cases frequently involve:

  • prescription medications
  • marijuana-related impairment allegations
  • controlled substance investigations
  • officer observations during roadside evaluations

Learn more:

Because drug-based DUI prosecutions often depend heavily on officer observations rather than chemical testing, early case evaluation can be critical.

Evidence Issues in New Hampshire DUI Cases

DUI investigations frequently involve legal questions concerning:

  • traffic stop justification
  • roadside investigation procedures
  • field sobriety testing interpretation
  • breath or blood testing procedures
  • statements made during investigation
  • constitutional search issues

Evaluation of these issues often becomes central to determining how a case proceeds.
