  2. Administer a breathalyzer test.
  3. Arrest the driver if tests indicate impairment.
  4. Transport the driver to the police station for booking.

The arraignment is the first court appearance where the defendant is formally charged. The defendant can plead guilty, not guilty, or no contest.

Pre-Trial Motions

Pre-trial motions may include:

  • Motion to Suppress: Challenging the legality of the traffic stop or evidence.
  • Motion to Dismiss: Requesting the case be dismissed due to lack of evidence.

Trial

If the case goes to trial, it will be heard by a judge or jury. The prosecution must prove beyond a reasonable doubt that the defendant was driving under the influence.

Sentencing

If found guilty, the judge will impose a sentence based on statutory guidelines and the specifics of the case.

Relevant Statutes

Administrative Penalties

License Suspension

The New Hampshire Division of Motor Vehicles (DMV) imposes administrative penalties, including license suspension, independent of criminal proceedings.

Under RSA 265-A:4, New Hampshire's implied consent law requires drivers to submit to chemical tests if suspected of DUI. Refusal results in automatic license suspension:

  • First Refusal: 180 days.
  • Subsequent Refusals: 2 years.

Ignition Interlock Device

An ignition interlock device (IID) may be required for reinstatement of driving privileges. The IID prevents the vehicle from starting if the driver's BAC exceeds a preset limit.

Relevant Statutes

  • Fines: Substantial monetary penalties.

Relevant Statutes

  • RSA 630:2: Details vehicular manslaughter laws.

DUI Defense Strategies

Challenging the Traffic Stop

A common defense is to challenge the legality of the traffic stop. If the stop was unlawful, evidence obtained may be inadmissible.

Questioning Test Accuracy

Defense attorneys may question the accuracy of breathalyzer or field sobriety tests, citing improper calibration or administration.

Medical Conditions

Certain medical conditions can mimic impairment. A defense may argue that symptoms were due to a medical issue rather than intoxication.

Relevant Statutes

  • RSA 265-A:14: Provides grounds for challenging DUI charges.
