Legal Process
A DUI case in New Hampshire is heard in the Circuit Court, District Division, and it runs on two tracks at once: the criminal case and a separate licence action you must challenge within 30 days of arrest.
- 1Arrest, booking and the chemical test — Officers arrest for DUI under N.H. Rev. Stat. Ann. § 265-A:2 and request a breath, blood or urine test under New Hampshire's implied-consent section, N.H. Rev. Stat. Ann. § 265-A:4. Refusing carries its own licence penalty, separate from the criminal charge.
- 2Licence action — request a hearing within 30 days — Administrative Licence Suspension is imposed under RSA 265-A:30 for a refusal or a test result of 0.08 or more. You have 30 days from arrest to demand the administrative hearing with New Hampshire Department of Safety, Division of Motor Vehicles; miss it and the suspension takes effect automatically, whatever happens in court.
- 3Arraignment in the Circuit Court, District Division — The charge is read, a plea is entered and conditions of release are set in the Circuit Court, District Division. New Hampshire misdemeanor DWI is heard in the Circuit Court, District Division, while felony-level impaired driving — aggravated DWI with prior felony convictions, or a case causing death — is heard in Superior Court.
- 4Pretrial motions and discovery — Defence counsel obtains the police report, test records and calibration or maintenance logs, and may move to suppress the stop or the test result. The New Hampshire Judicial Branch runs a statewide electronic filing system for Circuit and Superior Court matters.
- 5Plea or trial, then sentencing — A first DUI conviction carries a fine of $500–$1,000, a licence suspension of 9 months. Prior offenses within 10 years push the case into the enhanced-penalty range. A first offense carries a fine and a suspension usually measured in months, not weeks.
- 6Appeal — An administrative licence suspension appeal goes to Superior Court in the county of residence within 30 days of the final decision under RSA 263:76.
- 7Reinstatement — New Hampshire requires a SR-22 certificate of financial responsibility for 3 years before the licence is restored.
New Hampshire misdemeanor DWI is heard in the Circuit Court, District Division, while felony-level impaired driving — aggravated DWI with prior felony convictions, or a case causing death — is heard in Superior Court. Appeals from the district division and from DMV licence actions go to Superior Court.
