First DWI Arrest in New Hampshire: Your First 30 Days Explained

A first DWI arrest in New Hampshire can begin two separate proceedings. One is a criminal DWI case in court. The other may be an Administrative License Suspension, or ALS, process through the New Hampshire Department of Safety.

If you receive an ALS notice after refusing a qualifying test or after a qualifying alcohol-concentration test result, the suspension is generally set to take effect 30 days after service of the notice. A request for an administrative review or hearing must be received by the Department of Safety within 30 days from the date the notice is issued. Missing that deadline can result in the suspension taking effect without the administrative challenge you could have requested.

For a standard first DWI conviction under RSA 265-A:2, I, current New Hampshire law generally classifies the offense as a Class B misdemeanor. The penalties include a fine of at least $500, referral to an Impaired Driver Care Management Program, required screening, an approved impaired-driver education program, a qualified online victim impact panel unless the court finds exceptional circumstances, and a court-imposed license revocation of at least nine months.

Tenn And Tenn, PA represents people facing DWI charges in Manchester and throughout New Hampshire. The firm helps clients understand court deadlines, license issues, testing evidence, and the decisions that may arise after an arrest.

Two proceedings can move at the same time. The criminal case and the ALS case have separate rules, deadlines, and consequences.

What Happens Right After a First DWI Arrest?

The hours after a first DWI arrest can involve several steps. Police may transport you to a police station, hospital, or another location for processing or chemical testing. Depending on the circumstances, your vehicle may be towed, released to another driver, or left in a lawful location.

You may receive paperwork that identifies the charge, court date, release conditions, testing information, and any notice affecting your driving privileges. Keep every document. Store the originals in a safe place and make copies for your records.

Why Can a First DWI Create Two Separate Proceedings?

The criminal DWI case is handled in court. The State must prove the charged offense beyond a reasonable doubt. Depending on the case, the court process may include an arraignment, discovery, pretrial conferences, motions, negotiations, and trial.

The ALS process is handled through the New Hampshire Department of Safety. Under current law, an ALS may follow a refusal of a qualifying test or a qualifying alcohol-concentration test result. For a driver age 21 or older, the administrative alcohol threshold is 0.08. For a driver under age 21, the administrative threshold is 0.02.

The two proceedings are separate. A license matter can be pending while the criminal case is still in its early stages. An outcome in one proceeding does not automatically decide the other.

What Is the 30-Day Administrative License Suspension Deadline?

If an officer serves an ALS notice, the suspension is generally scheduled to take effect 30 days after service. If you hold a valid New Hampshire driver license, the officer generally issues a temporary license that remains valid during the notice period.

A separate deadline applies to an administrative challenge. A written request for an administrative review or hearing must be received by the Department of Safety within 30 days from the date the notice is issued. A late request may be denied as untimely.

The ALS filing is separate from anything filed in the criminal court. Do not assume that appearing in court protects your administrative hearing rights.

Under current law, a first qualifying alcohol-concentration test result generally carries a six-month administrative suspension when there is no prior refusal, DWI conviction, aggravated DWI conviction, or prior ALS.

A first refusal currently carries a 180-day suspension when there is no prior DWI or aggravated DWI conviction.

A law taking effect January 1, 2027 changes several refusal-related rules. Among other changes, the first-refusal suspension increases from 180 days to nine months, certain later refusal suspensions increase to three years, and court-imposed DWI revocations will run consecutively to administrative suspensions or revocations covered by the statute. The law that applies can depend on the date of the alleged offense, so a person arrested near or after the effective date should confirm the governing rules.

What Happens at the First Court Appearance?

New Hampshire law directs officers, when practicable, to schedule an arraignment for a DWI charge no later than 14 business days after the alleged violation. The court date listed on your paperwork controls when and where you must appear.

An arraignment is generally not a trial. The court identifies the charge, addresses the plea, and may address release conditions and future scheduling. A not-guilty plea gives the defense time to obtain and review the prosecution’s evidence before later decisions are made.

Evidence in a first DWI case may include:

• Police reports
• Body-camera video
• Cruiser or dash-camera video
• Dispatch records
• Field sobriety test observations
• Breath-testing records
• Blood or urine laboratory records
• Witness statements
• Crash photographs
• Vehicle or electronic data, when available

The defense can compare police reports with video, test records, dispatch information, and other evidence. Differences in timing, instructions, observations, testing procedures, or recorded events may affect how the evidence is evaluated.

What Does the State Have to Prove in a New Hampshire DWI Case?

New Hampshire DWI law allows the State to proceed under more than one legal theory. A person may be charged based on alleged impairment by alcohol, drugs, or a combination of substances. A separate theory may rely on an alcohol concentration at or above the statutory limit.

A DWI case does not always turn on one breath or blood result. Driving behavior, police observations, statements, field sobriety testing, chemical testing, video, and surrounding circumstances may all become part of the evidence.

A defense review may examine questions such as:

• Was there a lawful basis for the traffic stop?
• Did the officer have sufficient legal grounds to expand the stop into a DWI investigation?
• Did probable cause support the arrest?
• Were field sobriety tests explained and administered properly?
• Could injury, physical limitations, footwear, fatigue, weather, or road conditions have affected performance?
• Were breath, blood, or urine testing procedures followed?
• Do video and other records support the officer’s written observations?
• Can the State prove that the person was driving or attempting to drive as required by the charged offense?
• Were required warnings and testing rights provided?

What Are the Penalties for a Standard First DWI Conviction?

A standard first DWI conviction under RSA 265-A:2, I is generally a Class B misdemeanor under current New Hampshire law.

The statutory consequences include:

• A fine of at least $500
• Referral to an Impaired Driver Care Management Program
• Alcohol and drug abuse screening within 14 days of conviction for a first-time offender
• A full substance use disorder evaluation within 30 days of conviction if the screening indicates the likelihood of a substance use disorder
• Compliance with the service plan developed after any required evaluation
• Completion of a Department of Health and Human Services approved impaired-driver education program before license restoration
• Completion of a qualified online victim impact panel unless the court finds exceptional circumstances
• A court-imposed license revocation of at least nine months and up to two years

The court may suspend up to six months of the license revocation when the statutory requirements are satisfied. Those requirements include timely screening, completion of any required evaluation, compliance with the service plan, and completion of the approved impaired-driver education program.

A standard first DWI is different from aggravated DWI. Certain statutory circumstances can increase the seriousness of the charge and the potential penalties.

What Should You Do During the First Few Days After a DWI Arrest?

The first few days are a useful time to organize documents, preserve information, and identify deadlines.

Consider these steps:

• Read every page provided by the police, court, and Department of Safety.
• Confirm the court date, time, and location.
• Check whether you received an ALS notice.
• Calendar the 30-day administrative review or hearing deadline if an ALS notice was issued.
• Confirm when any temporary driving privilege expires.
• Do not drive after your valid license or temporary privilege has ended.
• Write down what you remember about the stop, investigation, testing, statements, and arrest.
• Preserve receipts, messages, photographs, location information, and other records that may help establish a timeline.
• Save any relevant medical information if an injury, condition, medication, or physical limitation may have affected testing.
• Avoid posting detailed statements about the arrest on social media.
• Speak with a New Hampshire DWI lawyer before making major decisions about the case.

Can a First DWI Charge Be Challenged?

Yes. A first-offense label does not establish that the State can prove every required element of the charge. The available defense depends on the facts, the law, and the evidence in the individual case.

One case may focus on whether the traffic stop was lawful. Another may involve probable cause for arrest. A different case may turn on video, field sobriety testing, breath-testing records, blood-test handling, a medical issue, witness testimony, or proof that the person was driving or attempting to drive.

An attorney may be able to:

• Obtain police reports and discovery
• Request and review available video
• Compare reports with objective evidence
• Review breath, blood, or urine testing records
• Identify legal or procedural issues
• Represent a client in an ALS matter when appropriate
• File motions when supported by the law and facts
• Negotiate with the prosecution
• Prepare the case for trial when necessary

No attorney can promise that a DWI charge will be dismissed, reduced, or resolved in a particular way. The result depends on the applicable law, the admissible evidence, and the facts of the case.
