A first-offense DWI in New Hampshire is typically charged as a Class B misdemeanor, carrying a minimum $500 fine and a license revocation of 9 months to 2 years under RSA 265-A:18. Up to 6 months of that revocation can be suspended if you comply with mandatory screening. The court refers you to an Impaired Driver Care Management Program (IDCMP), which requires screening within 14 days of conviction and, if warranted, a full evaluation within 30 days. Here is what to do right away:
- Request a certified copy of your driving record
- Schedule your IDCMP screening before the 14-day clock runs out
- Consult a New Hampshire DWI attorney before your arraignment

NH DWI First Offense Penalties Under RSA 265-A:18
A standard first offense DWI in New Hampshire is a Class B misdemeanor. The statute sets a minimum fine starting at several hundred dollars, and courts add penalty assessments on top of that base amount, so the total owed at sentencing usually runs higher than the headline figure.
Statistic Callout: New Hampshire’s own transportation guidance puts the realistic penalty range for a first-time offense at fines ranging from several hundred to a few thousand dollars, alongside license suspension and, in some cases, jail exposure, according to the NH Department of Transportation.
A first offense stops being a routine, non-aggravated case when certain facts show up in the record. These push penalties toward the harsher end of what the statute allows:
- Blood alcohol concentration well above the 0.08% legal limit
- An accident that caused bodily injury
- A minor passenger in the vehicle at the time of the stop
- Refusal to submit to testing under NH’s implied consent rules
Judges weigh these facts alongside your driving history and how quickly you engage with the IDCMP process. A defendant who screens promptly and shows compliance often fares better at sentencing than one who delays. For a fuller breakdown of how these penalties escalate, our overview of NH DWI penalties walks through the aggravated categories in more detail.
How Long Will Your License Be Revoked?
New Hampshire courts revoke driving privileges for not less than 9 months and not more than 2 years following a first DWI conviction, per RSA 265-A:18. The statute also gives judges room to suspend up to 6 months of that minimum revocation, but only if you meet specific conditions.
- Complete your IDCMP screening within 14 days of conviction
- Finish a full evaluation within 30 days if the screening flags a substance use concern
- Follow the resulting service plan without gaps in compliance
An ignition interlock device may be ordered as a condition of any restricted or restored license, particularly when BAC results were elevated or the court wants added assurance before reinstatement. To restore driving privileges once revocation ends, you’ll typically need proof of IDCMP completion, any required education certificates, and payment of reinstatement fees to the DMV.
Pro Tip: If you hold an out-of-state license, New Hampshire will still require you to satisfy its IDCMP and revocation terms before your home state will lift any reciprocal action against your driving record.
What Happens Between Arraignment and Sentencing?
Your case moves through a fairly predictable sequence: arraignment, pretrial hearings where plea negotiations or motions get filed, and finally sentencing. How much time passes between each step depends on court scheduling and whether your attorney raises evidentiary challenges worth litigating.
At sentencing, the judge documents the outcome using the New Hampshire Judicial Branch’s DWI first-offense sentencing order, a standardized form (NHJB-2642-Se) that records the fine, the revocation period, whether any portion is suspended, and any IDCMP or interlock conditions attached to your sentence.
Compliance with IDCMP recommendations before sentencing genuinely changes what that form says. Judges routinely use the 6-month suspension provision as leverage, granting it only when the record shows you already screened on time.
Before your hearing:
- Gather proof of any completed screening or evaluation appointments
- Bring your certified driving record
- Ask your attorney whether a plea negotiation makes sense given the facts
How the IDCMP Screening and Evaluation Process Works
The Impaired Driver Care Management Program isn’t optional paperwork. It’s a statutory requirement under RSA 265-A:40, administered through IDCMPs that New Hampshire’s Department of Health and Human Services approves and monitors.
- Screening must happen within 14 days of conviction
- If screening indicates a substance use disorder, a full evaluation follows within 30 days
- The IDCMP develops a service plan and reports your compliance to the court and DMV
| Requirement | Timeline |
|---|---|
| Initial screening | Within 14 days of conviction |
| Full evaluation (if indicated) | Within 30 days of conviction |
| Service plan components | Education, treatment referral, monitoring, sometimes a victim-impact panel |
| Reporting | IDCMP reports compliance status to court and DMV |
Fees vary by provider and program component, though waivers exist for defendants who qualify financially, per DHHS rules. Falling out of compliance carries real consequences: the court can revoke any suspended portion of your revocation, and the DMV may extend administrative hold on your license until you catch up.
Does a DWI Conviction Stay on Your Record Forever?
A first-offense DWI conviction lands on both your criminal record and your DMV driving record, and insurers see it. Expect your premiums to climb, often substantially, for several years following conviction, according to NH DOT’s collateral-consequences guidance.
Statistic Callout: New Hampshire law gives you one real avenue for relief: RSA 265-A:18 allows a court to reduce a DWI conviction to a violation-level offense once at least one year has passed, provided your driving record, IDCMP compliance, and any hardship factors support the motion.
- A reduced conviction can ease certain employment and licensing barriers tied to a misdemeanor record
- New Hampshire does not offer expungement or sealing for DWI convictions outright
- The one-year clock starts at conviction, not arrest, so timing your motion matters
What Should You Do in the First 72 Hours?
The choices you make immediately after arrest shape everything that follows, from whether the court suspends part of your revocation to what evidence your attorney can preserve.
- Request a certified copy of your driving record and the police report
- Call an approved provider and lock in your IDCMP screening appointment inside the 14-day window
- Check for any DMV administrative hearing deadline. Missing it can trigger automatic suspension separate from the criminal case
- Contact an experienced New Hampshire DWI attorney and bring your arrest paperwork, the citation, and any breath or blood test documentation to that first meeting
Pro Tip: Ask the arresting agency for breath-test calibration records early. These logs are sometimes the deciding factor in whether a suppression motion holds up, and they take time to request.

Why Local Counsel Matters in a First-Offense Case
Naro Law handles first-offense DWI cases across New Hampshire’s district and superior courts, and that local familiarity shows up in practical ways: knowing which IDCMP providers move fastest on the 14-day screening, and which judges give real weight to early compliance when deciding whether to suspend part of a revocation.
Counsel can also file the motion to reduce a conviction to a violation once you hit the one-year mark, if your record supports it. A free consultation typically covers your arrest paperwork, test results, and driving history. Bring what you have, even if the picture feels incomplete.

Getting Ahead of the Deadlines That Actually Decide Your Case
Most people fighting a first-offense DWI focus on the fine, since it’s the number that shows up first. The fine matters far less than the 14-day and 30-day IDCMP deadlines. Miss those, and the judge loses the statutory basis to suspend part of your revocation. Hit them, and you’ve handed your attorney real leverage at sentencing.
That’s the part conventional advice skips. Court forums and generic legal blogs tell you to “consult an attorney,” which is true but incomplete. The more useful insight is that New Hampshire’s statute rewards speed. A defendant who screens on day 3 is in a fundamentally different negotiating position than one who screens on day 13, even though both technically complied.
The one-year reduction provision gets overlooked too, often because people assume a DWI conviction is permanent and stop looking for options once sentencing ends. It isn’t permanent, but the court won’t offer it. You have to ask, with a Hartland man charged with DUI after crash clean compliance record backing the motion.
If there’s one thing worth arguing against the conventional wisdom, it’s this: the case isn’t won or lost in the courtroom nearly as often as it’s won or lost in the first two weeks, in a screening appointment most defendants treat as an afterthought.
