Cost of a Hardship License After a DUI in New Hampshire

New Hampshire does not publish a standard application fee for its Restricted Driving Privilege program because the petition process runs through the sentencing court, not the DMV. Court filing fees vary by county and case type, typically ranging from $100 to $250. The $100 DMV reinstatement fee listed in statute (RSA 263:42) applies separately—it restores your full license after the suspension period ends, not when you receive restricted driving approval. Ignition interlock installation adds $75 to $150 upfront, then $65 to $100 monthly for device rental and calibration. RSA 265-A:36 mandates IID for all DUI offenders seeking restricted privileges. If you petition 90 days into a 9-month suspension and drive restricted for 6 months, the IID alone costs $465 to $750. SR-22 filing is required for three years post-conviction. Carriers charge $15 to $50 to file the certificate, then raise your premium. A typical New Hampshire driver with a first DUI pays $140 to $240 per month for liability coverage with SR-22, compared to $85 to $120 before the conviction. Over three years, that premium increase totals $1,980 to $4,320.

The sentencing court retains jurisdiction over Restricted Driving Privilege petitions for DWI-based suspensions under New Hampshire law. You file directly with the court that handled your conviction, not with the DMV. Attorney representation is not legally required, but courts deny pro se petitions at higher rates when employment affidavits are vague or route documentation is missing. Attorney fees for a petition hearing range from $500 to $1,500 depending on case complexity. If the court denies your petition, you wait 30 to 90 days to refile in most jurisdictions, paying a second filing fee and additional attorney time. The court sets your approved routes, hours, and purposes in the order—deviation from those terms triggers immediate revocation without warning. Because New Hampshire does not mandate auto insurance as a baseline requirement, the state's financial responsibility system is triggered only after conviction. Most DUI offenders learn about SR-22 requirements at the reinstatement counter, not at sentencing, creating a second surprise cost months after the court hearing.

For a first DWI offense, RSA 265-A:30 typically imposes a 9-month hard suspension before restricted privilege eligibility. You cannot petition the court until that period ends, though some courts allow filings 30 days before the eligibility date. The Impaired Driver Care Management Program (IDCMP) assessment and enrollment must begin during the hard suspension—completion or active participation is a prerequisite to restricted driving approval. IDCMP consists of multiple phases: initial assessment, treatment classes, and ongoing monitoring. Total program cost ranges from $400 to $1,200 depending on assessment results and required treatment intensity. You pay IDCMP fees during the hard suspension, before restricted driving begins. Many offenders budget for the court petition and IID but overlook IDCMP costs until the court denies their petition for incomplete enrollment. The DMV reinstatement fee applies only after your full suspension period ends. If you serve 3 months of hard suspension plus 6 months of restricted driving, you pay the $100 reinstatement fee at month 9, along with proof of IDCMP clearance and continued SR-22 coverage. The SR-22 filing period continues for three years from conviction, not from reinstatement.

Non-owner SR-22 policies cost $25 to $50 per month in New Hampshire, substantially less than standard liability coverage. If your vehicle was impounded, sold, or you never owned one, a non-owner policy satisfies the state's financial responsibility requirement without insuring a specific car. You still need the policy for three years. The ignition interlock requirement does not disappear when you lack a vehicle. Courts typically require IID installation in any vehicle you intend to drive under the Restricted Driving Privilege order—employer vehicles, family vehicles, or rental cars if the rental company permits it. Some employers refuse to allow IID installation in company vehicles, which eliminates work commute approval and collapses the basis for your petition. If you cannot install IID in an available vehicle, the court denies restricted driving eligibility even when all other petition requirements are met. This creates a scenario where you pay for IDCMP, court filing, and SR-22 filing before learning your petition will fail due to vehicle access.

Refusal of a chemical test under RSA 265-A:14 triggers a separate 180-day administrative suspension on top of any court-imposed DUI suspension. The two suspensions run concurrently in most cases, but refusal cases face longer hard suspension periods before restricted driving eligibility—typically 12 months instead of 9 for first offenses. Second DUI offenses within 10 years face mandatory minimum 3-year suspensions with longer IID requirements post-reinstatement. Restricted driving privileges may be denied entirely at judicial discretion. Attorney representation becomes functionally mandatory for second-offense petitions, raising upfront costs to $1,500 to $3,000 before the court rules. SR-22 filing periods extend to 5 years for second offenses in some states, though New Hampshire statute does not explicitly mandate this—verify current requirements with your carrier and the DMV. Premium increases compound: a second DUI often places you in non-standard carrier territory, where monthly rates run $200 to $350 with SR-22.

Court petition filing fee: $100 to $250. Attorney representation (optional but common): $500 to $1,500. IDCMP assessment and treatment: $400 to $1,200. Ignition interlock installation: $75 to $150. Ignition interlock monthly rental for 6 months restricted driving: $390 to $600. SR-22 filing fee: $15 to $50. Premium increase over 3 years: $1,980 to $4,320. DMV reinstatement fee at end of suspension: $100. Total first-year cost for a typical scenario: $3,560 to $7,170. That assumes no petition denial, no IID violation fees, no additional court hearings, and completion of IDCMP on the first assessment cycle. Denials, delays, and violations push totals higher.
