NH Aggravated DWI (.16+ BAC): Restricted Privilege Eligibility

New Hampshire law defines aggravated DWI under RSA 265-A:3 as operating a vehicle with a blood alcohol concentration of .16 or higher, twice the state's .08 legal limit. This classification is not discretionary — if your BAC test result meets or exceeds .16, the charge is automatically aggravated regardless of driving behavior, prior record, or mitigating circumstances. The aggravated classification extends your mandatory hard suspension period from the standard first-offense timeline to 9 months minimum under RSA 265-A:18. During this 9-month period, you cannot apply for a restricted driving privilege — no exceptions for employment, medical appointments, or educational needs. The hard suspension begins the day the court issues the revocation order, not the arrest date. After the 9-month hard period ends, you become eligible to petition the sentencing court for a restricted driving privilege under RSA 265-A:30, but approval is not automatic. The court retains full discretion to deny your petition even if you have completed the mandatory Impaired Driver Care Management Program (IDCMP) enrollment and installed an ignition interlock device. Standard first-offense DWI in New Hampshire carries a 6-month total revocation, with restricted privilege eligibility available sooner for drivers who install an IID and enter IDCMP — aggravated DWI eliminates that early-access pathway entirely.

New Hampshire does not grant restricted driving privileges administratively through the DMV for DWI-based suspensions. You must petition the sentencing court that issued your revocation order, and that court holds jurisdiction over whether to grant, deny, or revoke your restricted privilege at any point during the filing period. Your petition must include proof of IDCMP enrollment or completion, proof of ignition interlock device installation by a state-approved vendor, and an SR-22 financial responsibility certificate filed with the DMV. New Hampshire does not require auto insurance by law for most drivers, but DWI convictions trigger a mandatory financial responsibility requirement — SR-22 is the most common method to satisfy it, though a surety bond (approximately $75,000) or cash deposit are legal alternatives under RSA 264. The court will review your petition in a hearing. You must demonstrate specific need — typically employment, medical treatment, or court-ordered obligations like IDCMP classes. The court will specify approved routes, approved hours, and approved purposes in the order granting the privilege. Operating outside those restrictions, even by a single mile or minute, constitutes a separate criminal offense and typically results in immediate revocation of the restricted privilege plus additional charges. Most courts in New Hampshire do not charge a separate application fee for the petition itself, but you pay the DMV's $100 reinstatement fee when the restricted privilege is issued, plus ignition interlock installation (typically $70-$150) and monthly IID monitoring fees (typically $60-$90/month). Total cost over the restricted-privilege period commonly exceeds $3,000 when SR-22 premium increases are included.

RSA 265-A:36 mandates ignition interlock installation as a condition of any restricted driving privilege following an aggravated DWI conviction. The device must be installed by a state-approved vendor — New Hampshire maintains a list of certified providers on the DMV website — and you must provide installation receipts to the court before your restricted privilege order is signed. The device requires a breath sample below .025 BAC to start the vehicle, and random rolling retests while driving. Failed tests, missed rolling retests, or tampering attempts are logged and reported to the court and DMV. A single failed retest can trigger immediate revocation of your restricted privilege, and New Hampshire law treats tampering with an IID as a separate Class A misdemeanor under RSA 265-A:36-a. You pay all costs associated with the device: installation, monthly calibration and monitoring, and removal after the restricted period ends. Many drivers assume installation is a one-time expense — it is not. Monthly fees continue for the duration of your restricted privilege, which for aggravated DWI typically runs the remainder of the revocation period after the 9-month hard suspension. If you do not own a vehicle, you must still install an IID in any vehicle you intend to operate under the restricted privilege, including employer-owned vehicles if your job requires driving. New Hampshire does not offer an employment exemption for IID requirements. If you cannot install a device because you do not own or have access to a vehicle, the court will not grant a restricted privilege — non-owner SR-22 insurance satisfies the financial responsibility filing but does not bypass the IID mandate.

New Hampshire requires SR-22 financial responsibility filing for 3 years following a DWI conviction, measured from the date the DMV receives the SR-22 certificate, not the conviction date or the restricted privilege issuance date. The 3-year clock does not start until you file, so delays in obtaining SR-22 insurance extend your total compliance period. SR-22 is not a type of insurance — it is a certificate your insurer files electronically with the New Hampshire DMV certifying you carry at least the state-required financial responsibility. Because New Hampshire does not mandate auto insurance for most drivers, the state requires only that DWI offenders prove they can cover liability damages: $25,000 per person for bodily injury, $50,000 per accident, and $25,000 for property damage. Most SR-22 policies meet these minimums exactly to reduce premium cost. If your SR-22 policy lapses or cancels for any reason during the 3-year filing period, your insurer notifies the DMV electronically within 24 hours, and the DMV suspends your license or restricted privilege immediately. New Hampshire does not provide a grace period for SR-22 lapses tied to DWI convictions. Reinstatement after a lapse-triggered suspension requires filing a new SR-22, paying a new $100 reinstatement fee, and potentially re-petitioning the court if your restricted privilege was revoked due to the lapse. Carriers writing SR-22 in New Hampshire include Geico, Progressive, The General, Bristol West, and National General. Monthly SR-22 premiums for aggravated DWI convictions typically range from $140 to $240 per month depending on age, county, and vehicle. Non-owner SR-22 policies — for drivers without a vehicle — typically cost $30 to $60 per month and satisfy the filing requirement but do not allow you to operate a vehicle under a restricted privilege unless that vehicle has an IID installed.

Operating outside the approved routes, hours, or purposes specified in your court order is not a minor infraction. New Hampshire treats restricted privilege violations as a separate Class B misdemeanor under RSA 265-A:30, carrying potential jail time, additional fines, and immediate revocation of the restricted privilege with no right to reapply. The court will also likely extend your total revocation period, and the DMV will not credit time served under the restricted privilege toward your original suspension. If you had 6 months remaining on your revocation when the violation occurred, you start over with a new 6-month revocation after the court processes the violation, plus any additional penalties the court imposes. Ignition interlock violations — failed rolling retests, missed calibrations, or tampering — also trigger immediate revocation. The IID vendor reports violations to both the court and the DMV, and most courts in New Hampshire revoke restricted privileges after a single confirmed failed test above .025 BAC. Some judges require a 30- or 60-day waiting period before you can re-petition after a violation, effectively adding months to your total restricted-privilege period. If your SR-22 lapses during the restricted-privilege period, the DMV suspends your restricted privilege administratively, and you cannot legally drive — even to work, even within previously approved hours — until you refile SR-22, pay the $100 reinstatement fee, and receive confirmation from the DMV that the suspension is lifted. Many drivers assume they can continue driving if they refile SR-22 the same day — this is incorrect. The suspension remains active until the DMV processes the new filing, which typically takes 3 to 5 business days.

When your full revocation period ends — including any restricted-privilege time — you must apply for full license reinstatement with the New Hampshire DMV. Reinstatement is not automatic. You must provide proof of IDCMP completion (not just enrollment), proof of continuous SR-22 filing for the required 3-year period, and payment of the $100 reinstatement fee. The DMV does not require a written retest for standard first-offense or aggravated DWI reinstatement in most cases, but the agency retains discretion to order retesting if your driving record shows additional violations during the suspension period. Some counties require a vision test at reinstatement regardless of offense type. Your SR-22 filing requirement continues for 3 years from the date you initially filed, not 3 years from reinstatement. If you filed SR-22 during your restricted-privilege period, that time counts toward the 3-year total. If you delayed filing until full reinstatement, the 3-year clock starts the day the DMV receives your certificate, extending your total compliance burden. After reinstatement, your license returns to full driving privileges, but your aggravated DWI conviction remains on your New Hampshire driving record permanently under state law. Insurers can see the conviction indefinitely, and most carriers apply DWI surcharges for 5 to 7 years after the conviction date, not the reinstatement date. Expect premiums to remain elevated well beyond the end of your SR-22 filing period.

Not all carriers accept aggravated DWI risks, and those that do often apply underwriting restrictions or county-specific availability limits. Geico, Progressive, Bristol West, The General, and National General write post-DWI SR-22 policies in New Hampshire, but approval and pricing vary significantly by BAC level, prior violations, and zip code. Carriers classify aggravated DWI differently from standard DWI for underwriting purposes. Some apply a flat surcharge regardless of BAC; others tier pricing at .15, .16, and .20+ thresholds. A driver with .16 BAC may receive a quote $40 to $80 higher per month than a driver with .10 BAC, even with identical driving history otherwise. Non-owner SR-22 policies are available from most of the same carriers and cost substantially less — typically $30 to $60 per month — but provide no physical-damage coverage and do not allow you to operate a vehicle unless that vehicle is separately insured and equipped with an IID. Non-owner policies satisfy the SR-22 filing requirement and keep your license or restricted privilege valid, making them the correct choice for drivers who sold their vehicle after the arrest, lost the vehicle to impound, or rely on public transit and employer-provided vehicles. Carrier appetite for aggravated DWI risks tightens when combined with other violations. If your record shows a prior DWI within 10 years, a refusal charge, or multiple at-fault accidents, fewer than five carriers in New Hampshire will quote coverage, and premiums commonly exceed $250 per month. Some drivers are declined entirely and must seek coverage through the state's assigned-risk pool or surplus-lines market, both of which carry higher premiums and limited coverage options.
