Understanding the Financial Penalties for DWI Charges in New Hampshire
In New Hampshire, being convicted of DWI (Driving While Intoxicated) comes with more than just legal consequences—it carries significant financial penalties. While most drivers are aware that fines exist, many are surprised to discover just how quickly the total cost can escalate. Between court-imposed fines, mandatory surcharges, and related administrative costs, the final amount can easily reach thousands of dollars, even for a first offense.
This article breaks down the full scope of DWI fines in New Hampshire. It explains the base fines set by law, how surcharges are applied, how the costs increase for repeat offenses or aggravated cases, and the additional financial burdens that come with every conviction. If you’re facing a charge or trying to understand how penalties work, this guide outlines what to expect when it comes to DWI-related financial obligations in the Granite State.
Minimum Fines for First-Time DWI Offenses
Under New Hampshire law, a first offense DWI is typically classified as a Class B misdemeanor. This is still a criminal charge and comes with mandatory minimum fines that must be paid upon conviction.
For a standard first-offense DWI:
- Minimum fine: $500
- Mandatory penalty assessment: 24% surcharge on top of the base fine
- Total minimum payment: $620 (including surcharge)
This fine is not negotiable and must be paid to the court. Even if no accident occurred and there are no aggravating circumstances, the fine applies upon conviction or plea.
However, this is only the beginning. A DWI conviction also triggers additional costs beyond the court-imposed fine.
Additional Costs That Accompany a DWI Fine
The court fine is only one part of the total financial impact. Drivers convicted of DWI in New Hampshire will face a range of other required payments, including:
- Alcohol or drug education program: Required for all offenders. Costs range from $300 to $600.
- License reinstatement fee: Paid to the DMV to reinstate driving privileges after suspension. Typically $100.
- Insurance rate increases: High-risk drivers pay significantly more. Costs vary, but premiums may rise by $1,000+ annually.
- Ignition interlock device (if ordered): Installation fee plus monthly service. Can cost $70–$100 per month.
- Court fees or restitution: In some cases, courts may add additional fees related to court processing or damages.
Even without jail time or additional legal action, the total financial burden of a first-time DWI can exceed $2,000, especially when all mandatory programs and license reinstatement steps are included.
Fines for Aggravated or Repeat DWI Offenses
When a DWI charge includes aggravating factors—or if it’s a repeat offense—the fines increase significantly.
Aggravated DWI (First Offense with Enhanced Circumstances)
A DWI may be classified as “aggravated” if it includes any of the following:
- BAC of 0.16% or higher
- Excessive speeding
- Causing an accident with injuries
- Transporting a minor
- Attempting to elude law enforcement
Penalties for aggravated DWI (Class A misdemeanor):
- Minimum fine: $750
- Penalty assessment: 24% surcharge
- Total minimum: $930
- Potential jail time: Minimum of 5 days
In addition to higher fines, aggravated cases usually include longer license suspension periods, more expensive programs, and mandatory installation of an ignition interlock device.
Second DWI Offense
A second DWI conviction within 10 years is also considered a Class A misdemeanor.
Fines for second offense:
- Minimum fine: $750
- Penalty assessment: 24% surcharge
- Total minimum: $930
- Jail time: Mandatory minimum of 17 consecutive days
- Additional costs: Repeat offenders often face higher program fees and longer interlock periods
Third DWI Offense
A third offense is treated as a Class A misdemeanor but carries enhanced penalties and significantly higher overall costs.
- Minimum fine: $750–$2,000
- Jail time: At least 180 days, with part possibly suspended
- Longer suspension: Indefinite license revocation
- Interlock device and other conditions apply
The financial cost of a third offense can exceed $5,000, factoring in incarceration, treatment programs, and long-term insurance penalties.
Felony DWI and Fines
Some DWI charges are elevated to felonies in New Hampshire, including:
- Fourth or subsequent offenses
- DWI resulting in serious bodily injury
Felony-level DWI cases are handled in superior court and result in substantially higher fines:
- Fines start at $1,000 and can exceed $4,000
- Felony penalty assessments are still applied
- Long-term financial impact includes restitution, extended license loss, and loss of income due to incarceration
Felony convictions also lead to permanent criminal records, which can affect employment and financial eligibility for years.
Long-Term Financial Impact of a DWI Conviction
Beyond the court and administrative fines, the long-term costs of a DWI conviction often surpass the immediate penalties. Over time, drivers may experience:
- Higher car insurance rates for 3–5 years
- Loss of job opportunities due to criminal background checks
- Limited access to professional licenses
- Restricted travel or visa complications
- Out-of-pocket expenses for compliance, such as substance evaluations, ongoing interlock monitoring, or missed work
The cumulative cost of a DWI conviction, even if no crash occurred, can easily range from $4,000 to $10,000+ over several years.
Payment Plans and Fine Collection
New Hampshire courts may allow payment plans for those unable to pay the full fine immediately. However:
- The driver must request a plan before the due date
- Interest or administrative fees may be added
- Missing a scheduled payment may result in additional penalties or license hold
Non-payment of fines may also delay license reinstatement and impact probation compliance.
If restitution is ordered for property damage or injury, this is a separate financial obligation that must be paid in full, regardless of ability to pay.
