Free Consultation
A felony Driving Under the Influence (DUI) charge in New Hampshire involves significantly more serious allegations than a standard DUI offense. These cases may arise from prior convictions, injury-related incidents, or other aggravating circumstances that increase the severity of potential penalties.
Because felony DUI charges can carry substantial incarceration exposure and long-term consequences, early legal strategy and careful evaluation of the evidence are especially important.
What Is a Felony DUI in New Hampshire?
In New Hampshire, DUI charges may be prosecuted at the felony level when certain conditions are present. These may include prior qualifying DUI convictions within the applicable lookback period or allegations involving injury to another person.
Whether a case qualifies as a felony and what penalties may apply often depend on prior record history and the circumstances surrounding the incident.
Possible Penalties for Felony DUI
Potential consequences of a felony DUI conviction may include:
- substantial incarceration exposure
- extended driver’s license suspension
- fines and court costs
- alcohol or drug treatment requirements
- ignition interlock device requirements following reinstatement eligibility
- probation supervision following release
- long-term criminal record consequences
The outcome of a case depends on the facts of the incident, prior record history, and how the evidence develops during court proceedings.
Prior Conviction Qualification Issues
Whether earlier DUI cases legally qualify as predicate offenses can be an important issue in felony DUI prosecutions.
Careful review of prior court records and disposition history may affect how a case is classified and what penalties may apply.
Injury-Related Felony DUI Allegations
Some felony DUI cases involve allegations that another person was injured during the incident. These cases often require detailed review of accident reconstruction evidence, medical documentation, and witness observations.
Careful evaluation of both impairment evidence and causation issues can affect how these cases proceed.
Administrative License Suspension Consequences
Drivers charged with felony DUI may also face Administrative License Suspension through the New Hampshire Division of Motor Vehicles following arrest.
Because administrative consequences can begin before the criminal case is resolved, early evaluation of available options can be important after an arrest.
Evidence Issues in Felony DUI Cases
Felony DUI cases often involve detailed examination of multiple forms of evidence. Defense strategy may include reviewing:
- the legality of the traffic stop
- roadside investigation procedures
- field sobriety testing
- breath or blood testing procedures
- accident reconstruction findings
- witness statements and officer observations
Careful evaluation of these issues can affect how a case proceeds.
