An arrest for driving while intoxicated (DWI) in New Hampshire is stressful. This is a serious situation, but understanding the process and your rights can help you navigate this challenging time more effectively. Three things to know to help you gain control over this situation include the following.
#1: What are New Hampshire’s DWI laws?
New Hampshire law prohibits operating a vehicle with a blood alcohol concentration (BAC) of 0.08% or higher. For drivers under 21, the limit is just 0.02% and 0.04% for those with a commercial license. Even if your BAC is below these thresholds, you can still face charges if your ability to drive is impaired by alcohol, drugs or any combination of substances.
#2: What happens after an arrest?
The DWI process in New Hampshire generally moves forward through the following stages:
- You will face an administrative license suspension hearing separate from your criminal case
- You have a short period of time to request a hearing to contest the administrative suspension
- Your criminal case will proceed through the court system independently
These administrative and criminal proceedings run on parallel tracks, which means you must address both aspects of your case. Missing deadlines for the administrative hearing can result in automatic license suspension regardless of the outcome of your criminal case.
#3: What are the possible consequences?
A first-offense DWI in New Hampshire carries significant penalties that can affect multiple aspects of your life. They can vary by county, but penalties generally include:
- A fine ranging from $500 to $2,000
- Possible jail time up to six months (though often suspended for first offenders)
- License suspension for up to one year
- Mandatory completion of an impaired driver education program
- Installation of an ignition interlock device in some cases
Beyond these legal penalties, a DWI conviction can impact your employment, insurance rates and personal reputation. The consequences extend far beyond the courtroom.
Taking action now
The steps you take immediately after your arrest can significantly influence the outcome of your case. Gathering evidence, identifying witnesses and understanding the specific circumstances of your stop are all time-sensitive matters. Many people facing their first DWI charge assume they have no options, but that is not necessarily true. Challenging the traffic stop, questioning the accuracy of testing procedures or negotiating alternative dispositions may all be possibilities depending on your specific situation.
Your future is too important to leave to chance when facing DWI allegations.
