DUI/DWI Charges & Consequences

Alcohol and car keys - NH DWI laws

You can be charged with drunk driving if your blood alcohol concentration (BAC) measures .08 percent or more, or if the arresting police officer observes that your driving has been impaired to any degree (even if your BAC is less than the legal limit). Aside from alcohol impairment, any type of drug in your system that impairs your driving as measured through your blood can lead to an arrest as well. These drugs can include street drugs, prescription drugs, or over-the-counter drugs. For instance, while marijuana is legal for recreational use in Massachusetts, it is still illegal to drive while under its influence.

Under New Hampshire DUI Law, a first time DUI conviction will be punished with a Class B misdemeanor.

A Class B misdemeanor is punishable by:

  • A fine up to $1,000
  • Driver's license revocation for up to 9 months
  • Mandatory impaired driver intervention program that must be completed within 45 days of the conviction

In New Hampshire, you will have 30 days from the date of your arrest to challenge the state’s automatic license suspension by filing for an administrative hearing. Our Portsmouth DUI/DWI defense lawyer can assist you with this to fight for your driving privileges as well as fully investigate your arrest for flaws, inconsistencies, and other factors that can work in your defense.

DWI Probation

If you have been convicted of DWI, the judge may place you on probation which reduces jail time. Probation may be granted after five days if it is a second offense, 14 days if the offense was within the last two years, or after 30 days if it was a third DWI offense. If probation is granted, you may be required to complete an alcohol and drug evaluation as well as treatment recommended by the Impaired Driver Car Management Program (IDCMP).

Other requirements may include:

  • Random testing
  • Inpatient and outpatient treatment
  • Alcohol and drug monitoring

Aggravated DWIs in New Hampshire

Under New Hampshire DWI law, a DWI is considered to be “aggravated” if it involves:

  • A passenger under 16 years old
  • Excessive speeding
  • A BAC level of 0.16% or higher
  • Bodily injury
  • Running from the police

Aggravated DWI carries more severe penalties. It is considered to be a class A misdemeanor and the penalties can include monetary fines of $750 up to $2,000 and five days up to one year in jail. If the DWI included bodily injury, the charge may be a class B felony, making the penalties increase to monetary fines of $1,000 to $4,000 and 14 days to seven years in jail. If convicted of an aggravated DWI, your driver’s license will be suspended for 18 months up to two years. You may be able to get the suspension period reduced if you participate in the IDCMP.

Sleep Driving

Sleep medications like Ambien and Lunesta have become popular in the last few years. Unfortunately, the use of these medications has resulted in an increase in what is commonly known as “sleep driving.” The FDA defined this condition as “driving while not fully awake after ingestion of a sedative-hypnotic product, with no memory of the event.” This growing danger has caused hundreds of people to suffer DUI and DWI Ambien arrests every year. If you are facing such an arrest, it is critical that you seek experienced legal help as soon as possible.
