New Hampshire First Offense DUI Laws

New Hampshire DUI

In the State of New Hampshire, it is illegal to operate a motor vehicle when you are under the influence of alcohol. If you are caught driving with a blood alcohol content (BAC) of 0.08 or higher, you will be charged with a DUI.

New Hampshire has an implied consent law, which means that by driving in New Hampshire, you are agreeing to submit to a blood or breath alcohol test if asked to so. Refusing to submit to a test carries heavy penalties.

If you have been arrested for a first offense refusing to submit or a first offense DUI, you will want to contact a qualified and experienced DUI lawyer as soon as possible.

New Hampshire DUI law is complicated, and you want to have an expert on your side, working for you.

New Hampshire First Offense DUI Penalties:

A New Hampshire DUI offense carries two separate sets of penalties: administrative and criminal.

When you are arrested for a first offense DUI, you will automatically receive an Administrative License Suspension for 6 months. If you are then also convicted in court, your driver's license may also be revoked by the judge, for 9 months to 2 years. However, even if you receive two suspensions, you will only have to serve the longer of the two.

Before your driver's license will be reinstated you will need to show proof of an SR22 insurance filing. You can obtain an SR22 insurance policy and filing by entering your zip code below and completing the simple form on the following page:

Aggravating Factors:

Factors that could cause your first offense DUI to be considered an "aggravated DUI" include:

  1. Driving more than 30 mph over the speed limit.
  2. Eluding law enforcement (speeding up, turning off headlights, etc.)
  3. Having a child under the age of 16 in the vehicle.
  4. Causing an accident that results in bodily injury to yourself or someone else.

An aggravated first offense DUI for reasons 1, 2, and 3 carries additional penalties, including:

  • $750 fine
  • 3 days to 1 year in jail
  • Mandatory ignition interlock

If your aggravating factor is causing serious bodily injury, then your penalties could include:

  • $1000 to $4000 fine
  • 14 days to 7 years in jail
  • Mandatory ignition interlock 

New Hampshire First Offense DUI and Ignition Interlock:

New Hampshire does have an ignition interlock program for repeat DUI offenders. However, if this is your first DUI offense, and there were no aggravating factors, it is unlikely that you will be required to install an ignition interlock device.

New Hampshire and SR22 Insurance:

SR22 insurance is proof of future financial responsibility. The State of New Hampshire does not require everyone to have their vehicles fully insured; however, if the State considers you a high risk driver, that rule changes. If you lose your license because of a DUI, the State will require you to carry auto insurance. To prove to the State that you are fully insured, you must file an SR22 form, which is provided by your insurance company. SR22 insurance can be expensive, so you want to make sure that you compare the most competitive rates. You can do that by entering your zip code here:
