What is an Ignition Interlock Device for NH DUI Charges and How Does It Work?

An IID is a mechanism that operates much like a Car Breathalyzer and is installed in DUI offenders vehicles and potentially any other vehicles registered in their name. This NH DUI Interlock device is used to deter offenders from drinking and driving. This is done by requiring drivers to provide a breath sample into the device before the vehicle can be started – should the sample have a BAC of above the pre-programmed threshold, the device prevents the vehicle from starting. In the state of New Hampshire, this threshold is general calibrated at 0.02 percent.

Most of the Ignition Interlock devices in New Hampshire are programmed to require random retests after the vehicle has started – this is meant to prevent a third party from providing the breath sample when offenders are in fact driving the car. Whenever prompted, drivers need to provide another breath sample – should the sample have a blood alcohol content level of above the pre-programmed threshold, the Interlock device does not turn the engine off, but a signal is given to stop the vehicle, an alarm sounds until the vehicle is turned off, and the event is logged and stored in the device’s memory.

When is Using an Ignition Interlock Device Required in the State of New Hampshire?

Courts in the state of New Hampshire have authorized the installation of an Ignition Interlock device as a condition for DUI offenders to have their driving privileges reinstated. While the installation and maintenance of this IID can be ordered for any offender, specific offenders, such as those charged and convicted of Aggravated DUI or repeat DUI offenders, will likely be ordered to use this device. Often times, the use of an Interlock is required for a person to get their driver’s license reinstated for a period of six months to two years following their license reinstatement.

Who Pays for the Cost of the Ignition Interlock Device in NH?

In almost all DUI cases where offenders are ordered to use and install an Ignition Interlock in NH, those who are convicted of the DUI or DWI charges are responsible for paying all the costs associated with installing and maintaining the device. People who have to complete this process should expect to pay upwards of $100 to have the Interlock device installed as well as between $75 and $120 a month to lease the device. It is important to keep in mind these costs are just rough estimates, and prices vary between NH Ignition Interlock providers – some providers even offer free IID installation.

What is the Process of Getting an Ignition Interlock Device in New Hampshire?

After a person is ordered to get a DUI Interlock as a means to have their New Hampshire driving privileges reinstated, they likely have a window of time in which they need to lease the IID, have it installed, and provide proof to the court that the process has been completed. Individuals then need to contact a state approved Ignition Interlock device provider to obtain the device – the state of New Hampshire has approved IID providers across the state, and a full list of these providers can be located on the New Hampshire DMV website.

When the device has been leased from a New Hampshire state approved provider, the DUI/DWI Interlock also needs to be professionally installed in order to remain within the state’s guidelines for IID use. After the entire process is completed, it is not uncommon for offenders to provide proof to either the court, their probation officer, the judge, and/or the DMV that the device has been leased from an approved provider and installed professionally. Most often, this proof comes in the form of the lease agreement or installation receipt.
