New Hampshire Ignition Interlock Laws

Have you been arrested for a DWI in New Hampshire? You are not alone. In 2008 alone, over 4,000 people were arrested for Driving While Intoxicated, while close to 100 people lost their lives due to alcohol related automobile accidents. As the state’s lawmakers and law enforcement agencies grasp with this growing problem and how to best deal with it, new DWI laws are constantly being proposed and enacted.

One such law involves the use of Ignition Interlock Devices (IID) for DUI offenders. An IID is a small alcohol breath-testing device that is attached to the ignition of the DUI offenders car. The IID prevents the vehicle from starting unless a sober breath sample is not blown into the devices nozzle. Random additional breath samples will be required while the car is in motion to prevent a friend from starting the vehicle.

Ignition interlock devices have proven to be very effective at stopping DUI recidivism. Statistics have shown that the most dangerous Dui offenders show a pattern of repeating their behavior. In fact, many drivers involved in fatal alcohol-impaired-driving crashes have been arrested previously for driving while intoxicated (DWI). In 2007, drivers with a blood alcohol concentration (BAC) of .08 grams per deciliter or higher in fatal crashes were eight times more likely to have a prior conviction for driving while impaired than were drivers with no alcohol (NHTSA, 2008a).

New Hampshire Ignition Interlock Laws state that: (an) Interlock device is required on any vehicle registered to a person who drives after a suspension or revocation resulting from a DWI offense. DWI offenders with aggravating circumstances or multiple DWI offenses on their record may be required to install an ignition interlock device on the vehicles owned or regularly used for 6 months to 2 years following license reinstatement.

“Aggrivating circumstances” are most often defined as exceedingly high BAC (blood alcohol contents), or a DUI case in which people are seriously injured due to the alcohol related crash.

New Hampshire hopes that the continued vigilant enforcement of these statutes will help reduce DWIs in the state. The latest studies have also found that the use of Ignition Interlock Devices helps recidivism among DUI offenders. Research shows that ignition interlocks, while installed on an offender’s vehicle, reduce recidivism among both first-time and repeat DWI offenders. More than 10 evaluations of ignition interlock programs have reported reductions in recidivism rang­ing from 50 to 90 percent, with an average reduction of 64 percent while the interlock is installed on the vehicle
