Mandatory minimum penalties for second offense DWI convictions are now bifurcated, with offenders whose offenses arise within two years of the prior DWI conviction subject to a higher minimum jail sentence. Those convicted within the first two years of the prior conviction are now subject to a minimum of thirty consecutive 24-hour periods in the House of Correction, immediately followed by seven days in the Multiple DWI Offender Detention Center (MOP). Those convicted of a second offense DWI where the date of the offense is between two and ten years following the prior conviction face the same minimum of three 24-hour periods in the House of Correction immediately followed by seven days at the MOP facility in Laconia. The license loss for each of these offenses remains at three years. The minimum fine for both offenses has been increased to $750.00, plus penalty assessment of $150.00; the maximum penalty for each offense remains at one year. So far, judges have not seemed willing to accept plea agreements calling for three 24-hour periods in the House of Correction immediately followed by seven days at the MOP facility in Laconia for those defendants whose motor vehicle record shows a prior conviction that is within the two-year period.   

Those convicted of aggravated DWI (other than felony DWI) now face a mandatory jail sentence and must attend the seven-day residential MOP program, even if they have no prior DWI conviction and have never attended an IDIP program. That minimum jail sentence is now three 24-hour periods in the House of Correction immediately followed by seven days at the MOP facility in Laconia. As in the case of second offense DWI, the minimum fine has been increased to $750.00, plus penalty assessment of $150.00. Maximums remain unchanged.
