Summary:

This report assembles available evidence for the impact of Plainridge Park, MGM Springfield and Encore Boston Harbor on impaired driving in the region, to include complaints (arrests and summonses) for operating under the influence [OUI], OUI-involved crashes, and reports of “last drink” locations from guilty drunk drivers. These findings support the utility of targeted traffic enforcement at key times along local roads and highways leading to and from the casino, as well as expanded public awareness efforts. They also demonstrate the utility of continued data collection of “last drink” reports during adjudication.
