SOMERSET — Now through Sept. 3, Somerset police will partner with the Massachusetts State Police and hundreds of other police departments to conduct extra traffic enforcement focused on arresting impaired drivers as part of a “Drunk Driving, Over the Limit, Under Arrest” Mobilization. State and local police will conduct sobriety checkpoints throughout the mobilization. The Executive Office of Public Safety and Security has provided $1,150,000 in federal grant funding for this initiative for both enforcement and a public education campaign.
