The Monroe Police Department is part of the Southern Fairfield County Traffic Unit. As of Thursday, Bridgeport, Fairfield, Trumbull, Easton, Stratford and Monroe Police Departments entered into an agreement allowing the agencies to work in a coordinated effort to help reduce traffic crashes and enhance traffic safety. The joint venture will allow them to share resources, participate in training opportunities, and further enhance communications that cross jurisdictional lines. Officers from these six departments may be working in each others towns during pre-planned traffic details with a certain objective. It ranges from seatbelt enforcement to DUI checkpoints.
