The Putnam County Sheriff and Carmel Police are participating in a special enforcement effort to crackdown on impaired driving this St. Patrick's Day weekend.  Sheriff deputies and Carmel Police will be out in force through Sunday.  This weekend's crackdown is one of many statewide enforcement initiatives promoted by the New York State STOP-DWI Association with additional funding from the Governor’s Traffic Safety Committee. The Campaign also targets Memorial Day, 4th of July and Labor Day Weekend, Halloween, the Holiday Season throughout December and the Super Bowl weekend.
