Putnam County Sheriff Robert Langley and Putnam County police agencies will participate in special efforts to bring awareness to the dangers of impaired driving this long holiday weekend.  Langley says millions will hit the roads eager to spend time with family and friends, making it one of the busiest travel times of the year.  He noted that more people on the roadways means the potential for more vehicle crashes. In a combined effort to bring awareness to the dangers of impaired driving, prevent injuries and save lives law enforcement officers across New York State and STOP-DWI programs will be participating in special engagement efforts. The statewide STOP-DWI High Visibility Engagement Campaign starts today and will end on Sunday.  The initiative includes a mobile app called “Have a Plan” and helps people find a safe ride home.
