Law Enforcement agencies in Putnam County are participating in a special enforcement effort to crack down on impaired driving this holiday weekend. This traditionally is one of the busiest travel times of the year, and Sheriff Robert Langley says more people on the roadways means the potential for more crashes. In a combined effort to stop impaired driving, prevent injuries and save lives law enforcement officers across New York State will take to the roads today through Sunday. Research shows that high-visibility enforcement can reduce impaired driving fatalities by as much as 20 percent. The Statewide STOP-DWI Crackdown Campaign will also target the Holiday Season in December.
