Putnam County Sheriff Deputies and Carmel Police Officers will participate in a special enforcement effort to crack down on impaired driving this weekend. The stepped up patrols will be in place from Friday through Monday, Super Bowl Weekend. Sheriff Robert Langley says high-visibility enforcement can reduce impaired driving fatalities by as much as 20 percent. He added that sobriety checkpoints play a key part in raising awareness about the problem. The Sheriff's Department has a mobile app called “Have a Plan” and it's meant for people to find a safe ride home. The Statewide STOP-DWI Crackdown Campaign also targets St. Patrick’s Day, Memorial Day, 4th of July and Labor Day Weekend, Halloween and the Holiday Season in December.
