"We kicked up our enforcement for the entire month. We already took dozens of drunk drivers off the roads, and we're only half done," said Major James Carpenter, South Dakota Highway Patrol.
By the time the New Year arrives, the South Dakota Highway Patrol will have tallied nearly 50 sobriety checkpoints and more than 30 saturation patrols.
"Our mission here is not to arrest as many people as we can. Our mission is to keep our roads safe. We are letting the public know we're enhancing enforcement, so they'll think twice about drinking and driving," said Major Carpenter.
Counties included in the 3D enforcement are Beadle, Bennett, Brookings, Brown, Charles Mix, Clark, Clay, Custer, Davison, Day, Edmunds, Fall River, Hughes, Jerauld, Lake, Lawrence, Lincoln, Lyman, Marshall, McPherson, Meade, Mellette, Minnehaha, Moody, Pennington, Roberts, Sanborn, Stanley, Sully, Tripp, Union, Walworth and Yankton.
In 2005, four people died in traffic crashes in South Dakota during the Christmas holiday.
