Post 4 troopers led the Kentucky State Police West Region in arrests for driving under the influence during the first month of 2013.
The West Region includes eight post areas, which cover a total of 64 counties. Of those counties, Post 4 serves eight, including Hardin and LaRue.
Norman Chaffins, spokesman of the Elizabethtown post, said troopers arrested 47 impaired drivers in January. The second ranked post made 39 DUI arrests, he said.
Those arrests include drunken and drugged drivers, Chaffins said.
