GIDDINGS, Texas — Three children were killed in a crash Wednesday afternoon on U.S. 77, five miles south of Giddings, and another died as a result of injuries sustained in the crash.

The crash occurred around 3:40 p.m. Wednesday.

A Peterbilt truck towing a Drag Master was driving southbound on U.S. 77 and lost control, traveling into the northbound lanes. A second Peterbilt truck towing a Drag Master was also traveling southbound on U.S. 77.

A Nissan Pathfinder was traveling northbound and moved to the right to avoid hitting the Peterbilt that had lost control. The Pathfinder traveled off the roadway for a short distance before overcorrecting to the left, traveling across all northbound lanes into the southbound lane and hitting the second Peterbilt truck.
