MELBOURNE, Fla. (AP) - Police say a man who was "messed up" on medication and texting while driving caused a six-vehicle pileup on U.S. 192 in Melbourne.

The pickup driven by 27-year-old Brigham Reed Clark crashed into a Chrysler PT Cruiser about 4 p.m. Tuesday, starting a chain-reaction pileup. Seven people were injured and the highway was closed for more than two hours.

Florida Highway Patrol spokesman Channing Taylor says Clark was charged with driving under the influence.

Taylor says Clark had taken some "serious" medication before the accident.

The accident report indicated Clark looked down to text and when he looked up, he hit the PT Cruiser.
