A Killeen tow truck driver died at Seton Medical Center Thursday after being struck by a minivan just west of the Nola Ruth Bridge on I-14 westbound (formerly known as Highway 190) in Harker Heights around 6:20 a.m.

The victim's identity was not released as of Thursday afternoon, pending notification of his family. But, Harker Heights Police Sergeant Steve Miller said the victim was a vehicle recovery specialist from Goodes Towing.

The man had parked his tow truck, with the emergency lights activated. He was walking to recover a disabled vehicle when he was hit by the minivan, police said. He was transported to the hospital, where he succumbed to his injuries, according to Sgt. Miller.

The Harker Heights Police Department's Accident Reconstruction Team is investigating the crash.

In 2003, Texas implemented a "move over" or "slow down" law that applies to emergency vehicles, including tow trucks. It mandates drivers vacate the lane closest to the emergency vehicle when driving on a highway with multiple lanes going one direction, if they don't intend to slow down. As an alternative, the law requires drivers to slow to at least 20 miles per hour below the posted speed limit -- assuming the regular speed limit is more than 25 miles per hour. If the posted speed limit is below 25 miles per hour, drivers are still required to slow down by at least five miles per hour when passing emergency vehicles in Texas.
