The rig fell onto the turnpike below and burst into flames.Police officers working a lane closure nearby were quickly on scene. Police say the officers and stopping motorists tried to rescue the driver from the truck cab. They were forced back as flames consumed the cab.The crash shut down the westbound lanes of I-30 and both directions of SH 161 for several hours Saturday.“There are a lot of variables that could have mixed into this that could have made it more of a tragedy than it is," said Det. Lyle Gensler, with the Grand Prairie Police Department. "We're very thankful that when the truck veered off of I-30 it didn't hit any other cars, carrying with it to 161. So it is very unfortunate that the driver died at the scene, but it's very fortunate that others lived through this horrific incident.”Late Saturday night, police told NBC DFW that the truck is owned by B&M Trucking of Gallatin, Tenn.The truck was transporting a load of ceramic tile to San Diego, Calif., at the time of the crash and, according to police, was filled to capacity.
