The driver told Eyewitness News he picked up the cars at the Port of Houston. He planned to drive them to Wisconsin when all of a sudden, his lights cut out and he smelled smoke on the freeway. He said he tried to put out the flames with a fire extinguisher when he pulled over, but was unsuccessful.
Tow truck crews arrived just before 5am to haul the big rig away.
No one was hurt. There were no other vehicles involved.
