A truck fire on Highway 190 Monday evening halted traffic and proved a challenge for firefighters.

Flames erupted in the cabin of an 18-wheeler in the eastbound lane near the Willow Spring exit around 2 p.m. The driver of the truck was pulled out by a Fort Hood soldier and taken to Metroplex Hospital to be treated for smoke inhalation. The fire eventually caused the fuel tanks in the vehicle to explode, sending thick black plumes of smoke into the air.

The cause of the fire is under investigation.
