Just after 3pm, a sweeper crew was working on the left shoulder of I-69 at FM 1314 when a vehicle sideswiped the protection truck and flipped. In doing so the driver also ripped open the fuel tank or the protection truck dumping 150 gallons of diesel on the freeway. Moments later a secondary crash occurred approximately 100-yards behind the first. At this point, 8 vehicles were involved in that crash. some persons were seriously injured. Crews have almost cleared the secondary crash but the first crash needs to be worked in which that driver who sideswiped the protection truck is in very critical condition. The freeway will open to two right lanes shortly.
