The CHP Officer was heading to a traffic accident. When he tried to pass a big rig on the off-ramp ... the truck driver veered into him ... causing him to crash on the side of the road.
The big rig driver took off as the patrol car became covered in flames which created a small brush fire. The officer escaped.
Witnesses in the area say ammunition in the car started going off during the fire.
CHP Officers caught up with the big rig driver about 45 minutes later. He faces "hit and run" charges.
