UPDATE 7:06 a.m.: A big rig rear-ended a trailer truck Friday morning on southbound I-5 near Grapevine Road, according to CHP.
The driver of the big rig has major injuries, CHP said. There was a passenger who was sleeping and CHP isn't aware of his condition.
One big rig was driving faster than the truck in front of him and that's why he rear ended the truck, CHP said. The driver failed to realize truck in front of him was going slow.
Two right lanes are still blocked and CHP estimates it'll be a couple of hours before they are open again.
The other big rig driver was not injured and just complained of pain, CHP said.
