CASTLE ROCK, Colo. -- A crash occurred near exit 184 off of Interstate 25 in Castle Rock Sunday afternoon.
A semi tractor with a fully loaded flat-bed trailer going southbound off the exit ramp failed to stop and collided with six other vehicles, pushing many through the intersection.
The semi took two of the cars downhill into a commercial parking lot and hit the back of a liquor store.
All of the occupants of the vehicles were extricated and transported to local hospitals as necessary. CSP says the extrication did take a while.
Seven people have injuries that are not life-threatening. One person -- a 49-year-old man from Castle Rock -- has injuries that are possibly life-threatening, CSP said.
CSP is continuing to investigate the crash.
There were several road closures in the area. They reopened about 6:15 p.m.

Records from the U.S. Department of Transportation show the company National Wood Products Inc. owns the semi. The company has an office in Denver but is based in Salt Lake City.
Records show the company has a total of 30 vehicles in its fleet. In the past two years the company has gone through 67 inspections with a total of 58 vehicle violations.
Information from the DOT shows at least 14 of those violations were brake-related. The company also has six unsafe driving violations in the same two-year period including speeding and not wearing a seat belt.
The violations are for the entire fleet, not the specific truck involved in Sunday's crash. It's unknown whether that truck had any violations.
