Three people inside a pickup truck were killed when it was hit by a tractor-trailer while stopped in lanes of the eastbound 91 Freeway in Buena Park on Friday morning, Feb. 7, authorities said.
California Highway Patrol officers began receiving calls about the crash just before 4 a.m., just east of Valley View Street, CHP spokesman Officer Duane Graham said.
All three people inside the pickup truck were believed to be in their 20s and 30s, Graham said.
The GMC pickup was involved in what officers believe was a solo crash that disabled the truck in the lanes, Graham said, but the circumstances of that crash were not yet known.
The pickup was then hit by the tractor-trailer, Graham said.
It was not yet known whether wet road conditions, speed, or driving under the influence may have played a factor in the initial crash, the spokesman said.
