NICOLAUS -- Investigators looked into what caused a big rig to veer into oncoming traffic and slam into a pickup truck around 6 Monday morning in Nicolaus.
"And they hit driver to driver side," said Yuba-Sutter CHP public information officer Jodie Beck. "The impact killed the driver and the passenger behind the driver."
Moments after that collision another truck crashed into the back of the big rig.
"The big rig continued northbound out of control into the southbound lanes and another truck hit the back of that big rig," Beck said.
Two people inside the landscaping truck died on the scene but everyone else is expected to be OK.
Now, CHP officials are trying to figure out why the driver of the big rig crossed over the median.
Locals say the stretch of Highway 99 and Sacramento Avenue has become a problem area. The owner of a nearby fruit stand told FOX40 he has been seeing crashes at the intersection far too often.
"You hear the honking all the time. The slamming on the brakes," said Steve Lendl.
Lendl said he has seen at least four crashes in front of his fruit stand in the past two years.
"Really bad ones where they’ve come off the side of the road. They’ve been through our fences three different times," he said. "They keep propelling themselves off the levee here. It’s just been really dangerous and it continues to happen, you know?"
He said he just replaced part of his fence along Highway 99 after another crash about a month ago on Labor Day weekend.
"You see continuously there’s accidents here all the time and I don’t understand why there’s not a stoplight here. I think that’s unsafe. Something ... they need to do something," Lendl said.
FOX40 reached out to the landscaping company that owns the pickup truck involved in the deadly crash. They sent a statement that says in part, "Two BrightView team members lost their lives early this morning in a traffic accident near Sacramento. BrightView extends its deepest condolences to the victims, family and friends."
CHP officials say they don’t think alcohol or drugs played a factor in the crash and everyone involved was wearing a seatbelt.
