Le Bus operates a fleet of 130 motor coaches. All of the crashes that the company's buses are involved in show up in the report, regardless of who was at fault.
The crash drove a large auger on the construction truck through the front of the bus and into the driver's seat and Asiata, who suffered "massive chest trauma," according to UHP Cpl. Todd Johnson.
Four passengers were taken to the hospital, one a woman who last listed in critical condition Tuesday. Johnson said two victims suffered serious but non-life-threatening injuries, while a pregnant woman was transported to the hospital as a precaution when she experienced contractions.
Johnson did not have updates to the four people's conditions as of Wednesday afternoon.
Le Bus, the federal safety administration and UHP are all investigating the crash, along with help from the Utah Department of Transportation. The truck that the bus crashed into had been working on a cable barrier project for UDOT.
A federal investigator met with Le Bus on Tuesday, said UDOT spokesman John Gleason.
The UDOT health and safety policies outline how heavy equipment trucks should have hazard lights, beacons or some form of flashing lights on if they are traveling under the speed limit, Gleason said. However, that policy is for UDOT vehicles and, as of Wednesday evening, it was unclear if the same policy applies to contractors.
It remains to be seen whether the construction truck in this case had flashing lights on, Gleason said. For some reason, the vehicle began to slow down prior to the turn-around center median, according to UHP.
Marissa Padilla, spokeswoman for the federal safety administration, could not comment on any details since the investigation is ongoing.
