NTSB: Lack of roadway markings led to deadly Calif. bus crash
Inadequate highway markings caused a Jan. 19, 2016 Greyhound bus crash in San Jose, California that killed two passengers and injured 13 others, according to a National Transportation Safety Board (NTSB) investigation.
The NTSB determined that the bus struck a crash attenuator - which was not properly marked with a reflective sign - rode up a barrier, rolled onto its right side, and came to rest atop the barrier with its undercarriage facing traffic.
