For the past year, the National Transportation Safety Board has been investigating a fatal crash involving a Grey Hound bus. The crash occurred in the northbound lanes of U.S. Highway 101 in San Jose on Jan. 19, 2016.
Early reports found that the bus had struck a stationary crash attenuator adjacent to a carpool lane. The bus then road up onto a concrete barrier before overturning onto its side roughly 65 feet from the initial point of impact.
The NTSB now believes the crash occurred because the California Department of Transportation (Caltrans) failed to properly mark the gore – the paved area between the main highway and the exit lane – with stripes or chevrons.
According to NTSB, the driver of the bus, Gary Bonslater, 58, thought he was in the left-hand exit lane when he struck an unmarked crash attenuator in the gore.
In a statement, NTSB chairwoman T. Bella Dinh-Zarr commented, “This crash did not have to happen because the barrier that the bus hit should have been visisble, even in the bad weather, but it was not.
Dinh-Zarr added that deaths and injuries could have been further prevented if all occupants had worn their seatbelts.
