On January 19, 2016, about 6:37 a.m., a 2014 Motor Coach Industries International, Inc., D4505 motorcoach, operated by Greyhound Lines, Inc., and occupied by a driver and 21 passengers, was traveling north on US Highway 101 (US-101), in San Jose, California. The weather conditions were dark, with moderate-to-heavy rain and reported winds from the east-southeast at 20 mph.
At the US-101 and State Route 85 (SR-85) interchange, the bus moved to the left and entered a 990-foot-long unmarked gore area. The gore separates the US-101 lanes from the left exit high-occupancy-vehicle lane for SR-85. A crash attenuator with a missing retroreflective object marker was positioned at the end of the gore in advance of a concrete barrier. The bus driver maintained the vehicle’s path through the gore and collided with the crash attenuator and the concrete barrier.
Following the impact, the bus traveled another 65 feet, rolled 90 degrees, and came to rest on its right side atop the concrete barrier, straddling two lanes of traffic. As a result of the crash, two passengers were ejected and died, and the driver and 13 passengers were injured.
