According to the lawsuit, state transportation officials failed to post warning signs, had a road design that left little room for error and included no rumble strip to warn drivers they were getting close to the edge, unpaved shoulder was too deep and soft, requiring the driver to steer harder to get back onto the road after passing through a too-narrow buffer zone. It had been repaved the day before, creating a dangerous contrast with the rough shoulder, the lawsuit said.
The lawsuit seeks an unspecified amount in damages to make up for lost wages, medical bills, and emotional suffering.
After carrying out its investigation, the NTSB found a lack of safety standards for bus roofs and windows contributed to the death toll. The report ruled out intoxication or speeding as possible caused for the crash.
