Bus Crash on I-84

PORTLAND, Ore. (AP) -- Lawyers representing a survivor and the estates of three people killed in the tour bus crash last December on I-84 near Pendleton are suing the Oregon Department of Transportation.

The lawsuit says the department was negligent for failing to warn drivers of unsafe conditions, not requiring commercial vehicles to taken another route, not adequately plowing and sanding snow, and failing to equip that stretch of the interstate with barriers strong enough to prevent a bus from leaving the roadway.

ODOT spokesman Patrick Cooney told The Oregonian it doesn't comment on pending litigation.

A total of nine people were killed in the crash and 38 injured.
