PORTLAND - Lawyers representing a survivor and the estates of three people killed in an Oregon tour bus crash last December are suing the Oregon Department of Transportation.

The lawsuit says the department was negligent for failing to warn drivers of unsafe conditions and not adequately plowing and sanding snow. The lawsuit also faults the department for not requiring commercial vehicles to take another route and for 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 (http://bit.ly/ZL4aYH ) that it doesn't comment on pending litigation.

A total of nine people were killed and 38 injured in the crash on I-84 near Pendleton.
