OLYMPIA, Wash. (AP) — State regulators have ruled that a Seattle tour company involved in a deadly crash in September can resume operating a limited fleet of amphibious vehicles, under certain conditions.

After a three-hour hearing Monday, the three-member Washington Utilities and Transportation Commission approved a joint stipulation that allows the company to resume operations of its "Truck Duck" vehicles.

"Truck Duck" vehicles have a different manufacturer, chassis and axle system than the "stretch duck" vehicle that swerved into an oncoming charter bus on Sept. 24, killing five international college students.

Under the agreement, Ride the Ducks Seattle must submit a safety plan and have it approved by Jan. 29. If the plan is accepted, the company's safety rating will be upgraded to conditional, contingent on follow up investigations.
