The collision on Highway 99 near Culliton Creek left one woman dead and three people injured.

A southbound vehicle lost control and drove into oncoming traffic, and struck a limousine travelling north.

The southbound vehicle then rotated back into the southbound lane and struck a school bus carrying students from Surrey, B.C.
