Taken from a collision report by a Washington State Patrol trooper:

Chelsea Harmon, a Port Orchard 20-year-old, was injured Monday in a rollover crash 8.5 miles east of Cle Elum.

Harmon was driving her white, 1998 Ford Contour westbound on Interstate 90, when the vehicle left the roadway to the right, then overcorrected to the left.

It crossed both lanes of traffic, left the roadway to the left, rolled and came to a rest with its tires in the median.

An aid unit took Harmon to Kittitas Valley Community Hospital, and Washington State Patrol troopers charged her with improper lane travel, which allegedly caused the rollover.
