Two people were injured just after 1 p.m. Thursday in a single-car collision on Interstate 5 south, about four miles south of Woodland.
Merly D. Delfin, 52, of Vancouver, B.C., was driving her 2008 Toyota Matrix south on I-5 around Milepost 16 when she drifted into the left shoulder. She overcorrected, swerved across all three traffic lanes and struck the guard rail on the right side of the road.
Delfin and her passenger, Nilia A. Deleon, 47, of Vancouver, B.C., were both injured and transported to Legacy Salmon Creek Medical Center.
Delfin was cited for driving with wheels off the roadway.
