A rollover crash on southbound Interstate 5 about 5 p.m. Saturday in Tacoma that injured four people was caused by an unsafe lane change, the State Patrol said Sunday.
A 42-year-old Tacoma woman driving a black 2001 Ford Explorer crossed all lanes of traffic trying to take the South 72nd Street exit, was hit by a 2005 silver Toyota Camry right at the exit and rolled, troopers said.
The 42-year-old was taken to St. Joseph Medical Center, as was one of her passengers, a 45-year-old Connecticut woman. The other passenger of the Explorer, a 10-year-old Connecticut girl, was taken to Mary Bridge Children's Hospital.
The 53-year-old Tacoma woman driving the Camry was taken to St. Clare Hospital in Lakewood.
Trooper Guy Gill said Saturday that no injuries appeared life-threatening.
There were indications that the causing driver may have been impaired, Gill said, which was still being investigated Sunday.
