A motorist trying to squeeze his way between a car and a pickup heading east on Interstate 84 east of Broadway Avenue struck both vehicles and forced all three of them off the roadway.
The driver of one of the cars, Deborah Bowman, 31, of Nampa, was injured when her 2006 Chevrolet HHR ran off the right shoulder of the freeway and rolled. She was taken by ambulance to St. Alphonsus Medical Center, where she was treated and released, a hospital spokeswoman said.
Bowman was headed east in the slow lane at about 12:40 p.m. Next to her in the fast lane was a 2011 Dodge Ram 3500 pickup driven by Jose A. Vera, 25, of Jerome, pulling a trailer.
A third vehicle, a 2009 Volkswagen Rabbit driven by Zachary Hoekstra, 26, of Idaho Falls, tried to pass between both vehicles, according to a report from the Idaho State Police. The Rabbit struck Bowman's car, then collided with the pickup and struck the car a second time.
Bowman's car went off the right shoulder and then rolled. The pickup and the Rabbit went off the left shoulder into the median.
One eastbound lane was closed for about an hour as crews worked to clear the scene.
No citations or arrests were immediately reported. The incident is under investigation by the ISP.
