When trooper arrived on scene they found that three vehicles had crashed causing the far left lane (#1 travel Lane) to be blocked. Police say the driver of a gray BMW was slowing down due to congested traffic in front of her when she was struck in the left rear by a Ford SUV.

The driver and passenger of the Ford SUV and the driver of the Chevy van where transported to Renown Regional Medical Center with claimed injuries. The driver of the BMW was uninjured. The drivers of the Ford and Chevy have been cited for following too close involving an accident. Impairment is not a factor of the accident.
