The crash on westbound Interstate 84 near exit 35 in Nampa was reported at about 6:30 p.m. Thursday, according to Idaho State Police.
Police say Jack Gore, a 56-year-old from Ogden, Utah, was driving a loaded semi truck west on the interstate. Traffic ahead of him began to slow due to a motorist on the side of the road, but cars slowed faster than he expected.
Gore told police that he tried to change lanes to go around the vehicles ahead of him, but he was unable due to heavy traffic. His vehicle rear-ended a Saturn Ion driven by Timothy Hernandez, a 23-year-old Nampa man.
The impact of the collision caused Hernandez's vehicle to hit a GMC Sierra in front of it. The Sierra was driven by Danny Hilliard, a 44-year-old Caldwell man.
Everyone involved was wearing a seat belt; no airbags deployed. Hernandez was transported to St. Alphonsus Regional Medical Center in Nampa by private vehicle.
The right lane of travel was blocked for more than two hours and it will continue to be blocked until crews on scene get the semi removed.
Idaho State Police is investigating. No information was immediately available on if Gore was cited or charged.
