Idaho State police investigated a four-vehicle crash Thursday that backed up traffic on Interstate 84 near the Eagle Road exit during rush hour.
Police said Andrew J. Pribek, 28, of Meridian was driving a 2001 Suzuki motorcycle west on I-84 near the Eagle offramp and couldn't stop in time to avoid a crash after encountering traffic that was slowing in front of him.
Pribek ran into the back of a 2007 Ford Expedition driven by Robert D. Osborn, 40, of Blackfoot.
Osborn drove into the back of a 2000 Hyundai Elantra, driven by Debra S. Barnes, 55, of Caldwell.
That impact pushed Barnes into the back of a 2008 Honda Ridgeline pickup, driven by Jayme A. Hoff, 35, of Meridian.
ISP said no one was transported for medical treatment. They said Pribek was wearing a helmet, and all the drivers were wearing seat belts.
The right lane of I-84 was blocked for about an hour and a half.
