Roughly 15 people were hospitalized after a memorial motorcycle ride collided with multiple vehicles on Interstate 84 in Caldwell on October 3, 2026, shutting down all westbound lanes for four hours while emergency crews cleared the scene.
A large memorial ride turned into an emergency response zone on Saturday afternoon when a crash involving 25 motorcycles and seven vehicles blocked westbound lanes of Interstate 84. The incident took place at around noon near milepost 28, close to 10th Avenue in Caldwell, according to updates from the Idaho State Police.
Emergency responders deployed a life flight helicopter alongside multiple ground ambulances to manage the casualties. A total of 15 individuals sustained injuries severe enough to require transport to local hospitals, with victims arriving via helicopter, ambulance, and personal vehicles.

The scale of the wreckage brought traffic along a primary regional corridor to a complete halt. All westbound lanes between exit 29 and exit 27 were shut down for four hours while troopers and emergency personnel worked the scene. A photograph shared by Code Red Towing captured several damaged motorcycles surrounded by emergency vehicles along the interstate.
The Idaho Transportation Department utilized its 511 system to direct motorists away from the congestion, urging drivers to seek alternate routes through the Treasure Valley corridor, which links Boise, Meridian, Nampa, and Caldwell. By evening, authorities confirmed that the blocked stretch of the interstate had been cleared and all westbound lanes were reopened to traffic.
