CALDWELL, Idaho — Idaho State Police (ISP) are investigating a deadly hit-and-run crash that killed a 55-year-old bicyclist in Caldwell on Tuesday, March 18. The incident occurred just after 7 p.m. on the westbound I-84 offramp at mile marker 26 in Canyon County. Authorities are now searching for the driver of a light gray 2004-2006 Acura TL believed to have struck the victim and fled the scene.
According to ISP, the crash unfolded when the bicyclist, a Caldwell resident, was riding eastbound along US20-26. A gray Acura TL, turning west from the I-84 offramp onto US20-26, collided with him. Moments later, a 2013 Ram 2500, also turning westbound, struck the man a second time. The Acura driver sped off, last seen heading south on US20-26 toward Parma. The Ram driver, a 43-year-old Caldwell man, stayed at the scene and was not injured.
The bicyclist suffered critical injuries and died at the location despite wearing a helmet, ISP confirmed. His identity has not been released pending family notification. Emergency responders, including police, fire crews, and paramedics, arrived quickly but could not save him. The intersection of US20-26 and I-84 was closed for about three and a half hours as troopers investigated and cleared debris from the roadway.
ISP says local businesses have provided video footage to aid the investigation, but they still need more specific recordings from the exact time and place of the crash. Troopers are urging anyone who witnessed the incident or has relevant information to contact ISP dispatch at 208-846-7500. They’re particularly interested in dashcam or security camera footage that might show the Acura TL before or after the collision.
The stretch of US20-26 near the I-84 interchange is a busy corridor, connecting Caldwell to nearby towns like Parma and Nampa. It’s a mix of commercial and rural traffic, with cyclists often sharing the road. ISP has not said if speed, weather, or road conditions played a role, but the investigation is ongoing. They’re also looking into whether the Acura driver was aware of the second impact by the Ram.
This marks another tragic loss on Idaho roads, where cyclist safety remains a concern. Last year, Canyon County saw several bike-related crashes, prompting calls for better signage and lane markings. Anyone with tips is asked to call ISP at 208-846-7500 to help identify the suspect vehicle and bring closure to the case.
