IDAHO, On January 15, 2012, at approximately 9:16 am, the Idaho State Police responded to a vehicle fire southbound on I15 near milepost 27, approximately 3 miles north of the Malad summit. A semi hauling a load of straw caught fire, and was completely engulfed. The vehicle fire started a grass fire, which burned approximately one acre of brush on the side of the interstate. Both lanes of travel were blocked for approximately forty minutes, and the interstate was reduced to one lane for approximately four and a half hours. Traffic was let through intermittently, as the wind was shifting and blowing debris back across the interstate. No one was injured in this fire, and the driver was not cited. Master Corporal Sellers was assisted at the scene by Corporal Stouse with the Idaho State Police, Bannock County Sheriff's Office, Bannock County Fire Department, Bannock County Search and Rescue, the Downey Fire Department, and the Idaho Transportation Department. This fire is still under investigation by Master Corporal Sellers.
