LE MARS, Iowa (KTIV) — A collision between a semi and a northwest Iowa school bus Monday morning sent a number of people to a hospital. According to the Iowa State Patrol, the crash happened at about 7:20 a.m. at the intersection of County Road K64 and 120th Street, which is located between the towns of Oyens and Carnes.

The state patrol says 61-year-old Raymond Holbrook was driving a Le Mars Community School bus west on 120th and failed to yield the right of way to a semi. That semi, driven by 67-year-old Brian Bachmann, struck the side of the bus, and both vehicles ended up in a ditch.

Le Mars Superintendent Steve Webner says four students were on the bus at the time of the crash. “We can confirm there were non-critical, non-life threatening injuries, and they were taken to the hospital,” Webner said in an email to KTIV. “The district is cooperating with law enforcement officials with the investigation in this matter.”

Webner said not all four students were taken to the hospital, while the state patrol says the drivers of the semi and school bus were taken to a Le Mars hospital.
