Arizona Department of Public Safety spokesman Bart Graves says three students on the Peoria Unified School District bus and the drivers of two other vehicles were being treated for minor injuries.
He says the school bus driver told officers that his vehicle's brakes didn't work when he came off the Loop 101 freeway. Graves says the bus struck a pickup stopped at the off-ramp's light and the truck then hit a sedan also stopped at the light.
Graves says another bus took the 32 students on the bus who weren't injured to their destination, Sunnyside Elementary School.
