ELK GROVE -- California Highway Patrol investigators are looking into a three-vehicle crash that happened on Wilton Road Monday morning.
CHP Officer Michael Bradley said a Toyota Corolla was traveling on the wrong side of the road at around 7:15 a.m.
It side-swiped a Camry and an Elk Grove School District Special needs school bus, propelling all vehicles in different directions.
"If you figure the bus was traveling at 40-45 miles per hour, and the vehicles traveling at 50-55, just traveling at that speed and crash forces and everything else, it's going to create this long scene," Officer Bradley said.
There were four students, a special needs attendant, and a driver inside this school bus. The Elk Grove Unified School District said three students attend Joseph Kerr middle school, the other student goes to Elk Grove High School.
Three were transported to hospital with minor injuries, one was picked up by his parents.
CHP said if there are seat belts in the school bus, the law requires them to use it.
Officer Michael Bradley said that is probably what saved the students.
"Luckily it was a side-swipe and not a head-on, where the bus driver was able to recognize that the vehicle was on the wrong side of the road, and make some evasive action. Unfortunately, they could not take control of the bus and it did overturn, but it could have been much worse," Officer Bradley said.
The CHP is now trying to figure out what caused the driver of the Corolla to veer on the wrong side of the road.
"This is a pretty straight and flat roadway, so there is no reason that person should be on the wrong side of the road, unless they were possibly distracted," Officer Bradley said.
