TULSA COUNTY, Oklahoma - None of the six students on a Sand Springs school bus involved in a crash Thursday morning were injured, according to the OHP.

The Oklahoma Highway Patrol says the students ranged in age from 11 to 15.  

The 7:43 a.m. crash involving the bus and two cars happened on Highway 412 just east of 177th West Avenue.

Troopers said all three vehicles were eastbound when a 2013 Toyota Corolla, driven by Crystal Jackson, 44, of Terlton attempted to slow down, but instead hit the gas, striking the rear of a 2013 Toyota Corolla, driven by Julie Earsom, 48, of Jennings.    The OHP says that caused Earsom's car to hit the rear of the bus driven by 74-year-old Nena Dunn.

Earsom was taken to a Tulsa hospital where she was treated and released.
