HIXSON, HAMILTON COUNTY, TN (WRCB) -- Hamilton County Sheriff's Office is investigating a motorcycle crash that sent two teens to the hospital.

Authorities were called to 7400 Gates Road around 2 pm Saturday after a motorcycle accident was reported.

Deputies found two juvenile males with serious injuries.

An eyewitness told deputies he saw the motorcycle speeding. When it reached the crest of the hill, the motorcycle went airborne.

Investigators say speed was a factor, and they believe the lack of experience the driver had with motorcycles may have played into the crash.

The 15 year-old male driver suffered serious injuries and was transported by Life Force to T.C. Thompson Children's Hospital. The passenger, a 14 year-old male, was taken to the hospital by ambulance.

The investigation is on-going and being handled by the Hamilton County Sheriff's Office Traffic Division.
