Passengers Caroline Conrad, 22, and Terrance Freeman, 24, were taken to Strong Memorial Hospital after their car rolled over.
Ontario County Sheriff's Office say that their car was on Melvin Hill Road when the driver swerved to avoid hitting a deer. That caused the driver to lose control, cross into the northbound lane and roll over.
Conrad was transported by ambulance and Freeman was transported by Mercy Flight. Both had neck injuries.
All other passengers were treated at the scene.
