Dolly Parton 911 -- 'The Driver Is Trapped In the Car'

TMZ has obtained the 911 call made by a bystander moments after Dolly Parton was involved in a car accident in Nashville yesterday.

During the call, the male witness says he saw the car Dolly was riding in (a Nissan) get t-boned by a Mitsubishi.

The witness says the driver of Dolly's car, the singer's longtime friend Judy Ogle, was trapped in the driver's seat and needed help to get her out of the car.

The witness never identifies Dolly by name -- and says that no one appears to be in grave danger.
