Police are detouring traffic in the area.

Warrnambool police Acting Sergeant Paul McGovern said the female driver was the only person in the vehicle.

"It appears the vehicle was driving north-west and the driver was distracted and veered off to the right oncoming lane, over-corrected at the shoulder then (the vehicle) rolled," Sergeant McGovern said.

"It came to rest on the roof."

Police continue to investigate the cause.

He said the driver was transported to Warrnambool Base Hospital's emergency department with injuries to her hand as a result of the crash.

Sergeant McGovern said members of the public must drive to the conditions.
