A 34-year-old Goulburn woman is in a serious but stable condition following a crash on Monday.
The woman was driving north on the Hume Highway at about 4pm when she lost control of her Kia Sorento, 8km south of the Federal Highway junction.
The car rolled several times, landing in a paddock the right way up.
Motorists helped her until emergency services arrived, police said.
She was transported to Canberra Hospital with minor chest injuries.
Traffic was not disrupted.
