A 31-year-old woman suffered a critical head injury after she rolled her car while driving south on Interstate 15 near St. George on Saturday, the Utah Highway Patrol said.
Holly R. Ventura, of Murray, was driving south in a Nissan Maxima at high speeds at about 6:40 p.m. when she failed to negotiate a curve and rolled, said UHP Cpl. Todd Johnson.
Ventura was about 25 miles north of St. George when she went off the roadway and into the center divider, before over-correcting back to the right. The car shot across two lanes of traffic and into brush and rocks on the right shoulder before rolling at least 300 feet and coming to rest upside down, Johnson said.
