First Photos from 'O.C. Housewives' ATV Crash ... Total Disaster Scene

'O.C. Housewives' Vicki Gunvalson and Tamra Barney were way worse off than we initially thought after they rolled an ATV while taping on Saturday.

TMZ obtained these photos and video from the crash scene in Glamis, CA ... where Vicki had to be airlifted to a hospital for treatment. Witnesses on scene tell us she was puking after the accident, and couldn't feel her fingers. Both women complained of neck and back pain, and you can tell from these images ... everyone on scene was concerned about the severity of the injuries.

We're also told Tamra, who was driving the Polaris RZR, had been warned several times by the people training her to slow down.

TMZ broke the story ... both women had to be hospitalized after the accident, which happened while they were shooting for the show.

Both have been released, and we're told they're recovering well.
