In the first accident, the father was driving his daughter, son and a friend shortly before 4 a.m. Monday morning in the eastbound lanes of US 290 just before FM 362.

The father fell asleep at the wheel, and the vehicle went airborne, flipping in the air before landing right-side-up. When the father realized his daughter was thrown from the car, he went to find her; that’s when he was hit by another vehicle.

Both were Life-Flighted to Memorial Hermann Hospital in critical condition.

The other two passengers had minor injuries; the friend, who was sitting in the front seat, told authorities he was wearing a seatbelt. It is unclear if anyone else in the car was.
