Authorities say the three 19-year-old males who sneaked onto a dirt racetrack in Jefferson, South Dakota to turn some laps have been released from the hospital.
The trio were injured when their car rolled Sunday afternoon.
Union County deputies and the South Dakota Highway Patrol responded to the crash at the Park Jefferson Speedway.
Authorities say two of the three males were thrown from the car when it went out of control and rolled, and all three were injured.
Union County Sheriff Dan Limoges says the men are not being identified as the owner of the track has declined to press charges against them.
