It's one of the most dangerous stunts you can pull with a car. A Mid-State teenager has been recovering from a severe head injury after falling from the trunk of a moving vehicle.
Some said they think he was car surfing. Two women found him bleeding in the road and said he's lucky to be alive.
They came to his aid in the middle of an intersection in a quiet Hermitage neighborhood.
"He was bleeding and face down on the ground and not moving at all," said Sierra Drake.
She and Brianin Turner were the first on the scene after the McGavock student was thrown from the trunk of a car.
"We saw them drive past and he was sitting on the back of the car, and we were just saying something bad is going to happen," said Drake.
"He had to brace himself because when the guy stopped it threw him back," said Turner.
This may have been a type of so-called "car surfing." There have been different styles, and police said they're all exceedingly dangerous.
In some cases, a person balances outside a speeding truck before falling to the pavement, and in other cases, skate boarders surf alongside a moving car.
Drake and Turner said they've seen it happen too often.
"Messing around... just being crazy," said Drake.
They called 911, and their actions may have saved the teen's life.
However, twelve years ago, another McGavock teen did not survive.
Shawn Nipper was thrown while surfing on the roof of a moving car at Two Rivers Park.
"He was thrown off because the car either braked or slowed down," said his sister, Leah Nipper, at the time.
Shawn died from his head injuries.
Many may wonder who's doing this type of thing, and the answer has typically been males ages 15 to 19. They have made up about 70 percent of so-called "car surfers."
Statistics have also shown that this activity, for whatever reason, has been happening mostly in the south.
Officials with the Metro Nashville Police Department responded to the recent accident scene in Hermitage.
The person behind the wheel was cited for reckless driving. The injured teen was recovering in the hospital.
