There's a dangerous trend happening on America's roads. Many teens and young adults are playing a game called "Car Surfing."

It's already proven to have deadly consequences. A 21-year-old New Mexico woman just became the seventh person to die while car surfing this year in the United States.

Videos of the dangerous game can be found online. The goal is to act like they're on a surfboard when they're really on the top or hood of a moving car.

Police say even at speeds of five miles an hour, someone can be killed if they're thrown from a moving car.

A recent CDC study found car surfing is a major problem in the South and Midwest, where 75 percent of those treated for car-surfing injuries reside.

In most car-surfing cases that end in injuries or death this year,  drivers have faced charges ranging from reckless driving to manslaughter.
