Police are looking for a man spotted "car surfing" on a California highway.
In a video provided to local ABC-owned station KABC, the man appears to dance while hanging off the passenger side of a dark-colored pickup truck for several seconds before he re-enters the car through a window.
The California Highway Patrol told ABC News that the agency is looking for the unknown man. Police stressed the danger of such a stunt, noting that the man could have fallen off the vehicle and into traffic.
Highway Patrol said both the man outside the car and the driver could be facing two infractions: one for what they call unlawful riding, the other for not wearing a seat belt."
Further details on the incident were not immediately available.
