What was initially believed to be a pedestrian crash was really the aftermath of a domestic incident, according to Riviera Beach police.
It happened around 9 a.m. on Barack Obama Highway.
The windshield of a black Nissan had visible damage when police arrived.
A man damaged the front of the car and then jumped on the hood and fell off, investigators now say.
He suffered traumatic injuries and was taken to an area hospital for treatment.
The man's condition has not been released.
