As is the tradition, on that day the car was carrying cheering students.
According to the lawsuit filing, as the Ramblin' Wreck turned left from Techwood Drive onto Ferst Drive at 10-15 mph, the railing Brown had grasped broke, throwing him to the asphalt.
Brown's head slammed onto a concrete curb and he had to be hospitalized for four days, according to the suit. The court filing did not describe specific injuries but said he continues to endure pain from his fall.
Brown declined to comment on the suit on Thursday.
The suit does not ask for specific damages, only what a jury decides.
