Demolition Derby

Various classes of vehicles have competitions staged on figure 8 shaped tracks. Bump To Pass Figure eights are also quite popular as they involve less prep work from the usual figure eight racer which usually can also race as an oval track street stock. Demolition derby vehicles - especially school buses - often compete on figure 8 tracks. The best known figure 8 track in the US is Riverhead Raceway in Riverhead, New York.
Monster truck racing
Junked vehicles are also destroyed for entertainment at monster truck competitions, so demolition derbies are often staged there as a preliminary event. The rise in popularity of monster truck competitions, beginning in the 1980s is sometimes cited as coming at the expense of demolition derby popularity. While derbies featured mostly local amateur talent, monster trucks popularized a new set of competitors and vehicles recognized nationwide by fans.
