A demolition derby is a grandstand event in which drivers deliberately crash a field of cars into one another until only one still runs under its own power, and it belongs to the entertainment side of a fair's program rather than the agricultural side. Unlike pulling or harness racing, a derby has no roots in farm work, and it typically appears at fairs large enough to run a full grandstand schedule across multiple evenings rather than at a single-day town or Grange fair. It sits inside the same competitions figure as judged livestock and craft classes, 30 of the 98 events in this directory, even though the skill being judged, essentially controlled destruction, has nothing to do with agriculture.
Also known as: demo derby, car crash derby.
