Flat Track Roller Derby Rules
Basics of play
Flat track roller derby is played by two teams of five members simultaneously skating counterclockwise on a flat track. Each team designates a scoring player (the “jammer”); the other four members are “blockers.” One blocker can be designated as a “pivot” – a blocker allowed to become a jammer in the course of play. The jammer wears a helmet cover bearing two stars; the pivot wears a striped cover; the remaining members’ helmets are uncovered.
The bout is played in 2 halves of 30 minutes. Point scoring occurs during “jams”: plays that last up to 2 minutes. During a jam, points are scored when a jammer on laps members of the opposing team. Each team’s blockers use body contact, changing positions, and other tactics to assist its jammer to score while hindering the opposing team’s jammer. Certain types of blocks and other play are violations; referees call penalties and require violators to serve time in a penalty box.
