The Rules of Flat Track Roller Derby

2 - Skater Positions and Identification

Skater positions refer to the position a skater is playing, from the beginning of one jam until the beginning of the next jam (including the time in between jams). Skaters who did not participate in the prior jam are considered Blockers (see Section 2.1 - Blocker) until the next jam starts, even if they are lining up in a different position. A skater is not limited in the number of positions that skater may play during a game, but is limited to playing one designated position at a time. A maximum of four Blockers and one Jammer from each team are allowed on the track during play; only one of the Blockers may be a Pivot Blocker (see Section 2.2 - Pivot Blocker and Section 2.3 - Jammer).
