The Rules of Flat Track Roller Derby

3.6 - Helmet Covers

3.6.1 - Teams must have two sets of different helmet covers available at a bout. A team’s helmet cover colors must meet the definition of high contrast beyond a reasonable doubt or the Head Referee shall request that the team use helmet covers that meet the definition. The Jammer’s and/or Pivot’s helmet cover colors are of high contrast if there is a large degree of visual difference between the star/stripe color and the base color of the cover such that the star/stripe color stands out from the base color.

3.6.2 - A team’s helmet covers are easily identifiable if they can be readily distinguished by officials, other skaters, and fans from the helmets of the Blockers on the track.

3.6.3 - All helmet covers used by one team must be of the same color scheme (e.g., a team cannot use black base and yellow star/stripe in one jam then yellow base and black stripe in the next jam, or mix color schemes in the same jam).

3.6.4 - An opposing team may challenge the use of a team’s helmet covers if they feel there could be confusion in distinguishing between the Jammer star/Pivot stripe and the base color of the helmet cover compared to the base color and design elements of the team’s helmets.

3.6.4.1 - A number on a helmet cannot be confused for a star; however, if the number is surrounded by logos or any design a team may challenge the use of that helmet cover.

3.6.4.2 - In the event of a challenge by the opposing team that meets the above standard, the Head Referee must require use of the alternate color helmet covers. If a team’s helmet cover colors are not identical but very similar, the Head Referee may enforce the helmet cover switch, but is not required to.
