Roller Derby 101

Jacksonville Roller Derby plays flat track roller derby according to the latest rules and clarifications from the Women’s Flat Track Derby Association. See how many JRD skaters you can spot in their Derby 101 videos! The latest ruleset is available at rules.wftda.com.

The objectives of roller derby are relatively simple.  Each team fields one point-scoring skater (“Jammer”) whose objective is to lap as many opposing skaters as they can.

The remaining skaters who aren’t scoring points work both on offense and defense at the same time — to block the opposing Jammer and to clear a path for their own Jammer.

Well-played roller derby requires agility, strength, speed, control, peripheral vision, communication, and teamwork.

About the Game

Common Questions

Are there fights on the track?

Very rarely. The WFTDA rules call for the expulsion of skaters participating in fights, which helps to keep the skaters and referees safe. Fights did occasionally break out on the track in the Gotham Girls’ early seasons, but since then the flat track roller derby game has matured. The skaters now channel their aggression by getting up, dusting themselves off, and legally hitting their foes even harder in the next jam.

Why are there so many referees out there?

Much like in football, the ref squad internally divides areas of responsibility — the front of the pack, the rear of the pack, scoring for one team, scoring for the other team, etc. The refs practice communicating with each other to determine the legality of action on the track.

Do skaters have to wear old-school 'quad' skates?

Yes. Ever since its invention in the 1930s, roller derby has traditionally been a ‘quad’ skate game. Quad roller skates promote control and stability, and their smaller wheel base reduces the chances for skaters to get tripped up on each others’ skates.

The Rules

TIMING

  • Each two-minute play is called a JAM.
  • Between each jam, there are 30 seconds for teams to line up for the next jam.
  • There are two halves in a BOUT. Each half is 30 minutes long and has an unlimited number of jams.
  • Teams may freely substitute players between jams, except for players stuck in the penalty box.

PENALTIES

  • BACK BLOCK: Blocking a skater in their back
  • HIGH BLOCK: Blocking with a helmet, or blocking a skater in their head
  • LOW BLOCK: Tripping, kicking, or blocking with feet or legs
  • FOREARM: Blocking with forearms, hands, or elbows
  • OUT OF PLAY: Blocking while 20 feet ahead of or behind the pack
  • OUT OF BOUNDS: Blocking while out of bounds, or blocking a skater who is out of bounds
  • CUTTING THE TRACK: Skating out of bounds to get around other skaters
  • PACK DESTRUCTION: Intentionally destroying the pack, such as by taking a knee or leaving the track in a way which renders the remaining players ineligible to block
  • ILLEGAL PROCEDURES: False starts, too many skaters on the track

THE PENALTY BOX

  • A penalty costs 30 seconds of jam time in the box, served immediately so long as a seat is available in the box.
  • Refs gesture skaters to the box with a swooping motion of one finger to direct the skater off the track.
  • A jammer in the box is released immediately if the other jammer also lands in the box.

SETUP & SCORING

  • Each team fields five players at a time.
  • Out of those five players, four are BLOCKERS and one is the JAMMER (point scorer).
  • The four blockers from each team line up together between a designated “Pivot Line” and “Jammer Line” marked on the track, to form a PACK, while the two jammers line up behind the Jammer Line.
  • The skater wearing the star on their helmet is the jammer. The skater wearing the stripe on their helmet is called the PIVOT. The pivot is commonly the pack leader and defensive play caller, similar to football’s middle linebacker position.
  • On the whistle, the pack and jammers may begin to engage each other.
  • On the first lap, the jammers earn no points, but the first jammer to legally pass each blocker on the opposing team and clear the pack is called LEAD JAMMER. You can tell if a skater is the Lead Jammer by looking at their designated jammer ref. The jammer ref will point to the jammer and hold their hand up in an “L” shape. The Lead Jammer reserves the right to strategically end the jam before the two minutes are completed by repeatedly gesturing with their hands on their hips. If both jammers commit fouls on their first lap, there is no Lead Jammer in that jam and it will run for the full 2 minutes.
  • Jammers lose Lead Jammer status if they are sent to the penalty box during the jam.
  • After a jammer completes their initial lap, they score 1 point for each opposing skater they pass.
  • Jammers automatically score points against opposing skaters serving in the penalty box.
  • Jammer referees hold up fingers at the conclusion of each lap for points just earned.
