Question:
If a Blocker can line up behind the Jammer line can said blocker hit the opposing Jammer before the Jammer starting whistle?

Answer:
No.  The Blocker is out of play and any blocking is therefore illegal.  In addition, Blockers will receive a minor penalty for lining up anywhere on the track not between the Jammer and Pivot lines.   

Question:
Is there any limit to how far behind the Jammer line a Jammer may line up?

Answer:
There is no limit–the Jammer may line up anywhere on the track, excluding between the Jammer and Pivot lines, without accruing penalties.  If the Jammer is lined up right in front of the Pivot line she still has to skate all the way around and catch up to the rear of the Pack before her “initial pass” will start.

Question:
What is the penalty for standing in the wrong place on the track when a jam starts?

Answer:
Jammers will receive a minor penalty for lining up on the track between the Jammer and Pivot lines. Blockers will receive a minor penalty for lining up anywhere on the track not between the Jammer and Pivot lines.

Question:

Must Players line up exactly how the Pre-Jam Formation Diagram illustrates?

Answer:

Pivots should line-up directly behind the Pivot line and all other Blockers in two rows. However, strict adherence to the Pre-Jam Formation diagram is not vitally important–if a Blocker or Pivot is skating into their position, on the track between the Jammer and Pivot lines, no penalty should be given.
