Our team follows 12U youth girls lacrosse rules set forth by USA Lacrosse. Officials use these rules for officiating local youth lacrosse games.
A good video that covers the basic rules for our game, and the official 2017 USLacrosse rules “interpretation” video applicable to our team is below. It’s long but covers some crucial information that helps both players and spectators understand what’s going on. Our team plays a full field, 11 v 11 plus goalkeepers. Full-field is larger than a football in both width and length. Yes, that’s a lot of running. Also, note “restraining violations” at 11:00 minutes in the video. Three restraining lines divide the field into two sections based on ball possession. This outlines lacrosse offsides and how the restraining lines dictate player position and count on the field.
