when a player shoots the puck from behind his red line down the ice and goes over the opposing team’s red line (without anyone touching it in between).
so the puck has to go over the 2 red lines in order for it to be icing. Unless it goes into the opposing team’s net, the goal will count.
when there is an icing call, the puck is brought back to the defenders zone (of the team that committed the infraction) for a faceoff.
Yes when a someone sends the puck untouched past 3 lines (blue lines and goal line) and a person from the other team touches it before your team does it brings the faceoff back into your defensive zone.
Unless the rules have changed drastically since the last time I checked, it’s 2 red lines including the mid-line. So it’s basically anywhere from behind center ice. (I hope posting the rules isn’t a Lifnei Iveir on Chukas Hagoyim.)
Any contact between opposing players while pursuing the puck on an icing must be for the sole purpose of playing the puck and not for eliminating the opponent from playing the puck. Unnecessary or dangerous contact could result in penalties being assessed to the offending player.
The puck striking or deflecting off an official does not automatically nullify a potential icing.
