The coaches’ technical area on each side of the halfway line shall be marked by two lines off the field of play and perpendicular to the touchline.  The area shall be as long as the diameter of the center circle. Where possible, the coaches’ technical area shall include two additional lines, with one line parallel to and at least one yard from the touch line, and a second parallel line no more than three yards from the touchline.  

The field shall be marked, where possible, with a spectator control line parallel to the touchline at a distance of at least three yards from the touchline. Coaches and officials should help the assistant referees keep spectators behind the spectator control line and between the top lines of the penalty area.

Spectators shall not be allowed behind the goal lines, with the exception of photographers who have received authorization from the referee, and who shall remain quiet and sufficiently back from the goal lines.
