at the nearest point on the goal line to the turnover location, by moving from the turnover location.
The intended thrower, before picking up the disc, may signal the goal line option by fully extending one arm above their head.
The goal line signal can be useful to communicate to all players that the goal line option will be taken.If the signal is made, the thrower must move to the goal line.
However it is a voluntary signal. The intended thrower may still establish the pivot at the goal line even if they do not signal the goal line option.
The defence may ask the intended thrower if they intend to choose the goal line option and it is good spirit to provide a response (via hand signal), however it is not required.
