Relief - Back on a Line

Back on a line (Updated for 2023 Rules)

Can be used when the ball is:

Relief is taken from a reference point, either

a) the point where the ball crossed into a Penalty Area or where it went out of bounds

b) where the ball was lying in the General Area if declared unplayable. 

... then back on a line away from the hole, through that point.

Players often mistakenly assume it is the line the ball was travelling along.

Note that ... 

Back on a line - ball entered Penalty Area (or out of bounds)

Back on a Line - ball declared unplayable (position of the ball is the reference point)
