• The diagram assumes the player is right-handed.
• Free relief is allowed for interference by an abnormal course condition (ACC), including an immovable obstruction, when the ball touches or lies in or on the condition (B1), or the condition interferes with the area of intended stance (B2) or swing.
• The nearest point of complete relief for B1 is P1, and is very close to the condition.
• For B2, the nearest point of complete relief is P2, and is farther from the condition as the stance has to be clear of the ACC.
(2) Relief Allowed Anywhere on Course Except When Ball Is in Penalty Area. Relief from interference by an abnormal course condition is allowed under Rule 16.1 only when both:
• The abnormal course condition is on the course (not out of bounds), and
• The ball is anywhere on the course, except in a penalty area (where the player’s only relief is under Rule 17).
(3) No Relief When Clearly Unreasonable. There is no relief under Rule 16.1:
• When playing the ball as it lies is clearly unreasonable because of something from which the player is not allowed to take free relief (such as when a player is unable to make a stroke because of where the ball lies in a bush), or
• When interference exists only because a player chooses a club, type of stance or swing or direction of play that is clearly unreasonable under the circumstances.
See Committee Procedures, Section 8; Model Local Rule F-23 (the Committee may adopt a Local Rule allowing free relief from interference by temporary immovable obstructions on or off the course).
16.1b Relief for Ball in General Area
If a player’s ball is in the general area and there is interference by an abnormal course condition on the course, the player may take free relief by dropping the original ball or another ball in this relief area (see Rule 14.3):
• Reference Point: The nearest point of complete relief in the general area.
• Size of Relief Area Measured from Reference Point: One club-length, but with these limits:
• Limits on Location of Relief Area:
o Must be in the general area,
o Must not be nearer the hole than the reference point, and
o There must be complete relief from all interference by the abnormal course condition.
