What happens when play is suspended in golf?

• Immediate suspension, used for danger: no stroke may be made until play resumes. Playing on means disqualification.
• Normal suspension, for darkness or an unplayable course: a group between holes must stop. A group that has started a hole may stop at once or play out the hole.
• Lightning: a player who reasonably believes there is danger may stop without waiting for the Committee, and must report to it as soon as possible.
• A match: the players may agree to stop for any reason, unless that delays the competition.
• Stopping for any other reason means disqualification.

The ball:

• When play stops, the player may mark and lift the ball.
• When play resumes, the ball, or another ball, is replaced on the spot. Play restarts from where it stopped, even on a later day.
• If the ball or the marker was moved during the stoppage, by anything, it is put back.
• Players must be in position and resume at the time the Committee sets.

Everyone in a competition should play in conditions decided by the Committee, not by each player's own view of the weather. Lightning is the one case where safety cannot wait for an announcement.
