Ball interfering with play

If another player reasonably believes that your ball might interfere with their play:

The other player may require you to mark the spot and lift your ball, which must not be cleaned (except when you lifted it from the putting green).
If you do not mark the spot before lifting your ball, or you clean the lifted ball when not allowed, you get one penalty stroke.
In stroke play only, if you are required to lift your ball under this Rule, you may choose to play first instead.

You are not allowed to lift your ball under this Rule based only on your belief that it might interfere with another player’s play. If you lift your ball when not required to do so by another player (except when lifting the ball on the putting green), you get one penalty stroke.
