Purpose: Rule 18 covers taking relief under penalty of stroke and distance. When your ball is lost outside a penalty area or comes to rest out of bounds, the required progression of playing from the teeing area to the hole is broken; you must resume that progression by playing again from where the previous stroke was made.
This Rule also covers how and when a provisional ball may be played to save time when your ball in play might have gone out of bounds or be lost outside a penalty area.
At any time, you may take stroke-and-distance relief. Once you put another ball in play under penalty of stroke and distance, your original ball is no longer in play and must not be played. This is true even if your original ball is then found on the course before the end of the three-minute search time.
When Ball is Lost. Your ball is lost if not found in three minutes after you or your caddie begins to search for it. If a ball is found in that time but it is uncertain whether it is your ball:
If you do not identify your ball in that reasonable time, the ball is lost.
When Ball is Out of Bounds. Your ball at rest is out of bounds only when all of it is outside the boundary edge of the course.
If your ball is lost or out of bounds, you must take stroke-and-distance relief by adding one penalty stroke and playing a ball from where the previous stroke was made (see Rule 14.6).

If your ball might be lost outside a penalty area or be out of bounds, to save time you may play another ball provisionally under penalty of stroke and distance.
But if you are aware that the only possible place your original ball could be lost is in a penalty area, a provisional ball is not allowed and a ball played from where the previous stroke was made becomes your ball in play under penalty of stroke and distance.
Before the stroke is made, you must announce that you are going to play a provisional ball.
It is not enough for you only to say that you are playing another ball or are playing again.
You must use the word "provisional" or otherwise clearly indicate that you are playing the ball provisionally under Rule 18.3.
If you did not announce this (even if you intended to play a provisional ball) and played a ball from where the previous stroke was made, that ball is your ball in play under penalty of stroke and distance.
Playing Provisional Ball More Than Once. You may continue to play the provisional ball without it losing its status as a provisional ball so long as it is played from a spot that is the same distance or farther from the hole than where your original ball is estimated to be.
When Provisional Ball Becomes Ball in Play. Your provisional ball becomes your ball in play under penalty of stroke and distance in either of these two cases:

When Provisional Ball Must be Abandoned. When your provisional ball has not yet become your ball in play, it must be abandoned in either of these two cases:
