The Official Rules of Golf appear on the About.com Golf site courtesy of the USGA, are used with permission, and may not be reprinted without the permission of the USGA.

Introduction

This section provides guidelines on the manner in which the game of golf should be played. If they are followed, all players will gain maximum enjoyment from the game. The overriding principle is that consideration should be shown to others on the course at all times.

The Spirit of the Game

Unlike many sports, golf is played, for the most part, without the supervision of a referee or umpire. The game relies on the integrity of the individual to show consideration for other players and to abide by the Rules. All players should conduct themselves in a disciplined manner, demonstrating courtesy and sportsmanship at all times, irrespective of how competitive they maybe. This is the spirit of the game of golf.

Safety

Players should ensure that no one is standing close by or in a position to be hit by the club, the ball or any stones, pebbles, twigs or the like when they make a stroke or practice swing.

Players should not play until the players in front are out of range.

Players should always alert greenstaff nearby or ahead when they are about to make a stroke that might endanger them.

If a player plays a ball in a direction where there is a danger of hitting someone, he should immediately shout a warning. The traditional word of warning in such situation is "fore".

Consideration for Other Players

No Disturbance or Distraction
Players should always show consideration for other players on the course and should not disturb their play by moving, talking or making unnecessary noise.

Players should ensure that any electronic device taken onto the course does not distract other players.

On the teeing ground, a player should not tee his ball until it is his turn to play.

Players should not stand close to or directly behind the ball, or directly behind the hole, when a player is about to play.

On the Putting Green
On the putting green, players should not stand on another player's line of putt or when he is making a stroke, cast a shadow over his line of putt.

Players should remain on or close to the putting green until all other players in the group have holed out.

Scoring
In stroke play, a player who is acting as a marker should, if necessary, on the way to the next tee, check the score with the player concerned and record it.

Pace of Play

Play at Good Pace and Keep Up
Players should play at a good pace. The Committee may establish pace of play guidelines that all players should follow.

It is a group's responsibility to keep up with the group in front. If it loses a clear hole and it is delaying the group behind, it should invite the group behind to play through, irrespective of the number of players in that group. Where a group has not lost a clear hole, but it is apparent that the group behind can play faster, it should invite the faster moving group to play through.

Be Ready to Play
Players should be ready to play as soon as it is their turn to play. When playing on or near the putting green, they should leave their bags or carts in such a position as will enable quick movement off the green and towards the next tee. When the play of a hole has been completed, players should immediately leave the putting green.

Lost Ball
If a player believes his ball may be lost outside a water hazard or is out of bounds, to save time, he should play a provisional ball.

Players searching for a ball should signal the players in the group behind them to play through as soon as it becomes apparent that the ball will not easily be found. They should not search for five minutes before doing so. Having allowed the group behind to play through, they should not continue play until that group has passed and is out of range.

Priority on the Course

Unless otherwise determined by the Committee, priority on the course is determined by a group's pace of play. Any group playing a whole round is entitled to pass a group playing a shorter round. The term "group" includes a single player.
