Golf Penalty Areas: Red vs Yellow Stakes and Every Relief Option

A penalty area is any body of water on the course, plus any other part of the course the Committee defines as one, usually marked with red or yellow stakes or lines. If your ball is in one you have a choice: play it as it lies, which costs nothing, or take relief outside the area for one penalty stroke. Yellow gives you two relief options and red gives you three, because only red allows lateral relief within two club-lengths of where the ball last crossed the edge. Water that nobody has marked counts as red.

That is Rule 17 of the 2023 Rules of Golf, which remains the current edition as of 2 October 2026; The R&A has said the next edition will be published on 1 January 2028.

What counts as a penalty area

The definition starts with water. Every body of water on the course is a penalty area whether or not anyone has marked it: seas, lakes, ponds, rivers, ditches, surface drainage ditches and other open watercourses, even when they are dry. On top of that, the Committee may define other ground as a penalty area, and the definition mentions features such as a beach or desert area forming an edge. The Committee may also declare a usually-dry drainage ditch to be general area instead.

How the edge works matters more than most golfers realise:

• Stakes: the edge runs between the outside points of the stakes at ground level, and the stakes themselves are inside the area. Penalty-area stakes are obstructions, not boundary objects.
• Lines: the edge is the outside edge of the painted line, so the line is part of the area.
• Up and down: the edge extends above and below the ground. A ball resting in a branch over the water is in the penalty area.

Your ball is in the area when any part of it touches the ground or anything else inside the edge, or sits above the edge or any part of the area (Rule 17.1a). Touching the line is enough.

Why a course chooses yellow

The Committee Procedures that accompany the Rules say most penalty areas should be marked red, precisely so players have the extra lateral option. Yellow is for holes where the carry is the point. The example given is a stream crossing the front of a green: if it were red, a ball that cleared the stream and then rolled back in could be dropped on the green side under lateral relief, and the carry would stop mattering. Marked yellow, that player must go back.

The same guidance asks Committees marking an area yellow to make sure back-on-the-line relief is always possible, or to add a dropping zone, and allows them to mark everything red for simplicity. Where an area changes colour, red and yellow stakes should sit next to each other at the transition point. Stakes with green tops mark a no play zone inside a penalty area, and Committees are told to avoid red or yellow when marking boundaries.

So the colour is information about the hole. Yellow at the front of a green tells you the Committee treats the carry as part of the hole's challenge and has chosen not to let a ball that fails it be dropped on the far side.

In, or only probably in?

If you can see your ball in the area, Rule 17.1a settles it. If you cannot find it, the standard is "known or virtually certain": either conclusive evidence, such as someone watching it splash, or all reasonably available information showing it is at least 95% likely to be in there. Only information found during the three-minute search counts.

Fall short of that and the ball is simply lost, which means stroke and distance under Rule 18 instead. That is why a provisional ball is allowed when a shot might be in a penalty area but might also be lost somewhere else. And once you put another ball in play under Rule 17, the original is out of play even if someone finds it inside the three minutes.

Playing it as it lies

Rule 17.1b treats a ball in a penalty area exactly like one in the general area: there are no special restrictions on how you play it. You may also stand inside a penalty area to play a ball that lies outside it. The single exception is a no play zone within the area, from which you must take relief.

The three relief options, step by step

Stroke and distance: yellow or red

Play again from where you made the previous stroke (Rule 14.6). From the teeing area you may tee the ball anywhere in it. From the general area, a bunker or a penalty area you drop within one club-length of that spot, in the same area of the course and no nearer the hole.

Back-on-the-line: yellow or red

Find point X, the estimated point where the ball last crossed the edge. Drop on a line that runs from the hole through X and keeps going back, as far as you like. The spot where the ball first touches the ground creates a relief area one club-length in every direction, no nearer the hole than X, outside that penalty area, and in the same area of the course the ball first touched.

The line is strict. A clarification of the Rules gives the example of a player who drops almost a club-length to the side of the line: that is a wrong place even if the ball rolls onto the line, and the ball must be dropped again.

Lateral relief: red only

Take X as the reference point and drop within two club-lengths of it, no nearer the hole and outside that penalty area. If more than one area of the course lies within those two club-lengths, the ball must come to rest in the same area it first touched when dropped. A club-length means your longest club other than the putter. For players who use a wheeled mobility device, Rule 25 extends lateral relief to four club-lengths.
