The difference between golf red vs yellow stakes comes down to one extra option. Both colors mark a penalty area. From either one you may play the ball as it lies with no penalty, or take relief for one penalty stroke. A yellow penalty area gives you two relief options: stroke and distance, or back-on-the-line. A red penalty area gives you both of those plus lateral relief, a drop within two club-lengths of where your ball last crossed the edge, no nearer the hole. That is Rule 17.1d of the current 2023 Rules of Golf.
Everything else people argue about on the course follows from that one difference, and from a single question: where did the ball last cross the edge? Both are covered below, with the Rule number for each point so you can check it yourself.
Which Rules This Is Based On
The R&A's Rules Hub lists the 2023 Rules of Golf as the current edition (read October 2, 2026), with its most recent clarifications dated July 1, 2026. Those clarifications update the 2023 edition rather than replace it, and the USGA and The R&A publish the same Rules, so this applies on any course playing by them. The relief options themselves are quoted from Rule 17 in the R&A's online Rules of Golf, read the same day. If you want to go straight to the primary text instead of any summary, our guide on where to read the official Rules of Golf shows where it lives.
What Red and Yellow Stakes Actually Mark
Since 2019 the Rules have not used the term "water hazard." The replacement is the penalty area, and the purpose statement of Rule 17 describes penalty areas as "bodies of water or other areas defined by the Committee where a ball is often lost or unable to be played." That last part matters: a penalty area does not have to hold water. A course can mark a ravine, a desert wash or a thick patch of native vegetation the same way.
Under Rule 2.2, a penalty area is one of the five defined areas of the course, alongside the general area, the teeing area, bunkers and the putting green. The color of the stakes or lines tells you which version of Rule 17 relief applies. Under the Definitions in the Rules, a penalty area the Committee has not marked with a color is treated as red.
White stakes are a different thing entirely. They mark out of bounds, not a penalty area, and none of the relief options in this article apply to them.
Golf Red vs Yellow Stakes: The Side-by-Side Table
| Your option | Yellow penalty area | Red penalty area | Rule | Penalty |
|---|---|---|---|---|
| Play the ball as it lies | Yes | Yes | 17.1b | None |
| Stroke and distance (replay from your last stroke) | Yes | Yes | 17.1d(1) | 1 stroke |
| Back-on-the-line drop | Yes | Yes | 17.1d(2) | 1 stroke |
| Lateral drop within two club-lengths | No | Yes | 17.1d(3) | 1 stroke |
| Drop on the opposite side, same distance from the hole | No | Only if the course adopts Model Local Rule B-2 | Local Rule | 1 stroke |
The quick version: yellow means "go back," red means "go back or go sideways."
The Relief Options in Plain Terms
Stroke and distance (red and yellow)
You play the original ball or another ball from where you made the previous stroke, adding one penalty stroke. It is always available, and it is the option people forget, even though it is sometimes the best one. If your previous shot was from the tee, you can tee it up again.
Back-on-the-line (red and yellow)
Find the estimated point where your ball last crossed the edge of the penalty area. Keep that point between the hole and the spot where you drop, and go back as far as you like on that line. Rule 17.1d(2) sets the relief area at one club-length in any direction from where the dropped ball first touches the ground. The relief area cannot be nearer the hole than the crossing point and cannot be in the same penalty area.
Lateral relief (red only)
Rule 17.1d(3) sets the reference point as "the estimated point where the original ball last crossed the edge of the red penalty area." From there you have two club-lengths, not nearer the hole, and the drop can be anywhere on the course except in that same penalty area.
A club-length is measured with the longest club you have for the round other than your putter, which for most golfers is the driver. If you want to know how long your own driver is, the golf club spec sheet, translated shows where length is listed.
Why a Course Marks One Area Yellow
If red gives golfers more options, why does yellow exist at all? The answer is in the R&A's Committee Procedures guidance on course marking (read October 2, 2026), which starts from red as the default:
"Most penalty areas should be marked red to give players the additional option of lateral relief. However, where part of the challenge of the hole is to carry over a penalty area such as a stream that crosses the front of the putting green and there is a good chance that a ball that carries over the stream could fall back into it, the Committee may decide to mark the penalty area as yellow."
Picture what lateral relief would do on that hole. Your approach clears the stream, lands on the far bank and spins back into the water. The point where it last crossed the edge is now on the green side. With red stakes you could drop within two club-lengths of that point and chip on, as if you had carried the hazard. Yellow takes that away. Your choices are back-on-the-line, which keeps the stream in front of you, or replaying the shot.
The same guidance tells Committees that when an area is marked yellow they "should ensure that a player will always be able to drop back-on-the-line under Rule 17.1d(2) or consider adding a dropping zone for the penalty area." So if you see a dropping zone near a yellow area, that is why it is there.
The Question That Decides Everything: Where Did It Cross?
Most red-versus-yellow mistakes are not about color at all. They are about the reference point. Both back-on-the-line and lateral relief start from where the ball last crossed the edge, not where it splashed and not where it is sitting now.
Those can be very different spots. A ball that slices across the corner of a long red area beside the fairway may cross the edge well behind where it finally lands in the water. Measuring two club-lengths from the splash, instead of from the crossing point, usually puts you in the wrong place, and playing from a wrong place carries the general penalty under Rule 14.7a.
Two practical habits help. Watch the ball all the way, and agree on the crossing point with your playing partners before anyone walks off. The Rules accept an estimate here, so a reasonable judgment made in good faith is what is expected.
The other condition is certainty. Rule 17.1c lets you take penalty area relief for a ball you cannot find only if it is "known or virtually certain" that the ball came to rest in the penalty area. If that is not the case and the ball is lost, Rule 17.1c sends you to stroke-and-distance relief under Rule 18.2 instead. "It probably went in the water" is not enough when there is thick rough around the edge where it could also be hiding.
Playing It From Inside the Penalty Area
You are never forced to take relief. Rule 17.1b lets you play the ball as it lies, without penalty, under the same Rules that apply in the general area. That was a real change in 2019: the old hazard restrictions on touching the ground or water with your club no longer apply inside a penalty area.
What you lose inside a penalty area is relief under other Rules. Rule 17.3 says that when your ball is in a penalty area there is no relief for an abnormal course condition, an embedded ball or an unplayable ball. You cannot declare a ball unplayable in a red or yellow area and use Rule 19. Your options are the Rule 17 options above.
Can You Move the Stakes?
Usually, yes, with one important exception. Red and yellow stakes are treated as obstructions, so if they are movable you may remove one that interferes with your swing or stance under Rule 15.2, whether your ball is inside the penalty area or outside it. A Committee can declare them immovable, in which case you leave them alone.
White out-of-bounds stakes are the opposite. They are boundary objects, and moving one to improve the conditions for your stroke breaches Rule 8.1a, with the general penalty: two strokes in stroke play, loss of the hole in match play.
Common Mistakes With Red and Yellow Stakes
- Taking a lateral drop from a yellow area. Lateral relief is red only. From yellow, you go back on the line or replay.
- Measuring from the splash. The reference point is where the ball last crossed the edge.
- Dropping nearer the hole. Both lateral and back-on-the-line relief forbid it.
- Declaring unplayable inside the penalty area. Rule 17.3 rules it out.
- Assuming you can drop across the water. Opposite-side relief exists only where the course has adopted Model Local Rule B-2. Our explainer on how local rules relate to the Rules of Golf covers how to find out what a course has adopted.
- Treating "probably in the water" as certain. Without known or virtual certainty, a lost ball is a lost ball.
What This Article Cannot Settle for You
The Rules set the options, but the Committee sets the course. Which areas are red, which are yellow, whether there is a dropping zone and whether opposite-side relief is allowed all depend on how a particular course is marked and which Local Rules it has adopted. The scorecard, a notice in the clubhouse or a question at the pro shop will tell you; this article cannot.
This guide is written from the published Rules text, not from time on a course. For a disputed ruling in a competition, the Committee's decision is the one that counts.
Frequently Asked Questions
What is the difference between red and yellow stakes in golf?
Both mark a penalty area with a one-stroke penalty for relief. Yellow gives you stroke and distance or back-on-the-line relief. Red adds a third option: a lateral drop within two club-lengths of where the ball last crossed the edge, no nearer the hole.
Can you drop on the other side of a red penalty area?
Only if the course has adopted Model Local Rule B-2, which allows lateral relief on the opposite side at an equal distance from the hole. Without that Local Rule, the drop has to be measured from the point where the ball last crossed the edge.
What if a penalty area has no stakes or lines?
Under the Definitions in the Rules of Golf, a penalty area whose color the Committee has not marked is treated as red, which means lateral relief is available.
Is it a penalty to touch the water or ground with my club in a penalty area?
Not in itself. Since 2019, Rule 17.1b lets you play a ball in a penalty area under the same Rules that apply in the general area.
Do I measure from where my ball is in the water?
No. Both back-on-the-line and lateral relief use the estimated point where the ball last crossed the edge of the penalty area, which may be a long way from where it ended up.
