Penalty Area

A penalty area is a marked part of a golf course, typically containing water, from which a player can take relief for a one-stroke penalty under Rule 17 of the Rules of Golf. Penalty areas are identified by red or yellow stakes or lines.

What is a penalty area in golf?

A penalty area is the part of the course where the Rules of Golf assume a ball will often be unrecoverable or unplayable. Under Rule 17, a player whose ball comes to rest in a penalty area can either play it as it lies or drop a ball elsewhere for a one-stroke penalty.

Penalty areas are most often bodies of water. The USGA and R&A definition lists any sea, lake, pond, river, ditch, surface drainage ditch, or other open watercourse, even when the area contains no water at the time of play. The Committee in charge of a course also has the discretion to designate non-water areas as penalty areas. Dense rough, deserts, thick jungle, or rocky scree fields are all common examples of courses around the world.

This concept replaced the older term “water hazard” when the Rules of Golf were rewritten for 2019. The change broadened the category and reflected how courses outside traditional parkland settings actually play.

Of the five areas of the course defined by the Rules (the teeing area, the general area, bunkers, the putting green, and penalty areas), the penalty area is the one most often associated with a stroke being added to the scorecard.

Red vs. yellow penalty areas

Every penalty area is marked one of two colors, and the color determines what relief options the player has. Yellow penalty areas allow two relief options. Red penalty areas allow those same two, plus a third option: lateral relief within two club-lengths of where the ball last crossed the edge.

Yellow penalty areas are traditionally used when the area lies in front of the line of play, and carrying the ball over it is part of the test. A stream running across the front of a green is the classic example. Red penalty areas are typically used along the side of a hole, where lateral relief makes the round flow more naturally.

The USGA and R&A both recommend that most penalty areas be marked red. The reasoning, according to guidance published by the R&A, is to give players more flexibility and to reduce confusion about which options apply. Any penalty area not marked or indicated in either color is treated as red by default.

When a ball counts as being in a penalty area

Per Rule 17.1a, a ball is in a penalty area when any part of it lies on or touches the ground or anything else inside the edge of the area, or sits above any part of the penalty area. A ball resting on a leaf or twig overhanging the water still counts as being inside.

The edge itself is defined by stakes (the line between the outside points at ground level) or by a painted line on the ground (the outside edge of the line). Some courses use both, in which case the line defines the edge, and the stakes act as visual markers from a distance.

If a player cannot locate the ball, but it is known or virtually certain that it came to rest in the penalty area, relief under Rule 17 is available. If that standard is not met, the ball must be treated as lost, and the player must take stroke-and-distance relief under Rule 18.

Relief options under Rule 17

Once a ball is in a penalty area, the player has four ways to continue:

Play it as it lies. No penalty. Since the 2019 rule changes, this is more practical than it used to be, because grounding the club and removing loose impediments are now allowed in a penalty area.
Stroke-and-distance relief. One penalty stroke. The player drops a ball where the previous stroke was made and replays from there.
Back-on-the-line relief. One penalty stroke. The drop happens on the line from the hole through the spot where the ball last crossed the edge, with no limit on distance behind.
Lateral relief, available only for red penalty areas. One penalty stroke. A ball is dropped within two club-lengths of where the original ball last crossed the edge, no nearer the hole.

All drops are taken from knee height under the post-2019 rules.

What is and is not allowed in a penalty area

Since the 2019 rewrite, the special restrictions that used to apply inside a water hazard are gone. A player in a penalty area can ground the club behind the ball, take a practice swing that touches the ground, and move or remove loose impediments such as stones and twigs.

A few restrictions remain, however. Rule 17.3 confirms that a player cannot take free relief from abnormal course conditions like sprinkler heads or cart paths, cannot declare the ball unplayable inside the penalty area, and cannot take relief for an embedded ball.

A provisional ball is also not available if the player believes the original ball is only likely to be lost inside a penalty area. Stroke-and-distance relief under Rule 17 is the route in that case.

Penalty area vs. other course features

Two other parts of the course often get confused with a penalty area:

Bunker: A bunker is a sand-filled depression governed by Rule 12. It is not a penalty area, and a ball played from a bunker carries no automatic penalty. The two were once grouped together under the older “hazard” umbrella, but the 2019 rewrite separated them.
Out of bounds: Out of bounds lies outside the boundary of the course entirely. A ball that goes out of bounds incurs a one-stroke penalty under Rule 18 and must be played stroke-and-distance from the previous spot. Lateral and back-on-the-line relief are not available.

“Water hazard” is the older name for what the Rules now call a penalty area. The terms cover roughly the same concept, but “penalty area” is broader.

Frequently Asked Questions

Is a penalty area the same as a water hazard?

Effectively, yes. The Rules of Golf retired “water hazard” in 2019 and replaced it with “penalty area.” The new term is broader because it covers non-water areas the Committee chooses to mark.

Do all penalty areas contain water?

No. Most do, but the Committee can mark any difficult area as a penalty area, including thick rough, desert, or jungle.

What is the penalty for hitting into a penalty area?

One stroke, only if the player chooses to take relief. Playing the ball from inside the penalty area is allowed with no penalty.

Can a player take an unplayable ball drop in a penalty area?

No. Rule 17.3 specifies that the unplayable ball option (Rule 19) does not apply inside a penalty area.

Why are some penalty areas red and others yellow?

Color sets the relief options. Yellow is used where carrying the ball over the area is part of the hole. Red, used along the sides of holes, adds an extra lateral relief option to the two yellow options.

What happens if a ball cannot be found in a penalty area?

If it is known or virtually certain that the ball came to rest there, the player may take relief under Rule 17. If not, the ball is treated as lost, and stroke-and-distance relief under Rule 18 applies.
