Hazard

A hazard in golf is the traditional name for course features designed to penalise wayward shots, mainly bunkers and bodies of water. The official Rules of Golf retired the term on 1 January 2019 and replaced it with two separate categories: bunkers and penalty areas.

What is a hazard in golf?

For most of the sport’s history, “hazard” was the umbrella word for any course feature placed to challenge the golfer. It covered sand-filled bunkers as well as water on the course in any form: ponds, lakes, streams, even drainage ditches. A ball that landed in any of these areas triggered a specific set of rules that limited what the player could do, and most of the time it cost a stroke to escape.

The Rules of Golf no longer use the word in any official capacity. The 2019 rewrite split the old umbrella into two distinct categories with their own rules, partly because the umbrella was causing confusion and partly because course design had outgrown it. Despite that, golfers, broadcasters, and even instructors still say “hazard” in everyday conversation, and most likely will for a long time.

Hazards exist for one reason: they make a hole more interesting. A flat, open fairway with no danger is a putting contest with extra steps. Bunkers force course management decisions. Water punishes a tee shot that drifts left when the player wanted it straight. The strategic tension between safe and aggressive lines depends on these features being there.

Types of hazards in golf

Hazards came in two main types under the pre-2019 rules. Both still exist on the course today, but each has its own modern name and its own dedicated rule.

Bunkers

A bunker is a hollow filled with sand, intentionally placed to test a player’s accuracy and recovery skills. Course architects use three main kinds: fairway bunkers, found along par 4 and par 5 fairways; greenside bunkers, positioned near and around the green; and waste bunkers, the natural sandy areas often seen on links courses. Waste bunkers are not technically considered hazards under the rules of golf, so unlike fairway or greenside bunkers, players can ground a club lightly in them and remove loose impediments from the area around the ball.

Water hazards

Water hazards covered any body of water marked by stakes or lines, and they split into two sub-types based on stake colour. Yellow ones typically crossed the fairway, forcing the player to hit over them. Red, also called lateral water hazards, ran alongside the fairway, where dropping behind on a straight line was often impractical.

The colour controlled which relief options were available, and that distinction has carried over into today’s penalty area system.

How the 2019 rule change reshaped hazards

The umbrella term of “hazard,” which used to include both bunkers and water hazards, was removed from the Rules of Golf on 1 January 2019. Bunkers and penalty areas are now treated as completely separate categories under the rulebook, according to the USGA.

The water hazard category became “penalty area,” which is a broader concept. Penalty areas can be marked as either red (similar to the old lateral water hazard) or yellow (similar to the old regular water hazard).

The shift was practical. Many clubs had been marking dry areas as water hazards for years, regardless of whether they ever held any water, so the term itself had become misleading. A penalty area can now include desert, lava rock, jungle, and other rough terrain that a course committee chooses to mark, not just water.

The 2019 update also relaxed an old restriction. Under Rule 17, a player whose ball lies in a penalty area can now touch or move loose impediments and ground the club behind the ball, subject only to the rule against improving conditions for the stroke. Bunkers kept the stricter rules: a player still cannot ground the club in the sand before the swing.

Bunkers and penalty areas at a glance

Feature	Bunker	Penalty area (red)	Penalty area (yellow)
What it is	Hollow filled with sand	Often water; can also be desert, jungle, etc.	Typically water that crosses the line of play
Marking	Defined by edges of the sand	Red stakes or lines	Yellow stakes or lines
Penalty for entering	None if played as it lies	None if played as it lies; one stroke for relief	None if played as it lies; one stroke for relief
Grounding the club	Not allowed before the stroke	Allowed	Allowed
Relief options	Limited (one stroke inside, two strokes outside)	Three options, including lateral relief	Two options (stroke and distance, back on line)

What’s not a hazard

A few areas often get lumped in with hazards, but actually are not. The rough, while penal, is part of the general area, not a hazard. Out-of-bounds is its own category and carries the harshest penalty in the rules: stroke and distance with no other relief. Cart paths and sprinkler heads are obstructions, with their own free-relief rules. Casual water, now called temporary water, is a puddle from rain or sprinkler runoff, and a player gets free relief from it under abnormal course conditions.

A waste area, sometimes seen on Floridian and links-style courses, looks like a giant bunker but plays as part of the general area. The player can ground the club, take practice swings, and clear loose objects, none of which is allowed in a true bunker.

Frequently Asked Questions

Is a bunker still a hazard?

Casually, yes. Most golfers still call a bunker a hazard. Officially, no. The Rules of Golf treat bunkers as their own category under Rule 12, separate from penalty areas.

What is the penalty for hitting into a hazard?

For a penalty area, taking relief costs one stroke. A ball played from inside a bunker carries no automatic penalty unless the player chooses to drop outside the bunker for relief, which costs two strokes.

What is the difference between red and yellow stakes?

Both mark penalty areas. Red stakes give the player an extra relief option: a lateral drop within two club-lengths of where the ball last crossed the edge. Yellow stakes only allow stroke-and-distance or back-on-line relief.

Is out-of-bounds a hazard?

No. Out-of-bounds is a separate category with stricter consequences. A ball that comes to rest out-of-bounds must be played again from where the previous shot was taken, with one penalty stroke added.

Why was the term hazard removed from the rules?

The 2019 rewrite was a modernisation effort. The umbrella term created confusion because bunkers and water hazards had different rules, and bundling them together made the rulebook harder to learn. Splitting them clarified the distinctions.
