Obstruction
In short
An obstruction in golf is any artificial object on the course, except boundary objects and integral objects. There are movable obstructions such as rakes and immovable ones such as paved paths. You may remove a movable obstruction without penalty, and for an immovable obstruction there is free relief under certain conditions.
What is an obstruction in golf?
The Rules of Golf define an obstruction as any artificial object. There are two exceptions: boundary objects and integral objects. Everything else that is man-made and lies or stands on the course is an obstruction.
Typical examples are rakes in bunkers, drinks cans, water bottles, benches, bins, paved paths, sprinkler heads, buildings and signs. Natural things such as stones, branches or leaves are not obstructions. They are loose impediments and have their own rules.
Why it matters: an obstruction is a foreign object on the course and should not unfairly affect your game. The Rules therefore let you remove it or take relief if it interferes with your stroke.
Movable and immovable obstructions
The Rules distinguish two kinds. A movable obstruction can be moved without unreasonable effort and without damaging the obstruction or the course. A rake in a bunker, a bucket or a drinks can are examples. Anything that does not meet that test is an immovable obstruction. That includes sprinkler heads, fixed benches, buildings and the artificial surface and sides of paths, for example a paved cart path.
With a movable obstruction the solution is simple: remove it. With an immovable obstruction that is not possible, so you get relief under certain conditions. This is the key difference and the reason the Rules separate the terms so precisely.
If in doubt, ask yourself whether moving the object would take a great deal of effort or cause damage. If so, it is immovable.
Movable obstruction: Rule 15.2
Under Rule 15.2 you may remove a movable obstruction anywhere on the course without penalty, by hand or with a club. If your ball moves as a result, there is no penalty. You replace the ball on its original spot.
If your ball lies in or on a movable obstruction, for example in a drinks can, you lift the ball, remove the obstruction and drop the ball. The reference point is the spot directly below where the ball lay. The ball must come to rest within one club-length of that point, in the same area of the course and not nearer the hole. On the putting green you place the ball on the spot instead.
An exception: you may not move the tee-markers when you are about to play from the teeing area. There are also exceptions if you remove an obstruction deliberately in order to affect a ball in motion.
Immovable obstruction: Rule 16.1 and free relief
For an immovable obstruction, Rule 16.1 gives free relief if there is interference. There is interference if at least one of these applies:
- Your ball touches the obstruction or lies in or on it.
- It interferes with your area of intended stance.
- It interferes with your area of intended swing.
- On the putting green only: it lies on your line of play.
In the general area, a view of the hole being blocked is not enough. The object has to affect your ball, stance or swing.
Here is how you proceed: find the nearest point of complete relief. That is the point nearest to where your ball lies, not nearer the hole, where the obstruction no longer interferes. Then drop a ball within one club-length of that point. One club-length is the length of the longest club in your bag, other than your putter.
Where relief is not available and special cases
Relief is not available everywhere. A ball in a penalty area follows its own rules. There is no free relief from an immovable obstruction there. You play the ball as it lies or take penalty relief under Rule 17.
Further limits:
- No relief applies if playing the stroke is clearly unreasonable for another reason, for example because of where the ball lies.
- No relief applies if you are only affected because of an unreasonable choice of club, stance, swing or direction.
- In a bunker you take free relief within the bunker or, for one penalty stroke, outside the bunker on the line back from the hole.
- On the putting green you place the ball at the nearest point of complete relief, which may be off the green.
If your ball has disappeared into an obstruction and that is known or virtually certain, you may take relief without stroke and distance.
Practical example and common mistakes
Picture a par-4 hole of 340 metres. After a 210-metre drive your ball lies in the grass half a metre from a paved cart path. Your right foot would have to stand on the path to play the stroke. That is an immovable obstruction interfering with your stance.
You find the nearest point of complete relief. That is a point on the grass side where both feet and the swing are clear of the path and which is not nearer the hole. From that point you measure one club-length with your longest club, for example the driver, and drop within that area. The ball must come to rest in the general area and not nearer the hole.
Common mistakes are placing the ball next to the path instead of dropping it, choosing a point of relief that is too far away, measuring with the putter instead of the longest club, or expecting relief in a penalty area. A tip: mark the point of relief with a tee first so that you measure cleanly. If unsure, play two balls in stroke play and settle the ruling later.
Not every artificial object is an obstruction. A boundary object defines the edge of the course, such as a fence or wall at the out of bounds line. You get no relief from it. An integral object is a part of the course the Committee has defined as such, for example a bridge or wall treated as part of the playing area. There is no relief there either.
The immovable obstruction is also only one of four abnormal course conditions. The others are animal holes, ground under repair and temporary water. Rule 16.1 applies to all of them with the same kind of relief.
Which objects count as obstructions can also be set by a Local Rule. For example, the Committee may declare temporary items such as spectator tents or scoreboards to be temporary immovable obstructions for a competition. Always read the Local Rules before your round.

Frequently asked questions
What is an obstruction in golf?
An obstruction is any artificial object on the course, except boundary objects and integral objects. Examples are rakes, benches, sprinkler heads and paved paths. The Rules distinguish movable and immovable obstructions. You may remove movable ones, and for immovable ones there is relief without penalty under certain conditions.
What is an immovable obstruction?
An immovable obstruction cannot be moved without unreasonable effort or without damage. Examples are sprinkler heads, buildings, fixed benches and the artificial surface of paths. If it interferes with your ball, stance or swing, Rule 16.1 gives free relief within one club-length of the nearest point of complete relief.
What is a movable obstruction?
A movable obstruction is an artificial object you can move without unreasonable effort and without damage, such as a rake, a bottle or a bucket. Under Rule 15.2 you may remove it without penalty. If your ball moves as a result, you replace it without penalty.
Is there relief from an obstruction in a penalty area?
No. Rule 16.1 does not apply to a ball in a penalty area. You play the ball as it lies or take penalty relief for one stroke under Rule 17. You may, however, remove a movable obstruction there without penalty.
How far may I drop when taking relief from an obstruction?
You drop within one club-length of the nearest point of complete relief, not nearer the hole and in the same area of the course. One club-length is the length of the longest club in your bag, excluding the putter. The ball must come to rest within the relief area.
