Loose impediment
In short
A loose impediment in golf is a loose natural object on the course, such as a stone, a leaf or a broken twig. It is not attached or growing, not solidly embedded and not sticking to the ball. Since 2019 you may remove loose impediments anywhere on the course without penalty, including in bunkers and penalty areas.
What is a loose impediment?
The Rules of Golf define a loose impediment as any natural object that is not fixed. Golfers usually just say ‘loose impediment’.
This includes:
- stones, pebbles and pine cones
- leaves and loose grass or turf clippings
- broken twigs and branches
- dead animals, worms, insects and their casts or heaps, for example an anthill
- spider webs, even though they are attached to something
What matters is that the object is natural and loose. The Rules call them impediments because such objects can interfere with your stroke if they lie right next to the ball or in your swing. Removing them takes away that interference. Since 2019 it makes little difference where on the course they lie.
What is not a loose impediment?
Not every natural object counts. The Rules name several exceptions:
- Anything attached or growing, such as grass, bushes, trees and roots that are connected to the ground.
- Objects solidly embedded in the ground, that is, not easily picked out. A large, half-buried stone is one example.
- Objects sticking to the ball, such as mud.
- Sand and loose soil. They are natural but not loose impediments. On the putting green you may still remove them.
- Dew, frost and water.
Snow and natural ice, other than frost, have a special status. You may treat them either as a loose impediment or as temporary water, whichever suits you better. This choice applies only to snow and ice.
Removing without penalty: Rule 15.1
Under Rule 15.1 you may remove loose impediments anywhere on the course, using any method: by hand, with a club, with your foot or with a towel. This applies in the general area, on the putting green, in the teeing area and also in bunkers and penalty areas. Until 2018 that was forbidden in bunkers and water hazards, where touching a stone next to your ball cost a penalty.
You may remove the object at any time, whether or not it interferes with your swing, stance or line of putt. All that matters is that the ball stays at rest.
There are two exceptions. You may not remove an object deliberately to affect a ball that is already moving. A second exception concerns a ball lifted anywhere except on the putting green that must be replaced: before replacing it, you may not deliberately remove an object that would probably have moved the ball if you had removed it while the ball was there.
When the ball moves while you remove an object
The delicate moment comes when you remove a loose impediment right next to the ball and the ball wobbles or rolls. Under Rule 15.1b you replace the ball on its original spot. Usually a penalty stroke follows too, because you moved the ball, under Rule 9.4b.
On the putting green it is simpler. If you accidentally move the ball there, there is no penalty. You replace it and play on. There is also an exception during a search: if you accidentally move your ball while searching for it, there is no penalty.
The practical consequence: remove stones, leaves and twigs near the ball slowly and gently. Touch only the object, not the ball. If that is not enough and you are unsure whether the ball might move, leave the object where it is and play the ball as it lies.
Practical example: a ball in autumn leaves
Picture a par-4 hole in autumn. Your ball lies on the fairway after your tee shot. Around it are loose leaves and a broken twig 30 centimetres long. Neither touches the ball. The twig lies exactly where your club would pass in the backswing.
You may remove the twig and the leaves. You pick the twig up by hand and put it aside without touching the ball. Then you play the stroke normally. There is no penalty.
It is different if a leaf sticks to the ball. It is then no longer a loose impediment. You play the ball as it lies unless a Rule allows you to lift it.
Common mistakes and tips
Beginners are often unsure here.
- Smoothing sand in a bunker: sand is not a loose impediment. You may not touch it to test its condition, nor with your club right in front of or behind the ball.
- Breaking off an attached twig: a branch hanging on the tree is attached. Do not break it off to improve your swing.
- Pulling out grass: grass and roots are growing. You may not remove them.
- Ball moved, penalty ignored: if the ball moves during removal, replace it and count the penalty stroke where one applies.
A tip: before the stroke, check quickly which things near the ball are loose. Remove only what is necessary. Then you stay in control and rules questions do not even arise.
Distinctions: loose impediment, obstruction and ground under repair
A loose impediment is always natural. An obstruction is always artificial, such as a rake or a bottle. That is the key difference. With an obstruction it matters whether it is movable or immovable. With a loose impediment the rule is simple: you may remove it.
It also differs from ground under repair. Ground under repair is an area the Committee has defined as such, usually by marking it, for example a freshly worked spot. There you get free relief under Rule 16.1. That is not needed for a loose stone, because you simply remove it.
Grass and leaves differ as well: freshly cut grass lying loose is a loose impediment. Grass still growing in the ground is not.
Try it at Golf Lounge
The 9-hole ‘Black’ course at the Golf Lounge Resort Hamburg has water hazards, bunkers and protected greens. There you can experience rules situations such as loose stones, leaves or twigs in practice. The course is playable with the DGV Platzreife, open from April to December and can be booked for up to four players per tee time. If you would like to learn the rules first, start with the Platzreife course, which combines theory on rules and etiquette with practice.
Frequently asked questions
What is a loose impediment in golf?
A loose impediment is an unattached natural object, for example a stone, a leaf, a twig, a dead worm or an anthill. It is not attached or growing, not solidly embedded and does not stick to the ball. You may remove it without penalty under Rule 15.1.
May I remove a stone next to my ball in a bunker?
Yes. Since 2019 you may remove loose impediments without penalty in bunkers and penalty areas too. The ball must not move. Sand and loose soil are not loose impediments. You may not touch the sand to test it or with your club right in front of or behind the ball. It is usually enough to lift the stone gently without touching the ball itself.
What happens if the ball moves while I remove a loose impediment?
You replace the ball on its original spot. Usually a penalty stroke follows because you moved the ball. On the putting green there is no penalty if the ball is moved accidentally. If you accidentally move your ball while searching for it, there is no penalty either.
Is sand a loose impediment?
No. Sand and loose soil are natural but not loose impediments. On the putting green you may remove both. In a bunker you must not touch the sand before the stroke to test or improve the lie. Smoothing the sand around the ball to improve your lie is not permitted either.
Are snow and ice loose impediments?
Snow and natural ice, other than frost, may be treated, at your choice, either as a loose impediment or as temporary water. As a loose impediment you remove them, as temporary water you take relief under Rule 16.1. Dew, frost and water are not loose impediments.
