Maybe the better question is “What can’t you move?”
You may not move anything in a hazard even if the object is interfering with your shot. In the photo, you’ll notice that even though the ball is clearly within the hazard markings, it is very playable. The only problem is the reed (a loose impediment) lying on top of the ball. Unfortunately, you may not move the reed. You have to play the ball as it lies – without grounding your club. That makes the shot a little more challenging but not impossible. By the way, this rule applies to the bunker as well.
Let’s go back to the original question. What can you move? You may move any movable obstruction (man-made objects), such as a candy wrapper or cigarette butt – even in a hazard. Movable obstructions are defined as anything that “may be moved without unreasonable effort, without unduly delaying play and without causing damage.” (Rule 24) You might want to be proactive in marking your ball before you try to move a movable obstruction. If your ball moves, you must replace it without penalty.
You may only move loose impediments (natural objects) – things such as twigs, rocks, and leaves outside of hazards. One thing to remember is that if, in the act of moving a loose impediment, your ball moves, you must take a penalty stroke and replace your ball.
By the way, I was playing golf today when out of the blue, one of my companions said, “I just love playing golf!” So do I! Enjoy this beautiful season of golf.
