Golf Immovable Obstruction Rules: Free Relief on Cart Paths and More

Immovable obstructions — artificial course structures that cannot be moved — entitle you to free relief when they interfere with your stance or swing. Cart paths are the most common example. Knowing exactly when you get relief and how to take it correctly prevents both incorrectly accepting relief and incorrectly refusing it.

What Is an Immovable Obstruction?

Immovable obstructions are artificial objects that cannot be moved without unreasonable effort, or moving them would cause damage to the course. Common examples: cart paths, paved roads, drainage ditches with artificial lining, fixed benches, sprinkler heads, yardage markers embedded in ground, bleachers, maintenance buildings. These objects are not defined as 'part of the course' — you get interference relief.

Key Rule: Natural objects (trees, rocks, bushes) are NOT obstructions — they're part of the course. Only artificial objects qualify.

When Interference Exists

You have interference from an immovable obstruction when: (1) The obstruction physically touches you or your club during your stance or swing. (2) The ball lies on or in the obstruction. Importantly: interference does NOT include cases where the obstruction merely lines up between your ball and the hole, or is beyond the ball in your target direction. Only physical interference with stance or swing counts.

Key Rule: If you can swing normally without the cart path touching you or your club, you don't have interference — even if the path is 1 inch away.

How to Find Your Nearest Point of Complete Relief

Step 1: Take your normal grip and stance as if to play the ball as it lies. Step 2: Find the nearest point — in any direction — where you can take a stance and swing without any interference from the obstruction. Step 3: Drop within one club-length of that point, no nearer the hole. The drop must be in the same 'area of the course' (not from rough to fairway, for example).

Key Rule: 'Nearest' means geographically closest — not the most favorable. You cannot choose relief to the more advantageous side.

Special Cases: Line of Play Interference

On the putting green, you also get relief from immovable obstructions on your line of putt — even if they don't affect your stance. This is different from off the green, where only stance/swing interference qualifies. A sprinkler head on your putting line entitles you to relief on the green; the same sprinkler between your ball and the green off the green does NOT.

Key Rule: The on-green line-of-putt relief for immovable obstructions is a distinct exception from the general rule.

When You Choose NOT to Take Relief

You always have the option to play from the cart path (or any immovable obstruction) if you prefer. Some lies on a cart path offer a better lie than the rough alternative. Players sometimes prefer a cart path lie when the relief option drops them in rough or near another obstacle. Make sure you make a conscious choice and don't inadvertently take an impermissible drop.

Key Rule: Playing from a cart path protects your club from damage — consider keeping a spare wedge for such shots.

Dropping Zones and Local Conditions

Some courses use dropping zones near common obstruction areas. These are marked areas designated for drops — use them when posted instead of the standard procedure. Also: temporary conditions (casual water, ground under repair) sometimes appear alongside immovable obstructions. You may get relief from both simultaneously using the procedures in the applicable order.

Key Rule: When dropping zones are available, they're usually chosen by the committee to provide fair relief — use them if in doubt.

Key Takeaways

→ Cart paths = most common immovable obstruction — free relief when interfering
→ Nearest point of complete relief, no nearer the hole, within one club-length
→ 'Nearest' is geographical, not the most favorable — you can't choose the better side
→ On the putting green, you also get line-of-putt relief
→ You may always choose to play from the obstruction if preferred
