Ball Lands on a Maintenance Vehicle or Cart: Golf Rules

Ball on a mower, utility cart or maintenance truck? It's free relief: drop within one club-length of the spot under it. Moving vehicle? You must take relief.

If your ball comes to rest on a mower, utility cart or maintenance truck, you get free relief. Lift the ball (or let the vehicle move), estimate the spot right under where it sat, and drop within one club-length of it, no nearer the hole and in the same area of the course. On the putting green you place it instead.

This comes up more often than you'd think. Crews mow fairways during morning tee times, utility carts park beside greens, and a bladed tee shot can find the bed of a truck. A lot of the advice online cites the wrong rule numbers, so this guide sticks to the current text from the Rules of Golf, Rule 15 and Rule 11.

Is a maintenance vehicle a movable or immovable obstruction?

An obstruction is any artificial object on the course other than integral objects and boundary objects. Vehicles, mowers and carts all qualify. The question that decides which rule you use is whether it can be moved.

The Rules treat an obstruction as movable when it can be moved with reasonable effort and without damaging it or the course. A utility cart with an operator sitting in it is movable: the operator can drive it a few yards. A mower parked with the crew member standing next to it is movable for the same reason.

A large machine that is locked, with nobody around and no reasonable way to shift it, is an immovable obstruction. You use Rule 16.1 for that one, which is covered further down. The Committee can also declare a specific object immovable, so check the local rules on the scorecard or notice board if your course posts them.

Golf carts parked beside a green

The same logic applies to carts. A parked cart that can be driven or pushed away is a movable obstruction, and you can have it moved before you play if it is in your way. If your ball is sitting in the basket or on the seat, you take the Rule 15.2 relief below.

What to do if your ball is on a parked maintenance vehicle

This is the most common case: the ball is resting on the seat, in a hopper, or in the bed of a stationary cart or mower.

1. Don't play it from there. The Rules let you play it as it lies, but swinging at a ball on a mower seat risks damage to the machine and to you.
2. Lift the ball. There is no penalty, and you may clean it.
3. Have the vehicle moved. Ask the operator to drive it clear, or move a hand cart yourself.
4. Find the reference point. This is the estimated spot right under where the ball was resting on the vehicle.
5. Measure the relief area. One club-length from that point, using the longest club in your bag other than the putter. It must be in the same area of the course and no nearer the hole.
6. Drop from knee height. The ball must land in the relief area and come to rest in it.

The relief area staying in the same area of the course matters. If the cart is parked on a cart path running through the rough, the spot under the ball is in the general area, so you drop in the general area. If a mower is sitting in a greenside bunker (rare, but crews do rake bunkers with machines), your drop goes in the bunker.

A worked example

Your approach on a 380-yard par 4 comes up short and right, and the ball settles in the basket of a utility cart parked 25 yards from the green. You estimate the spot on the grass right under the basket. You lay your driver down to mark one club-length from that spot, away from the hole, and drop from knee height inside that arc. The ball rolls 2 feet and stops inside it. You play your pitch with no penalty and no loss of distance.

What if the vehicle is moving when your ball lands on it?

Rule 11.1b covers this, and the answer is different. If a ball comes to rest on any moving outside influence, a driven mower or a utility cart in motion included, you must not play it as it lies. You have to take relief.

The reference point is the estimated spot right under where the ball first came to rest on the vehicle, not where the vehicle stopped. If your ball drops into a cart bed at the 150 marker and the driver keeps going 80 yards toward the green, you drop back near the 150 marker. Same one club-length relief area, same area of the course, no nearer the hole. On the putting green you place the ball on the estimated spot instead of dropping.

If your ball merely bounces off a moving vehicle and ends up on the grass, there is no relief. Rule 11.1a says there is no penalty when a ball in motion accidentally hits an outside influence, and you play it from where it stops. That can be good or bad luck.

What if the vehicle drives off with your ball?

Two situations get mixed up here.

• The ball landed on a moving vehicle. Use the Rule 11.1b reference point above: the spot under where the ball first came to rest on it.
• The ball was resting on a parked vehicle and then it drove away. Rule 9.6 applies: your ball was moved by an outside influence, so there is no penalty and it goes back to its original spot. Because the spot was on the vehicle, you take the Rule 15.2 relief from the point right under where the ball sat.

Either way you don't need the original ball back. Rule 9.6 applies whether or not the ball is found, so if it's known or virtually certain the vehicle carried it off (you or a playing partner saw it happen), put another ball into play. If nobody saw it and the ball is simply missing, it isn't virtually certain, and a lost ball means stroke and distance under Rule 18.2. This is a good reason to watch your shot all the way down and to point it out to your group, as we cover in our guide to golf etiquette that still matters.

What if the vehicle can't be moved?

A locked or broken-down machine with no operator around is an immovable obstruction, and Rule 16.1 gives you relief when your ball is in or on it, or when it physically interferes with your stance or swing.

The reference point changes. Instead of the spot under the ball, you find the nearest point of complete relief: the closest spot, no nearer the hole, where the vehicle no longer touches your ball, stance or swing. In the general area you drop within one club-length of that point, and the ball must have complete relief from the vehicle where you drop.

One exception catches people out. Rule 16.1 relief is not available in a penalty area. If a mower breaks down in the red-staked area beside a pond and your ball comes to rest against it, your only options are playing it as it lies or penalty relief under Rule 17.

Quick reference: which rule applies

Is there a penalty for getting it wrong?

The relief itself is free. Mistakes in the procedure are where strokes come from. Dropping in the wrong place and playing the ball is playing from a wrong place under Rule 14.7: the general penalty, two strokes in stroke play or loss of the hole in match play.

The other common error is playing a ball that came to rest on a moving vehicle without taking relief. If you somehow hit it from the cart bed, you have played from a wrong place.

Get the drop right too. If the ball comes to rest outside the relief area, drop again. If the second drop also rolls out, place the ball on the spot where it first touched the ground on that second drop. Don't drop a third time.

A two-stroke penalty on a hole you were managing well is exactly the kind of avoidable damage we cover in how to avoid big numbers and save your round. Thirty seconds of getting the procedure right is cheaper than a triple.

How to handle it on the course without holding up play

Most of the time this takes under a minute. Tell your group what happened before you touch the ball. Wave to the operator and ask them to move a few yards. Mark the reference point with a tee, measure your club-length, drop, and play.

Maintenance crews are used to golfers. They generally prefer you ask them to move rather than climb onto their machine. If the crew member isn't around and the vehicle is a hand-pushed cart or a light trailer, moving it yourself is fine as long as you don't damage it or the course.

Odd rulings like this one are easier when you've seen them before. If you want more of them, our explainers on leaning on a tree while you hit and side-saddle putting walk through two more. And if you log your rounds in Flighting, writing a one-line note on any ruling you took makes it easy to check later whether you handled it correctly.

Frequently Asked Questions

Do I get free relief if my ball lands on a golf maintenance vehicle?

Yes. A vehicle is an obstruction, so a ball resting on one that can be moved gets free relief under Rule 15.2. You drop within one club-length of the spot right under where the ball sat, no nearer the hole.

Can I play my ball off a mower or cart?

If the vehicle is parked, the Rules allow it, but it's rarely sensible and risks damage to the machine. If the vehicle is moving, you are not allowed to play it from there and must take relief under Rule 11.1b.

What happens if the maintenance cart drives away with my ball?

There is no penalty. If it's known or virtually certain the vehicle took your ball, you can use another ball and take relief from the spot under where your ball first rested on the vehicle.

Is a golf cart a movable obstruction?

A cart that can be driven or pushed away with reasonable effort and without damage is a movable obstruction. A cart that can't be moved, such as a locked one with nobody around, is treated as an immovable obstruction under Rule 16.1.

What if my ball hits a maintenance vehicle and bounces into the rough?

There's no penalty and no relief. Under Rule 11.1a you play the ball as it lies from wherever it ends up.
