OB (Out of Bounds) & Hazard Rules Explained: Golf Penalties and Relief Options

Understanding Out of Bounds (OB) and Penalty Areas in Golf

When playing golf, one of the most important rules to understand is how to deal with Out of Bounds (OB) and Penalty Areas. These two zones are marked clearly on the course and can significantly impact your score.

Let’s break it down in a simple and clear way.

Red Stakes and Red Lines: Penalty Areas (Hazards)

You may have seen red stakes or red lines on the course. These indicate a Penalty Area — often referred to as a hazard. If your ball comes to rest in a penalty area, you're allowed to take relief with a one-stroke penalty.

According to the Rules of Golf, a penalty area includes:

• Seas, lakes, ponds, rivers, ditches, surface drainage ditches, or any open water channels — even if they’re dry.
• Any area the committee defines as a penalty area.

White Stakes and White Lines: Out of Bounds (OB)

White stakes or white lines indicate the Out of Bounds (OB) area. OB refers to any area outside the course boundary as defined by the local committee.

Once your ball goes OB, it is considered unplayable, and you must return to the original spot of your last shot to play again with a one-stroke penalty.

The Four Main Areas on a Golf Course

A golf course is divided into four main areas:

1. Teeing Area
2. Penalty Area
3. Bunker
4. Putting Green

Any area beyond these is considered Out of Bounds.

How OB and Penalty Area Affect Your Score

 

The basic rule is simple:
➡️ Both OB and Penalty Area result in a one-stroke penalty. However, the difference lies in how you proceed:

• OB: You must go back to where you played your last shot.
• Penalty Area: You take relief near the area where the ball entered the hazard, under the rules.

 

Example:

If your tee shot goes OB:

• Go back to the tee box
• Hit again as your third shot

If your tee shot enters a penalty area:

• Drop near the entry point (under penalty rules)
• Hit again as your third shot

What If There’s a Drop Zone (Local Rule)?

 

Some courses have designated drop zones (often called OB Tee or Hazard Tee) to speed up play. The rule of thumb:

• OB Tee: Treated as if you’re hitting your fourth shot, assuming your third shot was from the tee.
• Hazard Tee: Treated as if you’re hitting your third shot, just adding the one-stroke penalty.

A Common Real-Life Example (and Confusion)

 

Scenario:

You hit a tee shot, and it might be OB, but you're not sure. There’s a local OB drop zone rule, but your caddie suggests hitting a provisional ball just in case.

 

Your provisional also goes clearly OB.

 

You go to check the first ball and can't find it — it’s confirmed OB. You now head to the OB Tee and play your next shot.

 

👉 Which shot number is this?

 

✅ Answer: It’s your 6th shot.

 

Here’s why:

1. First tee shot (original ball) = 1
2. Provisional ball = 3rd shot (assuming first was OB)
3. That ball also went OB
4. OB Tee: add 2 penalty strokes → Now playing 6th shot

If someone says you're hitting the 4th shot from OB tee, that would only be true if the provisional ball was just a practice swing or "mulligan" — not an official provisional under the rules.

How to Determine OB from Stakes or Lines

OB with Stakes:

• Imagine a straight line between the inside edge of the white stakes.
• If your ball is fully outside this line, it's OB.
• If any part of the ball is still inside the line, it’s in play.

OB with White Line:

• The ball must be entirely inside the white line.
• If it’s touching or outside the line, it’s Out of Bounds.

Final Tip

 

When in doubt, follow local rules and use provisional balls wisely. And always check with your playing partners or committee for clarity.

 

Understanding how OB and penalty areas work can save you both strokes and frustration on the course.

Play smart and... NICE SHOT!
