What Do Red Posts Mean in Golf?

Seeing red posts on a golf course isn't a signal to panic, but a guide for what to do next. Those small stakes or painted lines mark a lateral penalty area, a specific type of hazard with its own set of rules and options. Understanding precisely what they mean and how to proceed is one of the quickest ways to save strokes and play with more confidence. This guide will walk you through exactly what your choices are, how to make the right decision, and how to get back into play without the confusion.

Red Stakes vs. Yellow Stakes: A Quick Primer on Penalty Areas

First, it's helpful to know that not all penalty areas are the same. You'll see two colors on the course: yellow and red. Both allow you to play the ball as it lies (more on that in a moment) or take penalty relief for one stroke. The color simply tells you what your relief options are.

• Yellow Penalty Areas: Marked with yellow stakes or lines, these are typically water hazards that cross in front of a tee box or green, like a creek or pond.
• Red Penalty Areas: Marked with red stakes or lines, these are "lateral" penalty areas. Think of water, woods, or environmentally sensitive areas that run alongside the hole. The rules committee designates them as red because taking back-on-the-line relief (an option for yellow) might be impossible or send you into an unplayable part of the course. Because of this, red penalty areas give you an extra relief option that yellow ones do not.

In short, when you see red, you have more choices. Let's break those choices down.

Option 1: Play It As It Lies (The No-Penalty Gamble)

The first question you should always ask when your ball enters a red penalty area is: "Can I find it, and can I hit it?" If the answer is yes, you are allowed to play the ball from inside the penalty area without taking a penalty stroke. Many golfers automatically assume they have to take a drop, but some of the most heroic and A-plus recovery shots come from within the red stakes.

The Rules Inside the Red Lines

However, if you choose to play from inside the penalty area, the rules are different than a normal shot from the fairway or rough. As of 2019, the rules have become much more lenient, but there are still a few things you must remember:

• You CAN remove loose impediments. Pine cones, leaves, twigs, stones... you are now allowed to move these from around your ball, just as you would anywhere else on the course.
• You CAN ground your club. This is another major change. You are allowed to rest your club on the ground behind the ball at address.
• You CAN take a practice swing that touches the ground. Feel free to make a practice swing inside the penalty area, even if it touches the dirt, water, or grass.

So what's the catch? The catch is usually the lie itself. Playing a ball sitting in a muddy creek bed, entangled in reeds, or nestled at the base of a tree comes with its own set of challenges. Hitting it from there is a calculated risk.

When Is It Worth Playing?

• If you have a clean lie: If your ball is sitting up nicely on pine straw or dry ground just inside the stakes, it's often a great choice to play it.
• Wf you have a clear path forward: A good lie doesn't mean much if a tree is directly in your swing path. Assess if you can realistically advance the ball toward the hole.
• If a penalty drop is a bad alternative: Sometimes, your dropping options might leave you with an awkward yardage or a terrible angle. In those cases, hitting it from the hazard might be the lesser of two evils.

Option 2: Take Penalty Relief for One Stroke

More often than not, your ball will be lost or in an unplayable spot within the red penalty area. When this happens, your best move is to take penalty relief. This will cost you one stroke, but it gets you out of jail and back onto playable ground. Where you drop is based on identifying a specific landmark: the last point of entry.

This is the most misunderstood part of this rule. You must determine the estimated spot where your ball last crossed the red line, not where it came to rest inside the penalty area. Your ball could fly over the line for 50 yards and then roll back toward you for 20. Your point of entry is that spot 50 yards ahead, the last piece of "playable" ground before it crossed the boundary. Once you identify that spot, you have three relief options, each costing one stroke.

Relief Option A: Stroke and Distance

This is your "go back and do it again" option. You can always go back to the spot of your previous shot and play from there, adding one penalty stroke to your score. If you hit your drive into a red penalty area, you can re-tee for your third shot.

• When to Use It: This is sometimes a last resort, but it's a good choice if you can't find your ball or if your other relief options would put you in an even worse position (like a difficult sidehill lie or behind a cluster of trees).

Relief Option B: Back-On-the-Line Relief

This option gives you flexibility on distance. Here's how it works:

1. Identify that all-important last point of entry where your ball crossed the red line.
2. Imagine a straight line extending backward from the hole, through that point of entry.
3. You can drop your a ball anywhere on that line, as far back as you wish. Your drop must be within one a club-length of where the ball first touches the ground on that line.

• When to Use It: This is a fantastic option if taking a drop near the hazard leaves you with a really awkward yardage (like 40 yards) or a bad stance. By going further back on the line, you might get to a flat spot and have a full, comfortable swing with a wedge.

Relief Option C: Lateral Relief (The Red Stake Specialty)

This is the bonus option that only exists for red penalty areas. It's often the most popular choice because it lets you stay closest to where your ball went out of play.

1. Identify the last point of entry.
2. From that point, you can measure two club-lengths (using the longest club in your bag that isn't a putter).
3. You can drop your ball anywhere within that two-club-length arc, as long as it is no nearer to the hole.

• When to Use It: This is the go-to option when you hit one sideways into woods or water running alongside the fairway. It allows you to drop in the rough or fairway adjacent to the penalty area and continue playing down the hole without losing much distance.

A Real-World Golf Scenario: Making the Smart Choice

Imagine you're on a long par 5. There's a creek marked by red stakes running all the way down the right side of the fairway. Your second shot, a 3-wood, slices hard to the right and you hear it splash in the creek about 220 yards from the green.

Let's walk through your thought process:

1. Find the Point of Entry: You walk forward and identify the spot where your ball last crossed the red line marking the creek bed. Let's say it's 230 yards out. The ball itself is sitting in 2 inches of water, so playing it is not an option.
2. Assess Option A (Stroke and Distance): You hit your 3-wood from about 280 yards out. Going all the way back to hit your fourth shot from there feels like a big step backward. You pass on this one.
3. Assess Option B (Back-on-the-Line): From your point of entry (230 yards out), going straight back from the pin would put you in the right rough, and every step back leaves you further from the green. Not ideal.
4. Assess Option C (Lateral Relief): This is probably your winner. You measure two club-lengths from the point of entry, no nearer the hole. This drops you in the right rough, perhaps on a decent lie, still 230 yards from the green. You'll be hitting your fourth shot, but you have a clear path and a chance to get near the green to save par or secure an easy bogey.

By calmly thinking through your options, you've chosen the one that gives you the best statistical chance of scoring well, all thanks to knowing precisely what those red posts mean.

Final Thoughts

Red posts are not a sentence for a poor score, but rather a set of choices for you to make. To summarize, you can either play the ball as it lies without penalty or, for a one-stroke penalty, take relief using one of three options: replaying from the previous spot, using back-on-the-line relief, or using the special two-club-length lateral relief option unique to red areas.
