You’re sitting on the couch, wings in hand, and the yellow flag flies. Everyone screams. Then, the referee steps into that clear patch of grass, clicks his mic, and starts performing what looks like a rhythmic interpretive dance. If you aren’t a die-hard stats geek, those signals for football penalties can feel like a secret language designed to confuse you. We've all been there, squinting at the screen trying to figure out if it’s a false start or an illegal shift before the announcer even opens his mouth.
It's chaotic.

The NFL rulebook is currently over 90 pages of dense, legalistic jargon, and the signals are the only visual shorthand we have to make sense of the madness. Honestly, these gestures haven't changed much since the days of leather helmets, but the game around them has become a blur of speed and complexity. If you want to actually understand why the drive just died, you have to look past the flag and watch the hands.
The Most Common Signals for Football Penalties You’ll See Every Sunday
Let’s talk about the False Start. It’s the bread and butter of unforced errors. You see the ref rolling his forearms over each other like he’s practicing a very slow speed-bag routine. It’s simple. It’s iconic. But did you know it’s technically the same signal used for "illegal motion"? The difference is usually in the context of the play and whether the whistle blew before or after the snap.
Then there’s Holding. This is the one that ruins every 40-yard touchdown run. The ref grabs his own wrist in front of his chest. It looks like he’s trying to stop himself from punching someone. In reality, he’s demonstrating exactly what the offensive lineman did to the defensive end’s jersey. According to Football Zebras, a leading independent source on officiating, holding is consistently the most called penalty in the league, largely because it happens on almost every play—it's just a matter of whether the official sees it or decides it's egregious enough to influence the play.
Why Holding Signals Feel Inconsistent
Fans hate it.
The "Holding" signal is often a point of massive contention because of the "inside the frame" rule. If a blocker’s hands are inside the defender's chest, it’s usually clean. The moment those hands move outside to the shoulders and the ref pulls his wrist? That’s ten yards back. It’s a judgment call that happens in a fraction of a second, which is why you see refs like Sarah Thomas or Clete Blakeman making such decisive, sharp movements. They have to sell the call to 70,000 screaming people who probably disagree.
The Weird Ones: Personal Fouls and Unsportsmanlike Conduct
When a player loses his cool, the signals get more dramatic. For a Personal Foul, the referee brings his arm down in a chopping motion against his other wrist. It’s a literal "cut it out" gesture. But if things get really spicy and someone gets an Unsportsmanlike Conduct penalty, the ref spreads his arms out wide, palms down, like he’s trying to fly or maybe just telling everyone to calm the heck down.
Actually, the "Personal Foul" signal is the umbrella for some of the most dangerous hits in the game.
- Facemask: A pulling motion in front of the face.
- Horse-collar: A hand tugging at the back of the neck area.
- Roughing the Passer: A personal foul signal followed by a simulated "passing" motion.
These signals for football penalties carry a 15-yard weight. They change games. When you see the official give that chopping motion, the energy in the stadium shifts instantly because everyone knows a "chunk" of yardage is about to be handed over. It’s the ultimate momentum killer.
The Mystery of the "Ineligible Man Downfield"
This one is a headache for casual viewers. The ref puts his hand on top of his head. It looks like he’s checking to see if his hat is still there. In reality, he’s flagging a big guy—an offensive lineman—for wandering too far past the line of scrimmage on a pass play. Under NFL Rule 8, Section 3, Article 1, linemen can't be more than one yard downfield when a pass is thrown. It’s a tiny margin of error. One yard! If a guard gets excited and starts hunting for a linebacker too early, out comes the flag and the hand goes to the head.
Why Do Referees Use These Specific Gestures?
History. That’s basically the answer.

In the early 1900s, there were no microphones. Referees had to communicate with the press box and the fans using nothing but their bodies. The "Offside" signal—hands on hips—is meant to be visible from the furthest seat in the nosebleeds. It’s a "look at this guy" stance. Most of these gestures were standardized by the 1940s and haven't really evolved because they work. They are high-contrast movements that are hard to mistake, even in a snowstorm or under flickering stadium lights.
The Signal for "Declined" or "Offsetting" Fouls
Sometimes the flag flies and... nothing happens. This is where you see the "incomplete pass" signal—the arms crossing and uncrossing in front of the body. If both teams commit a foul, the ref does this to show they cancel each other out. It's essentially the "delete" button of football. You’ll also see this if a coach decides to decline a penalty because the result of the play was actually better than the yardage gain from the foul.
Beyond the Basics: The Nuance of Intentional Grounding
Intentional Grounding is perhaps the most complex signal to perform and to call. The referee makes a diagonal "chopping" motion with both hands in front of his body, mimicking the path of a ball being thrown into the dirt. But the signal is only half the story. To make this call, the ref has to coordinate with other officials to confirm:
- Was the quarterback outside the "pocket" (the tackle box)?
- Did the ball reach the line of scrimmage?
- Was there a realistic receiver in the area?
If the answer to these is "no," "no," and "no," the ref does the chop. It’s a devastating penalty because it results in a loss of down AND the yardage is spotted at the point of the foul.
The Evolution of the Signal: Modern Replay Review
We can't talk about signals for football penalties without mentioning the "TV Signal." You know the one—the ref mimics a square or a rectangular screen with his index fingers. This isn't technically a penalty signal, but in the modern era, it's the most important gesture on the field. It means the "eye in the sky" is taking over.
When that square is drawn in the air, the previous signals are essentially on hold. It’s a weird tension. The crowd waits. The players wait. The ref goes to the black hood or looks at a tablet. It’s a reminder that while the physical signals are rooted in the 1920s, the 2026 version of the game is governed by fiber-optic cables and high-definition slow motion.
Real-World Example: The "Fail Mary" and Signal Confusion
One of the most famous (or infamous) moments in officiating history happened during the 2012 "Fail Mary" game between the Packers and the Seahawks. Two different officials made two different signals at the exact same time. One signaled a touchback (arms out), and the other signaled a touchdown (arms up). It was pure chaos. That moment proved why clear, singular signals for football penalties and scoring are so vital to the integrity of the sport. When the signals fail, the game loses its grip on reality.

A ref reaching for his hip usually means a flag is coming. A ref sprinting toward the spot of the ball with his bean bag out means a change of possession. If you see the "Ref Body Language" early, you can predict the call.
- Hands on hips? Someone was offside or neutral zone infraction. Get ready for a 5-yard move.
- Tapping the top of the head? Ineligible man downfield. Probably a screen pass gone wrong.
- The "Windmill" arm motion? The clock is running. Hurry up.
- Hands behind the back? This is "Illegal Use of Hands." Usually a blow to the head or a face-to-face shove that wasn't quite a punch.
Actionable Takeaways for the Fan
Learning the signals for football penalties isn't just about being a nerd; it's about enjoying the game without the frustration of the "wait." Here is how you can level up your viewing experience:
- Watch the "Umpire" and the "Down Judge": These are the officials usually responsible for the line of scrimmage. If their hands go to their hips immediately, it's a pre-snap foul. You don't even need to watch the rest of the play.
- Identify the "White Hat": The Referee (the one with the white hat) is the ultimate authority. Even if another ref throws a flag, the White Hat is the one who will give the final signal. Always track him after the whistle.
- Listen for the "Thud": Often, you can hear a holding or a late hit before you see the signal. If you hear a loud "slap" of pads away from the ball, look for the ref grabbing his wrist.
- Use a Cheat Sheet: Keep a digital image of the official NFL signal chart on your phone. After three games of checking it, you’ll have 90% of them memorized.
The next time a flag hits the turf, don't wait for the commentator to explain it. Look at the official. Watch for the wrist grab, the forearm roll, or the hand to the head. You’ll be calling the penalty before the ref even turns on his microphone, which—let’s be honest—is the best part of being a football fan.
Knowing these gestures turns a confusing jumble of interruptions back into a strategic game of inches. You aren't just watching a game anymore; you're reading it. That's the difference between a casual viewer and someone who actually understands the grind of the gridiron.
Next time you’re watching, pay attention to the referee's "secondary" signals—the ones they use to talk to each other, like the "incomplete" wave used to signal a "dead ball" or the "pointing" to indicate which team gets the yardage. It’s a whole different layer of the sport that most people just ignore.
