Can Police Handcuff You or Put You in the Patrol Car During a Traffic Stop?

Almost everyone knows an officer can tell you to step out of your car. Far fewer know where that authority stops. Can they frisk you? Handcuff you? Lock you in the back of the patrol car? The line between a lawful stop and an arrest runs right through those three questions.

“Step out of the car” is one of the most familiar commands in American life, and most people obey it without a second thought, because they have heard, correctly, that an officer is allowed to say it. What almost no one knows is how far that authority reaches. Getting you out of the car is the first rung on a ladder, and every rung above it, the frisk, the handcuffs, the patrol car, requires more legal justification than the one below.

The short answer

During a lawful stop, an officer can order you and your passengers out of the car. That much is settled, and it is treated as a minor intrusion. But the authority does not automatically climb from there. To frisk you, the officer needs specific reason to believe you are armed and dangerous. To handcuff you and confine you in a patrol car, the officer generally needs the kind of particularized justification that starts to look like probable cause, because at some point those measures stop being a brief detention and become a full arrest, which the Fourth Amendment does not allow without probable cause. “Officer safety” justifies the small step. It does not automatically justify the big ones.

GREG KIRAKOSIAN’S LEGAL EYE VIEW

“Step out of the car” is where most people stop knowing their rights, so let me pick up where that ends. Getting you out of the car is the small, allowed step. The handcuffs and the back of the patrol car are a different animal, and in my experience officers count on you not being able to tell the difference. Each step up the ladder needs its own reason. When they skip the reasons and go straight to the cuffs, a traffic stop has quietly become an arrest.

The floor: what Pennsylvania v. Mimms actually allows

Start with the case every officer leans on. In Pennsylvania v. Mimms (1977), officers stopped a driver for an expired plate and ordered him out, as routine. When he stepped out, an officer saw a large bulge under his jacket, frisked him, and found a loaded revolver. The Supreme Court upheld the order to get out, because the safety benefit is significant and the added intrusion of standing outside is minor. Mimms, 434 U.S. at 111 (calling the added intrusion “de minimis”). Maryland v. Wilson (1997) extended the same rule to passengers. But notice the part officers gloss over. Mimms did not authorize the frisk automatically. The pat-down was lawful only because the officer saw the bulge, a specific fact suggesting a weapon. Even in the case that gives police their broadest routine authority, the step from “get out” to “hands on you” required something more. That is the whole lesson of the ladder.

Rung two: the frisk requires armed and dangerous

Getting you out of the car is automatic. Patting you down is not. A frisk is a search, allowed only when the officer has reasonable suspicion that you are both armed and dangerous. That rule is from Terry v. Ohio (1968), and the Supreme Court applied it to the traffic-stop setting in Arizona v. Johnson (2009): even during a valid stop, an officer may frisk a driver or passenger only with reason to believe the person is armed and dangerous. 555 U.S. at 327. A hunch will not do, and neither will the mere fact that a stop is happening. In Mimms, remember, it was the visible bulge. No bulge, no frisk.

Rung three: handcuffs start to look like an arrest

Handcuffing is a serious jump, and courts treat it that way. The Ninth Circuit, which governs California, has held that aggressive tactics like drawing guns and applying handcuffs will ordinarily convert a brief investigative stop into a full arrest, requiring probable cause, unless the officer has a particularized, articulable basis to believe such measures are necessary for safety (Washington v. Lambert, 98 F.3d 1181, 1186-89 (9th Cir. 1996)). The court’s own line is worth quoting exactly: “Under ordinary circumstances, when the police have only reasonable suspicion to make an investigatory stop, drawing weapons and using handcuffs and other restraints will violate the Fourth Amendment.” Id. at 1187. Lambert happened in our backyard. Around midnight in Santa Monica, two Black men visiting from New York, professionals, drove into their hotel garage. Officers followed them in, ordered them out at gunpoint, handcuffed them, and put them in separate patrol cars, because they supposedly resembled a vague bulletin, “one fairly tall, one fairly short.” The Ninth Circuit held this was not a brief stop at all. The guns and cuffs had turned it into a full arrest, and with no probable cause, it violated the Fourth Amendment. The point is not that handcuffs are never allowed. It is that they cannot be the default, and “it was late and this looked like a bad area” is exactly the vague justification Lambert rejected. And Lambert is not stale law. In 2024 the Ninth Circuit reversed a summary judgment that had cleared about a dozen LAPD officers who ran a high-risk felony stop on a woman driving home from a family celebration with her teenage daughter and a friend, ordered her out at gunpoint, made her lie face down in the street, and handcuffed all three occupants, all because a DMV error had put the wrong plates on her car. The court held Lambert had already clearly established that officers can be held liable for a high-risk vehicle stop built on nothing more than a suspicion that the car was stolen. Chinaryan v. City of Los Angeles, 113 F.4th 888, 893, 907-08 (9th Cir. 2024).

Rung four: the patrol car is custody, and custody means arrest

Putting a person in the back of a patrol car is the most custodial move short of hauling them to jail. In Dunaway v. New York (1979), police had a lead on a suspect but not enough for a warrant. They “picked him up” anyway, drove him to the station, and put him in an interrogation room. He was never told he was under arrest and never booked, but he was not free to leave. The Court held that this custodial seizure, on less than probable cause, was so much like an arrest that it violated the Fourth Amendment. 442 U.S. at 216. The label did not matter. What mattered was the reality of the custody. And the Court has said a detention must use the least intrusive means reasonably available (Royer, 460 U.S. 491, 500 (1983)). Locking someone in a patrol car is close to the opposite of that.

The ladder, and back to Johnathan

• Order you out of the car: yes, automatically (Mimms; Wilson).
• Frisk you: only with specific reason to believe you are armed and dangerous (Terry; Johnson).
• Handcuff you: only with a particularized safety justification, or it becomes an arrest (Lambert).
• Put you in the patrol car: this is custody, and without probable cause it is a de facto arrest (Dunaway).

Now Johnathan’s stop. The deputy was entitled to order him out of the car; that was the lawful floor. The search of Johnathan’s person happened by consent and turned up nothing. But then the deputy handcuffed him and confined him in the patrol car for about eight minutes. There was no probable cause to arrest, the deputy admitted as much, and his justification was the familiar generalized one: 3 a.m., alone, a high-crime area. Under Lambert and Dunaway, that is the profile of a stop that climbed past what Mimms permits and turned into an arrest with nothing to support it. And on his own body camera, the real reason he gave a fellow officer for cuffing Johnathan was not safety at all. It was that Johnathan “was just running his mouth.”

The officer-safety limit, stated plainly

Officers reach for “officer safety” to justify every rung, so be precise about what it actually buys. It buys the small, standardized step of getting you out of the car, because that is minimal and applies evenhandedly. It does not buy a frisk unless there are specific facts that you are armed and dangerous. And it does not buy handcuffs and the patrol car unless there is a particularized reason, tied to you and the real situation, to believe those extraordinary measures are necessary. Traffic stops can be dangerous, and the law takes that seriously. But “danger in the abstract” is not the same as “this person, right now, is dangerous,” and only the second kind justifies climbing the ladder.

What to do if it happens to you

1. Comply with lawful commands. If you are told to step out, step out. Refusing that order will only hurt you.
2. Do not physically resist a frisk, handcuffs, or being placed in the car, even if you believe it is unlawful. Resisting turns a rights violation into a new charge and can get you hurt.
3. Put your objection on the record with words, not force: “I do not consent to any searches,” and “Am I under arrest?”
4. You do not have to answer unrelated questions. “I would rather not answer questions” is enough.
5. Remember everything, and if it is safe and lawful, record it: what you were told, when you were cuffed, how long you sat in the car, and the reasons the officer gave.
