Lights in the mirror. You pull over, and within a few minutes the officer may ask you to step out, ask where you’re headed, ask to look in the car, or ask to see your phone. Most people say yes to all of it. They assume they have to, or that saying no will make things worse.

The short answer: some things you must do, and many things you can politely decline. You must stop, hand over your license, registration, and proof of insurance, and step out if ordered. You do not have to answer questions about your trip, agree to a search of your car, or let anyone go through your phone. Declining is not a crime. Physically resisting is.

This guide walks through a stop from start to finish: what to do in the first minute, what you’re required to do, what you can refuse, how to say it, and how to protect your phone. Where Ohio law differs from the general rule, it says so.

The first minute

How the stop starts sets the tone for everything after. The goal is to look like what you are: a calm person who isn’t a threat.

  • Signal, pull over to the right as soon as it’s safe, and turn off the engine.
  • At night, turn on the dome light.
  • Roll the window down partway and put your hands on the steering wheel. Passengers keep their hands visible too.
  • Don’t dig for documents until the officer asks. Then say where they are before you reach: “My registration is in the glove box. I’m going to get it now.”
  • Keep your license, registration, and insurance card somewhere easy to reach, and away from anything you’d rather not have in view.
  • You can record the stop on your phone, but mount it or set it on the dash before the officer walks up. Don’t hold it out toward them.

What you must do, and what you can decline

The line falls between following lawful orders and volunteering cooperation. Orders you follow. Requests you can turn down.

Situation Required? What the law says
Show license, registration, insurance (driver) Yes Required of drivers in every state.
Step out of the car when ordered Yes Pennsylvania v. Mimms (1977) lets officers order the driver out of a lawfully stopped car. Maryland v. Wilson (1997) extends that to passengers. Get out calmly; you can still say you don’t consent to a search.
Give name, address, date of birth (passenger) Depends on the state In Ohio, yes, when the officer reasonably suspects a traffic violation (see Ohio notes). Elsewhere, often only if suspected of a crime.
Answer questions (“Where are you headed?” “Been drinking tonight?”) No You can say, “I don’t answer questions,” or simply stay quiet beyond identifying yourself.
Consent to a search of the car No Say, “I don’t consent to any searches.” See the next section.
Pat-down of your outer clothing You can’t stop it An officer who reasonably suspects you’re armed and dangerous can frisk you. Don’t resist; say you don’t consent to any further search.
Wait while a drug dog is brought in Not without suspicion Rodriguez v. United States (2015): police can’t extend a finished traffic stop for a dog sniff without reasonable suspicion of a crime.
Let them look through your phone No Covered in detail below.

If you think an order is unlawful, comply anyway and challenge it later. The roadside is the wrong place to win a legal argument.

Searching your car

Cars get less protection than homes, but you still control the most common way a car gets searched: consent.

  • “Mind if I take a look?” is a request. Answer: “I don’t consent to any searches.” You don’t need to give a reason.
  • Probable cause is the big exception. If an officer has probable cause to believe the car holds evidence of a crime (an odor, something in plain view, a dog alert), they can search without a warrant or your permission.
  • Plain view. Anything visible from outside the car is fair game. Keep the interior clear.
  • Arrest. If someone in the car is arrested, police can search areas tied to that arrest in some situations, and an impounded car will be inventoried.
  • Your phone is separate. Even when police lawfully search the car, they still need a warrant to go through the phone they find in it.

If they search anyway, stand where you’re told, repeat “I don’t consent to this search,” and don’t interfere. Your refusal on the record is what a defense lawyer works with later.

Staying silent, and leaving

Your right to remain silent only works reliably if you say out loud that you’re using it. The Supreme Court has held that simply going quiet isn’t enough to invoke it. Use plain words: “I’m going to remain silent.”

A few things to keep straight:

  • Silence isn’t lying, and lying is worse than silence. Never give a false name or a made-up story. That can be a crime on its own.
  • Small talk is still talk. “Where are you coming from?” is an investigative question. A friendly tone doesn’t change that.
  • You aren’t free to leave until the officer says so. A traffic stop is a detention. Once you’ve got your ticket or warning back, ask: “Am I free to go?” If the answer is yes, leave. If it’s no, ask, “Am I being detained? For what?”
  • If you’re arrested, say, “I’m going to remain silent, and I want a lawyer.” Then stop talking, about anything, until a lawyer is there.

Ohio notes

Two Ohio rules change the general advice above.

Identifying yourself, drivers and passengers. Ohio’s House Bill 492 took effect October 7, 2026. If an officer reasonably suspects a driver or passenger of a motor-vehicle violation, that person must give their name, address, and date of birth when asked. Nothing more is required under that law. Refusing is a fourth-degree misdemeanor. The law also raises the penalty for interfering with an officer enforcing traffic laws to a second-degree misdemeanor, with up to 90 days in jail. Legislators passed it after Ohio appeals courts held that refusing to identify wasn’t obstruction. Expect early court fights over when a passenger can be suspected of a traffic violation.

Carrying a handgun. Since Senate Bill 215 took effect in June 2022, Ohio no longer requires you to volunteer that you’re carrying a concealed handgun. But if an officer asks, you must answer truthfully. You must also keep your hands in plain sight from the time the officer approaches until they leave, unless they tell you otherwise. Many carriers choose to tell the officer up front anyway, before any reaching for documents.

If they ask for your phone: police need a warrant

In Riley v. California (2014), a unanimous U.S. Supreme Court held that police generally must get a warrant before searching the digital contents of a cell phone. That holds even after a lawful arrest. Before Riley, officers could search items on an arrested person, like a wallet or a cigarette pack. The Court said phones are different because they hold a record of nearly every part of a person’s life.

A routine traffic stop for speeding or a broken taillight does not, by itself, give an officer the right to go through your phone.

The key word is generally. There are exceptions, and the biggest one is the one you control: consent.

Asking is not demanding

If you agree to a search, police don’t need a warrant. Consent waives your Fourth Amendment protection, and anything they find can generally be used against you. Consent also doesn’t have to be a formal “yes.” Unlocking the phone and handing it over can count.

So listen to how the request is phrased:

  • “Can I see your phone?” / “Mind if I look?” — This is a request. You can decline.
  • “Give me your phone.” — Still ask: “Do you have a warrant?” An order is not the same as legal authority, and you can state that you don’t consent.
  • “We have a warrant.” — Ask to see it. Don’t interfere, but don’t add consent to it either.

Declining is not an admission of guilt, and it is not a crime. It also keeps the question clean if the search is challenged later: a court looks very differently at a search you agreed to and one you clearly objected to.

Saying no doesn’t make you untouchable. Know the limits so nothing surprises you.

  • They can take the phone and hold it. If officers believe it contains evidence of a crime, they can seize it while they apply for a warrant. Seizing the device is not the same as searching its contents.
  • They can get a warrant. Then they can search it, often with forensic tools that don’t need your help to get in.
  • Emergencies. Riley left room for “exigent circumstances,” such as a kidnapped child, someone in imminent danger, or evidence about to be destroyed. Courts decide these case by case.
  • Plain view. If something incriminating is visible on your screen, an officer can act on what they saw.

If an officer searches anyway after you’ve said no, do not physically resist or grab the phone back. Say clearly, “I do not consent to this search,” and let the fight happen later in court. Evidence from an unlawful search can be thrown out. A resisting charge cannot be undone.

Can they make you unlock it?

This is where the law is unsettled, and it turns on how your phone unlocks. The Fifth Amendment protects you from being forced to testify against yourself. Courts argue over whether unlocking a phone counts as testimony.

Unlock method How courts tend to treat it Examples
Passcode or password Usually treated as testimonial (it comes from your mind), so more protected. But some courts allow compelled passcodes when the government already knows you own the phone and know the code (the “foregone conclusion” exception). Utah Supreme Court (State v. Valdez, 2023) protected the passcode. New Jersey (State v. Andrews) and Illinois (People v. Sneed) high courts allowed compelled passcodes.
Fingerprint or Face ID Traditionally treated as a physical trait, like a fingerprint at booking, so less protected. Courts are now split. Ninth Circuit (U.S. v. Payne, 2022): compelled thumbprint was not testimony. D.C. Circuit (U.S. v. Brown, 2025): compelled thumbprint was testimony.

The U.S. Supreme Court has not settled either question. It declined to hear Andrews in 2021, and state high courts are still taking new cases. Ohio prosecutors do file motions asking judges to compel passcodes or biometric unlocks, so don’t assume your state has drawn a bright line in your favor.

Two practical points hold everywhere. First, a request to unlock is just that: you can decline, the same as a request to search. Second, a court order to unlock is different. Refusing one can mean contempt. That is a decision for you and a lawyer, not one to make on the roadside.

Set your phone up before you need it

The time to prepare is now, not when an officer is standing at your window.

  • Use a strong passcode. Six digits at minimum; an alphanumeric password is better. Passcodes get stronger legal protection than biometrics in most courts.
  • Learn your phone’s quick lockout. On an iPhone, pressing and holding the side button with either volume button brings up the emergency screen and disables Face ID until the passcode is entered. Many Android phones offer a “Lockdown” option in the power menu that does the same.
  • Set a short auto-lock time, so the phone isn’t sitting unlocked when it leaves your hand.
  • Turn off lock-screen previews for messages and notifications, so nothing is in plain view.
  • Don’t wipe or destroy anything once police are involved. Deleting data or erasing a phone during an investigation can be charged as a crime on its own.

What to say: a traffic-stop script

Stay calm, keep your hands visible, and keep it short. You don’t need to argue the law with the officer.

  1. When asked for documents: “Here’s my license, registration, and insurance.” (Ohio: give name, address, and date of birth if asked.)
  2. When asked where you’re going or what you’ve been doing: “I don’t answer questions, officer.”
  3. When ordered out of the car: Step out calmly. “I’ll step out. I don’t consent to any searches.”
  4. When asked to search the car: “I don’t consent to any searches.”
  5. When asked to see, search, or unlock your phone: “I don’t consent to a search of my phone, and I’m not going to unlock it.”
  6. If they search anyway: “I don’t consent to this search.” Then stop talking and don’t resist.
  7. If the stop drags on: “Am I being detained, or am I free to go?”
  8. If arrested: “I’m going to remain silent, and I want a lawyer.”

Don’t lie, don’t give a fake passcode, and don’t reach for your phone to lock or erase it once an officer has asked for it. Afterward, write down the officer’s name and badge number, the time and place, and what was said, while it’s fresh.

Special situations

At the border or an international airport. Different rules apply. Under the “border search exception,” Customs and Border Protection can inspect devices without a warrant. You can still refuse to unlock your phone, but the consequences differ by status. U.S. citizens can’t be denied reentry for refusing, though the device may be seized for days or weeks and you may be held for questioning. Green card holders and visa holders can face denied entry. Travel with that in mind.

If you’re recording police. Many federal courts have recognized a right to record officers doing their jobs in public. An officer may still ask for your phone or your footage. You can decline to hand it over, keep a safe distance, and don’t interfere with what they’re doing. Turning on automatic cloud backup protects the video if the phone is taken.

If you’re a witness. Officers sometimes ask a bystander for their phone to see video of an incident. You don’t have to give them the device. If you want to help, offer to send a copy of the file instead, so your whole phone isn’t in someone else’s hands.

The bottom line

Follow lawful orders: stop, hand over your documents, step out if told to. Politely decline everything you’re only being asked to do: answering questions, a car search, a phone search. Say it clearly, say it calmly, and never physically resist. Protect your phone ahead of time with a strong passcode and a quick way to disable face or fingerprint unlock.

This article is general information, not legal advice. Laws vary by state and are changing quickly in this area. If your phone has been seized or you’ve been ordered to unlock it, talk to a criminal defense attorney.
