Seeing flashing lights in your rearview mirror triggers a stress response for almost everyone — even people who haven't done anything wrong. That stress makes it easy to say or do things that create problems you didn't have when you were first pulled over.
A traffic stop is a legal encounter. What you say, what you do, and what you don't do all have real consequences. Here's a clear-eyed guide to handling a traffic stop in Missouri.
What to Do Immediately When You See the Lights
Pull over promptly and safely. Signal your intent, move to the right, and stop as far off the road as safely possible. If you're on a highway and it's dark, you may slow down and drive to the next well-lit area — courts have accepted this. But don't drive for miles; find a safe spot within reason.
Once stopped:
- Turn off the engine
- Turn on your interior light if it's dark
- Keep your hands visible — on the steering wheel is ideal
- Don't reach for your glove box or under the seat until asked, and tell the officer what you're doing before you reach ("My registration is in the glove box — may I get it?")
What You Are Required to Provide
Missouri law requires you to provide three things when stopped by law enforcement:
- Your driver's license
- Your vehicle registration
- Proof of insurance
That's it. You are not required to tell the officer where you've been, where you're going, whether you've been drinking, or anything else. Be polite, but be clear: "I'd prefer not to answer questions without an attorney."
Your Right to Remain Silent
The Fifth Amendment protects you from being compelled to incriminate yourself. This right applies at a traffic stop. You can decline to answer questions beyond providing your identifying information. Politely exercising this right is not obstruction — it is constitutionally protected conduct.
The most common mistake people make during traffic stops is talking too much. Voluntary statements — "I only had two beers," "I was just running a little late," "I didn't know the light was red" — can be used against you in court. An officer who has decided to arrest you is not going to change their mind because of your explanation. And an officer who hasn't decided yet may use your words to justify an arrest they otherwise wouldn't have made.
Search of Your Vehicle
You do not have to consent to a search of your vehicle. If an officer asks, "Do you mind if I take a look in your car?" — that is a request, not a command. You can say: "I do not consent to a search."
However, consent is not the only way police can search your car. Officers can search without consent if they have probable cause — articulable facts suggesting evidence of a crime is present. The smell of marijuana (even in legal quantities in many contexts), visible open containers, or other observable facts can give an officer probable cause. Your refusal to consent doesn't prevent a probable cause search, but it matters legally because it preserves your right to challenge the search in court.

Talk to Chris Miller →Missouri's Implied Consent Law
Under RSMo § 577.020, anyone who drives on Missouri roads has implicitly consented to chemical testing — breath, blood, or urine — if a law enforcement officer has reasonable grounds to believe they are driving under the influence.
Refusing a breathalyzer or blood test triggers an automatic one-year license revocation by the Missouri Department of Revenue — separate from and in addition to any criminal DWI charge. A first-offense DWI conviction typically carries a 30-day suspension. So refusing often costs you more license time than cooperating would. This is a complicated calculus that an attorney can help you think through after the fact, but at the moment of the stop, refusing has serious automatic consequences.
If You Are Arrested
If the officer places you under arrest: don't resist, don't argue, don't try to talk your way out of it at the scene. Anything you say after arrest is also admissible. The time to contest the arrest is in court — not on the side of the road.
Once arrested, clearly invoke your right to counsel: "I want to speak with an attorney." After that, say nothing further until you have had a chance to consult with a lawyer. This applies even if the officer seems friendly, even if they say talking to you will help your case, and even if you feel like explaining yourself would clear everything up.
After the Stop: What to Do Next
Write down everything you remember as soon as possible — what the officer said, what you said, what was searched, what was found. Details fade quickly. If you received a citation, note the court date and contact an attorney before that date. If you were arrested, contact an attorney as soon as possible — time-sensitive administrative steps may be needed to protect your driving privileges.
