What Happens When You're Arrested for a DUI

Getting arrested for a DUI or DWI sets off two separate legal processes at the same time: a criminal case in court and an administrative license action run by your state's motor vehicle agency. They move on different clocks, use different rules of proof, and one of them almost always has a deadline measured in days, not weeks. Missing that deadline can cost you your license before you ever see a judge, so the single most important thing to do after an arrest is find out that deadline and act on it immediately.

The traffic stop

Police need reasonable suspicion of a traffic violation to pull you over, and reasonable suspicion of impairment to extend that stop into a DUI investigation — the standard from Terry v. Ohio (1968), which allows brief investigative stops based on specific, articulable facts, not a hunch. Some states also use sobriety checkpoints, upheld as constitutional in Michigan Dept. of State Police v. Sitz (1990). During the stop, an officer will typically ask about drinking, watch for signs of impairment, and may ask you to step out for field sobriety tests.

Field sobriety and chemical tests

Field sobriety tests (like walk-and-turn or one-leg-stand) are voluntary in most places; declining is generally not itself a crime, though an officer may note the refusal and use it as part of the basis for an arrest. These roadside physical tests are different from the chemical test (breath, blood, or urine) that implied consent laws address. Under Birchfield v. North Dakota (2016), police may require a breath test as a search incident to a lawful arrest without a warrant, but a blood test generally needs a warrant or valid consent because it's more invasive. The Court also held a state cannot make it a crime to refuse a warrantless blood test, though refusal of a chemical test can still trigger license consequences under implied consent laws that vary by state.

Implied consent means that by driving on public roads, you've already agreed to chemical testing if lawfully arrested for DUI; refusing doesn't stop the process, it just adds its own consequences, which differ from state to state — confirm exactly how yours handles refusal.

Arrest and your rights

If the officer develops probable cause that you were driving impaired, you'll be arrested. Once you're in custody and being questioned about the offense, police must read you your Miranda warnings, per Miranda v. Arizona (1966): the right to remain silent, that anything you say can be used against you, and the right to an attorney, appointed if you can't afford one. Roadside questions asked before arrest generally don't require Miranda warnings, but statements taken during custodial questioning without them can potentially be challenged.

You are never required to explain, justify, or argue your case on the roadside or at the station. Be polite, provide your license, registration, and insurance, and otherwise you can simply say you want to speak with a lawyer before answering questions.

Booking

After arrest, you'll typically be taken to a station or jail for booking: photographs, fingerprints, a record of the arrest, and inventory of your property. Depending on the jurisdiction, you may be released on your own recognizance, released after posting bail, or held until you can see a judge. This is also usually when you'll be formally served with paperwork about the license action described below — read it closely and keep it.

Two tracks, two different clocks

This is the part people miss most often. A DUI arrest almost always opens two separate proceedings that run independently of each other:

• The criminal case. This proceeds through the court system, requires the prosecution to prove guilt beyond a reasonable doubt, and you are presumed innocent throughout. It can take weeks or months and includes arraignment, pretrial motions, possibly trial, and sentencing if convicted.
• The administrative license action. A civil, non-criminal process run by your state's licensing agency, separate from the criminal charge. It can suspend or restrict your driving privileges based on the arrest itself (say, failing or refusing a chemical test) regardless of whether you're ever convicted. It uses a lower burden of proof, and — critically — usually comes with a very short window, often just days from the arrest, to request a hearing and contest the suspension. Miss it, and the suspension can take effect automatically, unchallenged.

Because a conviction isn't required to lose your license administratively, and winning the criminal case later won't necessarily undo a suspension you failed to contest, these two tracks need to be handled as separate priorities from day one.

What to do right after arrest

1. Find the deadline. Check your arrest paperwork for any notice about requesting an administrative license hearing, and note the exact date it's due. Call the issuing agency to confirm the deadline and how to file.
2. Request the hearing immediately if you want to contest the license action, even before hiring a lawyer. In many places this can preserve a temporary permit while the case is pending, but only if you act inside the window.
3. Contact a criminal defense lawyer as soon as possible. Many offer free consultations and can handle both the administrative hearing and the criminal case.
4. Do not discuss the facts of the arrest with police, insurers, or anyone besides your attorney.
5. Gather what you have — citation, release paperwork, witness names, and notes on what happened while it's fresh.
6. Confirm your court date; missing arraignment can result in a warrant for your arrest.

Arraignment

Arraignment is your first appearance before a judge on the criminal charge. The judge states the formal charges, confirms you understand your rights, addresses bail or release conditions, and asks you to enter a plea (commonly not guilty at first, so your lawyer has time to review the evidence). If you cannot afford an attorney, you have a right to have one appointed, guaranteed by Gideon v. Wainwright (1963). You also generally have the right to represent yourself, established in Faretta v. California (1975), though with a DUI charge — where the evidence often turns on test calibration, stop legality, and chain of custody — self-representation carries real risk.

After arraignment, expect pretrial hearings where your lawyer can file motions — for instance, to suppress evidence from an unlawful stop or improperly obtained test — followed by negotiation and, if no resolution is reached, trial. Meanwhile, the administrative license hearing, if you requested one, typically happens separately and much sooner, often before the criminal case is anywhere near resolved. Keep both sets of dates on your calendar; they are not the same, and missing either one has its own consequences.

Building toward a defense

From arraignment forward, a defense lawyer typically examines whether the stop was justified, whether tests were properly administered, and whether the prosecution disclosed all evidence it's required to under Brady v. Maryland (1963). Evidence from an unconstitutional search — say, a blood draw without a warrant or valid consent — can potentially be excluded under the exclusionary rule from Mapp v. Ohio (1961). You also have a right to a speedy trial, weighed under the four-factor test from Barker v. Wingo (1972). None of this substitutes for representation: the facts of your stop, your state's procedures, and the deadlines involved all vary, and a local lawyer who knows your court and state's DUI law is the only one who can tell you exactly how these rules apply.

Key takeaways

• A DUI arrest starts two separate cases: a criminal prosecution and a civil license action, each with its own rules and its own timeline.
• The administrative license hearing deadline is often just days after arrest — find it and request the hearing right away, even before hiring a lawyer.
• You have the right to remain silent and the right to an attorney; use both rather than trying to explain your side to police.
• Refusing a chemical test doesn't stop the process — it carries its own separate consequences that vary by state.
• Being arrested is not the same as being convicted; the prosecution must prove guilt beyond a reasonable doubt, and you are presumed innocent throughout.

Frequently asked questions

Can I lose my license before I'm convicted of anything?

Yes. The administrative license action is separate from the criminal case and is typically based on the arrest and test results, not a conviction. That's why requesting the hearing by its deadline matters even if you're confident about beating the criminal charge.

Do I have to answer questions or perform field sobriety tests?

You're generally not required to answer questions about where you were or what you drank, and field sobriety tests are typically voluntary. Chemical testing after a lawful arrest is different and governed by your state's implied consent law, with its own consequences for refusal.

What happens if I miss the deadline to request a license hearing?

In many states, missing it means the suspension proceeds automatically, unchallenged. Because the window is often very short, call the issuing agency the same day you're released, if possible, to confirm the deadline and how to file.

Will I automatically go to jail after arraignment?

Not necessarily. Many DUI defendants are released on bail, bond, or their own recognizance pending trial, depending on the charge, record, and local practice. Your lawyer or the court can address release conditions at or before arraignment.

Do I need a lawyer for the license hearing, or just the criminal case?

Both proceedings can affect you significantly, and a DUI lawyer can often handle both. Even a brief consultation before the hearing deadline can help you understand what's at stake.
