A DUI case proceeds along two parallel tracks: a criminal case in court and an administrative case at the DMV. Each has its own deadlines, hearings, and consequences. Missing a single deadline — particularly the 10-to-30-day DMV hearing request — can cost you your license before the criminal case is even heard.
1. Traffic Stop & Field Sobriety Tests
An officer needs 'reasonable suspicion' of a traffic violation or impairment to stop you. Field sobriety tests (FSTs) are voluntary in nearly every state, and refusal cannot be used as evidence of guilt at trial. The officer is also evaluating your speech, eyes, balance, and the smell of alcohol throughout the encounter.
2. Arrest & Chemical Test
If the officer establishes probable cause, you are arrested. Implied-consent laws then require you to submit to a post-arrest breath, blood, or urine test. Refusal triggers automatic license suspension (longer than a DUI suspension in many states) and can be used against you at trial.
3. Booking & Release
You are transported to jail, fingerprinted, photographed, and held in a holding cell for 4–12 hours until released on bail, on your own recognizance, or to a sober adult. Your vehicle is impounded — recovery typically costs $200–$500.
4. DMV Hearing — 10-to-30-Day Deadline
You must request an administrative DMV hearing within 10 to 30 days (varies by state) to contest the automatic license suspension. This is separate from the criminal case and uses a lower burden of proof.
Missing this deadline forfeits your right to contest the suspension entirely. Always calendar this date the day of arrest.
5. Arraignment
Your first court appearance, usually within 30–60 days of arrest. The charges are formally read, you enter a plea (typically not guilty at this stage), and bail conditions are set. Most defendants are not required to attend if represented by counsel.
6. Pre-Trial Motions & Discovery
Defense counsel obtains the police report, dash-cam and body-cam video, breathalyzer maintenance and calibration records, and any blood-test laboratory documentation. Motions to suppress evidence — based on an unlawful stop, Miranda violation, or chemical-test irregularities — are filed here.
Most dismissals and reductions happen at this stage, not at trial.
7. Plea or Trial
Most criminal cases in the United States resolve by plea rather than trial. The Bureau of Justice Statistics' State Court Processing Statistics series found that roughly nine in ten convictions in state felony courts came from guilty pleas; DUI-specific rates are not tracked nationally and vary by county. Where a case does go to trial, a misdemeanor DUI jury or bench trial commonly lasts one to three days.
8. Sentencing
Upon conviction or guilty plea, the court imposes a sentence: fines and court costs, jail or probation, license suspension, ignition interlock device, mandatory DUI school or treatment, community service, and possible vehicle impoundment. The DMV implements its own license actions in parallel.
Frequently Asked Questions
How long does a DUI case take?
Most cases resolve in 3–6 months from arrest to sentencing. Trials and complex motion practice can extend cases to 12 months or more.
Do I need a lawyer for a DUI?
You have a right to counsel, and one may be appointed if you cannot afford one. DUI procedure is technical and the deadlines are short, which is why most defendants are represented. Whether to retain counsel is your decision; this page is general information, not legal advice.
What is the DMV hearing deadline?
Usually 10 days from arrest in most states (up to 30 in a few). Missing the deadline forfeits your right to contest the automatic license suspension.
Can I refuse the breath test?
Yes, but every state's implied-consent law triggers automatic license suspension and additional penalties. Refusal can also be used as evidence of consciousness of guilt at trial.
What happens at arraignment?
The judge reads the charges, you enter a plea (almost always 'not guilty' at this stage), and bail conditions are set. Most attorneys appear on your behalf so you do not need to attend.
