Court Procedures for a DUI in Washington State
A DUI arrest can lead to several court appearances before your case reaches a resolution. If you have never faced criminal charges before, the process may seem confusing. You might have a court date but little idea of what will happen when you get there.
Some DUI cases end through negotiations. Others require hearings to challenge evidence or a trial. The steps and timing depend on the charges, the evidence, and the court handling your case.
At the Law Offices of Smith & White, we help clients throughout Tacoma and Pierce County understand the process, prepare for court, and make informed decisions about their defense.
When Will You First Appear in Court After a DUI Arrest?
Your first appearance depends partly on whether police gave you a citation or complaint when they arrested you.
Under RCW 46.61.50571, someone who receives a DUI citation or complaint at the time of arrest generally must appear before a judicial officer within one judicial day. Local court rules may instead provide for an appearance on the earliest practicable day.
If prosecutors file charges later, different scheduling requirements apply. The law generally requires an in-person arraignment as soon as practicable, but no later than 14 days after the next day court is in session following the issuance of a citation or filing of charges.
An arrest does not always mean you will spend the night in jail. Depending on the circumstances, police may release you or hold you for a court appearance.
The court handling your case depends on where the alleged offense occurred and the charges prosecutors file. Tacoma Municipal Court handles misdemeanor DUI cases under city ordinances. Pierce County District Court handles other misdemeanor DUI cases within its jurisdiction, while Superior Court handles felony DUI cases.
Pay close attention to the date and location on your paperwork. Washington requires defendants to attend certain DUI appearances, and missing court can result in serious consequences.
What Happens at a DUI Arraignment?
At arraignment, the court formally advises you of the charges and asks you to enter a plea.
Many defendants plead not guilty while their attorneys investigate the case. A not-guilty plea does not mean you must go to trial. It allows you to review the evidence and consider your options before deciding how to proceed.
The judge may also establish or review conditions of release. Depending on the circumstances, these may include restrictions on alcohol consumption, monitoring requirements, driving restrictions, or bail.
The court considers factors such as prior offenses and public safety when determining appropriate conditions. You must follow any orders the judge imposes while your case is pending.
You also have the right to an attorney. If you cannot afford one, the court will determine whether you qualify for appointed counsel.
How Does Your Attorney Review the DUI Evidence?
Your attorney obtains and examines the prosecution’s evidence through a process called discovery.
Washington’s Criminal Rules for Courts of Limited Jurisdiction, specifically CrRLJ 4.7, govern discovery in misdemeanor cases in municipal and district courts. Upon a proper written request, prosecutors must disclose qualifying evidence within their possession or control, subject to applicable rules and protective orders. Felony cases in Superior Court follow separate criminal discovery rules.
This evidence may include:
- Police reports and witness statements
- Body-camera and dash-camera footage
- Breath-testing records and instrument maintenance information
- Blood-test results and laboratory documentation
- Field sobriety test reports
Your attorney can examine whether officers had lawful grounds to stop and arrest you, whether they followed testing procedures, and whether the evidence supports the charge.
Sometimes the defense needs additional records or expert assistance to evaluate chemical testing. Blood-testing cases, for example, may involve questions about how analysts collected, stored, and tested a sample.
This work can take time, but it often determines which defenses are available and whether the case should proceed to trial.
What Happens at a DUI Pretrial Hearing?
Pretrial hearings allow the judge, prosecutor, and defense attorney to address the case before trial.
The court may review discovery, establish deadlines, consider scheduling requests, and determine whether the parties are ready to proceed. Your attorney may also discuss a possible resolution with the prosecutor.
Some DUI cases require several pretrial hearings. Others resolve after fewer appearances. There is no fixed number of conferences that every case must follow.
Your attorney may request additional time to investigate evidence or prepare a defense. The judge decides whether to grant a continuance under the applicable rules.
Even when little seems to happen during a hearing, your attorney may be reviewing evidence, speaking with witnesses, or negotiating with prosecutors between court dates.
Can Your Attorney Challenge Evidence Before Trial?
Yes. Your attorney may ask the court to exclude evidence that police obtained unlawfully or that fails to meet applicable legal requirements.
These requests often involve motions to suppress evidence.
For example, an attorney may challenge whether an officer had reasonable suspicion for the traffic stop or probable cause for the arrest. Other motions may address the admissibility or reliability of breath and blood testing.
When the parties dispute important facts, the judge may hear testimony from officers or other witnesses. If the facts are undisputed, the judge may decide the legal issues without a separate evidentiary hearing.
Washington’s CrRLJ 3.6 establishes procedures for motions to suppress certain evidence in municipal and district courts.
A successful motion may prevent prosecutors from using important evidence. In some cases, that can lead to reduced charges or dismissal. However, excluding evidence does not automatically end the case.
Can a DUI Case End Without a Trial?
Yes. Many DUI cases resolve through negotiations, although the available options depend on the evidence, criminal history, and other circumstances.
Your attorney may negotiate a reduction in charges or recommend another resolution. Some cases result in amended charges such as reckless driving or negligent driving in the first degree.
Certain defendants may qualify for deferred prosecution under Chapter 10.05 RCW. This treatment-based program can eventually lead to dismissal without a DUI conviction, but it requires years of compliance and the waiver of important trial rights. It is not the same as an ordinary plea agreement.
Reduced charges can carry less severe consequences than a DUI conviction, but they are not necessarily harmless. Under RCW 46.61.5055, certain reduced DUI-related convictions can count as prior offenses if you face another DUI charge.
Your attorney can explain the potential consequences of each option, including effects on your license, employment, and criminal record.
You ultimately decide whether to accept a plea agreement or proceed to trial. The court must also approve any proposed plea resolution.
What Happens if Your DUI Case Goes to Trial?
At trial, prosecutors must prove the DUI charge beyond a reasonable doubt.
Both sides can present evidence, question witnesses, and challenge testimony. Your attorney may examine the officer’s account of the arrest, question chemical test results, or present other evidence supporting your defense.
Defendants facing misdemeanor DUI charges generally have the right to a jury trial. Under CrRLJ 6.1.1, juries in Washington’s municipal and district courts ordinarily consist of six people. A defendant may waive a jury trial in writing with the court’s consent and have a judge decide the case instead.
You have the right not to testify, and the prosecution must prove its case regardless of whether you take the stand.
A trial may result in an acquittal or conviction. In some circumstances, a mistrial or another unresolved outcome may require further proceedings.
Your attorney can explain the risks and benefits of trial based on the evidence and available alternatives.
What Happens After a DUI Conviction?
If you plead guilty or the court finds you guilty, the judge imposes a sentence based on Washington law and the circumstances of your case.
For misdemeanor DUI convictions, penalties may include jail, fines, electronic home monitoring, probation conditions, substance use disorder treatment, and ignition interlock requirements.
The penalties depend on factors such as prior offenses, alcohol concentration, and whether the driver refused an evidentiary breath test.
Washington also expanded its felony DUI law in 2026. Under RCW 46.61.502, a DUI may qualify as a Class B felony when someone has three or more qualifying prior offenses within 15 years or certain earlier DUI-related felony convictions.
Felony DUI cases generally proceed in Superior Court and follow a different sentencing framework.
Your attorney can explain the potential sentence and whether any legally available alternatives apply to your situation.
Does the DOL License Hearing Follow the Same Process?
No. Washington’s Department of Licensing handles administrative license suspensions separately from criminal DUI proceedings.
Under RCW 46.20.308, you generally have seven days after receiving notice to request a DOL hearing challenging a proposed suspension or revocation.
Our guide to Washington DUI hearings explains that process and the issues you can challenge.
