How a Washington DUI Case Works

If you've been charged with a DUI in Washington, your case will likely follow a predictable process. It begins with police contact. It can either end in a dismissal, acquittal, or some form of conviction and sentence.

Although there are endless scenarios and no two cases are alike, many of the issues in a DUI case are common. This page is designed to help walk you through a "typical" case so you can get a birds-eye view of a DUI case and understand how the process works, start to finish. While each of these phases will seem routine to a seasoned DUI lawyer, they will all seem strange and potentially scary to you.

But by reading this page, you can gain better understanding of the process. With this information, hopefully the entire process will seem less scary. Because in the end, being scared won't help you beyond hopefully helping you think twice before putting yourself in a position where you could be charged with another DUI.

DUI Stop and Arrest

During a DUI investigation, the legal treatment of a question, answer, or silence depends on custody, interrogation, warnings, invocation, and the proposed evidentiary use. A person must comply with lawful directions and provide driving credentials required by law, but the page should not present one scripted response as the only legally acceptable answer or promise that silence can never carry an evidentiary dispute.

Field Sobriety Tests

After making initial observations and asking you questions, an officer may ask you to do field sobriety tests. In a DUI, field sobriety tests are designed to test your ability to follow instructions and do basic mental and physical tasks. The theory goes, if you can't properly do these tests correctly, you may be impaired.

Although the field sobriety tests are admissible at a later trial, they are not an exact science. Often, officers give the wrong instructions or fail to give all of the instructions. Sometimes these tests are recorded and sometimes they are not.

If you refuse to do the tests, the fact that you refused may be used at trial against you. To be clear, the field sobriety tests usually include dozens and dozens of instructions. Most people underestimate what is being asked of them.

It is not uncommon to think, they just want to know if I can walk down a line and back. So long as I don't fall down, I'm good to go. In fact, the field sobriety tests test for much smaller things.

The tests are designed to see if you raise your arms for balance, whether you touch your heel to your toe when walking, whether you take the exact number of steps requested, and whether you take the turn exactly as instructed. Field sobriety tests are much closer to a dance competition than you think.

You will get docked for things you didn't think were important, because the instructions are often not clear on what is expected of you and what is being given weight. Don't be afraid to ask lots of questions before the test. Don't be afraid to ask for the instructions to be provided to you multiple times before starting.

Also, don't be afraid to ask that the tests be recorded. You can even ask to have them recorded for posterity. Then if the officer says you refused to do the test, you can simply explain that you were willing to do the tests if there was going to be an accurate record of your results, rather than just the officer's recollection.

As time goes by, body cams and dashcams in police investigations become more and more common, however, they aren't used by every agency yet. There is nothing wrong in requesting that the police investigation be accurately recorded. It might protect you.

The Portable Breath Test

A portable breath test is a roadside screening device, not the evidentiary breath instrument used after arrest. In State v. Smith, the Washington Supreme Court held that a result from an unapproved PBT was inadmissible absent state-toxicologist approval or a scientific-reliability showing.

PBT evidence can still create issues in a probable-cause hearing, and admissibility depends on the device, foundation, and purpose. The page should not promise that every PBT result will be excluded or describe every device as less accurate without an identified source.

Post Arrest Draeger Breath Test

If you are arrested for DUI, you will be taken down to the station and asked to take a formal Draeger breath test. You will also be advised of your Miranda warnings and asked a series of questions to help build a case against you. The most important thing to do at this point is request to talk to an attorney.

Right to an Attorney

CrRLJ 3.1 provides that a person in custody who wants a lawyer must, at the earliest opportunity, receive access to a telephone, the public defender's number, and other means necessary to communicate with a lawyer. Whether police provided a reasonable opportunity is fact specific. The rule does not support advice to demand unlimited calling time or a promise that police must delay every procedure until a particular lawyer answers.

Implied Consent Warnings for Breath

You will also be advised of your implied consent warnings. Under Washington law, no breath test is admissible unless you were first advised of your right to refuse the breath test. You will also be advised that there are certain downsides to refusing a breath test, including a longer license suspension.

You are allowed to ask questions about these warnings. If they are confusing, do not sign the form until you've had a chance to ask questions. You can also insist on talking to an attorney about the implied consent laws.

Independent Testing

RCW 46.61.506 permits a tested person to obtain one or more additional tests from a qualified person of the person's choosing. An additional test may be admissible if the required foundation is established. The statute also says that failure or inability to obtain an additional test does not by itself bar the State's test.

The page should describe the right to seek additional testing without promising police-funded testing or transportation in every case.

After Being Charged with DUI

Do not delay in consulting with a lawyer. Vancouver WA DUI lawyer Roger Priest is available for a free consultation every day of the week. The longer you wait, the greater the chance that you might miss a vital step.

Even if you aren't sure whether you can afford an attorney, it pays to schedule a free consultation, just to get your questions answered. A DUI lawyer can help you take control of your destiny and empower you to get ahead of the charges. Once on the case, a DUI lawyer can help you mitigate the circumstances and help negotiate on your behalf.

I've yet to meet a client yet who wishes they would have handled their DUI alone. The process is scary and foreign, so it pays to have an expert in your corner.

DUI License Suspension

A request for a DOL hearing generally must be made within seven days after the applicable notice is given. In a breath-test or refusal case, the officer ordinarily serves the notice; after a blood test, DOL may give notice later after receiving the result. The notice controls the deadline, so the person should review it immediately.

What Our Clients Say About Us

I hired Roger to represent my husband when he was arrested on false charges. From the very beginning, Roger was responsive, knowledgeable and willing to take on the case. He was the only one to return my call when I was searching for help. He is very confident in his ability and worked hard to get all the charges dismissed. He is able to be calm in situations where his clients are anything but. I am so grateful for the services provided by Roger. He is very respected in the legal community here in Vancouver. I hope I never need a lawyer again, but if I did, Roger would be my first choice.

I am writing a much overdue review for Roger Priest after he has gone above and beyond while representing me as my lawyer. Last year I found myself facing legal difficulties after my first and only DUI. While the circumstances were incredibly stressful, Roger's involvement in my case made the process straight forward and my case was resolved in a timely manner. Roger is exceptionally proficient in cases like mine and he demonstrates that in and out of the court room. Not only did he walk me through the process but he put my family's concerns at ease by answering all of our questions and making himself available whenever we needed clarification. I was very fortunate to have Roger on my side during that difficult time and would highly recommend his services to anyone that finds themselves in need of legal counsel. Thank you once again, Roger!

I met Roger at the start of 2025, somehow after I paid for a fender bender that I caused I was hit with a hit and run little did I know when I had a warrant two years after the incident. As of today my case was entirely dismissed without even going to trial. I couldn't be happier with the results and couldn't vouch for a different lawyer. Every time we had a court date, we were the first ones on and promptly the first case handled. Roger Priest is the man- I would highly recommend you give him a call if you are experiencing trouble.

Had a consultation with Roger priest this morning, paid attention to detail and what he had to say and he was very honest and upforward not to mention he took the time to look up additional information which lead to the best possible news. I thought my life was over and he gave me hope. Thank you Roger I will be hiring you!!! You give people with a bad past who are trying to do good lots of hope! God bless you.

Roger handled my case promptly and painlessly. We are from out of state and had spoken with quite a few attorneys in the area before we made the trip. Roger was middle of the road cost-wise (which was truly fair) and was clearly competent, handling the case in one trip over as oppose to the two or even three trip process many of the others were communicating would be the case. I would hire again without a second thought. Thanks again Roger.

Roger Priest provided truly exceptional service for a family member of mine. He was an extraordinary value for the level of knowledge and proffessionalism he provided. My loved one got the deal of a lifetime thanks to him. If any of my friends or family are ever in a less than fortunate spot and need legal advice Roger will always be my #1 reccomendation.

Roger Priest is professional, intelligent and experienced, you can tell by the way he holds himself in court. Out of the 21 lawyers I interviewed and compared on an excel spreadsheet. I put my trust in Roger and he didn't let me down.
AM Aaron M 7 months ago
Roger Priest was my Criminal Attorney for a DUI case I had in 2018. Through out the whole process he was in contact and always was reassuring! He gave his honest opinion on rather or not if my case would be worth going to trial, which is hard to come by! Today I left the courtroom a free man to come home to my family with a lot of tension lifted off my shoulders because of how he was articulate and presented my defense. I am very lucky to have him in my corner and to be spared. I will take this experience as a wake up call because these opportunities don't come too often! Mr. Priest definitely deserves a 5 star rating for his devotion and overall performance.
JB JB 8 months ago
Roger Priest was referred to me by another lawyer (who could not take my case). Out of the 3 lawyers I reached out to Mr. Priest was willing to hear my case and not just try and convince me to take the easy route and plead out. He was informative, honest, and very tactical (in his approach with my case). Mr. Priest not only kept me updated with his plans and what to except he involved me in every aspect I could be in. He was very approachable and kind. I won my case, I wouldn't have if I had gone with another lawyer. I am very satisfied with having had Roger Priest defend me. I hope to never have to use his services again but definitely would rehire him again (I wish I could hire him as my divorce attorney).
AS Alicia S. 6 months ago
I recently consulted Roger for my first and only legal matter. He explained at length the legal ramifications that i was facing and he listened closely to all my questions and concerns. He was very attentive and empathic towards my situation and did not rush through things. I would highly recommend Roger to anyone I know seeking legal representation.

FAQ

Common DUI Process Questions

Do I have to take field sobriety tests?

No, they are voluntary, though refusing them can be used against you in court.

Is a roadside breath test the same as the one at the station?

No. A portable breath test is a roadside screening device, not the evidentiary breath instrument used after arrest. Admissibility depends on the device, foundation, and purpose, and PBT evidence can still create issues in a probable-cause hearing.

How long do I have to challenge my license suspension?

A request for a DOL hearing generally must be made within seven days after the applicable notice is given. In a breath-test or refusal case, the officer ordinarily serves the notice; after a blood test, DOL may give notice later after receiving the result. The notice controls the deadline.
