Request A free Consultation

Federal Way DUI Attorney


Driving under the influence (DUI) is one of the most consequential crimes in Washington State. Not only do you face a criminal charge that can send you to jail and follow you permanently on your record, but you also face an administrative case that can suspend your license. In these situations, you need an attorney who can defend you on both fronts.

Mark S. Treyz has defended drivers in Washington courts for decades. If you were arrested on suspicion of DUI, we will aggressively protect your rights through every stage of your criminal case. Call The Law Offices of Mark S. Treyz at (253) 272-8666 to speak with a Federal Way defense lawyer. Schedule your free case evaluation today.

Why Trust The Law Offices of Mark S. Treyz with Your DUI Case?

  • Mark Treyz has handled thousands of criminal cases, first as a Pierce County Deputy Prosecutor and then as a defense attorney. He has defended impaired driving cases in courtrooms throughout Washington, including Federal Way Municipal Court.
  • No two DUI cases are alike, so we build your defense around the facts of yours: the reason for the stop, how the roadside tests were run, and what the breath or blood analysis actually shows.
  • Your financial situation should not determine the quality of the DUI defense you receive. We offer flexible payment plans designed to fit your budget. 

What Is Considered a DUI in Washington State?

Washington’s DUI statute, RCW 46.61.502, defines driving under the influence as follows:

(1) A person is guilty of driving while under the influence of intoxicating liquor, cannabis, or any drug if the person drives a vehicle within this state:

(a) And the person has, within two hours after driving, an alcohol concentration of 0.08 or higher as shown by analysis of the person’s breath or blood made under RCW 46.61.506; or

(b) The person has, within two hours after driving, a THC concentration of 5.00 or higher as shown by analysis of the person’s blood made under RCW 46.61.506; or

(c) While the person is under the influence of or affected by intoxicating liquor, cannabis, or any drug; or

(d) While the person is under the combined influence of or affected by intoxicating liquor, cannabis, and any drug.

A Federal Way DUI Attorney Protects Your Rights and Your Freedom

A DUI conviction in Federal Way can carry hefty consequences. A first offense is a gross misdemeanor, punishable by up to 364 days in jail and a $5,000 fine, with mandatory minimums that rise alongside your test result and your record. Four or more prior offenses in ten years, or a past vehicular assault or vehicular homicide involving impairment, can push the charge to a felony.

With your license, your livelihood, and your liberty on the line, you need an attorney who will fight for your side of the story. The Law Offices of Mark S. Treyz examines whether the officer had lawful grounds to stop you and whether your rights are protected. We will leverage every possible piece of evidence to build a compelling defense in your favor.

Steps to Take in the Hours and Days Following a DUI Arrest

If you are arrested on suspicion of DUI, stay calm and remain silent. Give the officers your name and identifying information, follow their instructions, and do not argue at the roadside or at the station. Beyond that, answer no questions. Say plainly that you want an attorney, and then stop talking. Your lawyer will speak for you from that point forward, handling conversations with the police and the prosecutor.
