Drivers in Kittitas County, including Ellensburg, Roslyn, and Cle Elum, often ask whether DUI checkpoints are legal in Washington State.

Are DUI Checkpoints Legal in Kittitas County?
No. Washington State prohibits DUI checkpoints, and that includes the cities of Ellensburg, Roslyn, and Cle Elum. In Seattle v. Mesiani, the Washington Supreme Court ruled that sobriety checkpoints violate the right to privacy under the state constitution.
This means officers cannot randomly stop vehicles without reasonable suspicion. Every DUI traffic stop in Kittitas County must be supported by a legal reason, such as a traffic infraction or erratic driving.

DUI Patrols Are Active in Ellensburg, Roslyn & Cle Elum
Even though DUI checkpoints are banned, DUI patrols are very active—especially during holidays, community events, and weekends. Local law enforcement, including the Kittitas County Sheriff’s Office, Ellensburg Police, and Cle Elum-Roslyn Police, regularly look for signs of impaired driving such as:
- Drifting or weaving in a lane
- Speeding or sudden braking
- Rolling through stop signs
- Smell of alcohol or slurred speech
These observations can give officers legal grounds to initiate a traffic stop and begin a DUI investigation.
Know Your Rights During a DUI Stop in Kittitas County
If you’re stopped for suspected DUI in Ellensburg, Roslyn, or Cle Elum, you have important rights under Washington law:
- You have the right to remain silent. You do not need to answer questions about drinking or where you’ve been.
- You can decline field sobriety tests. These roadside exercises are not mandatory and are often subjective.
- You are subject to the Implied Consent Law. Refusing a post-arrest breath test can lead to license suspension and additional penalties—even before conviction.
Protecting your rights begins with understanding them.
