The officer must have a valid reason to stop you, called "reasonable suspicion." This might include swerving between lanes, driving too slowly or too fast, failing to use headlights, or other traffic violations. Once stopped, the officer will approach your vehicle and ask for your license, vehicle registration, and proof of insurance. At this point, the officer may observe signs they believe indicate impairment, such as slurred speech, the smell of alcohol, or bloodshot eyes.
If the officer suspects impairment, they will typically ask you to perform a preliminary breath test (PBT) using a portable breathalyzer device. In Washington State, you have the right to refuse this roadside test without automatic penalties. This is different from the breath or blood test at the police station, which has different legal consequences if refused.
The officer may also request field sobriety tests (FSTs), which include exercises like the horizontal gaze nystagmus test (following a pen with your eyes), the walk-and-turn test, and the one-leg stand test. These tests are voluntary, and you can decline to perform them. Declining these tests cannot be used against you in court as an admission of guilt.
According to the Washington State Patrol, approximately 25,000 DUI arrests occur annually in Washington. During your stop, remain calm, keep your hands visible, and be polite. Do not physically resist, even if you believe the stop is unjustified. Any resistance can lead to additional charges. You have the right to remain silent beyond providing your license and registration information.
Practical takeaway: Know that roadside breath tests and field sobriety tests are optional. You have the right to decline them without immediate legal consequences at that moment, though refusal may factor into later decisions about your case.
Understanding Blood Alcohol Content Laws in Washington
Washington State has specific legal limits for blood alcohol content (BAC) depending on your age and license type. These limits define what the law considers impaired driving, and understanding them is important for recognizing why you might be arrested.

For drivers age 21 and older with a standard driver's license, the legal limit is 0.08 percent BAC. This means if a breath or blood test shows your BAC at 0.08 or higher, you can be charged with DUI. However, Washington also has an "implied consent" law, which means that by driving on Washington roads, you automatically consent to submit to a breath or blood test if arrested on suspicion of DUI.
For commercial drivers holding a commercial driver's license (CDL), the legal limit is lower at 0.04 percent BAC. For drivers under 21 years old, the limit is even more strict at 0.02 percent BAC. These lower thresholds reflect Washington's strict approach to underage and commercial driving.
Washington State also recognizes "per se" DUI laws. This means that if your BAC is at or above the legal limit, the prosecution does not need to prove you were actually impaired—the BAC level alone is sufficient for a DUI conviction. Conversely, you can be arrested and charged with DUI even if your BAC is below the legal limit if an officer observes signs of impairment from alcohol, drugs, or other substances.
One important point: Washington State considers not just alcohol but also drugs—both prescription and illegal—when determining impairment. An officer might arrest you for DUI based on the observation of impairment from prescription medications, marijuana, or other controlled substances, regardless of your BAC.
According to the National Highway Traffic Safety Administration (NHTSA), driving with a BAC of 0.08 percent increases the risk of fatal crash involvement by approximately 11 times compared to a sober driver. Understanding these legal thresholds helps you recognize the seriousness of Washington's DUI laws.
Practical takeaway: Know your state's BAC limits based on your age and license type (0.08 for adults, 0.04 for CDL holders, 0.02 for drivers under 21), and understand that impairment charges can occur even below the legal limit if an officer observes signs of impairment.

First, you have the right to remain silent. You do not have to answer questions about where you were driving, what you consumed, or other details related to the arrest. Anything you say can be used against you in court. You should clearly state that you wish to exercise your right to remain silent and request an attorney. Once you make this request, police must stop questioning you about the DUI charges.
You have the right to speak with an attorney before answering any questions. If you cannot afford an attorney, you have the right to request a public defender be appointed to represent you. In Washington State, you should make this request clearly and in writing if possible. The state provides public defender services in every county for individuals who meet income requirements.
You have the right to refuse the portable breath test (PBT) at the roadside, as mentioned earlier. However, once at the police station or jail, if arrested, you will be given notice of Washington's implied consent law. This notice explains that refusing the breath or blood test has serious consequences, including automatic license suspension. You still have the legal right to refuse, but refusal itself carries penalties.
You have the right to a blood test instead of a breath test if requested. Some people request a blood test because they believe it may be more accurate or because they want an independent analysis. You can also request that a portion of any blood sample be preserved so that an independent laboratory can test it later.
You have the right to know what you are being charged with and to have that information presented clearly. Within a certain timeframe (typically 72 hours for a misdemeanor), you must be taken before a judge for an initial appearance where charges are explained and bail or release conditions are set.
Practical takeaway: Exercise your right to remain silent, request an attorney immediately, and understand that while you can refuse roadside tests, a refusal of the station breath or blood test triggers automatic license suspension in addition to any criminal penalties.
The Implied Consent Law and Test Refusal Consequences
Washington State's implied consent law is one of the most important legal concepts related to DUI arrests, and it carries significant consequences. When you drive on Washington roads, you are deemed to have given consent to submit to a breath or blood test if a police officer arrests you on suspicion of DUI. This is automatic—you do not sign anything or make an agreement; the law assumes consent simply by driving.

When arrested on suspicion of DUI, officers will inform you of this implied consent law. They will explain that you may choose a breath test or blood test, that you can request an independent test, and that refusing will result in penalties. Despite these warnings, you have the legal right to refuse the test. However, this refusal comes with automatic consequences separate from any criminal DUI charges.
If you refuse a breath or blood test in Washington, your driver's license will be suspended automatically. For a first refusal, the suspension period is typically one year. For a second or subsequent refusal within ten years, the suspension is longer. This suspension occurs regardless of whether you are convicted of DUI. The suspension begins immediately, and you receive a temporary notice to drive.
Additionally, the fact that you refused a test can be used against you in criminal court. Prosecutors may argue that your refusal shows consciousness of guilt—suggesting you refused because you knew your BAC was high. While you have the legal right to refuse, the refusal itself can be evidence in the prosecution's case.
However, there are circumstances where you might have a valid reason to refuse. For example, if you have a medical condition that makes a breath test unreliable, or if you were not properly informed of your rights, an attorney might challenge the refusal. Some people also choose to refuse and fight the implied consent suspension separately from the criminal DUI charges.
