Many drivers assume that as long as their breathalyzer test reads under the legal threshold of 0.08%, they are safe from a drunk driving arrest. However, if you are stopped by law enforcement and need guidance from a DUI Lawyer in Everett, WA, you may be surprised to learn that a low breath test result does not automatically protect you from criminal charges.
Understanding how Washington state laws operate can help you protect your rights and take the correct steps following a traffic stop.
The Legal Standard: Understanding "Affected By" Intoxicants
Washington law governs driving under the influence under Revised Code of Washington (RCW) 46.61.502. While blowing a 0.08% or higher allows prosecutors to pursue a "per se" DUI charge based solely on the chemical calculation, the statute contains another critical legal path known as the "affected by" prong.
Under this provision, you can still face charges even with a lower BAC reading if the state claims your driving was impaired:
Per Se DUI: Based strictly on chemical test results meeting or exceeding the 0.08% limit.
Affected By DUI: Based on whether your physical or mental capabilities were appreciably impaired by alcohol, drugs, or a combination of both.
How Officers Build a DUI Case Below 0.08
When a breath alcohol test returns a result below 0.08%, officers shift their focus from chemical numbers to physical observations. Prosecutors rely heavily on subjective evidence to try to prove impairment:
Physical Appearance: Reports describing slurred speech, bloodshot or watery eyes, flushed skin, or unsteadiness.
Standardized Field Sobriety Tests: Observations made during physical coordination tests, such as the walk-and-turn or one-leg stand.
Polydrug Use Allegations: Claims that combining small amounts of alcohol with prescription medications, over-the-counter drugs, or cannabis created an intoxicating effect.
Driving Behavior: Traffic infractions such as drifting between lanes, swerving, braking abruptly, or speeding.
Real-World Penalties for Low-BAC DUI Arrests
A DUI arrest involving a breath test below 0.08% still carries life-altering consequences that require immediate attention:
Court Consequences: Potential jail time, heavy criminal fines, mandatory probation, and required alcohol evaluation classes.
Administrative License Suspensions: The Washington Department of Licensing (DOL) can move to suspend your driver's license independently of criminal court outcomes.
Long-Term Impacts: Permanent criminal records, increased auto insurance premiums, and potential disruptions to current or future employment.
Scientific Defenses Against Low-BAC Charges
Defending a case where the breath test fell below 0.08% requires a detailed, forensic approach that challenges officer assumptions with concrete evidence. Key defense strategies include:
Challenging Field Sobriety Tests: Demonstrating how anxiety, poor road conditions, physical injuries, or improper instructions skewed test results.
Analyzing Medical Factors: Proving that conditions such as fatigue, allergies, or naturally occurring medical issues mimicked signs of intoxication.
Scrutinizing Breathalyzer Equipment: Reviewing maintenance logs, calibration records, and test administration protocols for potential technical errors.
