A BAC reading of 0.20% or above stops prosecutors in their tracks—in a good way for them. They see a number that shocks juries. A number more than twice the legal limit. A number that suggests dangerous intoxication. They build their entire case around that number, expecting you to plead guilty and accept whatever sentence they recommend.
But extreme readings deserve extreme skepticism. At 0.20% BAC, most people can barely stand. They slur words. They stumble. They’re visibly, obviously intoxicated. If the arresting officer’s report describes you walking to your car, answering questions coherently, or performing field sobriety tests without falling over—something doesn’t add up. Either you weren’t actually at 0.20%, or the machine got it wrong.

Why Choose Eastside DUI For .20 BAC DUI Defense In Bellevue, WA?
We Question Numbers That Don’t Make Sense
Prosecutors love extreme BAC readings. Juries gasp at them. Judges shake their heads. But experienced DUI defense attorneys ask a different question: does this number match what actually happened?
At genuine 0.20% intoxication, people exhibit profound impairment. Severe motor dysfunction. Confusion. Difficulty with basic tasks. If dash cam footage shows you stepping out of your vehicle without stumbling, if the officer’s narrative describes responsive answers to questions, if you completed field sobriety tests—even poorly—without collapsing, then either you have superhuman alcohol tolerance or the breath test result is wrong.
Roberto Yranela has defended clients with extreme BAC readings since 2013. He’s learned to look beyond the number to the full picture. His undergraduate training at the University of Washington included psychology—helpful for understanding how officers interpret behavior through the lens of an expected outcome. His J.D. from Valparaiso University School of Law provided the legal framework for translating behavioral inconsistencies into courtroom arguments.
Recognized DUI Defense Practice
Super Lawyers recognized Roberto Yranela as Top 40 Under 40 for DUI defense. Avvo honored him with Client’s Choice recognition. The National Trial Lawyers named him to their Top 40 Under 40. When you need a DUI attorney in Bellevue who won’t be intimidated by a shocking number on a police report, our track record shows we take on these cases—and challenge them effectively.
Extreme Numbers Create Extreme Opportunities
Here’s what most defendants don’t realize: the higher the BAC reading, the easier it becomes to demonstrate that something went wrong. Moderate readings are harder to challenge because the observed impairment matches expectations. Extreme readings often contradict what officers actually witnessed. That contradiction becomes your defense.

Types Of .20 BAC DUI Cases We Handle In Bellevue
Extreme BAC cases vary based on circumstances, prior history, and how the reading was obtained. Our DUI defense attorneys handle all variations.
- First offense at .20 BAC or above. Even without prior history, readings this high draw maximum prosecutor attention. Enhanced penalties apply. Judges consider the extreme number when setting bail conditions and ultimately sentencing. A Bellevue DUI lawyer challenges both the reading itself and the assumption that it proves extreme danger.
- Repeat offense with extreme BAC. Prior DUI convictions combined with .20+ readings create compounding exposure. Prosecutors seek maximum sentences. Judges have little patience. But the same testing problems that affect any breath test affect these readings too—and challenging them matters even more when facing months of mandatory jail time.
- Readings that contradict behavior. When officer observations don’t match extreme BAC levels, we build defenses around that disconnect. Challenging breathalyzer results becomes particularly powerful when jurors can watch video of someone walking steadily despite supposedly being at 0.22% BAC.
- Accident cases with high BAC. Collisions combined with extreme readings create the prosecution’s ideal case—on paper. But accident causation is separate from intoxication level. Road conditions, other driver behavior, mechanical issues—all remain relevant regardless of what the breath test showed.
- Blood test cases. Some extreme readings come from blood draws rather than breath tests. Blood testing has different vulnerabilities—fermentation in improperly stored samples, contamination, chain of custody issues. Knowing your rights after arrest includes understanding how blood evidence can be challenged.
- Medical condition cases. Certain conditions produce acetone or other compounds that breath machines misread as alcohol. Diabetic ketoacidosis can generate readings suggesting extreme intoxication in someone who consumed little or no alcohol. These cases require medical documentation and specialist testimony.
Washington Legal Requirements For Extreme BAC DUI
Washington law applies the same enhanced penalty threshold—0.15% BAC—regardless of how far above it you test. But extreme readings affect how prosecutors, judges, and juries perceive your case even when the formal legal consequences remain capped.
Under RCW 46.61.5055, BAC at or above 0.15% triggers enhanced mandatory minimums. Whether you tested at 0.15% or 0.25%, the statutory minimums are identical:
First offense with enhanced BAC: 2 days minimum jail, fines from $1,195.50 to $5,000.
Second offense within seven years: 45 days minimum jail, fines from $1,545.50 to $5,000.
Third offense within seven years: 120 days minimum jail, fines from $2,545.50 to $5,000.
However, judges retain discretion within statutory ranges. A reading of 0.16% might result in a sentence near the minimum. A reading of 0.24% often pushes judges toward the maximum. The number influences outcomes beyond the formal enhancement structure.
The Washington State Patrol maintains breath testing protocols that apply equally to all readings. Calibration requirements don’t change based on result magnitude. Operator certification standards remain constant. A DUI lawyer in Bellevue holds the state to these standards regardless of how high your reading appears.
The Washington Department of Licensing imposes administrative consequences tied to BAC level. Extreme readings can affect ignition interlock duration, license reinstatement conditions, and treatment requirements. A Bellevue DUI attorney addresses both criminal prosecution and administrative proceedings with coordinated strategy.
Challenging Extreme .20 BAC Readings In Bellevue
A Bellevue .20 BAC DUI lawyer attacks extreme readings through strategies that leverage the very extremity prosecutors rely on:
- Behavioral disconnect analysis. We obtain every piece of evidence showing your actual condition—dash cam footage, body cam recordings, booking video, officer narratives. When these show someone functioning far better than 0.20%+ intoxication would permit, jurors question whether the machine told the truth. Our drunk driving defense team presents this contradiction as the centerpiece of defense.
- Tolerance arguments. Chronic alcohol users develop tolerance that allows function at BAC levels that would incapacitate others. This cuts both ways—it might explain why you could walk at 0.20%, but it also raises questions about the accuracy of tolerance assumptions built into breath testing. We use this complexity to create doubt.
- Mouth alcohol amplification. Small amounts of residual mouth alcohol produce larger apparent errors at higher readings. The multiplicative effect means contamination that might add 0.02% to a low reading could add 0.04% or more to a high one. Knowing what to avoid saying matters for your statements, but what happened physically before the test matters for the reading itself.
- Radio frequency interference. Breath testing instruments can be affected by nearby electronic devices, police radios, and other RF sources. At extreme readings, small percentage errors translate to large absolute errors. A 5% instrument error on a 0.20% reading equals 0.01%—enough to question reliability.
- Partition ratio extremes. Individual breath-to-blood ratios vary from roughly 1300:1 to 3000:1. The machine assumes 2100:1. Someone at the low end of the range who actually has 0.14% blood alcohol could register 0.20% or higher on the breath test. This isn’t theoretical—it’s documented physiological variation.
- Rising BAC compounded. Alcohol absorption continues after drinking stops. If you consumed alcohol shortly before driving, your BAC while operating the vehicle may have been dramatically lower than when tested at the station. At high readings, the gap between driving BAC and testing BAC can be substantial—potentially the difference between 0.12% while driving and 0.20% thirty minutes later.
- Machine-specific history. We subpoena complete maintenance records for the instrument that tested you. Past repair issues, calibration drift patterns, previous anomalous readings—any history suggesting unreliability supports challenging your specific result. Working with a DUI defense attorney who knows what records to request and how to interpret them transforms raw data into courtroom arguments.
