Arlington High BAC DUI Lawyer

DUI with an Alcohol Concentration of .15 or Greater

If you’ve been arrested for DUI in Arlington with an alcohol concentration (often referred to as a blood alcohol concentration or BAC) of 0.15% or higher, you may face enhanced penalties. High BAC DUI charges in Washington carry penalties that are far more severe than those imposed for standard DUI convictions—even for first-time offenders. Jail time, higher fines, and longer license suspensions are all on the table.

At DUIHeroes, we focus exclusively on DUI and related offenses. That means when you hire us, you’re getting a defense team that knows how Washington enforces high BAC DUIs, how prosecutors approach them in Snohomish County, and most importantly—how to fight back.

What Makes DUI a “High BAC” Case in Washington?

It is illegal to operate a motor vehicle with an alcohol concentration of 0.08% or greater, with THC levels exceeding 5.00 nanograms per milliliter of whole blood, or while under the influence of alcohol and/or drugs. 

Under RCW 46.61.5055, DUI penalties increase if:

• Your alcohol concentration result was 0.15% or greater, or
• You refused a breath or blood test.

Even a first offense at this level comes with mandatory minimum penalties that can include:

• At least 2 days in jail (or 30 days of electronic home monitoring)
• One-year license revocation through the Department of Licensing (DOL)
• A fine of $500 to $5,000
• Mandatory installation of an ignition interlock device (IID) after license reinstatement

Prior DUI offenses, accidents, or aggravating factors (such as having a passenger under 16 in the vehicle) may increase these penalties further. These penalties represent real risks to your freedom, career, and future. That’s why putting a dedicated Arlington high BAC DUI lawyer on your side is so important.

Breath & Blood Tests to Determine BAC

In Washington, BAC is measured primarily through breath and blood testing, both of which come with their own flaws and procedures. Breath tests, often administered on Dräger breath test devices at the station, rely on machines that must be carefully maintained, calibrated, and operated correctly. Even small errors in handling or machine maintenance can produce inaccurate results. Blood tests, on the other hand, are typically used when drugs are suspected or when breath testing isn’t possible. These tests require a strict chain of custody and adherence to lab protocols to be admissible in court. Officers must also request a warrant to perform a blood draw.

While prosecutors often present BAC results as irrefutable, they are anything but. At DUIHeroes, our attorneys are trained to the same NHTSA standards as the officers who conduct field sobriety tests. Founding attorney Jonathan Dichter is not only a qualified instructor in standardized field sobriety testing but also a national educator in DUI defense. That level of training gives us the ability to scrutinize every step of the testing process, from the initial administration to the final reporting, exposing errors or inconsistencies that could significantly alter the outcome of your case.

Defense Strategies for High BAC DUI in Arlington

When the state claims your BAC was 0.15% or higher, it may sound like a slam-dunk case. It isn’t. These results can—and often should—be challenged. 

At DUIHeroes, we may build your defense by:

• Questioning the Stop: Was there probable cause to pull you over in the first place?
• Challenging the Test Results: Were the breath testing devices calibrated properly? Was the blood test handled according to protocol? Was the test performed precisely as it should have been?
• Highlighting Medical Conditions or External Factors: Acid reflux, diet, medical conditions, and other circumstances can influence the outcome of a test result. We consider every possibility.
• Cross-Examining Officers & Experts: Our knowledge of sobriety testing means we can expose flaws in officer testimony, machine calibration, or laboratory evidence.

Because our attorneys include two former prosecutors, we also understand how the other side thinks. That insight helps us anticipate their arguments and prepare stronger defenses.

The Right Choice for High BAC DUI Defense

When you’re accused of driving with a BAC of 0.15% or higher, prosecutors will fight for the harshest penalties available. That’s why it’s critical to have a team with both the training and experience to challenge the state’s case. At DUIHeroes, DUI defense is not a side practice—it’s our entire focus. With more than 50 years of combined experience, our team brings a depth of knowledge that allows us to anticipate and counter the prosecution’s tactics at every turn.

We also match and often exceed the training of law enforcement. Every one of our attorneys has completed the NHTSA DWI Detection and Standardized Field Sobriety Testing course, the same course required of officers in Washington. Jonathan Dichter goes further still as a qualified instructor and lecturer on DUI defense strategies, ensuring our firm remains on the cutting edge of developments in this field.
