The Role of Blood Alcohol Content (BAC) in DUI Defense Cases
The Role of Blood Alcohol Content (BAC) in DUI Defense Cases: Thoughts From a DUI Defense Lawyer in Lenexa, KS and Shawnee, KS
Legal Limits for Blood Alcohol Content (BAC) in Kansas
Kansas prosecutors rely heavily on BAC readings as evidence of a DUI offense. A BAC above the legal limit simplifies their case, suggesting the driver was automatically impaired. However, a DUI conviction doesn’t depend just on a BAC test result, and a skilled DUI attorney will analyze both the BAC levels and additional factors to build the strongest possible defense strategy.
How BAC Is Usually Measured

Defending Against BAC Evidence
Challenging the BAC Test’s Accuracy
It is possible for breathalyzer and even blood test results to be inaccurate. Improper calibration of the machines, administration errors, or even certain medical conditions can affect the readings.
Time of Consumption
The BAC level at the time of arrest may not reflect the driver’s BAC level at the time of driving. Alcohol absorption and elimination rates vary depending on factors like weight, food consumption, and metabolism.
Rising BAC Phenomenon
In some cases, a person’s BAC can continue to rise even after they’ve stopped drinking. This “rising BAC” phenomenon can lead to an inaccurate BAC reading if the test is administered too soon after consumption.
Other Defense Considerations
Field Sobriety Test Performance
A BAC test result is not the sole determining factor in a DUI conviction. Another factor often brought up by a skilled DUI attorney is law enforcement’s use of field sobriety tests (FSTs), like the walk-and-turn test or the one-leg stand, to assess a driver’s coordination and balance. However, these tests are subjective and open to interpretation. Factors like age, medical conditions, or even uneven surfaces can impact performance.
Driving Behavior
Traffic violations like reckless driving, swerving, or speeding can support DUI suspicions. However, an attorney will examine all circumstances around the driving behavior. They can explore factors like fatigue, driver distraction, or adverse weather conditions to offer alternate explanations for any driving anomalies.
Circumstances of the Traffic Stop
An unlawful traffic stop is powerful grounds to challenge DUI charges. A DUI defense attorney will thoroughly review the initial reason for the traffic stop to ensure the officer had a valid basis for initiating contact. Any lack of probable cause for the stop could potentially lead to evidence becoming inadmissible.
Miranda Rights Violations
You have the right to remain silent and the right to an attorney. Law enforcement must inform you of these Miranda rights before custodial interrogation. Statements made in violation of your rights may be inadmissible in court, so an attorney will take a careful look at the arrest procedure to identify if there were any violations of your rights.
The Importance of Skilled Legal Representation

Protecting Your Rights
Getting You Through the Court System
Negotiating for a Favorable Outcome
An experienced DUI lawyer can advocate for you to potentially reduce charges, minimize penalties, or negotiate alternative plea deals that protect your driving record and your future. They may have existing relationships with judges and prosecutors, which can smooth negotiations and increase the likelihood of a positive outcome.
Avoiding Long-Term Consequences
The consequences of a DUI conviction can affect the rest of your life, ranging from steep fines to license suspension or even jail time, not to mention higher insurance premiums and a criminal record that may affect employment and other opportunities. An attorney fights hard to minimize these consequences and protect your future. They understand the long-reaching impact of a DUI conviction, and that motivation drives them to fight for the best possible outcome.
While you have the right to represent yourself, the consequences of a DUI conviction are so severe that having a skilled DUI lawyer on your side significantly increases your chances of a successful outcome.
