Frequently asked questions

Can a first-time DWI be dismissed in Texas?

Potential for Dismissal

Absolutely. While a DWI charge is serious, a dismissal is possible under several circumstances. For instance, a case may be dropped if it is demonstrated that the police lacked the necessary probable cause to initiate the original traffic stop.

Technical and Procedural Challenges

Furthermore, the results of field sobriety tests can be challenged and potentially suppressed if they were administered incorrectly or failed to follow strict NHTSA guidelines. Similarly, the prosecution’s case may fall apart if the breath or blood test results are found to be scientifically unreliable due to equipment malfunction or improper handling. Ultimately, each piece of evidence must meet a specific legal standard, and failing to do so can lead to a complete dismissal of the charges.

What is an ALR Hearing and why does it matter?

Understanding the ALR Process

Essentially, an Administrative License Revocation (ALR) hearing is a civil proceeding that remains entirely separate from your criminal DWI case. Importantly, this hearing serves as your primary opportunity to contest the suspension of your driving privileges.

Critical Deadlines

However, you must act quickly, as you have exactly 15 days from the date of your arrest to formally request this hearing. Otherwise, your license will be automatically suspended by the state. Consequently, securing this hearing is a vital first step in protecting your right to drive while your legal case moves forward.

Are blood tests accurate?

The Science of Blood Testing

Technically speaking, blood tests are performed using a process known as gas chromatography. However, the accuracy of gas chromatography relies entirely on validation studies being conducted properly. In fact, many validation studies across Texas fail to account for other volatiles that can be mistakenly measured as ethanol.

The Importance of Proper Separation

Essentially, blood testing is a separation science. Consequently, if the separation of the volatile substances is not executed with precision, the final result becomes unreliable. Therefore, while the technology exists to provide accurate readings, any procedural or scientific oversight can compromise the integrity of the evidence.

Is there anyway to fight a DWI charge?

Challenging Forensic Evidence

In many cases, breath and blood results are not automatically admissible. In fact, specific legal or scientific errors can disqualify them entirely. Furthermore, prosecutors rarely gather the necessary maintenance logs, validation studies, or calibration records on their own. Consequently, this critical data must be obtained independently to ensure the equipment was functioning correctly at the time of the test.

Finding the Path to Acquittal

To address these complexities, The Coffey Firm specializes in analyzing and contesting DWI forensics. Surprisingly, even a seemingly “unwinnable” case may fall apart under close scrutiny. Ultimately, if the technical evidence is found to be flawed, the state often fails to meet its burden of proof, leading to a more favorable outcome.


How to Fight a DWI Charge?

Beyond the forensics mentioned above, here are the primary avenues used to contest a charge:

  • Challenging the Initial Stop: First and foremost, police must have “reasonable suspicion” to pull you over. If it turns out the initial stop was illegal, any evidence gathered afterward—including breath tests—may be suppressed and deemed unusable.

  • Field Sobriety Test (SFST) Validity: Additionally, these tests are highly subjective by nature. For instance, factors like poor lighting, uneven pavement, inner ear issues, or even simple nerves can cause a “fail” in a perfectly sober person.

  • The “Rising Blood Alcohol” Defense: Another key strategy involves the “rising blood alcohol” defense. Because it takes time for alcohol to enter the bloodstream, your BAC might have been below the legal limit while driving, yet rose to an illegal level by the time you reached the station for testing.

  • Chain of Custody Issues: Finally, blood samples must be handled, stored, and labeled with strict precision. Should there be any gap in the “chain of custody,” the results can be rendered unreliable in a court of law.

Can a DWI ruin your life forever?

Broad Legal and Personal Consequences

A DWI can have far-reaching impacts on various aspects of your life. It can jeopardize your immigration status or lead to deportation, and it often results in the loss of your driver’s license or commercial driver’s license (CDL). Furthermore, a conviction may disqualify you from specific personal responsibilities, such as the ability to teach driver’s education to your child.

Professional and Financial Risks

The financial burden of a DWI is significant, often leading to a substantial increase in insurance premiums. Professionally, a conviction can cause immediate job loss or hinder future employment opportunities, depending on your specific industry or role. Beyond the tangible costs, it can also negatively alter how others perceive your character and reputation.

Specialized Defense for Unique Situations

The extent of a DWI’s effects is often specific to the facts of the case and the individual involved. Our primary objective is to evaluate every detail of your situation and do everything possible to help you avoid a DWI conviction and its long-term repercussions.

Are the standardized field sobriety tests scientific?

Law Enforcement Origins

To begin with, it is important to note that Standardized Field Sobriety Tests (SFSTs) were not developed by independent academics or medical doctors. Instead, they were created through a grant from the National Highway Traffic Safety Administration (NHTSA) in coordination with the Southern California Research Institute (SCRI), an organization with close ties to law enforcement. While police had used informal tests for years—such as asking drivers to pick up coins—the SCRI simply formalized these existing methods and developed newer ones in conjunction with officers.

Observations vs. Objective Science

Furthermore, one must understand that these tests are primarily a product of law enforcement rather than a mandate of the law. In fact, they do not function as “pass” or “fail” medical exams. Instead, they are designed to look for specific “cues” that may or may not actually indicate intoxication. Ultimately, because they rely on subjective observation rather than clinical science, their accuracy can be challenged in court.
