Alcohol Breathalyzer Test
DWI Defense Attorney — Houston, Galveston, League City, Texas
Don’t believe in the myth that refusing to submit to an alcohol Breathalyzer test is an automatic admission of guilt in Texas.
The truth is this: refusal of a Breathalyzer may end up in license suspension, however you still have the opportunity to be have Houston criminal attorney Tad Nelson corner dispute the suspension of your Texas Drivers License in the court. This opportunity comes at a hearing which would, under most circumstances, occur 15 days after your arrest.
Although your license will be suspended automatically during this time period, the skilled DWI lawyers of the Law Offices of Tad Nelson & Associates will effectively represent you at this hearing and fight for your privilege to lawfully operated your motor vehicle in the state of Texas.
Don’t Give Harris County Prosecutors Evidence Against You
If you subject yourself to a Breathalyzer test, you’re basically handing evidence over to the prosecution. The prosecution will use your Breathalyzer, field sobriety test or blood test results against you if they have results. Fortunately, this too can be disputed as Breathalyzer test results are neither 100 percent error proof nor 100 percent accurate.

Our Houston criminal defense lawyer Tad Nelson, a former assistant district attorney, is board certified* in criminal trial law and has a tremendous track record of winning big criminal cases at trial. He has extensive experience when it comes to DWI cases and can effectively defend you.
Breathalyzer Arguments
There are many arguments that can be made in your defense against alcohol Breathalyzer results. If law enforcement did not follow proper protocol and procedure in administering tests, this can be deemed a violation of your constitutional rights and the evidence can be thrown out. In addition, the accuracy of Breathalyzer machines is also arguable. A person’s height, weight, medical condition and other factors are not often taken into consideration. Not to mention calibration issues and the condition of the machine itself. We will make all valid arguments in your defense in order to avoid serious DUI penalties.
Blood & Breath Test Refusal
If you’re a Texas motorist, and you operate your vehicle on public roadways in the state of Texas, you’ve already given Houston area police officers consent to perform breath, blood, and chemical testing on you if they suspect you of Driving While Intoxicated (DWI) or Driving under the Influence (DUI).
Implied Consent
There’s a legal standard in the state of Texas known as “implied consent” which means that, by operating a vehicle on public roads in the state of Texas, permission is given via “implied consent” to law enforcement to perform sobriety testing on you if they suspect you of being impaired.

Refusing Blood & Breath Tests
Refusing to take part in testing will automatically put you in a situation where you may face surcharges when you attempt to renew your Texas Drivers License and/or an outright Texas drivers license suspension.
It’s important to note that the implied consent law only applies to evidentiary tests performed in a controlled environment like a police station and excludes a legal requirement for field sobriety tests, portable breath tests, and DRE (drug recognition expert) tests.
Don’t hesitate to contact The Law Offices of Tad Nelson & Associates if you want to fight a DWI charge, a DWI-alcohol related offense, you want to fight the validity of tests conducted by the state, or you want to challenge the state because your rights were violated.
Failing DWI Sobriety Tests
Even if you failed the tests, we might still be able to defend you on the grounds of your Constitutional Rights being violated as a result of an unlawful search or an unlawful traffic stop by police. Tests conducted at police stations are not always accurate, and the personnel are not always trained to the highest suggested standards of competency.
In other cases, specimen contamination and other simple mistakes are made during the collection and storage of evidence that would be used against the defendant in a Houston criminal trial setting.
DWI Sobriety Test Refusal Defense
Houston DWI Lawyer Tad A. Nelson does not advocate an outright refusal of breath testing while in police custody at the police station.

What may happen is that the police officer might feel compelled to seek a warrant from a judge to perform a blood test, breath test, or even worse, a forced blood draw.
This is only possible if the police can show probable cause for such measures to be executed.
If the police officer can get a judge or magistrate to grant them a blood warrant, we’ll still have a few options at our disposal that may prevent blood evidence from being admissible in court.
Evidence could be blocked from court due to reasons involving an overstatement of the evidence by the arresting agency, bad science when it comes to the blood test, the omission of important information from warrant requests, and dishonesty by police.
Other Penalties For Blood & Sobriety Test Refusal
If the officer decides to take the extra step of getting a warrant for a forced blood draw or breath test, you’ll face additional penalties such as an immediate Texas Drivers License suspension and/or an assessment of surcharges when you eventually renew your Texas Drivers License.
However, it should be noted; there’s no penalty for refusing to take part in a DRE evaluation.
