Information about Fighting the Breathalyzer
If you failed your DWI breath test in Houston, TX, it still may be possible to beat it. If it is just a little over the limit, it is possible to obtain a Dismissal prior to trial, depending on other facts and evidence from the arrest. If the breath test results are way over the .08 limit &dash like 2 and 3 times – the chances of litigating the results in a trial are much greater.
One of many ways to beat a breath test failure case, either before or during trial, is by showing that the breath test itself is is invalid and is therefore inadmissible as “scientific evidence&lrdquo;.
Under the Discovery Statute we can obtain evidence from DPS’s Office of the Scientific Director that can potentially prove the invalidity of breath test results.
Under DPS’s new (as of 2011) Standard Operating Guidelines, failed breath test results can be suppressed – that is – thrown out as evidence – if they were not taken and analyzed in compliance with these guidelines. Therefore, even if you fail your breath test, an experienced defense attorney such as Carl Haggard may be able to prove the test was invalid. In this event, failing the breathalizer doesn’t count against you.
Legal Defenses Against DWI Breath Test
Below are some examples of defenses The Haggard Law Firm uses at trial to prove failed breath test results are invalid and get them thrown out:
- Invalid procedures were used prior to obtaining the results
- Improper calibration or improper adjustment of calibration (per the SOG’s)
- Faulty machinery
- Lack of proper certification by the operator of the breath test machine
- Improper chain of custody of the breath sample
- Improper maintenance of evidence
- Fraud, incompetence, destruction of evidence or other issues related to the technical supervisor’s work
- Problems with the performance records of operators including their certification exam results
- Using an intoxilyzer without an embossed “Evidential Instrument” certification
- Maintenance records not organized and detailed enough to allow another technical supervisor to give an opinion in a trial on the machines’s maintenance history
If you plead guilty to your DWI in Houston it will be on your record forever. There is no option to seal or expunge a DWI conviction. A DWI conviction will go on your driving record which may cause your insurance rates to go up. DPS surcharges for DWI convictions range from $1000 to $2000 a year for 3 years.
Not every breath test case will have some or even one of these issues above. But if pleading guilty to your DWI is not an option then we need to do Discovery in the case to find out.
