Texas uses the Intoxylizer 5000 as its breath test machine.  Rather than discuss it in confusing and lengthy scientific concepts (which we’re happy to do in person), let’s discuss in general terms some if the problems associated with the machine.

Think of it as a scale in your bathroom that says you weigh anywhere from 50 to 170 lbs.  Not very helpful, is it?  This is for several compounding reasons.  First is the machine’s technology was created when the Atari video games were popular and Texas simply hasn’t found it cost-effective to upgrade.  Second is the machine piles assumption after assumption about the test-taker which may or may-not be true.

Also the machine – like any other mousetrap — can completely whiff on occasion.  The amount of ethyl alcohol it would take to score a false positive could fit on the tip of a pen as just one example.  The machine can be set off by GERD or gastro-intestinal reflux disease, can respond to environmental products used in the workplace, and has problems distinguishing diabetic shock from intoxication.

Again, we’re happy to discuss the science behind the Breath test in person… but understand just because the machine said it doesn’t mean it’s accurate!  It never hurts to scrutinize any test result.


Top 5 Biggest Mistakes People Make After They’re Arrested For DWI

1. Not consulting an attorney.

DWI laws in Texas are out of control. Many times people feel that if they made a mistake — that their prior good record combined with a rational prosecutor and Judge mean that they won’t be treated unfairly. Even if someone is lucky enough to draw such people on their case — the legislature has tied the prosecutor or Judges hands! There’s no deferred adjudication for DWI and related offenses. There are mandatory sur-charges costing thousands of dollars – and that’s just for starters!

The plain fact is that a DWI arrest is more severe than it looks. A skilled, experienced advocate is can assist in evaluating and fighting a DWI arrest.

2. Ignoring the Case

Being arrested can be a very humbling experience. Drunk driving arrests, though, need to be addressed quickly. There is virtually always a drivers license suspension which results from either a breath test refusal or failure and those deadlines run quickly. Unfortunately I’ll see people in denial over their arrest, but important rights can be lost with unnecessary delay.

3. Making Hurried Decisions

Again, an arrest for DUI, DWI or drunk driving is an extremely traumatic event. My experience is that over time, attitudes about the arrest change. It’s not uncommon for me to visit with someone that wants nothing more than to accept the charges and any and all punishment the State has in store for them — only to change their mind down the road based on changed perspective… And certainly the reverse happens too. I always encourage people arrested for DWI to “let the dust settle” in their lives before deciding to hire a lawyer. While it is important to act quickly with a dwi arrest, it’s bad to sacrifice common sense too.

4. Taking Legal Advice from Non-Lawyers.

There are all sorts of “experts” on DWI cases that don’t have any interest in your outcome. Yet many of these ‘experts’ still insist on giving you legal advice. A lawyer is professionally and ethically on the hook when they agree to represent you. Jailers, the bail-bondsman, or a court clerk who may only see you once in their lives may have a decent understanding of the legal machinations of how a DWI works… But getting 40, 50, or 60 percent correct information is a great way to make a bad mistake.

5. Losing Your Head.

I tell my clients that it’s important that they keep their cool. Some cases take a good amount of time to be resolved and that it doesn’t do anyone good to lose sleep over something that works at the speed of government. Many people drive themselves crazy with angst and worry, but good decisions aren’t made that way.
