Houston DUI – Arraignment and Motion to Suppress?

Reader’s Question:

I just recently had the arraignment of my DUI case here in Houston, Texas and I pleaded not guilty so the case will continue. Would all be the evidence against me on my drunk driving arrest automatically be admissible in court?

When the prosecution begin to prepare their DUI case against you in Houston, Texas, they start by collecting all the evidence that supports their claim that you were really driving under the influence. But just because the prosecutors have collected it and want to present it at trial does not mean that it is automatically admissible. There are actually strict legal requirements that determine whether a piece of evidence can be presented at trial. A very important part of making your DUI case is arguing that the evidence that the prosecution wants to present at trial does not meet these requirements and therefore cannot be used against you.

Your DUI lawyer can formally request for motion to suppress to ask the court to exclude certain evidence from a trial because it was obtained illegally or improperly by the police officer. An example is that your DUI lawyer can argue that the officer did not have probable cause to pull you over. Suppression motion would argue that the officer’s belief that you were drunk driving was not “reasonable.” That means that the officer’s justification for your DUI stop should be something he actually saw. If motion to suppress will be successful, all the evidence that was made possible by pulling you over can also be suppressed.

Should You Perform a Houston Field Sobriety Test?

Reader’s Question:

My daughter has been arrested for drunk driving in Houston, Texas. She was asked to perform field sobriety tests and she failed them. I was told that these tests do not accurately determine driver impairment. Can she use this as a defense?

Yes, it’s true, field sobriety tests (FST’s) do not accurately measure the driver impairment for probable cause to support an arrest for DUI. So your daughter can use that as a defense in her DUI case in Houston, Texas. Many researchers observed that FST’s determine balance, reaction time and steadiness but concluded that a connection between these factors and driving ability was not apparent. That’s because neither a simple movement time nor steady stance is essential to the safe operation of a motor vehicle. The researchers conceded that FST’s may show the presence of alcohol but did not necessarily measure driving ability.

In general, police officers do not give the FST’s uniformly and there is no scientific basis for assuming these tests are valid. Many of these officers either improperly instruct the suspect driver on how to perform the tests or administer the wrong tests. A DUI defense lawyer can obtain a pre-trial suppression ruling to exclude the FSTs and their alleged indication of impairment due to lack of improper instructions and scientific foundation.
