The Difference Between DWI and DUI

Driving under the influence (DUI) and driving while intoxicated (DWI) are terms often used interchangeably, but under Texas law, they have distinct legal meanings. DUI typically refers to cases involving drivers under 21 years old who have any detectable amount of alcohol in their system, adhering to the state's strict "zero tolerance" policy for minors. 

On the other hand, DWI applies to individuals of any age who operate a motor vehicle while impaired due to alcohol or drugs, determined by a blood alcohol concentration (BAC) of 0.08% or higher.

Possible Defenses in DWI and DUI Cases

The exact strategy will depend on the unique circumstances in your particular case. These are some common areas we often explore: 

An Improper Traffic Stop 

One of the most common defenses in DWI cases is challenging the legality of the traffic stop. Under the Fourth Amendment, law enforcement officers must have reasonable suspicion to pull over a driver. If we can prove that the stop was made without valid legal grounds, any evidence gathered afterward, such as field sobriety or breathalyzer test results, may be suppressed, weakening the case against you.

Faulty Field Sobriety Tests 

Field sobriety tests are often used to assess impairment, but these tests are not always reliable. Physical conditions like medical issues, fatigue, or even nervousness can affect performance. Additionally, environmental factors such as uneven road surfaces may unfairly hinder a driver’s ability to perform the tests. We may be able to challenge the tests' validity in court and argue that their results do not conclusively indicate impairment.

Breathalyzer or Blood Test Errors 

Breathalyzer machines and blood tests are critical evidence in many DWI cases, but they are not infallible. Improper calibration, maintenance issues, or operator errors can yield inaccurate results. We can scrutinize the testing procedure and equipment to uncover potential flaws that might render the evidence inadmissible.
