Montgomery County DWI Attorney - Brian Foley

If you have been arrested for DWI in Montgomery County, Texas, you need an experienced attorney who understands the law, the courts, and the local law enforcement agencies involved in these cases. Texas has strict DWI laws under Chapter 49 of the Texas Penal Code, which defines intoxication and outlines the legal thresholds that can lead to an arrest and conviction. Understanding these laws is critical when building a defense.


What Is Considered Intoxication Under Texas Law?

Under Texas Penal Code § 49.01(2), a person is legally intoxicated if they meet any one of the following criteria:


  1. Loss of normal use of mental faculties due to alcohol, drugs, or a combination of substances.

  2. Loss of normal use of physical faculties due to alcohol, drugs, or a combination of substances.

  3. Having a blood alcohol concentration (BAC) of 0.08 or higher at the time of operating a motor vehicle.


Each of these standards provides law enforcement officers with different ways to establish probable cause and make an arrest for DWI.


Loss of Normal Use of Mental Faculties

Alcohol and drugs can impair judgment, reasoning, concentration, and decision-making. If an officer believes a driver is confused, unable to follow instructions, or struggling with basic cognitive tasks, they may claim the driver has lost the normal use of their mental faculties. This can be demonstrated through field sobriety tests and officer observations.


Loss of Normal Use of Physical Faculties

Intoxication can also affect a person’s coordination, balance, and motor skills. If a driver is stumbling, has slurred speech, or cannot perform physical tasks as expected, an officer may argue that they have lost the normal use of their physical faculties. Field sobriety tests, such as the walk-and-turn or one-leg stand, are commonly used to assess this type of impairment.


Blood Alcohol Concentration (BAC) of 0.08 or Higher

Texas law sets a legal limit for blood and breath alcohol concentration at 0.08%. Even if a person does not appear impaired, they can still be charged with DWI if a chemical test shows a BAC at or above this threshold. Breath and blood tests are commonly administered after an arrest, though they are not always reliable and can be challenged in court.
