Overview of DWI Laws in Texas
DWI Defined Under Texas Law
The state of Texas is currently battling a drunk driving problem. The Texas Department of Transportation (TxDOT) states every 20 minutes a person is injured or killed by a drunk driver. These startling statistics have caused Texas to impose stiff laws for drunk drivers. Texas Penal Code § 49.04 states you’re committing a crime if you:- Operate a motor vehicle in a public place; and
- Are under the influence of drugs or alcohol.
How Does Texas Law Define Intoxication?
Texas law determines if a person is intoxicated by their blood-alcohol concentration or an assessment of their physical and mental faculties. Blood-alcohol concentration (BAC) is the number of grams of alcohol in your system, which is measured by chemical testing. Law enforcement uses blood analysis, urinalysis and breath analysis to determine BAC.Texas Penal Code § 49.01 measures BAC by number of grams of alcohol per:
Chemical testing is by no means a perfect process. Nearly all chemical testing samples are sent to a private or state crime lab, which could be contaminated by lab personnel. In addition, the machinery used to assess the samples could be outdated or inaccurate. This can lead to skewed results that can negatively affect your case. Another way for law enforcement to determine your impairment level is through field sobriety tests. Field sobriety tests are a series of physical exercises designed to evaluate your physical and mental faculties. While you may see a variety of field sobriety tests, only the tests standardized by the National Highway Traffic Administration (NHTSA) are viable in court. The tests standardized by NHTSA include the walk-and-turn, horizontal gaze nystagmus, and the one-leg stand. Although these field sobriety tests have been studied, field sobriety testing still has issues. Many factors can influence a person’s results. Even simple things such as a person’s shoes can lead to misleading results.
- 210 liters of breath;
- 67 milliliters of urine; or
- 100 milliliters of blood.
- 08 or higher for non-commercial drivers at or over the age of 21;
- 04 or higher for people with commercial driver’s licenses (CDL); and
- 02 or higher for people under the age of 21.
Implied Consent Laws in Texas
Texas has imposed laws for people who refuse chemical testing. These are referred to as implied consent laws, meaning if you drive on Texas public roads you’re implicitly submitting to chemical testing by law enforcement. Refusing to comply with testing can lead to an administrative license suspension. It’s important to remember that field sobriety testing isn’t included in implied consent laws. Even though implied consent laws are in place in Texas, you can still refuse testing. Chemical testing has flaws and your results may be misleading to authorities. In some cases, it’s best to refuse chemical testing so law enforcement has no concrete evidence of your DWI. You may be charged with DWI, but the prosecution will only have subjective evidence to present to the jury.If you refuse chemical testing, it’s important to understand there will be administrative consequences. You may not face criminal penalties, but your license will be suspended for a period of time. Listed below are the suspension periods for refusing chemical testing.
It’s also important to understand law enforcement can arrest you if they have probable cause you were driving under the influence. Probable cause is when an officer has a reasonable amount of suspicion, supported by circumstances, that a crime did or is taking place. This means you could be arrested even if you refuse chemical testing. Handling both an arrest and license suspension is unnerving. However, it may be the best possible option for you. Staying in jail for a short period of time is a lot less of a hassle than handling a DWI conviction. The prosecution won’t have any substantial evidence if you’re charged. In fact, you may not be charged at all if the District Attorney’s Office doesn’t think they have a case. You can also contest your suspension and you may be able to retain your license.
- 180 days for a first-time refusal; and
- 2 years for a second or subsequent refusal
