Want to know more about Texas and Houston DWI laws? Below, you’ll find a brief overview of Texas DWI facts, your rights, and actual excerpts of the DWI law in Texas.
What is DWI in Texas?
DWI stands for “driving while intoxicated.” Texas law defines intoxication as “not having the normal use of mental or physical faculties by reason of the introduction of alcohol, a controlled substance, a drug, a dangerous drug, a combination of two or more of those substances, or any other substance into the body; OR (b) having an alcohol concentration of .08 or more.” “Alcohol concentration” means the number of grams of alcohol per: (a) 210 liters of breath; (b) 100 milliliters of blood; or (c) 67 milliliters of urine.
What that means is, in Texas, a person is driving while intoxicated when:
- They are operating a motor vehicle in a public place and they have lost the normal use of their mental faculties or physical faculties; or
- They have an alcohol concentration of 0.08 or greater.

What Must Be Proven for Me to Be Convicted of DWI in Texas?
The state must prove beyond a reasonable doubt that you were operating a motor vehicle in a public place while intoxicated. For the state to prove you are intoxicated, it must present evidence to convince a jury beyond a reasonable doubt, to show you did not have the normal use of your mental or physical faculties or that you had an alcohol concentration of 0.08 or more.
I was Arrested for DWI: Does that Make Me Guilty?
No! Just because an officer brought you in for driving while intoxicated, it doesn’t automatically make you guilty. People are wrongly arrested for DWI all the time. An officer only needs probable cause to make an arrest. A jury must have proof beyond a reasonable doubt to convict someone of DWI.
Remember, a DWI arrest is based on an officer’s opinion, and there are two sides to every story. Let us provide a thorough analysis and second opinion of your case to ensure your rights are protected and you don’t get the short end of the stick.

Do I Have to Tell the Officer if I Have Been Drinking?
You do not have to tell the officer if you have been drinking. You don’t have to tell the officer anything other than your name and date of birth. You can just hand the officer your driver’s license. Once you have done that, you don’t have to tell them anything else, and you shouldn’t tell them anything else. Less is more.
What Happens when You Get Pulled Over for DWI in Texas?
Typically a DWI traffic stop will start like a normal traffic stop. The officer will pull you over and ask for your license and registration. You know it’s about to go downhill when the officer asks if you’ve been drinking. That is typically followed by the officer asking you to get out of the car and perform some field sobriety tests.
Do I have to Perform the Standardized Field Sobriety Tests?
No, you do not have to perform the field sobriety tests. These tests consist of at least three tests: the horizontal gaze nystagmus test (or HGN), the walk and turn test, and the one-leg stand. These are difficult things to do, even more so if you’ve never practiced them and you’re nervous. Performing these tests can make you look drunk even if you haven’t been drinking. You can refuse to do these tests.
Can I Refuse a Breathalyzer Test?
YES! If you are pulled over in Texas and a police officer suspects you are intoxicated, they will ask you to give a breath or blood sample. You can absolutely refuse to consent to a breathalyzer or breath test sample. If you refuse to give a breath sample, the officer may apply for a warrant to take a blood sample. If the officer gets a warrant signed by the judge, don’t fight with them.
If there are any issues with the warrant, we will fight those in court. A warrant that isn’t valid cannot be used in court. This means any evidence obtained as a result of the invalid warrant cannot be used at trial.
Can I Refuse a DWI-Related Blood Test?
YES! If a police officer requests a voluntary blood sample in Texas, you can refuse to give it to them. Frequently, the police go to a judge and get a search warrant for your blood. If the police get a search warrant for your blood, they can use whatever reasonable means necessary to get the blood out of your body. When the police have a search warrant, it is not a good idea to fight them. They have guns, and they’re probably going to win.
Can I Save My Driver’s License From Suspension After Being Arrested for DWI?
Maybe, but you have to act fast. You have only 15 days from the date of your arrest to request an Administrative License Revocation (ALR) hearing from the Texas Department of Public safety to save your license.

Could a Breathalyzer test Result Be Inaccurate?
Yes. There are a lot of physiological factors that cause breathalyzers to inaccurately measure a person’s blood alcohol concentration (BAC). There are many different types of breathalyzers that use different methods to measure a person’s BAC. Frequently, these devices give a reading that is not an accurate reflection of a person’s BAC.
A lawyer may be able to prove that the device gave an inaccurate measurement. They can use this information to show a jury just how much can go wrong with a breathalyzer in a trial.
Will a DWI conviction show up on my permanent record?
Maybe. If you get convicted of DWI, you may be eligible for a nondisclosure. A conviction could even prevent you from getting that dream job. For juveniles accused of DUI, it can prevent you from getting into the college of your choice or participating in extracurricular activities. A Houston DWI lawyer can fight against these charges.
Will I have an Ignition Interlock or Breathalyzer as a Bond Condition?
The court will likely require a breathalyzer as a condition of bond if you have a previous DWI conviction. Some Harris County courts require a breathalyzer while on bond for a first-offense DWI. Usually, for your first offense, a breathalyzer is only required as a condition of bond if there is an accident or a high breath or blood test.
Can I Drive a Car Without an Ignition Interlock if I have a Bond Condition Requiring an Ignition Interlock or Breathalyzer?
Yes. Texas Transportation Code §521.246 says: “A person to whom this section applies may operate a motor vehicle without the installation of an approved ignition interlock device if: (1) the person is required to operate a motor vehicle in the course and scope of the person’s employment; (2) the vehicle is owned by the person’s employer; (3) the employer is not owned or controlled by the person whose driving privilege is restricted; (4) the employer is notified of the driving privilege restriction; and (5) proof of that notification is with the vehicle.”
Could Being on the Keto Diet Have an Impact on My Breath Test?
Yes! Being on the keto diet, or being in ketosis, can have an impact on your breath test result. Ketosis causes a person’s body to create acetone. Acetone then converts to isopropyl alcohol. When isopropyl alcohol is combined with ethyl alcohol, breathalyzers can read the two together and give a falsely elevated reading.
According to the International Journal of Obesity, a man on the keto diet was unable to start a car equipped with an alcohol ignition interlock device. Your lawyer can investigate your case to determine if your result was a false positive. Then, they can use this information to protect your rights when evidence is presented to the court.
What is the Punishment for a DWI First Offense in Texas?
In Texas, a first-offense DWI punishment is up to 180 days in the county jail, up to a $2,000 fine, and potentially a license suspension from 90 days to one year.
What is the Punishment for a DWI First Offense with a BAC Over 0.15 in Texas?
In Texas, a first-offense DWI punishment with a BAC greater than 0.15 is up to one year in the county jail, up to a $4,000 fine, and potentially a license suspension from 90 days to one year.
Will My License Be Suspended if I am Convicted of a First-Offense DWI in Texas?
If you are convicted of a DWI in Texas and it is the first offense, your license is only suspended if the sentence is not probated. So if you are sentenced to probation, your license will usually not be suspended by the court. However, if you are sentenced to jail time, even if you don’t go to jail and receive credit for time served, your license will be suspended for a period of 90 days to one year.
What is the Punishment for a Second DWI Conviction in Texas?
In Texas, the punishment if you are convicted of a second offense DWI is up to one year in the county jail, up to a $4,000 fine, and a license suspension from 180 days to two years.
Can I Expunge a DWI From My Record?
It depends on what the outcome was. If the case was dismissed or you were found not guilty at trial, you are eligible for an expunction. Once we take a look at your case, we can help you determine if expunction is one of your legal options.
How do I Seal a DWI Conviction From My Record?
DWI convictions in Texas can be sealed from your record. A few elements must be met:
- The petitioner must not have been convicted of any other offense.
- The breath or blood test results must be below 0.15.
- There can not be an accident that involves another person.
The filing is called a petition for nondisclosure. Contact Blass Law PLLC today and we can help you through the whole process quickly.
