Texas Penal Code 49.04 – Driving While Intoxicated (“DWI”)

WHAT IS DRIVING WHILE INTOXICATED (“DWI”) IN TEXAS?

The Texas law against driving while intoxicated, or “DWI,” prohibits operating a motor vehicle in a public place while intoxicated.

Texas Penal Code 49.04 - Driving While Intoxicated (DWI)

  • What is the legal limit for DWI in Texas? Texas Penal Code Section Section 49.01 defines “intoxication” in two ways: (1) a blood alcohol concentration (“BAC”) of 0.08 or more; or (2) 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.The subjective definition, or one’s loss of normal use of mental or physical faculties, does not require proof that a person’s blood alcohol concentration was above 0.08.For example, in Aguirre v. State, the defendant was arrested for DWI, and his blood test later showed a 0.075 blood alcohol concentration. But the other evidence showed he was going 102 miles per hour, had bloodshot eyes, slurred speech, and a can of beer in the car. The defendant also showed several clues of intoxication during the Standardized Field Sobriety Tests (SFSTs). Based on the evidence, the jury found him guilty, and the appellate court affirmed.
  • What is DWI .15 or higher in Texas? Texas law enhances a person’s first driving while intoxicated charge from a Class B misdemeanor to a Class A misdemeanor if a person’s blood alcohol concentration (BAC) is 0.15 or more.

(B) an offense under Section 49.07 or 49.08, if the vehicle operated was a motor vehicle;

(D) an offense under Article 6701l-2, Revised Statutes, as that law existed before January 1, 1984;

Failure to comply with an order entered under this subsection is punishable by contempt. For the purpose of enforcing this subsection, the court that enters an order under this subsection retains jurisdiction over the defendant until the date on which the device is no longer required to remain installed. To the extent of a conflict between this subsection and Subchapter I, Chapter 42A, Code of Criminal Procedure, this subsection controls.

Learn more.

WHAT ARE THE DEFENSES TO DRIVING WHILE INTOXICATED IN TEXAS?

The statute does not authorize specific defenses to driving while intoxicated, but the justification defenses, including necessity, are available for a person accused of DWI. A person accused of DWI may also attempt to negate at least one of the elements the State must prove at trial.

  • Can a person be convicted of DWI in Texas if the car was parked? Yes, depending on the circumstances. Texas law requires proof that a person was “operating” a vehicle while intoxicated, not that the person was actively driving at the time. The statute does not define “operating,” but Texas courts have determined whether a person operates a vehicle or watercraft when, based on the totality of the circumstances, the accused “took action to affect the functioning” of the vehicle or watercraft in a manner that would enable its use. See Kirsch v. State, 357 S.W.3d 645 (Tex. Crim. App. 2012).
  • Is a person required to submit to a DWI blood test in Texas? Texas law permits a person to refuse a blood or breath test if arrested for driving while intoxicated. But pursuant to Texas Transportation Code Section 724.012, police may obtain a warrant based on probable cause to extract a specimen of an arrestee’s blood. The Transportation Code also requires a person’s license to be suspended for 180 days if the person refuses to consent to the taking of a blood or breath specimen. Learn more.In Mitchell v. Wisconsin, the U.S. Supreme Court held that unconscious drivers suspected of drunk driving are subject to warrantless blood draws due to exigent circumstances, and a compelling need of the State to promote the paramount interest of highway safety.
  • What is a “public place” where a person can be arrested for DWI in Texas? Texas Penal Code Section 1.07(40) defines a “public place” as any place to which the public or a substantial group of the public has access and includes, but is not limited to, streets, highways, and the common areas of school, hospitals, apartment houses, office buildings, transport facilities, and shops.Private parking lots have been upheld as public places within the Penal Code definition. For example, in State v. Gerstenkorn, the defendant was arrested for driving while intoxicated in a gated community, with a security guard and limited public access. The appellate court determined the gated community fell within the definition of a public place.
  • What is the necessity defense to driving while intoxicated in Texas? Texas Penal Code Section 9.22 authorizes a person to commit otherwise criminal conduct if it was immediately necessary to avoid imminent harm, and the urgency of avoiding the harm clearly outweighed the harm sought to be prevented by the criminal conduct.The necessity defense is available for a driving while intoxicated charge. In Maciel v. State, the defendant and her brother went out drinking. Her brother drove her vehicle, but stopped in the road and started vomiting. The defendant got into the driver’s seat to move the car, but smoke came from under the hood as she tried to move it. An officer saw her, and she was arrested for DWI. The defendant argued it was necessary, and that she was not operating the vehicle.The Texas Court of Criminal Appeals held the defendant was operating the car, but was entitled to the defense of necessity. She admitted to attempting to move the car out of the road due to safety concerns.
  • Can taking medication before driving lead to a DWI in Texas? Yes. Texas Penal Code Section 49.10 provides it is not a defense to intoxication offenses if the person was “entitled to use the alcohol, controlled substance, drug, dangerous drug, or other substance.” This means that even if a person was driving under the influence of legally prescribed medication, the person may still be charged with an intoxication offense if the State proves loss of normal use of mental or physical faculties.For example, in Noska v. State, the defendant crashed into another vehicle around 9:00 a.m. on the way to her daughter’s school. She was under the influence of legally prescribed Xanax, Carisoprodol (“Soma”), Vicodin, and a small amount of opiates and cannabinoids. Her doctor warned her about driving after taking them. The defendant was convicted of intoxication manslaughter and intoxication assault, and the appellate court affirmed.

WHAT IS THE STATUTE OF LIMITATIONS FOR DRIVING WHILE INTOXICATED IN TEXAS?

The limitation period for Class A or B misdemeanor DWI is two years. The limitation period for driving while intoxicated enhanced to a third degree felony is three years.

  • When is a person formally charged for statute of limitations purposes in Texas? A person is formally charged when an information or indictment is presented. Texas Code of Criminal Procedure article 12.07 explains an information is “presented” when it is filed “by the proper officer in the proper court.” According to article 12.06, an indictment is “presented” when signed and approved by a grand jury, and filed with the proper court. The State must present an information or indictment within the applicable limitation period.

DRIVING WHILE INTOXICATED IN TEXAS

Driving while intoxicated in Texas is operating a vehicle in a public place while legally intoxicated. Intoxication depends on a person’s loss of normal use of mental and physical faculties, but may also be shown by a person’s blood alcohol concentration of 0.08 or more. DWI is an enhanceable offense in Texas, meaning the more times a person commits the offense, the higher the penalties.

TEXAS DRIVING WHILE INTOXICATED COURT CASES

The case law regarding driving while intoxicated in Texas illustrates the wide range of consequences of violating the statute.

  • In Bigon v. State, the defendant was driving home with his 8-year-old son when he hit another vehicle head-on, killing the two occupants. He had a 0.227 BAC an hour after the crash. He was convicted of felony murder with the underlying felony as driving while intoxicated with a child passenger under 15 years old, and the appellate court affirmed.
  • In Miles v. State, the defendant crashed into a limousine, but left the scene before police arrived. A tow-truck driver followed the defendant, and blocked him in to wait for police. The defendant was arrested for driving while intoxicated, but argued his citizen’s arrest was illegal. The Texas Court of Criminal Appeals held a tow-truck driver was authorized by article 14.01(a) of the Texas Code of Criminal Procedure to make a citizen’s arrest of the defendant for DWI.
