Albert Míreles, Jr., was stopped for speeding and arrested on suspicion of drunk driving. The arresting officer noted that Míreles had slurred speech and glassy eyes, had a strong оdor of alcoholic beverage on his breath, and swayed as he walked. Míreles also failed field sobriety tests. Breath tests administered about one hour later showed Míreles’ alcohol concentration to be 0.161 and 0.162. Because Míreles had a blood-alcohol concentration above the legal limit of 0.10,

the Texas Department of Public Safety suspended his driver’s license. Míreles requested an administrative hearing to challenge the suspension.
See
Tex. Transp. Code § 524.031. At the hearing, thе DPS offered the arresting officer’s notes and Míreles’ breath-test results, but offered no “extrapolation” evidence relating Míreles’ alcohol concentration when the tests were administered to his concentration when he was driving. The administrative law judge (ALJ) found that Míreles had an alcohol concentration of 0.10 or morе while driving and upheld his license suspension. Mí-reles appealed to the county court at law, contending that, without extrapolation evidence, the breath-test results were no evidence of his alcohol concentration while driving. The county court determined that the ALJ’s decision was supported by substantial evidence and affirmed, as did the court of appeals.
Míreles claims the court of appeals erred in affirming his license suspension because his breath-test results, which werе taken approximately one hour after he was stopped, were no evidence that his alcohol concentration was 0.10 or more at the time he was driving. He contends that extrapolation evidence, which would take into account his body weight and his food and alcohol consumption and relate his alсohol concentration when tested to the point in time when he was driving, was necessary to prove his alcohol concentration at the time he was driving. Míreles also argues that alcohol concentration and its extrapolation are scientific evidence subject to certain admissibility criteria, and that because the DPS did not offer proof of reliability, there is no evidence to support his license suspension. We disagree.
We first consider Míreles’ contention that, absent extrapolation evidence, his breath-test results are no evidence of his alcohol concentration while driving. Chapter 524 of the Texas Transportation Code outlines the driver’s-license-suspension procedure. See Tex. Transp. Code § 524.001. If a person is arrested for drunk driving and takes a test that shows his alcohol concentration to be 0.10 or higher, the DPS may suspend his driver’s license. See id. §§ 524.011, 524.012. A person whose license is suspended may request an administrative hearing to challenge the suspension. See id. § 524.031. At the hearing, the DPS must prove by a preponderance of the evidence that the person had an alcohol concentration of 0.10 or more while oрerating a motor vehicle in a public place. See id. § 524.035. Such a finding may not be made if the person had an alcohol concentration of less than 0.10 at the time the test was taken. See id. § 524.035(d). Nothing in the statutory framework specifically mandates extrapolation evidence.
The license-suspension statute serves the remedial рurpose of protecting public safety by quickly removing drunk drivers from the road.
See Ex parte Arnold,
When reviewing the sufficiency of the evidencе to support a criminal conviction, courts are required to “view all the evidence in the light most favorable to the verdict and determine whether any rationаl trier of fact could have found the essential elements of the crime beyond a reasonable doubt.”
Casillas v. State,
Míreles also claims that alcohol concentration and its extrapolation are scientific evidence subject to certain admissibility criteria, аnd that because the DPS did not offer proof of reliability, there is no evidence in the record to support his license suspension. It is true that breath-test results are sсientific evidence and that, to be proven reliable, they must satisfy a three-part test: (1) the underlying scientific theory must be valid; (2) the technique applying the theory must be valid; and (3) the technique must have been properly applied on the occasion in question.
See Hartman v. State,
Míreles’ breath-test results are morе than a scintilla of evidence to support the ALJ’s finding that Míreles had an alcohol concentration of 0.10- or more while driving. Accordingly, without hearing oral argument, undеr Rule 59.1 of the Texas Rules of Appellate Procedure, we grant Míreles’ petition for review and affirm the court of appeals’ judgment.
Notes
. The Legislature has amended the definition of intoxication to include persons with an alcohol concentration of 0.08 or more. See Act of May 28, 1999, 76th Leg., R.S., ch. 234, § 1(2)(B), 1999 Tex. Sess. Law Serv. 1082 (codified at Tex. Pen.Code § 49.01). This definition does not apply to this case, however, as it did not become effective until September 1, 1999. See id.
