What is the meaning of "alcohol concentration" according to the Texas Penal Code?

"Alcohol concentration" as defined in the Texas Penal Code specifically refers to the number of grams of alcohol per 210 liters of breath. This measurement is commonly used in law enforcement and legal contexts to determine whether an individual is above the legal limit for driving under the influence. The breath analysis devices used by law enforcement operate based on this standard to ascertain the level of alcohol in a person's system accurately.

This definition is particularly significant because it is pertinent to how breathalyzer tests calculate blood alcohol content (BAC), allowing law enforcement to enforce DUI laws effectively. Understanding this measurement is crucial for any officer, as it directly relates to the enforcement of alcohol-related offenses.

While other options touch on relevant aspects of alcohol measurement, they do not align with the specific legal definition set forth in the Texas Penal Code. For instance, the number of grams of alcohol per 100 liters of blood refers to a different aspect of blood alcohol content that is not as commonly used in legal contexts.
