Driving While Intoxicated

The Legal Limit. The legal limit for intoxication in Texas is .08 blood alcohol concentration (BAC). However, drivers can be stopped and cited for impaired driving due to alcohol or other drugs regardless of BAC. Texas also has a zero tolerance law. For anyone under 21, it is illegal to drive with any detectable amount of alcohol.

How Much is Too Much? Impairment begins with the first drink. Gender, body weight, the number of drinks consumed and the amount of food in one’s stomach affect the body’s ability to handle alcohol. Women, younger people and smaller people, whether male or female, often have lower tolerances.
