What action can lead to a charge of 'Driving under the influence of alcohol by a minor'?

Having detectable alcohol in the system is a crucial factor that can lead to a charge of 'Driving under the influence of alcohol by a minor.' In Texas, the legal drinking age is 21, and for minors, any measurable amount of alcohol in their system while operating a vehicle can result in DUI charges. This is because the laws are stricter for drivers under 21, reflecting a zero-tolerance approach toward underage drinking and driving.

Even a small amount of alcohol can impair a minor's ability to drive safely, which is why the law focuses on the presence of alcohol, rather than the more lenient standards applied to adults. In contrast, the other options relate to scenarios that either do not inherently involve an alcohol-related offense for minors or apply to adults. For instance, having a blood alcohol content over 0.08% applies to individuals who are of legal drinking age and does not pertain to minors.
