What alcohol consumption rule applies to drivers under 21 in Texas?

In Texas, the alcohol consumption rule for drivers under 21 is based on a zero tolerance policy. This means that if any detectable amount of alcohol is found in the system of a driver under the age of 21, it is considered illegal. The intent behind this law is to prevent drunk driving among younger and less experienced drivers, as even small amounts of alcohol can impair judgment and reaction times.

The zero tolerance legislation serves to emphasize the importance of responsible drinking and aims to protect young drivers and others on the road by promoting a strong message against underage drinking and driving. Consequently, it ensures that those under 21 are held to a stricter standard regarding alcohol consumption compared to older, legally allowed drivers.
