What are the penalties for DUI and minors?

Generally speaking, in addition to suspension of driving privileges, the penalties for Driving Under the Influence of alcohol as a minor are as follows:

First Offense: Class C Misdemeanor. If the minor is under age 18, most courts require a parent or guardian to be present at every court appearance. Upon conviction, a minor may be fined, and will be required to perform community service. Additionally, the minor will be required to attend an alcohol awareness program sponsored by the Texas Commission on Alcohol and Drug Abuse within 90 days. If the minor fails to complete the alcohol awareness course within the 90-day period, the court may impose an additional license suspension of up to six months.

For a first offense, the minor may receive deferred adjudication; however, an order of deferred adjudication for DUI is considered a conviction. If the minor receives only one conviction for DUI (while a minor), that conviction may be expunged from his record after his 21st birthday.

Second Offense. Everything that applies to a first-offense conviction applies to a second conviction, with the following exceptions: The minor will be required to complete a minimum of 40 hours of community service. Furthermore, a second or any subsequent conviction may not be expunged from the minor's record; however, the minor may still receive deferred adjudication for a second offense.
