Texas practice test, alcohol and drugs

Alcohol law lives in the Penal Code here, and the set follows it there: intoxicated defined at 0.08, open container, DWI with a child passenger under 15, intoxication assault and manslaughter, and the enhancement that arrived in September 2025, DWI in a school crossing zone while the reduced limit applies is a state jail felony. Implied consent and the administrative revocation after a failed or refused test close the set, cited to chapters 724 and 524.

Each topic set draws up to 20 questions from that topic in the Texas bank and grades against our practice target of 80 percent. That target is our study goal. DPS publishes no pass mark for the Class C test, and none is implied here.

Intoxication in the Penal Code can come from what?

✓ Correct answer: Alcohol, a controlled substance, a drug, a dangerous drug, a combination of two or more of those substances, or any other substance

The definition names alcohol and then widens: a controlled substance, a drug, a dangerous drug, a combination of two or more of those substances, or any other substance introduced into the body can count. A driver impaired by a lawful prescription taken as directed can still meet it, which surprises many readers. (Texas Penal Code sec. 49.01(2)(A).)
