You may drink alcoholic beverages in a vehicle on a public highway:

  1. As long as you aren't driving.
  2. If you are riding in the back seat.
  3. If you are riding in the back of a pick-up truck.
  4. Under no circumstances. ✓

Answer: D. Under no circumstances.

The correct choice is under no circumstances: you may not drink alcoholic beverages in a vehicle on a public highway.

Why this is the answer

The Texas handbook says it is illegal to have an open container of alcohol in a motor vehicle passenger area on a public highway, whether the vehicle is being operated, stopped, or parked. Because the rule applies even when the car is not moving, choices that focus on not driving or on where you sit do not create an exception. That is why the bank answer rules out drinking in the vehicle on a public highway.

Why the other answers are wrong

Remember it

If the container is open in the passenger area on a public road, the car does not have to be moving for it to be a violation.
