It is legal to drive with an alcoholic beverage container that has been opened only if the container is:

  1. Under the front seat.
  2. In the glove department.
  3. In the trunk. ✓

Answer: C. In the trunk.

An opened alcoholic beverage container is legal only if you keep it in the trunk.

Why this is the answer

The handbook says that if you carry alcohol in your vehicle, the container must be sealed and unopened. Once it is open, it has to be kept in the trunk or another place where passengers do not sit. The same passage also says an open alcohol container may not be kept in the glove box. That is why the trunk is the legal place listed here.

Why the other answers are wrong

Remember it

Remember it this way: sealed and shut, or open in the trunk, never in the glove box.
