Can you have a passenger drinking in your car?

The answer depends on the specific laws in your jurisdiction. In general, it is not permissible to have an open container of alcohol in a car, even if the person drinking is a passenger. However, there are some exceptions to this rule, such as if the passenger is in a limousine or other private vehicle that is not being driven by the owner of the vehicle. It is always best to check with the local laws in your jurisdiction to be sure.
