What is generally not allowed in Maryland concerning the sale of alcoholic beverages?

The practice regarding the sale of alcoholic beverages in Maryland is heavily regulated, with specific rules concerning the hours during which sales can occur. Generally, in Maryland, the sale of alcoholic beverages is not permitted before 6:00 AM or after 2:00 AM. This regulation is designed to control the hours of operation for establishments that sell alcohol, aiming to promote public safety and reduce alcohol-related incidents during late-night hours.

The other choices reflect practices that either do not have the same universal restrictions or are outright incorrect regarding Maryland's alcohol laws. For example, there are no restrictions that limit sales of alcoholic beverages to only weekdays; many establishments are permitted to operate on weekends as well. Additionally, selling alcohol without a valid license is illegal, but this does not pertain to a specific time regulation. Finally, the statement about sales being restricted to wine only is misleading, as Maryland allows a variety of alcoholic beverages to be sold, not just wine. Thus, the hours of sale are the most definitive restriction concerning the regulation of alcoholic beverages in Maryland.
