When you can’t drink and drive, why do you need a driver’s license to buy alcohol?
<|assistant|>
Some states require individuals to have a valid driver's license to prove their identity and age when purchasing alcohol. Without a driver's license, it can be difficult to verify someone's identity and whether they are of legal drinking age, thus prohibiting the sale of alcohol.
