Under what conditions are seller-servers not liable for damages caused by an intoxicated minor?

Seller-servers are not liable for damages caused by an intoxicated minor if the minor shows an apparently valid ID issued by a governmental agency that contains a physical description and photograph that matches the minor's appearance and shows him or her to be 21 or older. This policy is in place to ensure that seller-servers can trust the accuracy of the identification presented by the individual they are serving.

Option B is incorrect because a handwritten note from a guardian would not serve as a valid form of identification for determining the minor's age. Option C is incorrect because a minor's promise not to drink excessively does not absolve the seller-server of liability if the minor does drink and cause damages. Option D is incorrect because an expired ID is not considered a valid form of identification to prove a person's legal age.
