Dram Shop Liability
Dram shop liability laws mean that if a customer buys a drink, leaves that location, and then causes harm, the owner of the place where the drink was served is legally responsible. Passing and enforcing dram shop liability laws reduced alcohol-related harms in numerous studies. For example, the percent of alcohol-related motor vehicle fatalities decreased by an average of 6.4% after passage of dram shop policies.
