Purchasing a liquor liability policy doesn’t give a business license to stop checking customers’ identifications. Regardless of how well a business is insured, selling alcohol to underage individuals remains illegal -- and businesses that are caught doing so may face serious consequences. Additionally, many liquor liability policies have language that excludes any instances of underage drinking from their coverages. Thus, serving alcohol to underage customers can jeopardize a business’ coverage and leave the business dangerously exposed to the risks it’s trying to insure against.
