Liability Issues Both your customers and you can be liable for what happens after they leave. Nothing can add to that liability, but you can take additional steps to reduce that liability by making an Alcohol Alert machine available for them. Alcohol Alert helps protect you because it’s a self-administered test, and a screening device. The machine never says it’s OK to drive; it just indicates BAC levels and warns against driving as the levels increase toward the legal limit of .08%. The results of the self-test can not be used in court because admissible tests must be administered by a trained expert. In addition, there must be a printout of the test results, and the test must be conducted on a state certified machine. Your staff can use the Alcohol Alert as the reason to stop serving customer when necessary. Free tokens for staff are available to be used for this purpose. Obviously if a staff member witnesses a customer testing over the limit, they should encourage the customer not to drive while impaired. Taking this kind of action demonstrates the establishment has a policy that protects both the customer and the bar.
