Thailand has introduced specific guidelines for alcohol vendors to assess customer intoxication before serving more drinks. This follows a regulation that prohibits the sale of alcohol to already intoxicated customers, as per Section 29 of the Alcohol Control Act. The guidelines published in the Royal Gazette aim to help vendors make informed decisions and avoid legal repercussions. Get today's headlines by email The regulation was announced last December but lacked clarity on how vendors should evaluate intoxication. On March 30, the Royal Gazette detailed methods for assessing a customer's level of drunkenness, describing physical, verbal, and behavioral indicators of intoxication. The Disease Control Department's director, Monthian Kanasawat, highlighted that vendors should watch for signs like impaired balance, motor control issues, and behaviors that may threaten public safety. Key methods outlined include three sobriety tests: a self nose-touching test, a foot-to-foot alternating test, and a single-leg counting test. Each method assesses coordination and balance, with specific criteria to determine intoxication. For instance, the nose-touching test involves closing the eyes and touching the nose, with signs of intoxication including noticeable hand tremors. These guidelines are part of efforts to ensure public safety and prevent alcohol-related harm. Sellers may face legal consequences if they serve alcohol to intoxicated customers who then cause damage or injury. Authorities urge drinkers to self-assess their sobriety and stop consuming alcohol if signs of intoxication appear. Looking forward, vendors and patrons are expected to adapt to these guidelines, which took effect on March 28. Effective implementation could lead to a decrease in alcohol-related incidents, promoting safer drinking environments. Authorities may monitor compliance and adjust measures as necessary.
