Beer keg registration is legally required in many U.S. states where permanent markings or identification tags are affixed to kegs of beer upon retail sale. Furthermore, stores are often required to keep the record of tags which include the name and address of the buyer, the date and the address the beer will be served, and other pertinent information. Beer keg registration laws vary widely in their details and enforcement. The goal of keg registration is to prevent friends or relatives of legal-drinking age from purchasing kegs of beer for adolescent parties. Keg registration has been implemented in many states and it can be achieved several different ways. For example, permanent markings can be placed on each keg to identify when and where it was purchased. Recently, there was a study done to examine the associations between keg registration policy ratings and binge drinking, driving after drinking, and riding with a drinking driver among adolescents. There was a negative correlation between more comprehensive and stringent keg registration policies and all three behaviors. (Thomas, pg 3). Keg registration fits stated government policy because it outlines a process that can be easily followed and it reduces the use and abuse of alcohol amongst adolescents. The result being lower instances of teenage binge-drinking, drinking and driving, and driving with another teen that has been drinking.
