One guest at the Arcadia High School prom won't have a date. But it may attract much of the attention. School chaperones will bring a police-style Breathalyzer to the annual formal dance next month, and they intend to test students who appear to have violated the school's no-drinking rule. Arcadia High School officials, whose action follows similar moves by other schools, say they hope to cut down on drinking--and driving--by the 1,200 students expected to attend the prom.
