With prom season approaching, some area schools are taking an extra step to make sure everyone has a good time, and avoid underage drinking.

From a story in the Times Union, chaperones will be carrying sensor devices to test students for alcohol. Ballston Spa schools already use them, and now they’ll be used at the Saratoga Springs High School junior-senior prom, at The Saratoga Springs City Center on May 14.

There was an incident that happened at a school dance, where several students got suspended for drinking and some were hospitalized. The Saratoga County District Attorney James Murphy III said that "Parents and teachers can only do so much." The sensor looks like an inhaler and it's also similar to what police carry while on road patrol. It will test the breath sample for alcohol and also a general blood alcohol content reading. This is to help a chaperone get an idea of the level of alcohol in a student's system.

Do you have any other ideas on how to prevent students from drinking at their prom?
